Is Dentistry a Science? - The Atlantic
"It’s much less scientific—and more prone to gratuitous procedures—than you may think."



"e have a fraught relationship with dentists as authority figures. In casual conversation we often dismiss them as “not real doctors,” regarding them more as mechanics for the mouth. But that disdain is tempered by fear. For more than a century, dentistry has been half-jokingly compared to torture. Surveys suggest that up to 61 percent of people are apprehensive about seeing the dentist, perhaps 15 percent are so anxious that they avoid the dentist almost entirely, and a smaller percentage have a genuine phobia requiring psychiatric intervention.

When you’re in the dentist’s chair, the power imbalance between practitioner and patient becomes palpable. A masked figure looms over your recumbent body, wielding power tools and sharp metal instruments, doing things to your mouth you cannot see, asking you questions you cannot properly answer, and judging you all the while. The experience simultaneously invokes physical danger, emotional vulnerability, and mental limpness. A cavity or receding gum line can suddenly feel like a personal failure. When a dentist declares that there is a problem, that something must be done before it’s too late, who has the courage or expertise to disagree? When he points at spectral smudges on an X-ray, how are we to know what’s true? In other medical contexts, such as a visit to a general practitioner or a cardiologist, we are fairly accustomed to seeking a second opinion before agreeing to surgery or an expensive regimen of pills with harsh side effects. But in the dentist’s office—perhaps because we both dread dental procedures and belittle their medical significance—the impulse is to comply without much consideration, to get the whole thing over with as quickly as possible.

The uneasy relationship between dentist and patient is further complicated by an unfortunate reality: Common dental procedures are not always as safe, effective, or durable as we are meant to believe. As a profession, dentistry has not yet applied the same level of self-scrutiny as medicine, or embraced as sweeping an emphasis on scientific evidence. “We are isolated from the larger health-care system. So when evidence-based policies are being made, dentistry is often left out of the equation,” says Jane Gillette, a dentist in Bozeman, Montana, who works closely with the American Dental Association’s Center for Evidence-Based Dentistry, which was established in 2007. “We’re kind of behind the times, but increasingly we are trying to move the needle forward.”

Consider the maxim that everyone should visit the dentist twice a year for cleanings. We hear it so often, and from such a young age, that we’ve internalized it as truth. But this supposed commandment of oral health has no scientific grounding. Scholars have traced its origins to a few potential sources, including a toothpaste advertisement from the 1930s and an illustrated pamphlet from 1849 that follows the travails of a man with a severe toothache. Today, an increasing number of dentists acknowledge that adults with good oral hygiene need to see a dentist only once every 12 to 16 months.

Many standard dental treatments—to say nothing of all the recent innovations and cosmetic extravagances—are likewise not well substantiated by research. Many have never been tested in meticulous clinical trials. And the data that are available are not always reassuring.

The Cochrane organization, a highly respected arbiter of evidence-based medicine, has conducted systematic reviews of oral-health studies since 1999. In these reviews, researchers analyze the scientific literature on a particular dental intervention, focusing on the most rigorous and well-designed studies. In some cases, the findings clearly justify a given procedure. For example, dental sealants—liquid plastics painted onto the pits and grooves of teeth like nail polish—reduce tooth decay in children and have no known risks. (Despite this, they are not widely used, possibly because they are too simple and inexpensive to earn dentists much money.) But most of the Cochrane reviews reach one of two disheartening conclusions: Either the available evidence fails to confirm the purported benefits of a given dental intervention, or there is simply not enough research to say anything substantive one way or another.

Fluoridation of drinking water seems to help reduce tooth decay in children, but there is insufficient evidence that it does the same for adults. Some data suggest that regular flossing, in addition to brushing, mitigates gum disease, but there is only “weak, very unreliable” evidence that it combats plaque. As for common but invasive dental procedures, an increasing number of dentists question the tradition of prophylactic wisdom-teeth removal; often, the safer choice is to monitor unproblematic teeth for any worrying developments. Little medical evidence justifies the substitution of tooth-colored resins for typical metal amalgams to fill cavities. And what limited data we have don’t clearly indicate whether it’s better to repair a root-canaled tooth with a crown or a filling. When Cochrane researchers tried to determine whether faulty metal fillings should be repaired or replaced, they could not find a single study that met their standards.

“The body of evidence for dentistry is disappointing,” says Derek Richards, the director of the Centre for Evidence-Based Dentistry at the University of Dundee, in Scotland. “Dentists tend to want to treat or intervene. They are more akin to surgeons than they are to physicians. We suffer a little from that. Everybody keeps fiddling with stuff, trying out the newest thing, but they don’t test them properly in a good-quality trial.”

The general dearth of rigorous research on dental interventions gives dentists even more leverage over their patients. Should a patient somehow muster the gumption to question an initial diagnosis and consult the scientific literature, she would probably not find much to help her. When we submit to a dentist’s examination, we are putting a great deal of trust in that dentist’s experience and intuition—and, of course, integrity."



"Throughout history, many physicians have lamented the segregation of dentistry and medicine. Acting as though oral health is somehow divorced from one’s overall well-being is absurd; the two are inextricably linked. Oral bacteria and the toxins they produce can migrate through the bloodstream and airways, potentially damaging the heart and lungs. Poor oral health is associated with narrowing arteries, cardiovascular disease, stroke, and respiratory disease, possibly due to a complex interplay of oral microbes and the immune system. And some research suggests that gum disease can be an early sign of diabetes, indicating a relationship between sugar, oral bacteria, and chronic inflammation.

Dentistry’s academic and professional isolation has been especially detrimental to its own scientific inquiry. Most major medical associations around the world have long endorsed evidence-based medicine. The idea is to shift focus away from intuition, anecdote, and received wisdom, and toward the conclusions of rigorous clinical research. Although the phrase evidence-based medicine was coined in 1991, the concept began taking shape in the 1960s, if not earlier (some scholars trace its origins all the way back to the 17th century). In contrast, the dental community did not begin having similar conversations until the mid-1990s. There are dozens of journals and organizations devoted to evidence-based medicine, but only a handful devoted to evidence-based dentistry.

In the past decade, a small cohort of dentists has worked diligently to promote evidence-based dentistry, hosting workshops, publishing clinical-practice guidelines based on systematic reviews of research, and creating websites that curate useful resources. But its adoption “has been a relatively slow process,” as a 2016 commentary in the Contemporary Clinical Dentistry journal put it. Part of the problem is funding: Because dentistry is often sidelined from medicine at large, it simply does not receive as much money from the government and industry to tackle these issues. “At a recent conference, very few practitioners were even aware of the existence of evidence-based clinical guidelines,” says Elliot Abt, a professor of oral medicine at the University of Illinois. “You can publish a guideline in a journal, but passive dissemination of information is clearly not adequate for real change.”

Among other problems, dentistry’s struggle to embrace scientific inquiry has left dentists with considerable latitude to advise unnecessary procedures—whether intentionally or not. The standard euphemism for this proclivity is overtreatment. Favored procedures, many of which are elaborate and steeply priced, include root canals, the application of crowns and veneers, teeth whitening and filing, deep cleaning, gum grafts, fillings for “microcavities”—incipient lesions that do not require immediate treatment—and superfluous restorations and replacements, such as swapping old metal fillings for modern resin ones. Whereas medicine has made progress in reckoning with at least some of its own tendencies toward excessive and misguided treatment, dentistry is lagging behind. It remains “largely focused upon surgical procedures to treat the symptoms of disease,” Mary Otto writes. “America’s dental care system continues to reward those surgical procedures far more than it does prevention.”

“Excessive diagnosis and treatment are endemic,” says Jeffrey H. Camm, a dentist of more than 35 years who wryly described his peers’ penchant for “creative diagnosis” in a 2013 commentary published by the American Dental Association. “I don’t want to be damning. I think the majority of dentists are pretty good.” But many have “this … [more]

Opinion | Why You Want to Eat This Baby Up: It’s Science - The New York Times
"Researchers are beginning to ask why some people want to squeeze puppies and others want to sniff babies."



"Cute Overload
Anyone who has been on the internet lately knows that cuteness can get weird: lemurs with Keane-painting eyes, infants dressed as peapods, cats with toast on their heads. The internet offers up achingly sweet “cute porn” because those images grab our attention. There’s something almost aggressive about the way we crave cuteness.

Several years ago, the actress Leslie Bibb perched next to Conan O’Brien’s desk and riffed about a baby so cute that it drove her crazy. She pantomimed her extreme reaction to the infant by gritting her teeth and clenching her fists.

A social psychologist named Oriana Aragón, who was then teaching at Yale, happened to be watching. In the days that followed, she found herself pondering a subject that doesn’t usually receive much attention from the scientific community: cuteness.

Dr. Aragón realized that feelings of tenderness can be so overwhelming that they spill over into a behavior that she calls “cute aggression.” An example, she told me, is “when you see a grandparent pinching a baby’s cheeks and saying, ‘I want to eat you up.’” In fact, sometimes baby-talk can sound downright serial-killer-ish if you take it out of context. You might find yourself telling a puppy that you want to squish it — even though, of course, you’re doing just the opposite and gently caressing it.

Dr. Aragón and her colleagues at Yale undertook what are probably the world’s first attempts to scientifically prove the existence of cute aggression. In an adorable experiment, she and her research partners handed volunteers bubble wrap, then showed them a parade of images. Dr. Aragón found that people popped more bubbles when looking at, say, a photo of a kitten than of an adult cat — suggesting that the cutest images do seem to prompt the urge to crush or squeeze.

Because the cute-overload feeling lends itself to study, it may help to reveal the parts of our minds devoted to nurturing that have heretofore been hidden.

Katherine Stavropoulos, a neuroscientist and clinical psychologist at the University of California at Riverside, has conducted a study on the neural circuitry that is active during cuteness-overload. She asked volunteers to wear caps outfitted with sensors that measure brain activity, and then showed them images of wee little animals. Her results suggested that “cute-aggression” involves the reward system in the brain. In other words, it feels good.

But why? “It’s just a completely open question,” Dr. Aragón, who now works at Clemson, told me. Even so, she points out, it’s reasonable to assume that our extreme reaction to cuteness is evolution’s way of making sure that parents do the relentless work of nurturing children. To perpetuate the species, parents must feel driven to hold their babies for hours — and that might explain why the urge to squeeze gets mixed into a cocktail of tender emotions."

[also here: https://threadreaderapp.com/thread/1102604887223750657.html ]

"Something I've been meaning to say about The Tragedy of the Commons. Bear with me for a small thread on why our embrace of Hardin is a stain on environmentalism. tldr: we’ve let a flawed metaphor by a racist ecologist define environmental thinking for a half century. 1/

Hardin’s article, published in Science, turned 50 this past December. Since then, tens of millions of students have been taught its core message. Every individual seeks to exploit the commons. In doing so they unsustainably overuse our shared resources to the ruin of all. 2/

Google Scholar gives me a current citation count of 38730 (!). Most articles on environmental politics use the phrase at some point or another. It has permeated our lexicon like few other concepts. Here is the original Science essay, btw: http://science.sciencemag.org/content/162/3859/1243
3/

(Side note: Hardin’s piece actually drew on a much earlier 1833 pamphlet by William Forster Lloyd about the dangers of overgrazing the English countryside. Worth a read for those so inclined: https://www.jstor.org/stable/1972412?seq=1#page_scan_tab_contents ) 4/

That this metaphor offers some essential insight is taken for granted. A generation of scholarship builds on its back, including in political science and economics. But does it? That's much less clear. 5/

As Susan Cox points out, British commons were exclusive to a defined set of individuals + this use itself was regulated. Commons as an institution worked but were undermined by other factors, including the efforts by the rich to accumulate more land http://dlc.dlib.indiana.edu/dlc/bitstream/handle/10535/3113/buck_NoTragedy.pdf?sequence=1&isAllowed=y 6/

So the metaphor is not actually grounded in an empirically accurate representation of the commons. Other scholars have more strongly contested the logic of Hardin's argument. These range from friendly amendments (Ostrom) to wholesale critiques. 7/

This would all be an academic argument if not for the intellectual roots of Hardin's metaphor and thinking - roots that too few environmentalists acknowledge. 8/

Hardin wasn't a social scientist or on an expert on social organization. Instead, he was a Human Ecology prof at UC Santa Barbara (my home institution) where he taught until his 1978 retirement. (Morbid side note: he and his wife killed themselves in a 2003 suicide pact.) 9/

Have you read Hardin's Science essay lately? It's a mind-numbingly racist piece. And not in a subtle way that demands 2019 woke analysis. Spend the 20 minutes and do it. It’s an ethical mess from beginning to end. 10/
There are headings like “Freedom to Breed is Intolerable”, under which Hardin imagines the benefits that might accrue if “children of improvident parents starve to death”, an outcome stymied (a bad thing to him), by the welfare state. 11/

[image]

For these reasons, he campaigned against such programs as Food for Peace. A few paragraphs later: “If we love the truth we must openly deny the validity of the Universal Declaration of Human Rights.” I think you get the idea. 12/

And this is par for the course for Hardin, who was also a passionate eugenicist. Oh hey! Look who is classified by the Southern Poverty Law Center as a known white nationalist: https://www.splcenter.org/fighting-hate/extremist-files/individual/garrett-hardin 13/

Lets quote the SPLC: 14/

SPLC has painful quotes from his later work. “Diversity is the opposite of unity, and unity is a prime requirement for national survival” (1991). “My position is that this idea of a multiethnic society is a disaster…we should restrict immigration for that reason.” (1996) 15/

And here is another one, again as an image because, no thanks do I want my twitter history to pop up when people search these things. 16/ [image]

And here is Hardin making an appearance in the infamous racist “Mainstream Science on Intelligence” op-ed. I could go on (and the SPLC does), but you get the idea. http://www.intelligence.martinsewell.com/Gottfredson1997.pdf 17/

Fast forward. Probably you’ve read articles on the intellectual network behind Trump’s nativist, racist demagoguery. Many mention the very influential anti-immigration activist John Tanton, and his Federation for American Immigration Reform (FAIR): https://www.washingtonpost.com/outlook/2018/09/27/shadowy-network-shaping-trumps-anti-immigration-policies/
18/

And who was on FAIR’s board, and a close friend of Tanton? Yep, Hardin. https://www.splcenter.org/fighting-hate/extremist-files/group/federation-american-immigration-reform 19/

In my mind, it’s not that Hardin WOULD HAVE been a Trumper. It's that he WAS a Trumper before Trump was a Trumper. He helped build the entire intellectual movement Trump has since exploited. 20/

Now, lots of awful people have left noble ideas that outlive them. But in Hardin’s case, the intellectual legacy is largely built on top of his racist, flawed Science that we still treat as gospel and uncritically assign in undergraduate courses year after year. 21/

It is not a legacy based on empirical scholarship, but on a metaphor that doesn't quite hold water. Not that you would know any of this from the anodyne retrospectives that have sprouted up in the last several months celebrating his article's 50th anniversary. 22/

Fifty years later, the environment community needs to stop ignoring this dark intellectual heritage. A movement that seeks to define a just, vibrant climate future needs to tear away the veneer, and choose what of Hardin to keep and what to discard. 23/

We must ask: on what empirical basis do we accept his metaphor? How do we teach his metaphor? Do we contextualize its racist roots? Is it productive to the social transformation necessary to save the world from the climate crisis? 24/

Not undertaking this honest examination will perpetuate its own (common) tragedy and make our intellectual heritage a form of unwitting support for some of the ugliest social forces at play in the world today. 25/25"

Talks | Refiguring Planetary Health, Building Black Futures

We cannot have a healthy planet that sustains all human beings as long as the systemic oppression of Black and Indigenous peoples continues. And yet, prominent environmental science institutions concerned with conservation and climate change often fail to address this oppression or their role in perpetuating it. In this talk, we will explore how histories of scientific racism and eugenics inform current scientific policies and practice. Cynthia Malone will work with various forms of freedom practice, from hip hop to science fiction to scholarship in the Black Radical Tradition, to consider alternative visions for planetary health that advance both environmental stewardship and liberation from oppressive ideologies and systems.

The Spirit of the Water Bear

In this talk, Claire Pentecost will give an introduction and reading of Spirit of the Water Bear, a young adult novel set in a coastal town in the Carolinas. The novel’s protagonist, Juni Poole, is a 15-year-old girl who spends much of her time exploring the natural world. Inevitably, she finds herself confronting the urgency of a crisis that has no end, namely climate change and the sixth great extinction. Through experiences of activism, she finds comrades who feel environmental and political urgency much as she does, and learns that she has a place in the ongoing struggle for environmental justice. The book is a work of “Cli-Fi” or climate fiction, featuring Juni’s adventures, but it is also a work of “Cli-Phi” or climate philosophy, featuring conversations and musings on the nature of our existential predicament.

#GLITCHFEMINISM

Legacy Russell is the founding theorist behind Glitch Feminism as a cultural manifesto and movement. #GLITCHFEMINISM aims to use the digital as a means of resisting the hegemony of the corporeal. Glitch Feminism embraces the causality of ‘error’ and turns the gloomy implication of ‘glitch’ on its ear by acknowledging that an error in a social system disturbed by economic, racial, social, sexual, cultural stratification, and the imperialist wrecking-ball of globalization—processes that continue to enact violence on all bodies—may not be ‘error’ at all, but rather a much-needed erratum. The digital is a vessel through which our glitch ‘becoming’ realises itself, and through which we can reprogramme binary gender coding. Our ‘glitch’ is a correction to the machine—f**k hegemonic coding! USURP THE BODY—BECOME YOUR AVATAR!

EXHIBITION
Curated by REFRESH collective members Heather Dewey-Hagborg and Dorothy R. Santos, the exhibition title is inspired by artist Morehshin Allahyari’s work defining a concept of “refiguring” as a feminist, de-colonial, and activist practice. Informed by the punk ethos of do-it-yourself (DIY), the 18 artists featured in Refiguring the Future deeply mine the historical and cultural roots of our time, pull apart the artifice of contemporary technology, and sift through the pieces to forge new visions of what could become.

The exhibition will present 11 new works alongside re-presented immersive works by feminist, queer, decolonial, anti-racist, and anti-ableist artists concerned with our technological and political moment including: Morehshin Allahyari, Lee Blalock, Zach Blas*, micha cárdenas* and Abraham Avnisan, In Her Interior (Virginia Barratt and Francesca da Rimini)*, Mary Maggic, Lauren McCarthy, shawné michaelain holloway*, Claire and Martha Pentecost, Sonya Rapoport, Barak adé Soleil, Sputniko! and Tomomi Nishizawa, Stephanie Syjuco, and Pinar Yoldas*.

Visualizing the Speed of Light
"Light is fast! In a recent series of animations, planetary scientist James O’Donoghue demonstrates just how fast light is…and also how far away even our closest celestial neighbors are. Light, moving at 186,000 mi/sec, can circle the Earth 7.5 times per second and here’s what that looks like:

[video]

It can also travel from the surface of the Earth to the surface of the Moon in ~1.3 seconds, like so:

[video]

That seems both really fast and not that fast somehow. Now check out light traveling the 34 million miles to Mars in a pokey 3 minutes:

[video]

And Mars is close! If O’Donoghue made a real-time animation of light traveling to Pluto, the video would last over 5 hours. The animation for the closest undisputed galaxy, Seque 1, would last 75,000 years and 2.5 million years for the Andromeda galaxy animation. The farthest-known objects from Earth are more than 13 billion light years away. Light is slow!

https://www.cnn.com/2018/12/16/world/greta-thunberg-cop24/index.html ]

"15 year old activist Greta Thunberg speaks truth to power at the UN COP24 climate talks:

"My name is Greta Thunberg. I am 15 years old. I am from Sweden.

I speak on behalf of Climate Justice Now.

Many people say that Sweden is just a small country and it doesn't matter what we do.

But I've learned you are never too small to make a difference.

And if a few children can get headlines all over the world just by not going to school, then imagine what we could all do together if we really wanted to. But to do that, we have to speak clearly, no matter how uncomfortable that may be.

You only speak of green eternal economic growth because you are too scared of being unpopular. You only talk about moving forward with the same bad ideas that got us into this mess, even when the only sensible thing to do is pull the emergency brake.

You are not mature enough to tell it like is. Even that burden you leave to us children. But I don't care about being popular. I care about climate justice and the living planet.

Our civilization is being sacrificed for the opportunity of a very small number of people to continue making enormous amounts of money.

Our biosphere is being sacrificed so that rich people in countries like mine can live in luxury. It is the sufferings of the many which pay for the luxuries of the few.

The year 2078, I will celebrate my 75th birthday. If I have children maybe they will spend that day with me. Maybe they will ask me about you. Maybe they will ask why you didn't do anything while there still was time to act.

You say you love your children above all else, and yet you are stealing their future in front of their very eyes.

Until you start focusing on what needs to be done rather than what is politically possible, there is no hope. We cannot solve a crisis without treating it as a crisis.

We need to keep the fossil fuels in the ground, and we need to focus on equity. And if solutions within the system are so impossible to find, maybe we should change the system itself.

We have not come here to beg world leaders to care. You have ignored us in the past and you will ignore us again.

We have run out of excuses and we are running out of time.

We have come here to let you know that change is coming, whether you like it or not. The real power belongs to the people.

Thank you.""

School strike for climate - save the world by changing the rules | Greta Thunberg | TEDxStockholm - YouTube
"Greta Thunberg realized at a young age the lapse in what several climate experts were saying and in the actions that were being taken in society. The difference was so drastic in her opinion that she decided to take matters into her own hands. Greta is a 15-year-old Stockholm native who lives at home with her parents and sister Beata. She’s a 9th grader in Stockholm who enjoys spending her spare time riding Icelandic horses, spending time with her families two dogs, Moses and Roxy. She love animals and has a passion for books and science. At a young age, she became interested in the environment and convinced her family to adopt a sustainable lifestyle. This talk was given at a TEDx event using the TED conference format but independently organized by a local community."

10,000 ["How to Send a Message 10,000 Years into the Future."]
"This is The Ray Cat Solution:

1. Engineer cats that change colour in response to radiation.

2. Create the culture/legend/history that if your cat changes colour, you should move some place else."



"In the 1980's, a curious project was proposed by two scientists : why not creating a breed of radioactive cats that would change colors when they are next to nuclear waste?

OFFICIAL SELECTION Pariscience 2015 - International Science Film Festival -- This film is on free access - if you like it or if you feel it should be seen, feel free to share it.

THE RAY CAT SOLUTION
Philosophers Françoise Bastide and Paolo Fabbri were part of the Human Interference Task Force, employed by the US Department of Energy and Bechtel Corp at the Yucca Mountain Nuclear Waste Repository in 1981. Their solution consisted of two steps:

Engineer a cat that changes colour in response to radiation.

Create a culture around this cat, such that if your cat changes colour, you should move someplace else.

This requires a combination of scientific work in biology as well as social sciences and art, and there are many questions to consider:

• How do we actually engineer this cat?
• What are some of the scientific challenges?
• How do we create this culture?
• What types of art are more effective?

and much more..."



"WHAT DOES THE RAY CAT MEAN FOR YOU?
This project is as multi-faceted as it can be. Everyone's expertise and opinions are welcome and encouraged. We are here to challenge each other, ask questions, learn and share knowledge and perspectives with eachother.

SCIENCE
How do we engineer a colour change in response to radiation?
Where do we start and what are the challenges?

ART & DESIGN
How do we send a message 10,000 years into the future?
What types of projects do we need to do in order to create this culture?

POLITICS AND PHILOSOPHY
How is science funded?
What are the regulations and current perspectives on this type of project?
Should ray cats be allowed to exist?"



"SHARE, DISCUSS, CREATE, INVENT
This isn't a project. It is a movement. It doesn't have a particular direction, nor is it meant to. We are starting out with a blank canvas, and many directions we could go. The movement exists simply from those who choose to visit it and contribute.

We encourage creativity, and discussion. Question each other's ideas, inspire new ones, think out of the box and listen to what people have to say. Every mistake made and every question asked is progress.

This movement and process is bigger than the cats. This page also exists as a challenge to artists, scientists and anyone. How provocative are your ideas? Does this project have any less or perhaps more meaning than yours? Are your ideas truly creative and innovative?

There are many questions to answer, and even more questions to ask. We are in our first few years of another ten thousand. If nothing else, we at least have some time.

"Have encountered a few people recently who’ve been enamoured with education research and how “science” can help us teach better. These people seem to confuse the explanatory and predictive powers of the physical sciences with what social sciences can do.

This is not to disparage the social sciences - they are important and valuable. But it worries me that some in education seem to think “science” can help us teach in the same way “science” helps us build rockets.

There’s a lot going on with the current enthusiasm for research in education, and it’s great that it gives teachers a focus for discussion and sharing ideas, but it’s not the panacea some seem to think."

"Red Delicious was A+ in its original incarnation. Then folks kept grafting from bud sports (=sometimes a tree throws a branch that's a little different, it's normal) w darker & darker fruit. Selected for color instead of quality. 100+ yrs later we now have purple foamballs.

[quoting: "If I had a time machine I would 100% make sure that the person who named the Red Delicious apple was brought to justice"
https://twitter.com/faithchoyce/status/1055944025121771520]

(2/) Weirdly this makes some evolutionary sense. When confronted w a variety of otherwise identical fruit (say, bins of apples at the store), humans go for the darkest red ones.

In nature, that's how you eat the ripe ones & leave bb fruit to mature.

(3/) So. All other things being equal, if you have multiple apple varieties at the store, the darkest red ones tend to sell the fastest. It's not hard to see how that wound up being the priority for deciding which Red Delicious variants to graft.

(4/) Tl;dr a lot of the stuff that the food movement blames on "bad agriculture" or w/e is ... really just the result of a lot of micro-scale human decisions that made sense on their own. Then they snowball into something weird.

(5/) Also when I worked in fruit breeding the weirdest thing would happen. Us in the breeding program would wind up with our favorite cultivars. We liked the ones with a lot of flavor: strong, balanced acidity & sweetness with a lot of aroma.

(6/) There was this one blueberry that had this amazing rich flavor. Thick, jammy with a little bit of blackberry to it. mmmmmm

(7/) But when we actually did the flavor testing? Let civilians eat our new berry crosses?

They LOOOVED the most watery, insipid, shitty berries. Kept giving them top marks, and our favorite big-flavor berries always wound up in the middle.

(8/) IIRC the top-testing blueberry from that program during my time there was Meadowlark. Bless its heart, it's a great bush- but the fruit is a bland-ass water bean. Its max flavor level is a faint whiff of violets.

(9/) Anyway, it seems like every other thinkpiece about ~food these days~ has obligatory remarks on how The Scientists Are Breeding Crops For Durability Instead of Flavor.

lmao fuck that, we keep TRYING to breed for flavor & getting sabotaged by y'all on the taste panels

(10/) Again, there's some really complex human systems stuff going on in our produce markets. Like asking why so many ppl seem to prefer bland fruit. We'd really be able to help ourselves out if we actually ... looked at that?

(11/) But it wraps the story up in a neat little bow to blame ~science~ so sure let's do that instead.

-cut to scientists hissing Gollum-style over the 3 good berry plants from their field trials that never made it to market because The People Have Spoken- 🤣

(12/) Hrmmm replies have turned into a "let's hate on the plebes who don't appreciate fruit like ~we~ do" sesh.

The entire point of this thread was, there's a HUGE spectrum of flavors out there most of us don't ever encounter & we don't know what we don't know.

(13/) Statistically speaking, MOST OF US in the ol' u s of a are secretly one of those majority of people who like shitty bland fruit, AND WE'LL NEVER KNOW IT."

Mary Midgley - The Gifford Lectures
"An interviewer from the Guardian newspaper once wrote that Mary Midgley ‘may be the most frightening philosopher in the country: the one before whom it is least pleasant to appear a fool’. In a series of books, particularly Beast and Man (1978), Evolution as a Religion (1985),Science as Salvation (1992; her 1990 Edinburgh Gifford Lectures) and Science and Poetry(2001), Midgley offers a trenchant critique of science’s pretence to be much more than it actually is, of the ways in which science often becomes a religion.

Perhaps appropriately, Midgley the scourge of ‘science as religion’ was born to an army and Cambridge college chaplain, Canon Tom Scrutton, and educated in a boarding school in Charles Darwin’s old home, Downe House. Perhaps Midgley’s fascination with science came from her mother’s side; Lesley Hay’s father was an engineer who built the Mersey tunnel. It was in the Downe House library that Midgley first picked up Plato, and, in her own words, ‘thought it was tremendous stuff’ (although in later life perhaps Aristotelian questions have proved more fascinating). By this time, Midgley also realised that she was not a Christian, a position her clergyman father accepted rather matter-of-factly. Nevertheless, Midgley remains convinced that ‘the religious attitude’ is essential to human thriving, and in her work has repeatedly defended the place of religious belief (rather than particular religious beliefs) against its arrogant critics from the sciences.

A number of Midgley’s contemporaries at Somerville College, Oxford, went on to achieve philosophical distinction in later life, including Iris Murdoch, another Edinburgh Gifford Lecturer, with whom Midgley became a close friend. Midgley relished doing philosophy in wartime Oxford, partly because there wasn’t ‘an endless gaggle of young men’ to offer distraction. But she considered it ‘providential’ that she did not get the post she applied for at St. Hugh’s College, and left Oxford, since she thought that the then-prevailing climate of Oxford philosophy would have destroyed her as a philosopher.

She met Geoffrey Midgley while at Oxford. They married in 1950 at Newcastle, where Geoffrey had a job. She then raised a family and did not take up a post in the Department of Philosophy in Newcastle until 1962, where she remained until she retired as Senior Lecturer when the department closed.

Midgley’s animated critique of scientism—science become religion—has been taken by some, especially scientists, as an attack on science itself. This may partly be because Midgley seems much more adept at demolishing others’ positions than in stating her own clearly. In fact, Midgley’s critique of science should be seen against her own metaphor of the philosopher as plumber: the philosopher, like the plumber, engages in an activity that civilisation depends on, but it is an activity which people only notice and require when certain rather essential workings have gone wrong. At her best, Midgley is a ‘science critic’ (using the word ‘critic’ in the way it is used in ‘literary critic’), seeking dialogue with the important activity called science to enable it to do more good and less harm in the modern world. Midgley’s contribution to this project is perhaps largely that of negative criticism. However, her friendship with and support for James Lovelock, the scientist who developed the Gaia hypothesis (that the planet earth as a whole is a living system), tells us a lot about her positive beliefs. Presumably, in Lovelock, she finds a scientific approach that is more congenial and conducive to human flourishing."

Mary Midgley, 99, Moral Philosopher for the General Reader, Is Dead - The New York Times
"The biologist Stephen Rose, writing in The Times Literary Supplement in 1992, called Dr. Midgley “a philosopher with what many have come to admire, and some to fear, as one of the sharpest critical pens in the West.”

Andrew Brown, writing in The Guardian in 1981, called her “the foremost scourge of scientific pretension in this country.”

Dr. Midgley unhesitatingly challenged scientists like the entomologist Edward O. Wilson and the biologist, and noted atheist, Richard Dawkins. By her lights they practiced a rigid “academic imperialism” when they tried to extend scientific findings to the social sciences and the humanities.

In place of what she saw as their constricted, “reductionistic” worldview, she proposed a holistic approach in which “many maps” — that is, varied ways of looking at life — are used to get to the nub of what is real.

One challenge came in 1978 in her first book, “Beast and Man: The Roots of Human Nature,” based on a conference she had organized on that slippery, perennial subject as a visiting scholar at Cornell University.

She was later asked to revise her original manuscript to reflect her critical reaction to Professor Wilson’s best-selling 1975 book, “Sociobiology: The New Synthesis” (“a volume the size of a paving stone,” she wrote later in a well-received 2005 autobiography, “The Owl of Minerva”). She described the field of sociobiology as a kind of reactionary “biological Thatcherism.”

Sociobiology — the application of gene-centered theories of natural selection to the social life of organisms — was not itself overly controversial, especially, as Professor Wilson originally used it, in the study of ants and insects. Dr. Midgley, given her own interest in emphasizing humans’ animal nature — that “we are not, and do not need to be, disembodied intellects” — praised parts of Professor Wilson’s book.

What provoked her and others was his hypothesis that the tenets of sociobiology could be applied to humans. That idea, according to scholars, threatened to radically revise generally accepted notions of human nature.

“The term ‘human nature’ is suspect because it does suggest cure-all explanations, sweeping theories that man is basically sexual, basically selfish or acquisitive, basically evil or basically good,” Dr. Midgley wrote in “Beast and Man.”

In “The Owl of Minerva,” she wrote that the need to address Professor Wilson’s concepts had distracted readers from her crucial topic: “the meaning of rationality itself — the fact that reason can’t mean just deductive logic but must cover what makes sense for beings who have a certain sort of emotional nature.”

She added that “Beast and Man” remained “the trunk out of which all my various later ideas have branched.”

Dr. Midgley took pains to distinguish between the important contributions of science and the philosophy of “scientism,” in which “prophets,” she wrote, decree that science is “not just omnicompetent but unchallenged, the sole form of rational thinking.”

“We do not need to esteem science less,” she continued. “We need to stop isolating it artificially from the rest of our mental life.”

Dr. Midgley did not align herself with any specific school of thought: She wrote that moral philosophy and plain “common sense” often covered the same ground. She targeted what she saw as some of the basic errors of modern scientific orthodoxy, including misplaced objectivity, the exclusion of purpose and motive, and the propensity to depersonalize nature.

The very titles of her books — among them “Science as Salvation: A Modern Myth and Its Meaning” (1992) and “Evolution as a Religion” (1985) — and even irreverent chapter headings, like “Knowledge Considered as a Weed Killer,” conveyed her stance against what she called the “parsimonious” worldview of science.

In 1979, in the journal Philosophy, she issued a scathing critique of Professor Dawkins’s widely popular book “The Selfish Gene,” taking issue with what she called his “crude, cheap, blurred genetics.”

In that book, Professor Dawkins suggested that evolution is a product of an innate drive in genes to perpetuate themselves, “selfishly,” through the vehicle of a given species, and that the behavior of living things is in service to their genes.

Dr. Midgley explained her disagreement years later in The Guardian, writing: “Selfish is an odd word because its meaning is almost entirely negative. It does not mean ‘prudent, promoting one’s own interest.’ It means ‘not promoting other people’s’ or, as the dictionary puts it, ‘devoted to or concerned with one’s own advantage to the exclusion of regard for others.’”

She refuted the notion that selfishness underpinned all life.

“Just as there would be no word for white if everything was white, there could surely be no word for selfish if everyone was always selfish,” she wrote, adding, “Selfishness cannot, then, be a universal condition.”

In a long career as a published philosopher, Dr. Midgley addressed a great number of subjects. Evolution, the importance of animals, the role of science in society, cognitive science, feminism and human nature all came under her scrutiny.

She ranged more widely in “Science and Poetry” (2001), in which she considered the place of the imagination in human life. She found excesses of materialism and fatalism in human life, discussed the unusual compatibility of physics and religion, and approved of philosophical and metaphorical aspects of the Gaia hypothesis, which looks at the earth as a living system.

“With this book,” Brian Appleyard wrote in The Sunday Times of London, “Professor Midgley establishes herself as the most cool, coherent and sane critic of contemporary superstition that we have.”"

Mary Midgley obituary | Education | The Guardian
"Philosopher who brought a sharp critical intelligence and a gift for vivid metaphor to her writing on human behaviour"



"In 1931, Mary was sent to Downe House. This progressive boarding school started in Charles Darwin’s old home, although by the time Mary was a pupil it had moved to Ash Green, near Newbury. She won a scholarship to Oxford to read Classical Greats and, arriving at Somerville College in 1938, became one of a strikingly able and forceful group of women philosophers. Elizabeth Anscombe had arrived at Oxford the year before, Iris Murdoch, who became a close friend, was an exact contemporary, and Philippa Foot arrived a year later. The work of this interesting quartet of thinkers has recently become the object of revived interest in the contribution of women to philosophy during the last century.

Mary graduated with a first in 1942 and for the remainder of the war worked mainly as a civil servant. From 1945-47 she was secretary to the classical scholar Gilbert Murray, after which she returned to philosophy, starting a thesis on the psychology of Plotinus. She tutored at Somerville and lectured at the University of Reading from 1948 until 1950.

At this point it looked as if an academic career of a familiar shape might be opening up. But instead, in 1950, she married a fellow philosopher, Geoffrey Midgley, whom she had first met in Oxford in 1945. He was lecturing at what later became the University of Newcastle upon Tyne, but was then King’s College of the University of Durham. He and Mary set up house together in Newcastle and had three sons over the next five years.

Mary turned to journalism, reviewing children’s books and novels for the New Statesman and the BBC Third Programme. She also read extensively in (among other things) psychology, anthropology, evolutionary theory and animal behaviour, becoming particularly interested in the views of such pioneers of ethology as Lorenz and Tinbergen. Her excellent autobiography, The Owl of Minerva (2005), gives a vivid account of this first half of her life.

It is unlikely that she would ever have become a professional philosopher in quite the mould of many of her contemporaries, since she had little taste for the logical and linguistic issues that were the focus of mainstream work in the 1950s and 1960s, and which remain the focus of much contemporary work. She said later that she was glad to have escaped when she did from the ambience of Oxford, finding it overly narrow and competitive.

The break in her career kept her very much aware of the need for philosophy in wider debate and, as she said herself, she was concerned “to bring academic philosophy back into its proper connection with life, rather than letting it dwindle into a form of highbrow chess for graduate students”.

In 1965 she returned to teaching philosophy, as a lecturer and later senior lecturer at Newcastle. It was not until this point, when she was over 50, that she began to publish the work for which she later became famous.

In 1980 she took early retirement to have more time to write and travel, and she was writing up to the end. Her final book What is Philosophy For? was published last month. Her work had already begun to be widely known at the time she retired, and she was invited to address numerous conferences and festivals. She became involved in campaigning for animal welfare (and for several years she chaired the RSPCA’s committee on animal experimentation), for environmental awareness and against the arms trade. She also appeared frequently on television and radio, presenting the case for animals and the environment and against scientific hubris. Her speaking and writing were always direct and vigorous and were informed by wide reading, a sharp critical intelligence and a gift for vivid metaphor. The drive of her thought is throughout sane and humane."

Jantar Mantar: The Astronomical Observatories of Jai Singh
"Between 1724 and 1730 Maharajah Sawaii Jai Singh II of Jaipur constructed five astronomical observatories in north India. The observatories, or "Jantar Mantars" as they are commonly known, incorporate multiple buildings of unique form, each with a specialized function for astronomical measurement. These structures with their striking combinations of geometric forms at large scale have captivated the attention of architects, artists, and art historians world wide, yet remain largely unknown to the general public.

jantarmantar.org presents the observatories through a variety of media, making it possible to explore and learn about these historic sites through interactive panoramic tours, time lapse sequences, and 3D models as well as articles, drawings, and historic texts. It is a comprehensive resource for exploring the observatories in depth.

Welcome to the new jantarmantar.org!
The redesigned website was launched in October 2015 - and we are still hard at work refining the content and tweaking the design. As new pages and features are added, they will be announced through our Facebook and Instagram pages, so follow us there!

New to jantarmantar.org is the Learn section, featuring a wealth of information about the observatories and the unique instruments Jai Singh created to observe celestial objects.
But more than that, the Learn section also features projects you can do to learn more about the observatories and sky observation without a telescope."

The Blog of Phyz: Be careful with your parabolic mirror
"[image]

Let's say you you were into making solar ovens. Let's say that you decided a few years ago to make the best solar oven ever. Further, let's stipulate that you saw a nearly meter-diameter Direct TV antenna on the side of the road. An idea happened. You rushed to the local plastics store and bought highly reflective Mylar and glued it to the antenna.

Your solar oven was pretty amazing. While the hot spot wasn't super small, it was hot. Really hot. It can pasteurize a liter of water in 15 minutes.

And now you work at the Exploratorium and you think that you might bring it to work for grins. If you forget it in the back of the your Outback face up on a sunny day near the solstice, well, it can melt the molding in a fairly impressive way. I think I was lucky that my car didn't catch on fire.

[image]

You might be wondering how I could make such a mistake? I had a lot to carry into the Exploratorium, and the mirror wouldn't fit on the cart. I planned on coming back in a few minutes, but I got busy doing something else, and it slipped my mind. Coming back in the afternoon, I sat in the driver seat and looked into the rear view mirror.

[image]

Uh oh.

If you want to make your own parabolic mirror, you can find some excellent instructions here.

You're Not Hallucinating. That's Just Squid Skin. | Deep Look - YouTube
"Octopuses and cuttlefish are masters of underwater camouflage, blending in seamlessly against a rock or coral. But squid have to hide in the open ocean, mimicking the subtle interplay of light, water, and waves. How do they do it? (And it is NOT OCTOPI)"



"--- How do squid change color?

For an animal with such a humble name, market squid have a spectacularly hypnotic appearance. Streaks and waves of color flicker and radiate across their skin. Other creatures may posses the ability to change color, but squid and their relatives are without equal when it comes to controlling their appearance and new research may illuminate how they do it.

To control the color of their skin, cephalopods use tiny organs in their skin called chromatophores. Each tiny chromatophore is basically a sac filled with pigment. Minute muscles tug on the sac, spreading it wide and exposing the colored pigment to any light hitting the skin. When the muscles relax, the colored areas shrink back into tiny spots.

--- Why do squid change color?

Octopuses, cuttlefish and squid belong to a class of animals referred to as cephalopods. These animals, widely regarded as the most intelligent of the invertebrates, use their color change abilities for both camouflage and communication. Their ability to hide is critical to their survival since, with the exception of the nautiluses, these squishy and often delicious animals live without the protection of protective external shells.

But squid often live in the open ocean. How do you blend in when there's nothing -- except water -- to blend into? They do it by changing the way light bounces off their their skin -- actually adjust how iridescent their skin is using light reflecting cells called iridophores. They can mimic the way sunlight filters down from the surface. Hide in plain sight.

Iridophores make structural color, which means they reflect certain wavelengths of light because of their shape. Most familiar instances of structural color in nature (peacock feathers, mother of pearl) are constant–they may shimmer when you change your viewing angle, but they don't shift from pink to blue."

The logic of Buddhist philosophy goes beyond simple truth | Aeon Essays
"When Western philosophers look East, they find things they do not understand – not least the fact that the Asian traditions seem to accept, and even endorse, contradictions."



"An abhorrence of contradiction has been high orthodoxy in the West for more than 2,000 years. Statements such as Nagarjuna’s are therefore wont to produce looks of blank incomprehension, or worse. As Avicenna, the father of Medieval Aristotelianism, declared:
Anyone who denies the law of non-contradiction should be beaten and burned until he admits that to be beaten is not the same as not to be beaten, and to be burned is not the same as not to be burned.


One can hear similar sentiments, expressed with comparable ferocity, in many faculty common rooms today. Yet Western philosophers are slowly learning to outgrow their parochialism. And help is coming from a most unexpected direction: modern mathematical logic, not a field that is renowned for its tolerance of obscurity."

Losing Earth: The Decade We Almost Stopped Climate Change - The New York Times
"Editor’s Note
This narrative by Nathaniel Rich is a work of history, addressing the 10-year period from 1979 to 1989: the decisive decade when humankind first came to a broad understanding of the causes and dangers of climate change. Complementing the text is a series of aerial photographs and videos, all shot over the past year by George Steinmetz. With support from the Pulitzer Center, this two-part article is based on 18 months of reporting and well over a hundred interviews. It tracks the efforts of a small group of American scientists, activists and politicians to raise the alarm and stave off catastrophe. It will come as a revelation to many readers — an agonizing revelation — to understand how thoroughly they grasped the problem and how close they came to solving it. Jake Silverstein"

quantum distributions for Sarah Baartman | The Offing
"“Baartman lived in poverty, and died in Paris of an undetermined
inflammatory disease in December 1815. After her death, Cuvier dissected
her body, and displayed her remains. For more than a century and a half,
visitors to the Museum of Man in Paris could view her brain, skeleton and
genitalia as well as a plaster cast of her body.”

from Sarah Baartman’s Wiki page, referencing
Sara Baartman and the Hottentot Venus:
A ghost story and a biography
by Clifton C. Crais and Pamela Scully

here is what is true:
a black body radiator be a star that Rayleigh Jeans Law fails to approximate
black bodies be emitting spectral radiance but those white men act like they ain’t ever seen us i mean
who gave men permission to approximate the black body?
to contain us? how have men deluded themselves that they are close enough to touch
us? why must they demand black bodies self-sacrifice
in ultraviolet? that is why must we give
all of us to them until we have nothing left? until we approach
infinity? why must they make us approach infinity?
why must they contrast us against the omnipotent?
why must they deny us our humanity in death? why must they torture us
with the focus they have been beaming on to black bodies?
why are they so hungry? like we shine but it ain’t enough? for them
black bodies is never enough
and our purgatory ain’t either how dare they
in fact we the black bodies refuse and denounce lawful men
and their sickly approximations because
we the black bodies understand each other at visible frequencies
without a dissection or death—which is to say witness
us the black bodies rejoice to become mortals again because
here is what is true:
a black body radiator be in thermodynamic equilibrium which is to say
a black body be at rest yes let the black bodies rest
in peace watch us the black bodies converge into an infrared sunset so
blessed be the tail of a distribution curve like where my thigh meets my ass
mine own black body emblematic and
fundamentally mine"

[via: "quantum distributions for Sarah Baartman" is by Lena Blackmon, a Black woman undergrad studying materials science (applied physics) @Stanford. I dreamed of a poem like this: a Black woman writing herself & her history into science, with accurate science!"
https://twitter.com/IBJIYONGI/status/1012346837427109889

"This poem is also my answer to everyone who has ever asked me why it is a problem to compare Black people to dark matter:
black bodies be emitting spectral radiance but those white men act like they ain’t ever seen us i mean
who gave men permission to approximate the black body?"

"If you're writing about Black people and trying to use physics analogies, you better imagine that Black scientists exist and not just reference popular science writing by white people. Talk to a Black scientist. There are many @ #BlackandSTEM."

"Part of Black liberation has to be imagining Black experts in science too. Black people don't just write poetry. We also do science. Sometimes, like Lena, we do both. When you don't imagine that, you don't imagine Lena, and I need you to imagine Lena. I made a department for her."

"I am proud of everything we have published in Back of the Envelope, but it was work like Lena's that drove my initial thinking behind creating the department. I wanted somewhere that a Black woman wouldn't feel like she had to choose between her scientific and literary identities"]

Labs, courts and altars are also traveling truth-spots | Aeon Essays
"Throughout history, people found truth at holy places. Now we build courts, labs and altars to be truth spots too"



"But is longevity in a particular location always needed in order for a place to make people believe? Some truth-spots travel: they inhabit a place only temporarily. Sometimes a portable assemblage of material objects might be enough to consecrate an otherwise mundane place as a source for legitimate understandings – but only for the time that the stuff is there, before it moves on. But if a church or lab or courtroom can be folded up like a tent and pitched someplace else, can it really sustain its persuasive powers as a source for truth? Here is how it works."

Decolonising Science Reading List – Chanda Prescod-Weinstein – Medium
"In April, 2015, one of the most visible topics of discussion in the Astronomy community was the planned Thirty Meter Telescope and protests against it from Native Hawaiians who didn’t want it built on Mauna Kea. I wrote a lot about this on social media, spending some significant time trying to contextualize the debate. This reading list was originally created in response to requests for where I was getting some of the information from. A lot of people asked me about what I’d been reading as reference points for my commentary on the relationship between colonialism and what we usually call “modern science.”

In August 2016 I updated to announce: I’m happy to report that Sarah Tuttle and I will be contributing to this list with our own publications in future thanks to this FQXi grant that we are co-I/PI on: Epistemological Schemata of Astro|Physics: A Reconstruction of Observers. The grant proposal was based on a written adaptation of a speech I gave at the Inclusive Astronomy conference, Intersectionality as a Blueprint for Postcolonial Scientific Community Building.

As part of this work, I’ve continued to expand the reading list, which seems to have become a global resource for people interested in science and colonialism. As I originally said, I make no claims about completeness, about updating it regularly, or even ever coming up with a system for organizing it that I find to be satisfactory. You’ll find texts that range from personal testimony to Indigenous cosmology to anthropology, to history to sociology to education research. All are key to the process of decolonising science, which is a pedagogical, cultural, and intellectual set of interlocking structures, ideas, and practices. This reading list functions on the premise that there is value in considering the ways in which science and society co-construct. It is stuff that I have read all or part of and saw some value in sharing with others.

I am especially indebted to the #WeAreMaunaKea movement for educating me and spurring me to educate myself."

PIG/PORK: Archaeology, Zoology and Edibility: Pía Spry-Marqués: Bloomsbury Sigma
"Pigs unite and divide people, but why? Pig/Pork explores the love-hate relationship between humans and pigs through the lenses of archaeology, biology, history and gastronomy, providing a close and affectionate look of the myriad causes underlying this singular, multi-millennial bond.

What is it that people in all four corners of the world find so fascinating about the pig? When did the human obsession with pigs begin, how did it develop through time, and where is it heading? Why are pigs so special to some of us, but not to others? Pig/Pork sets out to answer these and other porcine-related questions, examining human-pig interactions across the globe through time, from the Palaeolithic to the present day. The book dissects pig anatomy and behaviour, and describes how this knowledge plays a major role in the advance of the agricultural and medical sciences, among others. The book also looks closely at the history of pig-human interaction; how they were domesticated and when, how they affected human history through their diseases, and how they have been involved in centuries of human conflicts, with particular reference to the story of the Iberian Jews and Muslims at the time of the Inquisition. The book goes on to look at how pigs' characteristics and our relationship with them have combined to produce many of the world's great dishes. All this is accompanied by a liberal peppering of pork recipes and the stories behind them, along with facts, wisdom and porker lore, providing a thought-provoking account of where our food comes from, both historically and agriculturally, and how this continues to influence many parts of our behaviour and culture."

Kilauea: A Beginner’s Guide to Hawaii’s Sublime Lava - The Atlantic
"But Western scientists were not the first people to encounter Hawaii’s volcanoes. Native Hawaiians have lived on the islands, and among the volcanoes, for more than 900 years. And their history, literature, and culture all recognize the reality of living near such a powerful phenomenon.

(A brief language note: Everyone who lives in the archipelago is called a “Hawaii resident.” The term “Hawaiian” is reserved for someone with native Hawaiian ancestry. This distinction is regularly made on the islands, including in the state constitution.)

“There’s aʻa or pahoehoe, the rough lava or the smooth lava,” said Kuʻualoha Hoʻomanawanui, a professor of literature at the University of Hawaii at Manoa. “But the word for both of them is Pele.”

Pele is the Hawaiian deity of volcanoes, lava, and fire—but deity in its Western sense doesn’t quite describe the scope of Pele’s power. Many Hawaiian families trace their lineage back to Pele, meaning they count her as an ancestor.

“Pele is not just the goddess of lava. Lava is Pele,” Hoʻomanawanui told me. “The lava flows basically reaffirm what our literature tells us—that the land is alive, that Pele is alive. When we talk about the lava being alive, it’s a metaphor for the earth itself being alive. The lava is Pele, the magma is Pele, the lava flow and then when the lava hardens—each you can just replace the word with Pele.”

Even the site of the new eruption makes sense within Hawaiian culture. The current eruption has focused primarily on a subdivision called Leilani Estates. But Leilani Estates is a new name, and the subdivision sits within a larger area that Hawaiians traditionally called Keahialaka, which means “the fire of Laka.” Laka is the goddess of hula and one of Pele’s daughters.

“The Hawaiians watching are looking at the names of these places and saying, ‘Oh yeah!’” said Noelani M. Arista, a professor of Hawaiian history at the University of Hawaii. “It’s like, sometimes people are amazed that a flood will hit a flood zone. But we’ve got place names that say flood zone.”

“Anyone can come and slap a new name on any thing: ‘Let’s call it Leilani Estates!’ And Leilani is a generic name. But that won’t take away from the mana, the spiritual power and characteristics of that place, that the old place name embodies,” agreed Hoʻomanawanui.

These new names “lull people into a sense of complacency,” she said. “[They think,] I’m not actually buying property and building a house in an active lava rift zone, but I’m buying a piece of paradise.”

But sometimes these new names can be ironic. Kilauea is surrounded by rainforest, and people in Hawaii customarily link its lava flows to the Kool-Aid-red lehua flowers that grow around it. So when Hoʻomanawanui read that one of the first lava fissures in Leilani Estates opened up on Mohala Street, she laughed. “Well, of course!” she said. “Mohala means ‘to blossom,’ or ‘to bloom.’ In a way, it’s all interconnected.”

Pele’s story takes many forms—Hoʻomanawanui has studied 14 different serialized newspaper versions of it, all of which first appeared in the 19th century. But many describe a similar journey: how Pele and her family came up from an island in the South Pacific, how they found the Hawaii archipelago, and how Pele traveled to every island, looking for a place to keep her fire. She visited every island, and dug a hole in every island, until she eventually found Hawaii Island and placed her fire in Kilauea. (Hoʻomanawanui recommended that mainland Americans watch Holo Mai Pele, a PBS-filmed hula about Pele, for a credible summary of her story.)

“The story of Pele is a poetic, literary telling of what scientists would maybe call the Ring of Fire, and how volcanic activity gets to the Hawaiian islands from other parts of the Pacific,” said Hoʻomanawanui. “It’s an ideological explanation for why we don’t have volcanic activity occurring now on the other islands.”

But it’s more than a just-so story. Arista, the Hawaiian historian, contrasts how non-native Hawaii residents and native Hawaiians have discussed the recent lava flow. Much of the national media attention has focused on an American-centric understanding of the destruction, she said—for instance, by talking about the extent of property loss.

“But then you’ve got Hawaii residents saying, how amazing is the presence of this in my life,” she said. “Native people who live in the subdivision are largely saying, ‘Yes, I knew I was living in this space where volcanic activity is a huge factor, because I’ve lived my life here. And because we have this respect for Pele, I wanted to live here.’”

Hoʻomanawanui said she saw many native Hawaiians greeting the lava flow not with dread, but with acceptance. “When the flows start, you clean the house, you open the door, and you say: ‘Tūtū Pele, this is your land, take it,’” she said.

(Since Hoʻomanawanui’s family tracks its lineage back to Pele, they call her Tūtū, or grandmother. But other Hawaiians and non-Natives will call her Tūtū Pele out of respect, even if she is not an ancestor to them. “They acknowledge she’s a special force of nature—literally,” she said. Others, including non-Natives, may call her Madame Pele for the same reason.)

Hoʻomanawanui and Arista told me that seeing the lava as Pele didn’t detract from the scientific understanding of it. Instead, Pele anchors the experience of the lava, envelops it, and connects it to the lives of people who came before.

“Through dance, through costuming, through specific flowers—there’s layers of representation that I think really evoke a sensory experience beyond just knowledge, beyond just understanding as a Western scientific geological process,” Hoʻomanawanui said. “It’s a complete experience that is inclusive of that [scientific] knowledge but goes way beyond it.”

“We don’t have the words for belief or faith in this stuff,” she said. Instead, she said, Westerners should see Hawaiian customary belief as a practice and as a way of understanding the world."

"15. State of many Humboldts

In California, a county, a bay, a university, and a state park all bear the name of Alexander von Humboldt, the Prussian naturalist whose fame was once regarded as second only to Napoleon.

“Yet Humboldt,” writes Andrea Wulf, a Humboldt biographer, “is almost forgotten in the English-speaking world.”

Born to wealth in 1769, Humboldt walked away from his aristocratic life in Berlin to embark on a five-year exploration of Latin America. His goal, he wrote, was to discover “the unity of nature.” He navigated the Orinoco River and walked thousands of miles through the Andes, climbing Chimborazo along the way — regarded incorrectly at the time as the world’s tallest peak.

Everywhere Humboldt went, he took measurements. He sketched hieroglyphs, transcribed indigenous vocabularies, gauged the blueness of the sky, and collected 60,000 botanical specimens. 

Upon his return, he settled in Paris and published international best-sellers advancing the theory that all organisms were woven together in a “net-like intricate fabric.” He argued that the “insatiable avarice” of Spanish colonialists had caused incalculable harm to native cultures and stately forests.

His admirers included figures as diverse as Thomas Jefferson, Simón Bolívar, and Charles Darwin, who said that Humboldt’s writings inspired him to board the Beagle.

Over time, Humboldt’s namesakes became legion. Among them was a squid, a penguin, a glacier, an ocean current, and a lily. He never visited California. Even so, a pair of mariners exploring the north coast in 1850 named a bay after him. Humboldt County and Humboldt State Normal College, later renamed Humboldt State University, followed. 

It was on this week in 1859, that Humboldt died at the age of 89. Yet even as American newspapers eulogized him as the “most remarkable man ever born,” he soon faded in the popular imagination. 

About nine years after Humboldt’s death, the Scottish-American wanderer John Muir arrived in California, his head filled with the ideas of the great Prussian polymath. "How intensely I desire to be a Humboldt!" Muir wrote to a friend. Muir’s writings about the sanctity of the natural world later made him a giant of the environmental movement. 

According to Wulf, many of Muir’s more famous lines — along with those of Henry David Thoreau and George Perkins Marsh — were derived from their reading of Alexander von Humboldt."

Scientists Still Can't Decide How to Define a Tree - The Atlantic
"So far, there is no standout gene or set of genes that confers tree-ness, nor any particular genome feature. Complexity? Nope: Full-on, whole-genome duplication (an often-used proxy for complexity) is prevalent throughout the plant kingdom. Genome size? Nope: Both the largest and smallest plant genomes belong to herbaceous species (Paris japonica and Genlisea tuberosa, respectively—the former a showy little white-flowered herb, the latter a tiny, carnivorous thing that traps and eats protozoans).

A chat with Neale confirms that tree-ness is probably more about what genes are turned on than what genes are present. “From the perspective of the genome, they basically have all the same stuff as herbaceous plants,” he said. “Trees are big, they’re woody, they can get water from the ground to up high. But there does not seem to be some profound unique biology that distinguishes a tree from a herbaceous plant.”

Notwithstanding the difficulty in defining them, being a tree has undeniable advantages—it allows plants to exploit the upper reaches where they can soak up sunlight and disperse pollen and seeds with less interference than their ground-dwelling kin. So maybe it’s time to start thinking of tree as a verb, rather than a noun—tree-ing, or tree-ifying. It’s a strategy, a way of being, like swimming or flying, even though to our eyes it’s happening in very slow motion. Tree-ing with no finish in sight—until an ax, or a pest, or a bolt of Thanksgiving lightning strikes it down."

Birds can see Earth's magnetic fields, and we finally know how that's possible
"The mystery behind how birds navigate might finally be solved: it's not the iron in their beaks providing a magnetic compass, but a newly discovered protein in their eyes that lets them "see" Earth's magnetic fields.

These findings come courtesy of two new papers - one studying robins, the other zebra finches.

The fancy eye protein is called Cry4, and it's part of a class of proteins called cryptochromes - photoreceptors sensitive to blue light, found in both plants and animals. These proteins play a role in regulating circadian rhythms.

There's also been evidence in recent years that, in birds, the cryptochromes in their eyes are responsible for their ability to orient themselves by detecting magnetic fields, a sense called magnetoreception.

We know that birds can only sense magnetic fields if certain wavelengths of light are available - specifically, studies have shown that avian magnetoreception seems dependent on blue light.

This seems to confirm that the mechanism is a visual one, based in the cryptochromes, which may be able to detect the fields because of quantum coherence.

To find more clues on these cryptochromes, two teams of biologists set to work. Researchers from Lund University in Sweden studied zebra finches, and researchers from the Carl von Ossietzky University Oldenburg in Germany studied European robins.

The Lund team measured gene expression of three cryptochromes, Cry1, Cry2 and Cry4, in the brains, muscles and eyes of zebra finches. Their hypothesis was that the cryptochromes associated with magnetoreception should maintain constant reception over the circadian day.

They found that, as expected for circadian clock genes, Cry1 and Cry2 fluctuated daily - but Cry4 expressed at constant levels, making it the most likely candidate for magnetoreception.

This finding was supported by the robin study, which found the same thing.

"We also found that Cry1a, Cry1b, and Cry2 mRNA display robust circadian oscillation patterns, whereas Cry4 shows only a weak circadian oscillation," the researchers wrote.

But they made a couple of other interesting findings, too. The first is that Cry4 is clustered in a region of the retina that receives a lot of light - which makes sense for light-dependent magnetoreception.

The other is that European robins have increased Cry4 expression during the migratory season, compared to non-migratory chickens.

Both sets of researchers caution that more research is needed before Cry4 can be declared the protein responsible for magnetoreception.

The evidence is strong, but it's not definitive, and both Cry1 and Cry2 have also been implicated in magnetoreception, the former in garden warblers and the latter in fruit flies.

Observing birds with non-functioning Cry4 could help confirm the role it seems to play, while other studies will be needed to figure Cry1's role.

So what does a bird actually see? Well, we can't ever know what the world looks like through another species' eyes, but we can take a very strong guess.

According to researchers at the Theoretical and Computational Biophysics group at the University of Illinois at Urbana-Champaign, whose researcher Klaus Schulten first predicted magnetoreceptive cryptochromes in 1978, they could provide a magnetic field "filter" over the bird's field of view - like in the picture above.

The zebra finch study was published in the Journal of the Royal Society Interface, and the robin study was published in Current Biology."

ties and insight | sara hendren
"Jill Lepore on the writing of Rachel Carson, in the new New Yorker:
Carson’s father died in 1935, followed, two years later, by her older sister, leaving Carson to care for her mother and her nieces, ages eleven and twelve; she later adopted her grandnephew, when he was orphaned at the age of four. These obligations sometimes frustrated Carson, but not half as much as they frustrate her biographers. For [these biographers], Carson’s familial obligations—in particular, the children—are nothing but burdens that “deprived her of privacy and drained her physical and emotional energy.” They mean this generously, as a way of accounting for why Carson didn’t write more, and why, except for her Sun articles, she never once submitted a manuscript on time.

But caring for other people brings its own knowledge. Carson came to see the world as beautiful, wild, animal, and vulnerable, each part attached to every other part, not only through prodigious scientific research but also through a lifetime of caring for the very old and the very young, wiping a dying man’s brow, tucking motherless girls into bed, heating up dinners for a lonely little boy. The domestic pervades Carson’s understanding of nature. “Wildlife, it is pointed out, is dwindling because its home is being destroyed,” she wrote in 1938, “but the home of the wildlife is also our home.” If she’d had fewer ties, she would have had less insight."

Survival of the Kindest: Dacher Keltner Reveals the New Rules of Power
"When Pixar was dreaming up the idea for Inside Out, a film that would explore the roiling emotions inside the head of a young girl, they needed guidance from an expert. So they called Dacher Keltner.

Dacher is a psychologist at UC Berkeley who has dedicated his career to understanding how human emotion shapes the way we interact with the world, how we properly manage difficult or stressful situations, and ultimately, how we treat one another.

In fact, he refers to emotions as the “language of social living.” The more fluent we are in this language, the happier and more meaningful our lives can be.

We tackle a wide variety of topics in this conversation that I think you’ll really enjoy.

You’ll learn:

• The three main drivers that determine your personal happiness and life satisfaction
• Simple things you can do everyday to jumpstart the “feel good” reward center of your brain
• The principle of “jen” and how we can use “high-jen behaviors” to bootstrap our own happiness
• How to have more positive influence in our homes, at work and in our communities.
• How to teach your kids to be more kind and empathetic in an increasingly self-centered world
• What you can do to stay grounded and humble if you are in a position of power or authority
• How to catch our own biases when we’re overly critical of another’s ideas (or overconfident in our own)

And much more. We could have spent an hour discussing any one of these points alone, but there was so much I wanted to cover. I’m certain you’ll find this episode well worth your time."

Drupe - Wikipedia
"In botany, a drupe (or stone fruit) is an indehiscent fruit in which an outer fleshy part (exocarp, or skin; and mesocarp, or flesh) surrounds a single shell (the pit, stone, or pyrene) of hardened endocarp with a seed (kernel) inside.[1] These fruits usually develop from a single carpel, and mostly from flowers with superior ovaries[1] (polypyrenous drupes are exceptions). The definitive characteristic of a drupe is that the hard, "lignified" stone (or pit) is derived from the ovary wall of the flower—in an aggregate fruit composed of small, individual drupes (such as a raspberry), each individual is termed a drupelet and may together form a botanic berry.

Other fleshy fruits may have a stony enclosure that comes from the seed coat surrounding the seed, but such fruits are not drupes.

Some flowering plants that produce drupes are coffee, jujube, mango, olive, most palms (including date, sabal, coconut and oil palms), pistachio, white sapote, cashew, and all members of the genus Prunus, including the almond (in which the mesocarp is somewhat leathery), apricot, cherry, damson, nectarine, peach, and plum.

The term drupaceous is applied to a fruit which has the structure and texture of a drupe,[2] but which does not precisely fit the definition of a drupe."

Wrong - By David H. Freedman - The New York Times
"Putting trust in experts who are probably wrong is only part of the problem. The other side of the coin is that many people have all but given up on getting good advice from experts. The total effect of all the contradicting and shifting pronouncements is to make expert conclusions at times sound like so much blather — a background noise of modern life. I think by now most of us have at some point caught ourselves thinking, or at least have heard from people around us, something along these lines: Experts! One day they say vitamin X / coffee / wine / drug Y / a big mortgage / baby learning videos / Six Sigma / multitasking / clean homes / arguing / investment Z is a good thing, and the next they say it’s a bad thing. Why bother paying attention? I might as well just do what I feel like doing. Do we really want to just give up on expertise in this way? Even if experts usually fail to give us the clear, reliable guidance we need, there are still situations, as we’ll see, where failing to follow their advice can be self-defeating and even deadly.

So I’m not going to spend much time trying to convince you that experts are often, and possibly usually, wrong. Instead, this book is about why expertise goes wrong and how we may be able to do a better job of seeking out more trustworthy expert advice. To that end, we’re going to look at how experts — including scientists, business gurus, and our other highly trusted sources of wisdom — fall prey to a range of measurement errors, how they come to have deep biases that lead them into gamesmanship and even outright dishonesty, and how interactions among them tend to worsen rather than correct for these problems. We’re also going to examine the ways in which the media sort through the flow of dubious expert pronouncements and further distort them, as well as how we ourselves are drawn to the worst of this shoddy output, and how we end up being even more misled on the Internet. Finally, we’ll try to extract from everything we’ve discovered a set of rough guidelines that can help to separate the most suspect expert advice from the stuff that has a better chance of holding up.

As I said, most people are quite comfortable with the notion that there’s a real problem with experts. But some — mostly experts — do in fact take objection to that claim. Here are the three objections I encountered the most often, along with quick responses.

(1) If experts are so wrong, why are we so much better off now than we were fifty or a hundred years ago? One distinguished professor put it to me this way in an e-mail note: “Our life expectancy has almost doubled in the past seventy-five years, and that’s because of experts.” Actually, the vast majority of that gain came earlier in the twentieth century from a very few sharp improvements, and especially from the antismoking movement. As for all of the drugs, diagnostic tools, surgical techniques, medical devices, lists of foods to eat and avoid, and impressive breakthrough procedures and technologies that fill medical journals and trickle down into media reports, consider this: between 1978 and 2001, according to one highly regarded study, U.S. life spans increased fewer than three years on average — when the drop in smoking rates slowed around 1990, so did life-expectancy gains. It’s hard to claim we’re floating on an ocean of marvelously effective advice from a range of experts when we’ve been skirting the edges of a new depression, the divorce rate is around 50 percent, energy prices occasionally skyrocket, obesity rates are climbing, children’s test scores are declining, we’re forced to worry about terrorist and even nuclear attacks, 118 million prescriptions for antidepressants are written annually in the United States, chunks of our food supply periodically become tainted, and, well, you get the idea. Perhaps a reasonable model for expert advice is one I might call “punctuated wrongness” — that is, experts usually mislead us, but every once in a while they come up with truly helpful advice.

(2) Sure, experts have been mostly wrong in the past, but now they’re on top of things. In mid-2008 experts were standing in line to talk about the extensive, foolproof controls protecting our banks and other financial institutions that weren’t in place in the late 1920s — just before those institutions started collapsing. Cancer experts shake their heads today over the ways in which generations of predecessors wasted decades hunting down the mythical environmental or viral roots of most cancers, before pronouncing as a sure thing the more recent theory of how cancer is caused by mutations in a small number of genes — a theory that, as we’ll see, has yielded almost no benefits to patients after two decades. Most everyone missed what was happening to our climate, or even spoke of a global cooling crisis, until we came to today’s absolutely certain understanding of global warming and its man-made causes — well, we’ll see how that turns out. How could we have been so foolish before? And what sort of fool would question today’s experts’ beliefs? In any case, the claim that we’ve come from wrong ideas to right ideas suggests that there’s a consensus of experts today on what the right ideas are. But there is often nothing close to such a consensus. When experts’ beliefs clash, somebody has to be wrong — hardly a sign of an imminent convergence on truth.

And, finally, (3) So what if experts are usually wrong? That’s the nature of expert knowledge — it progresses slowly as it feels its way through difficult questions. Well, sure, we live in a complex world without easy answers, so we might well expect to see our experts make plenty of missteps as they steadily chip away at the truth. I’m not saying that experts don’t make any progress, or that they ought to have figured it all out long ago. I’m suggesting three things: we ought to be fully aware of how large a percentage of expert advice is flawed; we should find out if there are perhaps much more disconcerting reasons why experts so frequently get off track other than “that’s just the nature of the beast”; and we ought to take the trouble to see if we can come up with clues that will help distinguish better expert advice from fishier stuff. And, by the way, if experts are so comfortable with the notion that their efforts ought to be expected to spit out mostly wrong answers, why don’t they work a little harder to get this useful piece of information across to us when they’re interviewed on morning news shows or in newspaper articles, and not just when they’re confronted with their errors?

Given that I’ve already started throwing the term “expert” around left and right, I suppose I ought to make sure you know what I mean by the word. Academics study “expertise” in pianists, athletes, burglars, birds, infants, computers, trial witnesses, and captains of industry, to name just a few examples. But when I say “expert,” I’m mostly thinking of someone whom the mass media might quote as a credible authority on some topic — the sorts of people we’re usually referring to when we say things like “According to experts . . .” These are what I would call “mass” or “public” experts, people in a position to render opinions or findings that a large number of us might hear about and choose to take into account in making decisions that could affect our lives. Scientists are an especially important example, but I’m also interested in, for example, business, parenting, and sports experts who gain some public recognition for their experience and insight. I’ll also have some things to say about pop gurus, celebrity advice givers, and media pundits, as well as about what I call “local” experts — everyday practitioners such as non-research-oriented doctors, stockbrokers, and auto mechanics.

I’ve heard it said, half kiddingly, that meteorologists are the only people who get paid to be wrong. I would argue that in that sense most of our experts are paid to be wrong, and are probably wrong a much higher percentage of the time than are meteorologists. I’m going to show that although the process of wringing useful insights and advice from complex subjects may indeed be an inherently slow and erratic one, there are many other, less benign reasons why experts go astray. In fact, we’ll see that expert pronouncements are pushed toward wrongness so strongly that in the end it’s harder, I think, to explain why they’re sometimes right. But that doesn’t mean we’re hopelessly mired in this swamp of bad advice. With a decent compass, we can find our way out. Let’s start by exploring some of the muck."

When Scientists "Discover" What Indigenous People Have Known For Centuries | Science | Smithsonian
"Our knowledge of what animals do when humans aren’t around has steadily increased over the last 50 years. For example, we know now that animals use tools in their daily lives. Chimps use twigs to fish for termites; sea otters break open shellfish on rocks they selected; octopi carry coconut shell halves to later use as shelters. But the latest discovery has taken this assessment to new heights—literally.

A team of researchers led by Mark Bonta and Robert Gosford in northern Australia has documented kites and falcons, colloquially termed “firehawks,” intentionally carrying burning sticks to spread fire. While it has long been known that birds will take advantage of natural fires that cause insects, rodents and reptiles to flee and thus increase feeding opportunities, that they would intercede to spread fire to unburned locales is astounding.

It’s thus no surprise that this study has attracted great attention as it adds intentionality and planning to the repertoire of non-human use of tools. Previous accounts of avian use of fire have been dismissed or at least viewed with some skepticism.

But while new to Western science, the behaviors of the nighthawks have long been known to the Alawa, MalakMalak, Jawoyn and other Indigenous peoples of northern Australia whose ancestors occupied their lands for tens of thousands of years. Unlike most scientific studies, Bonta and Gosford’s team foregrounded their research in traditional Indigenous ecological knowledge. They also note that local awareness of the behavior of the firehawks is ingrained within some of their ceremonial practices, beliefs and creation accounts.

The worldwide attention given to the firehawks article provides an opportunity to explore the double standard that exists concerning the acceptance of Traditional Knowledge by practitioners of Western science.

Traditional Knowledge ranges from medicinal properties of plants and insights into the value of biological diversity to caribou migration patterns and the effects of intentional burning of the landscape to manage particular resources. Today, it’s become a highly valued source of information for archaeologists, ecologists, biologists, ethnobotanists, climatologists and others. For example, some climatology studies have incorporated Qaujimajatuqangit (Inuit traditional knowledge) to explain changes in sea ice conditions observed over many generations.

Yet despite the wide acknowledgement of their demonstrated value, many scientists continue to have had an uneasy alliance with Traditional Knowledge and Indigenous oral histories.

On the one hand, these types of knowledge are valued when they support or supplements archaeological, or other scientific evidence. But when the situation is reversed—when Traditional Knowledge is seen to challenge scientific “truths —then its utility is questioned or dismissed as myth. Science is promoted as objective, quantifiable, and the foundation for “real” knowledge creation or evaluation while Traditional Knowledge may be seen as anecdotal, imprecise and unfamiliar in form.

Are Indigenous and Western systems of knowledge categorically antithetical? Or do they offer multiple points of entry into knowledge of the world, past and present?

Ways of Knowing

There are many cases where science and history are catching up with what Indigenous peoples have long known.

For instance, in the past two decades, archaeologists and environmental scientists working in coastal British Columbia have come to recognize evidence of mariculture—the intentional management of marine resources—that pre-dates European settlement. Over the course of thousands of years, the ancestors of the Kwakwaka’wakw and other Indigenous groups there created and maintained what have become known as “clam gardens”—rock-walled, terrace-like constructions that provide ideal habit for butter clams and other edible shellfish.

To the Kwakwaka’wakw, these were known as loxiwey, according to Clan Chief Adam Dick (Kwaxsistalla) who has shared this term and his knowledge of the practice with researchers. As marine ecologist Amy Groesbeck and colleagues have demonstrated, these structures increase shellfish productivity and resource security significantly. This resource management strategy reflects a sophisticated body of ecological understanding and practice that predates modern management systems by millennia.

These published research studies now prove that Indigenous communities knew about mariculture for generations—but Western scientists never asked them about it before. Once tangible remains were detected, it was clear mariculture management was in use for thousands of years. There is a move underway by various Indigenous communities in the region to restore and recreate clam gardens and put them back into use.

A second example demonstrates how Indigenous oral histories correct inaccurate or incomplete historical accounts. There are significant differences between Lakota and Cheyenne accounts of what transpired at the Battle of Greasy Grass (Little Big Horn) in 1876, and the historical accounts that appeared soon after the battle by white commentators.

The Lakota and Cheyenne can be considered more objective than white accounts of the battle that are tainted by Eurocentric bias. The ledger drawings of Red Horse, a Minneconjou Sioux participant in the battle, record precise details such as trooper’s uniforms, the location of wounds on horses, and the distribution of Indian and white casualties.

In 1984, a fire at the battleground revealed military artifacts and human remains that prompted archaeological excavations. What this work revealed was a new, more accurate history of the battle that validated many elements of the Native American oral histories and accompanying pictographs and drawings of the events. However, without the archaeological evidence, many historians gave limited credence to the accounts obtained from the participating Native American warriors.

Hypotheses incorporating traditional knowledge-based information can lead the way toward unanticipated insights. The travels of Glooscap, a major figure in Abenaki oral history and worldview, are found throughout the Mi’kmaw homeland of the Maritime provinces of eastern Canada. As a Transformer, Glooscap created many landscape features. Anthropologist Trudy Sable (Saint Mary’s University) has noted a significant degree of correlation between places named in Mi’kmaw legends and oral histories and recorded archaeological sites.

Opportunities at the Intersection

As ways of knowing, Western and Indigenous Knowledge share several important and fundamental attributes. Both are constantly verified through repetition and verification, inference and prediction, empirical observations and recognition of pattern events.

While some actions leave no physical evidence (e.g. clam cultivation), and some experiments can’t be replicated (e.g. cold fusion), in the case of Indigenous knowledge, the absence of “empirical evidence” can be damning in terms of wider acceptance.

Some types of Indigenous knowledge, however, simply fall outside the realm of prior Western understanding. In contrast to Western knowledge, which tends to be text-based, reductionist, hierarchical and dependent on categorization (putting things into categories), Indigenous science does not strive for a universal set of explanations but is particularistic in orientation and often contextual. This can be a boon to Western science: hypotheses incorporating traditional knowledge-based information can lead the way toward unanticipated insights.

There are partnerships developing worldwide with Indigenous knowledge holders and Western scientists working together. This includes Traditional Ecological Knowledge informing government policies on resource management in some instances. But it is nonetheless problematic when their knowledge, which has been dismissed for so long by so many, becomes a valuable data set or used selectively by academics and others.

To return to the firehawks example, one way to look at this is that the scientists confirmed what the Indigenous peoples have long known about the birds’ use of fire. Or we can say that the Western scientists finally caught up with Traditional Knowledge after several thousand years."

Una mutación social acecha a la humanidad
"las transformaciones del trabajo y de la subjetividad provocadas por la globalización y la financiarización de la economía: la desterritorialización, la precarización del empleo, el declive de la burguesía y el proletariado y su paulatina reemplazo por el “cognitariado” y la clase ejecutiva financiera, el sometimiento de los trabajadores por dispositivos de automatización y control, cuyos efectos incluyen la dificultad para crear formas de solidaridad y de relación cuerpo a cuerpo."



"Me interesa en particular la separación entre el ingeniero y el poeta, entre el conocimiento científico y la imaginación artística, que es una consecuencia de la reducción de la formación, la educación y el sistema escolar y universitario a meras herramientas para la acumulación financiera. El declive de la enseñanza humanística, la introducción de criterios puramente económicos en el pensamiento científico y en la innovación tecnológica son los efectos más evidentes y peligrosos de la sumisión del conocimiento al provecho económico. En este contexto, la figura del economista domina abusivamente el panorama cognitivo. ¿Qué es la economía? ¿Una ciencia? No me parece. La ciencia se define ante todo por su objeto, por la capacidad de formular leyes universales que nos permiten prever los acontecimientos futuros. La economía no tiene un objeto independiente de su actuación, y por ende me parece una técnica, no una ciencia. El problema es que esta técnica pretende reglar las otras formas de conocimiento según un principio que no pertenece a la ciencia, sino al interés de una minoría. La reducción de la dinámica social al provecho económico devino el dogma central del pensamiento contemporáneo: no se puede decir, pensar ni investigar nada si no sirve a la acumulación de capital."

Exploding Chocolate Teacakes - Gastro Obscura
"In the 1960s, Royal Air Force pilots made a startling discovery about their sweets."



"When Tony Cunnane joined the Royal Air Force in 1953, chocolate teacakes were “all the rage.” Employees aboard strategic nuclear strike aircrafts requested the snack be added to their in-flight ration boxes. But this wasn’t just a sugary jolt to fuel their Cold War training. Chocolate-coated marshmallow teacakes had become, as Cunnane described it, “the subject of some rather unscientific in-flight experiments.”

Shortly after the foil-wrapped treats appeared in RAF ration packs, pilots began to notice that as altitude increased, the teacakes expanded. At 15,000 feet, the marshmallow interior cracked the chocolate shell. Air crews removed the teacakes from their silver foil packaging and perched them around the cabin for observation. The aerated marshmallow continued to swell as pressure changed, and the sweets became too big to eat in one bite. Many noted that, despite the extreme physical effects, the expansion didn’t compromise the taste.

But the expanding teacakes’ fame was short-lived. After a period of marshmallow fever aboard the V-Bombers departing from Gaydon air base, an explosion put a stop to the fun. During the summer of 1965, a captain and student pilot forgot they had placed unwrapped teacakes above their instrument panels. When the captain pulled an emergency depressurizing switch during a training mission, the treats erupted. Shards of chocolate and marshmallow hit the windshield, flight controls, and the mens’ uniforms.

Shortly thereafter, the RAF put marshmallows on their no-fly list. Decades later, The Telegraph recounted the incident with an article entitled “Deadly Teacakes.” Thankfully, no lives were lost in the explosion.

Need to Know
While it's never been confirmed, it's likely the pilots' chocolate teacakes were Tunnock's, a still-popular brand in the United Kingdom. Under normal circumstances, they won't explode."

HEWN, No. 250
"I wrote a book review this week of Brian Dear’s The Friendly Orange Glow: The Untold History of of PLATO System and the Dawn of Cyberculture. My review’s a rumination on how powerful the mythologizing is around tech, around a certain version of the history of technology – “the Silicon Valley narrative,” as I’ve called this elsewhere – so much so that we can hardly imagine that there are other stories to tell, other technologies to build, other practices to adopt, other ways of being, and so on.

I was working on the book review when I heard the news Tuesday evening that the great author Ursula K. Le Guin had passed away, I immediately thought of her essay “The Carrier Bag Theory of Fiction” – her thoughts on storytelling about spears and storytelling about bags and what we might glean from a culture (and a genre) that praises the former and denigrates the latter.
If science fiction is the mythology of modern technology, then its myth is tragic. “Technology,” or “modern science” (using the words as they are usually used, in an unexamined shorthand standing for the “hard” sciences and high technology founded upon continuous economic growth), is a heroic undertaking, Herculean, Promethean, conceived as triumph, hence ultimately as tragedy. The fiction embodying this myth will be, and has been, triumphant (Man conquers earth, space, aliens, death, the future, etc.) and tragic (apocalypse, holocaust, then or now).

If, however, one avoids the linear, progressive, Time’s-(killing)-arrow mode of the Techno-Heroic, and redefines technology and science as primarily cultural carrier bag rather than weapon of domination, one pleasant side effect is that science fiction can be seen as a far less rigid, narrow field, not necessarily Promethean or apocalyptic at all, and in fact less a mythological genre than a realistic one.


The problems of technology – and the problems of the storytelling about the computing industry today, which seems to regularly turn to the worst science fiction for inspiration – is bound up in all this. There’s a strong desire to create, crown, and laud the Hero – a tendency that’s going to end pretty badly if we don’t start thinking about care and community (and carrier bags) and dial back this wretched fascination with weapons, destruction, and disruption.

(Something like this, I wonder: “The Ones Who Walk Away From Omelas” by Ursula K. Le Guin.)

Elsewhere in the history of the future of technology: “Sorry, Alexa Is Not a Feminist,” says Ian Bogost. “The People Who Would Survive Nuclear War” by Alexis Madrigal.

There are many reasons to adore Ursula K. Le Guin. And there are many pieces of her writing, of course, one could point to and insist “you must read this. You must.” For me, the attraction was her grounding in cultural anthropology – I met Le Guin at a California Folklore Society almost 20 years ago when I was a graduate student in Folklore Studies – alongside her willingness to challenge the racism and imperialism and expropriation that the field engendered. It was her fierce criticism of capitalism and her commitment to freedom. I’m willing to fight anyone who tries to insist that Sometimes a Great Notion is the great novel of the Pacific Northwest. Really, you should pick almost any Le Guin novel in its stead – Always Coming Home, perhaps. Or The Word for the World is Forest. She was the most important anarchist of our era, I posted on Facebook when I shared the NYT obituary. It was a jab at another Oregon writer who I bet thinks that’s him. But like Kesey, his notion is all wrong.

Fewer Heroes. Better stories about people. Better worlds for people.

Yours in struggle,
~Audrey"

Reasons To Be Cheerful
"I’m starting an online project here that is an continuation and extension of some writing and talks I’ve done recently.

The project will be cross-platform—some elements may appear on social media, some on a website and some might manifest as a recording or performance… much of the published material will be collected here.

What is Reasons To Be Cheerful?

I imagine, like a lot of you who look back over the past year, it seems like the world is going to Hell. I wake up in the morning, look at the paper, and go, "Oh no!" Often I’m depressed for half the day. It doesn’t matter how you voted on Brexit, the French elections or the U.S. election—many of us of all persuasions and party affiliations feel remarkably similar.

As a kind of remedy and possibly as a kind of therapy, I started collecting good news that reminded me, "Hey, there's actually some positive stuff going on!" Almost all of these initiatives are local, they come from cities or small regions who have taken it upon themselves to try something that might offer a better alternative than what exits. Hope is often local. Change begins in communities.

I will post thoughts, images and audio relating to this initiative on whichever platform seems suitable and I’ll welcome contributions from others, if they follow the guidelines I’ve set for myself.

These bits of good news tend to fall into a few categories:

Education
Health
Civic Engagement
Science/Tech
Urban/Transportation
Energy
Culture

Culture, music and the arts might include, optimistically, some of my own work and projects, but just as much I hope to promote the work of others that has a proven track record.

Why do I do this? Why take the time? Therapy, I guess, though once in awhile I meet someone who has the connections and skills but might not be aware of some of these initiatives and innovations, so I can pass the information on. I sense that not all of this is widely known.

Emulation of successful models- 4 guidelines

I laid out 4 guidelines as I collected these examples:

1. Most of the good stuff is local. It’s more bottom up, community and individually driven. There are exceptions.

2. Many examples come from all over the world, but despite the geographical and cultural distances in many cases others can adopt these ideas—these initiatives can be utilized by cultures other than where they originated.

3. Very important. All of these examples have been tried and proven to be successful. These are not merely good IDEAS; they’ve been put into practice and have produced results.

4. The examples are not one-off, isolated or human interest, feel-good stories. They’re not stories of one amazing teacher, doctor, musician or activist- they’re about initiatives that can be copied and scaled up.

If it works, copy it

For example, in an area I know something about, there was an innovative bike program in Bogota, and years later, I saw that program become a model for New York and for other places.

How Birds-of-Paradise Produce Super-Black Feathers - The Atlantic
"Blackbirds, it turns out, aren’t actually all that black. Their feathers absorb most of the visible light that hits them, but still reflect between 3 and 5 percent of it. For really black plumage, you need to travel to Papua New Guinea and track down the birds-of-paradise.

Although these birds are best known for their gaudy, kaleidoscopic colors, some species also have profoundly black feathers. The feathers ruthlessly swallow light and, with it, all hints of edge or contour. They make body parts seem less like parts of an actual animal and more like gaping voids in reality. They’re blacker than black. None more black.

By analyzing museum specimens, Dakota McCoy, from Harvard University, has discovered exactly how the birds achieve such deep blacks. It’s all in their feathers’ microscopic structure.

A typical bird feather has a central shaft called a rachis. Thin branches, or barbs, sprout from the rachis, and even thinner branches—barbules—sprout from the barbs. The whole arrangement is flat, with the rachis, barbs, and barbules all lying on the same plane. The super-black feathers of birds-of-paradise, meanwhile, look very different. Their barbules, instead of lying flat, curve upward. And instead of being smooth cylinders, they are studded in minuscule spikes. “It’s hard to describe,” says McCoy. “It’s like a little bottlebrush or a piece of coral.”

These unique structures excel at capturing light. When light hits a normal feather, it finds a series of horizontal surfaces, and can easily bounce off. But when light hits a super-black feather, it finds a tangled mess of mostly vertical surfaces. Instead of being reflected away, it bounces repeatedly between the barbules and their spikes. With each bounce, a little more of it gets absorbed. Light loses itself within the feathers.

McCoy and her colleagues, including Teresa Feo from the National Museum of Natural History, showed that this light-trapping nanotechnology can absorb up to 99.95 percent of incoming light. That’s between 10 and 100 times better than the feathers of most other black birds, like crows or blackbirds. It’s also only just short of the blackest materials that humans have designed. Vantablack, an eerily black substance produced by the British company Surrey Nanosystems, can absorb 99.965 percent of incoming light. It consists of a forest of vertical carbon nanotubes that are “grown” at more than 750 degrees Fahrenheit. The birds-of-paradise mass-produce similar forests, using only biological materials, at body temperature.

Vantablack is genuinely amazing: It’s so good at absorbing light that if you move a laser onto it, the red dot disappears. But McCoy has created a similar demonstration with her super-black feathers. In the image below, you can see two feathers, both of which have been sprinkled with gold dust. The left one is from the lesser melampitta—a bird of average blackness—and it looks as golden as its surroundings. The right one comes from a paradise riflebird—one of the 42 species of bird-of-paradise. Yes, it is covered in gold dust. And yes, it still looks black. The gold settles within the grooves of microscopic forest, and all of its glitter is lost.

This opens up several other questions, says Rafael Maia from Columbia University, who studies the evolution of bird colors. “Is this something unique to birds-of-paradise, or have other species evolved similar optical solutions?” he says. “If they have, do they use the same type of feather modifications?”

Many animals and plants use microscopic structures to produce exceptionally vivid colors with metallic sheens; this is called iridescence. Comparably fewer species use microscopic structures for the opposite purpose: to absorb colors entirely. These include a few butterflies and the Gaboon viper.

The viper—whose fangs, at two inches, are the longest of any snake—likely uses its super-black scales for camouflage, breaking up its outline so that the rest of its body better blends into the leaf litter of a rainforest. The birds-of-paradise, meanwhile, probably use their unfeasibly black blacks for the same thing that seems to motivate everything about them: sex.

“These likely evolved as an optical illusion, to make adjacent colors seem even brighter than they are,” says McCoy. “Animal eyes and brains are wired to control for the amount of ambient light. That’s why an apple looks red whether it is in the sun or the shade, even though the wavelength hitting our eyes is quite different in those scenarios. A super-black frame inhibits this ability, so nearby colors look like they are very bright—even glowing.”

The male birds use this illusion to great effect. The magnificent riflebird—that’s its adjective, not mine—splays out his super-black wings and flicks his head between them, showing off his electric blue throat. The superb bird-of-paradise—again, that is literally its name—spreads a cape of super-black feathers to highlight the electric blue patches on his cheeks and chest. He ends up looking like a spectral, wide-mouthed face. The six-plumed bird-of-paradise erects a super-black tutu and shimmies about to show off his kaleidoscopic throat bib.

Feathers on birds-of-paradise contain light-trapping nanotechnology that makes some of the deepest blacks in the world.

The illusions work best when viewed straight on. From that angle, the little barbules and spikes are pointing straight at you, and they become better at trapping light. When viewed from the side, the super-blacks lose some of their blackness. That’s why the dancing males take such care to face the objects of their attention, bouncing around so their audience never gets a side view.

Super-black surfaces have plenty of uses for humans, too. They could camouflage military vehicles, help solar panels collect more light, or stop stray light from entering telescopes, improving the ability to spot faint stars. Vantablack can already do all of the above, but McCoy thinks the structure in super-black feathers might still be useful to engineers. “If these could be really cheaply 3-D printed, that would be amazing,” she says."

Duskin Drum » School of advanced studies
"BIO:
At the School of Advanced Studies, duskin drum is a founding professor and researcher in the Material Relations research group. He is an interdisciplinary scholar, artist, performer, and woodsman. In 2017, he completed a doctorate in Performance Studies with designated emphases in Native American Studies, and Science and Technology Studies at University of California, Davis. In 2005, he earned a Bachelors of Arts studying interdisciplinary theatre and performance at Evergreen State College . For 15 years, duskin has been making art and performance in Asia, Europe and the Americas.

RESEARCH INTERESTS:
The Material Relations research group is an interdisciplinary collaboration devising a new theory of love for studying ecologically substantiating human-nonhuman relations including technological relations. duskin is particular interested in nonhumans loving humans, or where people understand and feel themselves to be loved by non-human entities or materials. How does accepting speculation of universal sentience and vitality of nonhumans change the study of material relations?

From his dissertation study of petroleum performances and professional art career, Duskin brings a broad theoretical engagement with material relations at the intersections of indigenous studies, social cultural anthropology, science and technology studies, and ecological art production.

Duskin is considering practices of love in substantive more-than-human human relationships such as petroleum, salmon, and server farms. He also wants to critique how love figures scientific research and language. He is deeply interested ethical and deontic regulations enacted by material entanglements with substantiating nonhuman and more-than-human arrangements.

Duskin’s interests in both the petroleum complex and indigenous legal systems emerge from analyzing and speculating about human-nonhuman ecological relations.

Duskin researches using methods from art practices, cultural anthropology, science and technology studies, ecological criticism, and indigenous studies. Duskin has been developing an innovative performance method. He devises participatory performances that submerge the participants in the crucial questions of his research.

He is also interested in comparative studies of knowledge production by contributing methods like creative practice-as-research, innovations from theatre and performance, and indigenous knowledge practices.

Duskin is also interested in anime, manga and other graphic storytelling.

Additional information is available at duskin’s academia.edu page and his personal website.

TEACHING INTERESTS AND APPROACHES
Duskin’s educational background is interdisciplinary, seminar-style and project-driven learning. Even in large lecture classes, he break students into small groups for discussion and activities. He combines reading, writing and experiential learning using techniques from digital media, theatre, performance, and participatory art. Somatic exercises, improvisations, meditation, collaborative writing exercises and performances expose students to and activate different modes of attention and learning.

In his electives, Duskin supports students making final projects in mediums other than the textual essay or report. He encourages students to produce all kinds of media or performance projects instead of traditional essays, and teaches them to develop critical skills appropriate to each medium. In these kinds of practices-as-research projects students keep a reflective production journal that is submitted along with their project, and write a short critical essay reflecting on their creative processes and outcomes of their project. Self-reflection is practical and theoretical. Reflection about personal work becomes a means by which critical ideas, frameworks and interpretations can move from creative practice into other skills and work/study situations."

Recurrent Domestication by Lepidoptera of Genes from Their Parasites Mediated by Bracoviruses
"Laila Gasmi, Helene Boulain, Jeremy Gauthier, Aurelie Hua-Van, Karine Musset, Agata K. Jakubowska, Jean-Marc Aury, Anne-Nathalie Volkoff, Elisabeth Huguet, Salvador Herrero , Jean-Michel Drezen"



"Bracoviruses are symbiotic viruses associated with tens of thousands of species of parasitic wasps that develop within the body of lepidopteran hosts and that collectively parasitize caterpillars of virtually every lepidopteran species. Viral particles are produced in the wasp ovaries and injected into host larvae with the wasp eggs. Once in the host body, the viral DNA circles enclosed in the particles integrate into lepidopteran host cell DNA. Here we show that bracovirus DNA sequences have been inserted repeatedly into lepidopteran genomes, indicating this viral DNA can also enter germline cells. The original mode of Horizontal Gene Transfer (HGT) unveiled here is based on the integrative properties of an endogenous virus that has evolved as a gene transfer agent within parasitic wasp genomes for ≈100 million years. Among the bracovirus genes thus transferred, a phylogenetic analysis indicated that those encoding C-type-lectins most likely originated from the wasp gene set, showing that a bracovirus-mediated gene flux exists between the 2 insect orders Hymenoptera and Lepidoptera. Furthermore, the acquisition of bracovirus sequences that can be expressed by Lepidoptera has resulted in the domestication of several genes that could result in adaptive advantages for the host. Indeed, functional analyses suggest that two of the acquired genes could have a protective role against a common pathogen in the field, baculovirus. From these results, we hypothesize that bracovirus-mediated HGT has played an important role in the evolutionary arms race between Lepidoptera and their pathogens."

2017 Civilisation has been corrupted, would you like to open a new file?
"Moving Forward.

Moving forward in the 21st century requires us to systematically de-corrupt civilisation.

1. We need to collectively buy out legacy interests, dependancies, and blocks – like we did with slavery in the UK to allow us to all move forward, we will need to buy out and systemically make redundant our carbon economy.

2. We need to work to bridge the gap between the sense of justice and the law and reinventing regulation & Goverance to match.

3. We need a new governance model which acknowledges our global interdependence at all scales & focuses on the quality, diversity and integrity Of feedback in all its natures – & recognises the future of Goverance is realtime, contingent and contextual – for more see – Innovation Needs a Boring Revolution [https://provocations.darkmatterlabs.org/innovation-needs-a-boring-revolution-741f884aab5f ]

4. We need to invest in a restorative justice national programme to acknowledge and respect the economic, social, gender and cultural violence many in our society have been faced.

5. We need to out forward a Grand Jubilee not of debt by transgression focused on establishing a fresh start with new ground rules and new social contract. Inviting us all into this new world.

6. We need to put Homo Cívica as the centre of our world as opposed to Homo Economicus – further explored here – Towards a Homo Civica Future [https://provocations.darkmatterlabs.org/its-time-to-rediscover-homo-c%C3%ADvica-bef94da3e16f ]

7. Structurally, this transition needs us recognise the progress in science of being human & the reality of a social injustice 2.0 – as outlined more fully here – Human(e) Revolution [https://provocations.darkmatterlabs.org/the-human-e-revolution-267022d76c71 ]

8. We need us to democratise agency, care, creativity and innovation – as outlined here – Beyond Labour [https://provocations.darkmatterlabs.org/beyond-labour-96b23417dea3 ]

9. Detox our emotional addition to a mal-consumer economy driven by Bad Work. Further explored here – The Case for Good Work [https://provocations.darkmatterlabs.org/there-is-nothing-wrong-with-the-consumer-society-as-an-idea-3c408b17ce ]

10. We need to embrace Moonshots and System Change – to misquote Cooper from Interstellar – “help us find our place in the stars as opposed to fighting for our place in the dirt.” Further explored here – Moonshots & System Change. [https://provocations.darkmatterlabs.org/moonshots-system-change-368c12e2e2ab ]

11. We need to break the duopoly of Market and State – rebuilding the role of Learned Societies, as decentralised agents for advancing the public good – driven by the legitimacy of knowledge, to compliment the legitimacy of the vote and the consumer. Further explored here – Remaking Professionalism. [https://provocations.darkmatterlabs.org/beyond-the-good-words-2d034fd82942 ]

12. We need to re-embrace freedom – a democracy of freedom. A freedom not just “to do”, but a freedom for all, where we nurture the conditions for all to be free, all to be intrinsically motivated, organised and purposeful. There can be no coercive pathway to a 21st Century. Further explored here – Democracy of Purpose [https://provocations.darkmatterlabs.org/purposeful-democracy-9d9966655d63 ]

But perhaps, most critically of all, what this reboot requires is for all these programmes, activities and investments to be made together, simultaneously, and openly – a systematic reboot of our civilisation. This future cannot be crawled away from – it must be audaciously fought. It requires audacity, and a belief in a radically better tomorrow. A belief in our humanity, not a grudging nod to diversity – but our complete full on belief in humanity as a whole. This is a tomorrow which needs the future to not be a zero sum game but a world of great abundance. Let us reignite our democracy of dreams and fuel the audacity that is the antidote to fear and our zombie society.

I would put forward any viable new government wishing to take us into the real 21st century as opposed to sustain us in a zombie 20th century, must systemically de-corrupt society. If we are to rebuild a new inclusive economy, we must rebuild trust in ourselves – personally and also collectively – without this there can be no progress."

“My Working Will be the Work:” Maintenance Art and Technologies of Change – The New Inquiry
"In 1973, Mierle Laderman Ukeles staged a series of art performances at the Wadsworth Atheneum in Connecticut. In Transfer: The Maintenance of the Art Object, she took over the duties of the museum’s janitor and used his tools to clean a glass case containing a mummy. When she was finished, she stamped her cleaning tools and the mummy case with a rubber stamp, branding them “Maintenance Art Works.” She then transferred the cleaning duties to the museum’s curator, who alone was allowed to handle and conserve artworks. In another performance, Keeper of the Keys, Ukeles took the janitor’s keys and locked and unlocked various offices and rooms in the museum. Once Ukeles had locked an office, it became a Maintenance Artwork and no one was permitted to enter or use the room. Keeper of the Keys created an uproar, as it drastically impacted the work lives of the museum’s staff who pleaded to have certain floors exempted from the project so they could work undisturbed. Ukeles’ performances, examples of conceptual art called “Institutional Critique,” surfaced the hidden labor of maintenance in the museum setting, and the subsequent visibility of this labor proved to be incredibly disruptive to the institution of the museum.

Recently within the history of science and technology, scholars have focused an increasing amount of attention on the maintenance of technology and systems. Maintenance has been long overlooked in favor of a focus on innovation and design practices; the very beginnings of technology have always been more appealing than their often messy or disappointing longer lives. One important aspect of this “turn” to maintenance histories is that the un-and-underpaid labor of women and marginalized people, who are disproportionately relegated to maintenance work, has again become an important site for articulating the history of technology. A similar turn was initiated by scholars, like historian of technology Ruth Schwartz Cowan and others, in the 1980s.

Even before these early efforts, however, art historian and curator Helen Molesworth has argued that women artists, like Ukles and Martha Rosler, were making significant contributions to a discourse about public and private life, and the hidden labor that sustains both. Ukeles and Rosler, despite often being marginalized as “feminist artists,” were in the 1970s making strikingly political art about labor and gender, about technology and potential violence, and about the ability of art itself to sustain and renew utopia and revolution.

In her video piece The Semiotics of the Kitchen (1975), Rosler appears behind a table laden with kitchen tools, with the refrigerator, sink, and cupboards of her kitchen as backdrop. The artist works through her collection of kitchen gadgets one by one, alphabetically: A is for apron, K is for knife. But her gestures clash with the setting. Instead of using the knife to mime cutting food, she stabs violently at the air. She ladles invisible soup, but then flings it over her shoulder. Rosler’s deadpan stare and her gestural subversion of the audiences cooking-show set-up expectations make a mockery, or perhaps even a threat, out of the labor of the kitchen. Her misuse of the tools of the kitchen has the effect of stripping the technology of its meaning, making it more “thingy” and, thus, somehow threatening or alienating.

Helen Molesworth has used Ukeles’ performances and Rosler’s video pieces to unpick a largely unquestioned binary had existed for much of the 1980s and 90s between “essentialist” feminist art and the more theory-driven works, which succeeded them in critical estimation. Essentialist works focused on more straightforward imagery of the feminine and the female — of this school, Judy Chicago’s The Dinner Party (1974-79) is considered emblematic. Theory-based works are represented in this debate by conceptual artist Mary Kelly in the Post-Partum Document (1973-79), which consists of text and artifacts that document and analyze Kelly’s relationship to and experience of mothering her son. Molesworth shows that by adding Rosler and Ukeles to this longstanding binary, we can see that all four artists are actually working in an expanded field that investigates maintenance and other forms of hidden labor.

We might venture to expand the field once more, and place these maintenance artworks in a more explicit story about technology. In her influential book More Work for Mother: The Ironies of Household Technology from the Open Hearth to the Microwave, Ruth Schwartz Cowan takes pains to remind us that the modern industrialized household is intimately dependent on the large technological systems of modernity. No plumbing, electricity, gas means no housework. No access to the manufacture of tools and appliances, textiles and packaged foods means no dinner on the table. These artworks show us how the larger technological world as the public sphere, which Ukeles and Rosler contrast with a degraded private sphere, is itself intimately dependant on the invisible labor and technological systems of the home and the invisible labors of maintenance.

Recontextualizing of the labor and tools of housework, and the slightly unsettling effect this has on audiences, is the most important feature of both Ukeles’ and Rosler’s works. They give the viewer a little glimpse of the power that has, ironically, been vested in the home and its laborers by the public sphere that insists, indeed depends, on the private remaining private. These caches of unseen power, levers that can move an economy in their numbers, are also technological levers that rely on tools and systems that have been degraded and devalued because of their connection to maintenance labor.

Ukeles and Rosler remind us the invisible labor of women and marginalized people ensures that those permitted in the public sphere, white able-bodied men, are properly clothed and housed and supported and separated from waste so that they can innovate in comfort. By surfacing this labor and critiquing the ways it has been made invisible, Ukeles and Rosler prefigure scholarly critiques about the labor of women and marginalized people and the hidden histories of maintenance technology that support a public culture of innovation.

In an interview for Artforum, Ukeles talks about how two of the most famous Minimalist artists of the 20th century, Richard Serra and Donald Judd, made artworks that “skimmed the surface” of the industrial, technological world of the public sphere. The universalism of their work depends on the labor of making them which remains invisible and only the artwork itself is available for critique. Meanwhile, Ukeles felt that as both an artist and a mother her labor had become all about care and maintenance. Her decision to commit to an artistic practice of maintenance was an investment in the personal and political act of melding her artistic self to the aspects of herself that were defined by care-work. “My working will be the work,” she declared in her Manifesto for Maintenance Art 1969!.

Ukeles’ radical intervention was to name this invisible work of cleaning, repairing, cooking, and mending Maintenance Art, and to force this labor into spaces that had always privileged the result, not the work that sustains it. Rosler’s critique of the labor of the kitchen is enacted through her alienation from kitchen technologies, a transformation of the object that was mirrored in Ukeles’ branding of the cleaning rag as an artwork and her taking possession of the building keys. These are technology stories, but not the kind we may find most familiar.

Obsession with innovation over preservation is an obsession with those who are allowed to innovate and an indifference to those who are made to maintain. It’s not just an aesthetic matter of what kind of labor seems more appealing; it’s a power structure that requires the domination of others in order to “maintain the change” created by the innovators. Yet, Ukeles meant “maintain the change” in a much more utopian sense, a thread that Molesworth notes in her expanded field of feminist-informed art. The maintenance needed to preserve positive change is itself a worthy and humanistic pursuit and deserves the same status as change itself. The technologies and labors of maintenance, wielded and performed by the marginalized, have the power to disrupt as much as they have the power to sustain.

The Fantastically Strange Origin of Most Coal on Earth – Phenomena: Curiously Krulwich
"This is a story about trees—very, very strange looking trees—and some microbes that failed to show up on time. Their non-appearance happened more than 300 million years ago, and what they didn’t do, or rather what happened because they weren’t there, shapes your life and mine.

All you have to do is walk the streets of Beijing or New Delhi or Mexico City: If there’s a smog-laden sky (and there usually is), all that dust blotting out the sun is there because of this story I’m going to tell.

It begins, appropriately enough, in an ancient forest …"

"How Fungi Saved the World"
http://feedthedatamonster.com/home/2014/7/11/how-fungi-saved-the-world

"This was the one and only time in the last 300 million years that the wood-rotting ability evolved. All the fungi today that can digest wood (and a few that can't) are the descendants of that enterprising fungus. Its strategy may have been inelegant, but wood decay played a crucial role in reversing the loss of carbon dioxide in the atmosphere and bringing about the end of the Carboniferous period.

What would have happened if white rot fungi had never evolved? We can only speculate, but it's possible the world of today would look a lot like the world at the end of the Carboniferous period – cooler, high in oxygen, and with a denser atmosphere. Dragonflies with foot-and-a-half wingspans might still roam the forests, but the plant life might still be primeval, stifled by the lower carbon dioxide concentrations. Many a homeowner may disagree, but we're lucky wood-rotting fungi evolved. "]

"For 40 million years, trees were not biodegradable.
430 million years before present, the first vascular plants emerged from early tide pools. In order to stay upright, these plants employed cellulose, a chain of simple sugars ... it was easy to make and offered rigid yet flexible support

This is from How Fungi Saved the World.

90 million years later, heralding the Carboniferous period,
plants developed a new kind of support material, called lignin. Lignin was an improvement development over cellulose in several ways: it was harder, more rigid, and, being more complex, almost impossible to digest, which made it ideal for protecting cellulose. With lignin, plants could make wood, and it lead to the first treelike growth form.

But lignin made the lycopod trees a little too successful. Because their leaves were lofted above many herbivores and their trunks were made inedible by lignin, lycopods were virtually impervious to harm.

Dead trees piled up without decomposing. Compacted by weight, they turned to peat and then to coal. 90% of all today's coal is from this period.

Wood pollution lasted 40 million years.
Finally, however, a fungus belonging to the class Agaricomycetes - making it a distant cousin of button mushrooms - did find a crude way to break down lignin. Rather than devise an enzyme to unstitch the lignin molecule, however, it was forced to adapt a more direct strategy. Using a class of enyzmes called peroxidases, the fungus bombarded the wood with highly reactive oxygen molecules, in much the same way one might untie a knot using a flamethrower. This strategy reduced the wood to a carbohydrate-rich slurry from which the fungus could slurp up the edible cellulose.

Which leads me to think:

There's a ton of plastic in the ocean. Why not engineer a fungus to rot it? Having this magical material that lasts forever is absurd. This is a controversial idea I admit. But although I agree that we need to reduce plastic pollution (via social change and by regulatory intervention), cybernetics tells me that's a fragile solution. Homeostasis is to be found in a ecosystem of checks and balances: instead of eternal plastic, we need plastic plus a plastic-rotting fungus plus an effective-but-hard-to-apply fungicide. Then balance can be found."

Engage – Michael Langan – Medium
"I know a science teacher who loves working with kids so much that he becomes depressed every June knowing that his current group of 8th graders are going to be leaving the middle school. This Science teacher has more high school kids come back to visit him than the rest of the staff combined.

Whats so special about this science teacher? He treats the kids like people. He talks with them like they are equals. He sits with them at lunch. He removes the authority boundaries in his classroom. He gives them freedom, as much as the system allows, during class.

This Science teacher stays after school with anywhere from 10 to 30 students four days a week so that the students can work on science projects for various regional and state science competitions. “If you really want to do science you have to stay after school,” the teacher often says to me with a grin.

When you walk by this science teachers class it is messy. Kids are in the hall throwing balsa wood airplanes, testing mousetrap cars, or working on the computer to learn the mandated “content.” Inside the room kids are everywhere. They are in the corners measuring levers, gluing, cutting, revising and testing. It is loud. It is chaotic and many traditional teachers in the building hate it and suggest that the “inmates are running the asylum” (real quote).

I visit often. I talk with him often. I try to relieve his angst often.
What does he have angst about? Two things usually.
The lesser of the two is the few judgmental adults. The adults that make comments. The adults that judge him passively and not so passively. The adults that remind him that their job is a bit harder because they have “rules” that need to be enforced in their rooms and its difficult “when they come from your room.”

Forget the fact that we have more regional science winners than ever before. Forget the fact that our kids are truly believing again (like they believed when they were much younger) that they like science.
None of that matters. What matters to these few angst causing adults is that the kids are harder to control due to the Science teacher giving the kids some control.

The main area where this teacher has angst is in figuring out how to engage the students. How to create an environment where all of them are in a totally absorbed state of mind without even realizing it. How does he get the kids looking and acting like a group of kids enthralled in a video game….while at the same time meeting the expectations of the institution?

How does he convince the kids to learn for the sake of learning while at the same time saying “clear your desks for the test?” How can he best keep the flow of the learning going while also making sure they know the vocab words that are on the common assessments and state tests?

I walk in this classroom nearly everyday, but when I walked in towards the end of one of his classes this past Wednesday the teacher was sitting down with the students and asking them, imploring them to help him figure out how he can engage ALL of them.
“When you think about learning, when you think back to the times that you were really motivated, what types of things were you doing?” He asked them.

A student answered, “friendly competitions.” Many other students perked up at this answer and chimed in “Yeah, like jeopardy type games, where we collaborate for the answer and stuff.”

“Or like when we made those Rube Goldberg machines and we were trying to beat the other groups.”

The bell rang and I stayed to debrief with the teacher about the conversation he just elicited.
He told me, “before you came in I was telling the students I really needed them to stop worrying about grades, and they told me “we have been taught since kindergarten that the most important thing is to get an A.”

“Yep,” I said. “getting the right answer and the importance of an A is pounded into them at school and at home.”

I continued, “what I realized, as the students were talking with you, was that they didn’t even comprehend what you were asking them. They can’t separate learning from a test. So when you ask them how can they be engaged they simply think about ways they are motivated to learn for the test.
Kids want the answer to “why are we doing this.” For some the motivator is simply for the grade. For others the motivator is, “to win the game,” or, “so I don’t get in trouble,” There are some that jump right in just for the sake of learning something new….but I don’t think there are a lot of those kids.”

Of course, saying this to the Science teacher caused him more angst. “I don’t know what I’m doing.” He responds. “I don’t know how much longer I can do this. School keeps getting in my way.”

“That means you’re doing it right,” I replied. “Its the people that have it all figured out that I worry about. The kids love you, and they respect you because they know you respect them. Plus, they love science again.”

“Yeah, but next year when they visit they are going to tell me how they are getting their teeth kicked in because Science is so hard. Am I doing them a disservice by not preparing them for that?”

“We don’t need to prepare kids to deal with things that suck. They had many classes that required them to sit, study, and regurgitate before they ever had your class. You are showing them what Science in school can be…and we never know which of your students may grow to be teachers themselves. Perhaps they will model your class.”

“Thanks bud.” He said, “But, I don’t know what I’m doing.”"

"Tucked away in a drawer in @morethanadodo's entomological collection there is a little unassuming brown note book. In it observations are entwined with a fleeting moment of a very human story...
(thread)

Beautifully written by hand with meticulously pressed specimens, this book records the observations of leaf cutter bees in the summer of 1852

Each plant used by the bees that summer was recorded & pressed. It would have required hours of careful observations & every plant was individually researched to correctly identity it

Detailed notes on the bees nesting behaviour was also recorded & observed. Tubes were diligently made, carefully fixed to the wall & patient hours spent watching the insects at work...

There are many important things to be drawn from this little note book. Data on insect behaviour supported by plenty of evidence certainly, but also a story that resonates with so many today & is something we are examining & studying right now

William was an inmate of Hanwell Asylum, the first purpose-built public asylum for the pauper insane in England & Wales opened in 1831. A little note by the warden accompanying his notebook tells of the benefit of this personal project to William & other patients mental wellbeing

So here is an example of real entomological data, an historical object in itself, evidence that supports modern day research & a very human story all contained in the corner of a drawer in a museum within a little unassuming brown notebook.

There is quantifiable evidence that in our rapidly urbanising world spending time in natural areas immersing ourselves in nature has positive affects on our mental health. I believe William found this in that summer of 1852."

"I learned not just about science from Lynn, but a whole new way of thinking. One that allows me to stand back and see the big picture - Gaia - and to lean forward and see the tiniest details - the microcosm.

She is one of the most brilliant visionaries of our time."



"1
I want to tell you about an amazing woman who changed my life, and who you need to know about if you don't already: biologist Lynn Margulis.

She died on this day, 6 years ago.
She was my main intellectual mentor in life, my friend, my second mom.

2
Lynn made quite a few major scientific discoveries.
She's best known for proving that organisms and cells that have nucleuses have symbiotic origins - that they originate from the coming together of different bacteria (and sometimes protoctists/protozoa)

3
She also discovered, with James Lovelock, that the Earth regulates itself quite a bit like an organism - particularly through the interactions of bacteria and the abiota (the non-living aspects of the environment). This is called the Gaia Theory or biogeochemistry.

4
She created a whole new theory of evolution, of which Lewis Thomas said, "Darwin was wrong, and Lynn Margulis is right." That theory is in her book Acquiring Genomes with co-author Dorion Sagan.

5
When offered potentially millions of dollars by the US govt to do research on bacteria that could help with defense, Lynn Margulis hung up on the phone on them. She said, "If it's not public, it's not science."

6
If you've heard anything about gut biomes, that is a direct result of Lynn's tireless work, yet she is rarely credited.

7
Lynn's theory of evolution came from rejecting the capitalistic cost-benefit analysis version of evolution adopted by ppl like Richard Dawkins (who has almost no lab experience comparatively). She rediscovered the science of symbiotic evolution, pioneered by Russian scientists.

8
She was well-versed in postmodern theory and studied philosophy. She was fond of saying, "the first thing scientists need to learn is that there's no objective truth."
She knew hundreds of Emily Dickinson poems by heart and lived in the house next to hers in Amherst.

9
She won just about every science award you could ever win, except the Nobel, which she no doubt would have won had she not died of a stroke on this day in 2011.

10
In spite of her being one of the most influential and profound minds of our time, she is often overshadowed by her late husband, Carl Sagan. He was a fine person, but nowhere near as arduous in his efforts or profound in his thinking as Lynn Margulis.

11
I approached her after I started my grad studies as an MFA student. Lynn tried to dismiss me at first. "What does this have to do with environmental evolution?" was the first thing she said to me.

12
"I want to take your classes," I said.
"Oh!"
She was thrilled that I was in the humanities&wanted to take science courses. I studied with her for three yrs.
She became my closest teacher. She took me to science conferences and gave me my most profound educational experiences.

13
I learned not just about science from Lynn, but a whole new way of thinking. One that allows me to stand back and see the big picture - Gaia - and to lean forward and see the tiniest details - the microcosm.
She is one of the most brilliant visionaries of our time.

14
Lynn was a huge supporter of my decision to be in gay porn. She was lustful and sexual and very much a proponent of sexual liberation.

15
Please join me in honoring this tremendous intellect today.
I wrote an essay summarizing her work shortly after her death. It's under my Birthname so that her colleagues would recognize me as the author.
Here it is: http://www.wildriverreview.com/lit/essays/lean-forward-stand-back/ "

You are Brilliant, and the Earth is Hiring :: Paul Hawken's Commencement Address to the Class of 2009 — YES! Magazine
"When I was invited to give this speech, I was asked if I could give a simple short talk that was “direct, naked, taut, honest, passionate, lean, shivering, startling, and graceful.” No pressure there.

Let’s begin with the startling part. Class of 2009: you are going to have to figure out what it means to be a human being on earth at a time when every living system is declining, and the rate of decline is accelerating. Kind of a mind-boggling situation… but not one peer-reviewed paper published in the last thirty years can refute that statement. Basically, civilization needs a new operating system, you are the programmers, and we need it within a few decades.

This planet came with a set of instructions, but we seem to have misplaced them. Important rules like don’t poison the water, soil, or air, don’t let the earth get overcrowded, and don’t touch the thermostat have been broken. Buckminster Fuller said that spaceship earth was so ingeniously designed that no one has a clue that we are on one, flying through the universe at a million miles per hour, with no need for seat belts, lots of room in coach, and really good food—but all that is changing.

There is invisible writing on the back of the diploma you will receive, and in case you didn’t bring lemon juice to decode it, I can tell you what it says: You are Brilliant, and the Earth is Hiring. The earth couldn’t afford to send recruiters or limos to your school. It sent you rain, sunsets, ripe cherries, night blooming jasmine, and that unbelievably cute person you are dating. Take the hint. And here’s the deal: Forget that this task of planet-saving is not possible in the time required. Don’t be put off by people who know what is not possible. Do what needs to be done, and check to see ifit was impossible only after you are done.

When asked if I am pessimistic or optimistic about the future, my answer is always the same: If you look at the science about what is happening on earth and aren’t pessimistic, you don’t understand the data. But if you meet the people who are working to restore this earth and the lives of the poor, and you aren’t optimistic, you haven’t got a pulse. What I see everywhere in the world are ordinary people willing to confront despair, power, and incalculable odds in order to restore some semblance of grace, justice, and beauty to this world. The poet Adrienne Rich wrote, “So much has been destroyed I have cast my lot with those who, age after age, perversely, with no extraordinary power, reconstitute the world.” There could be no better description. Humanity is coalescing. It is reconstituting the world, and the action is taking place in schoolrooms, farms, jungles, villages,campuses, companies, refuge camps, deserts, fisheries, and slums.

You join a multitude of caring people. No one knows how many groups and organizations are working on the most salient issues of our day: climate change, poverty, deforestation, peace, water, hunger, conservation, human rights, and more. This is the largest movement the world has ever seen. Rather than control, it seeks connection. Rather than dominance, it strives to disperse concentrations of power. Like Mercy Corps, it works behind the scenes and gets the job done. Large as it is, no one knows the true size of this movement. It provides hope, support, and meaning to billions of people in the world. Its clout resides in idea, not in force. It is made up of teachers, children, peasants, businesspeople, rappers, organic farmers, nuns, artists, government workers, fisherfolk, engineers, students, incorrigible writers, weeping Muslims, concerned mothers, poets, doctors without borders, grieving Christians, street musicians, the President of the United States of America, and as the writer David James Duncan would say, the Creator, the One who loves us all in such a huge way.

There is a rabbinical teaching that says if the world is ending and the Messiah arrives, first plant a tree, and then see if the story is true. Inspiration is not garnered from the litanies of what may befall us; it resides in humanity’s willingness to restore, redress, reform, rebuild, recover, reimagine, and reconsider. “One day you finally knew what you had to do, and began, though the voices around you kept shouting their bad advice,” is Mary Oliver’s description of moving away from the profane toward a deep sense of connectedness to the living world.

Millions of people are working on behalf of strangers, even if the evening news is usually about the death of strangers. This kindness of strangers has religious, even mythic origins, and very specific eighteenth-century roots. Abolitionists were the first people to create a national and global movement to defend the rights of those they did not know. Until that time, no group had filed a grievance except on behalf of itself. The founders of this movement were largely unknown — Granville Clark, Thomas Clarkson, Josiah Wedgwood — and their goal was ridiculous on the face of it: at that time three out of four people in the world were enslaved. Enslaving each other was what human beings had done for ages. And the abolitionist movement was greeted with incredulity. Conservative spokesmen ridiculed the abolitionists as liberals, progressives, do-gooders, meddlers, and activists. They were told they would ruin the economy and drive England into poverty. But for the first time in history a group of people organized themselves to help people they would never know, from whom they would never receive direct or indirect benefit. And today tens of millions of people do this every day. It is called the world of non-profits, civil society, schools, social entrepreneurship, non-governmental organizations, and companies who place social and environmental justice at the top of their strategic goals. The scope and scale of this effort is unparalleled in history.

The living world is not “out there” somewhere, but in your heart. What do we know about life? In the words of biologist Janine Benyus, life creates the conditions that are conducive to life. I can think of no better motto for a future economy. We have tens of thousands of abandoned homes without people and tens of thousands of abandoned people without homes. We have failed bankers advising failed regulators on how to save failed assets. We are the only species on the planet without full employment. Brilliant. We have an economy that tells us that it is cheaper to destroy earth in real time rather than renew, restore, and sustain it. You can print money to bail out a bank but you can’t print life to bail out a planet. At present we are stealing the future, selling it in the present, and calling it gross domestic product. We can just as easily have an economy that is based on healing the future instead of stealing it. We can either create assets for the future or take the assets of the future. One is called restoration and the other exploitation. And whenever we exploit the earth we exploit people and cause untold suffering. Working for the earth is not a way to get rich, it is a way to be rich.

The first living cell came into being nearly 40 million centuries ago, and its direct descendants are in all of our bloodstreams. Literally you are breathing molecules this very second that were inhaled by Moses, Mother Teresa, and Bono. We are vastly interconnected. Our fates are inseparable. We are here because the dream of every cell is to become two cells. And dreams come true. In each of you are one quadrillion cells, 90 percent of which are not human cells. Your body is a community, and without those other microorganisms you would perish in hours. Each human cell has 400 billion molecules conducting millions of processes between trillions of atoms. The total cellular activity in one human body is staggering: one septillion actions at any one moment, a one with twenty-four zeros after it. In a millisecond, our body has undergone ten times more processes than there are stars in the universe, which is exactly what Charles Darwin foretold when he said science would discover that each living creature was a “little universe, formed of a host of self-propagating organisms, inconceivably minute and as numerous as the stars of heaven.”

So I have two questions for you all: First, can you feel your body? Stop for a moment. Feel your body. One septillion activities going on simultaneously, and your body does this so well you are free to ignore it, and wonder instead when this speech will end. You can feel it. It is called life. This is who you are. Second question: who is in charge of your body? Who is managing those molecules? Hopefully not a political party. Life is creating the conditions that are conducive to life inside you, just as in all of nature. Our innate nature is to create the conditions that are conducive to life. What I want you to imagine is that collectively humanity is evincing a deep innate wisdom in coming together to heal the wounds and insults of the past.

Ralph Waldo Emerson once asked what we would do if the stars only came out once every thousand years. No one would sleep that night, of course. The world would create new religions overnight. We would be ecstatic, delirious, made rapturous by the glory of God. Instead, the stars come out every night and we watch television.

This extraordinary time when we are globally aware of each other and the multiple dangers that threaten civilization has never happened, not in a thousand years, not in ten thousand years. Each of us is as complex and beautiful as all the stars in the universe. We have done great things and we have gone way off course in terms of honoring creation. You are graduating to the most amazing, stupefying challenge ever bequested to any generation. The generations before you failed. They didn’t stay up all night. They got distracted and lost sight of the fact that life is a miracle every moment of your existence. Nature beckons you to be on her side. You couldn’t ask for a … [more]

Adventures in lifelong learning: Towards an Anti-Fascist Curriculum
"Yesterday's Warsaw demonstrations were shocking in their scale (60,000 nationalists marched on Poland's independence day; many calling for 'a white Europe of brotherly nations'), but were also disturbing in the way that, whilst confronted with new displays of far-right extremism almost daily - we just don't seem shocked enough. Fascism is like that, of course. It is out-there in the Charlottesville marches, echoed in the words of Nigel Farage and Tommy Robinson, yet it is also insidious. It creeps into lives - and becomes normalised in our language and behaviours. As Umberto Eco wrote in 'Ur-Fascism' (1995, p.8), 'Fascism..can come back under the most innocent of disguises. Our duty is to uncover it and to point our finger at any of its new instances – every day, in every part of the world.'

The warning signs

I won't use this blog to attempt to summarise important political discussions or try to analyse fascism in any detail; I am not a historian. But given the international rise of the far-right I believe that, as educators, we have a duty to be sensitive to these shifts and as a result should be reshaping our curricula and pedagogy to take account of it.

According to Merriam Webster, fascism is 'a political philosophy, movement, or regime... that exalts nation and often race above the individual and that stands for a centralized autocratic government headed by a dictatorial leader, severe economic and social regimentation, and forcible suppression of opposition'. Eco suggests a list of features that are typical of what he calls Ur-Fascism, or Eternal Fascism. As he states, 'These features cannot be organized into a system; many of them contradict each other, and are also typical of other kinds of despotism or fanaticism. But it is enough that one of them be present to allow fascism to coagulate around it'. The first principle, that fascism derives from individual or social frustration, is enough in itself to set alarm bells ringing. Four other key features are:

1. The cult of tradition. The desire to return to a better age, and a fear of modernism: 'Truth has been already spelled out once and for all, and we can only keep interpreting its obscure message'. (It should be noted that the first thing that fascist states seize is the curriculum).

2. Irrationalism, and the promotion of action over thought. 'Distrust of the intellectual world'.

3. Fear of difference (fascism is racist by definition). 'The first appeal of a fascist or prematurely fascist movement is an appeal against the intruders.'

4. The fostering of a spirit of war, heroism and machismo. 'Since both permanent war and heroism are difficult games to play, the Ur-Fascist transfers his will to power to sexual matters. This is the origin of machismo (which implies both disdain for women and intolerance and condemnation of nonstandard sexual 8 habits, from chastity to homosexuality).'

An anti-fascist curriculum

I suggest here that an anti-fascist curriculum should take account of warning signs such as Eco's, and should also pay heed to Lawrence Britt's 'Fourteen signs of fascism' which include Cronyism and Corruption, the suppression of organised labour, obsession with national security and identification of scapegoats as a unifying cause.

The word 'curriculum' here refers to more than just the syllabus; it incorporates all influences on a child (or adult's) education (buildings, pedagogy, classroom management, the implicit and explicit things that are taught). As teachers we often distract ourselves from the bigger picture; arguments about the specifics of practice give a sense that our classrooms operate as micro-entities, where children are unaffected by the social dysfunction surrounding them. Managing behaviour is seen as a battle of 'them versus us,' and the 'othering' of pupils causes us to neglect the development of our own self-awareness. For this reason, such a curriculum can only start with the teacher.

Below are a few ideas for what an anti-fascist curriculum manifesto might practically include. It can only ever be a guideline; wanting it to become policy or enacted in some way defeats the object of a movement that should sit outside the state. Likewise, it should not dictate the behaviour of teachers, only act as a stimulus that has the potential, not to make large-scale change, but to spark a 'line of flight' that disrupts the status quo. If any of the manifesto chimes with you or you want send any thoughts or ideas as I continue to extend it, please do not hesitate to comment or get in touch with me.

Towards an Anti-Fascist Curriculum - A Manifesto for Educators

1. We start by examining the 'fascist inside us all.'

“The strategic adversary is fascism... the fascism in us all, in our heads and in our everyday behavior, the fascism that causes us to love power, to desire the very thing that dominates and exploits us.” (Foucoult, 1983)

We recognise our own interior desire for power and accept our responsibility as educators to reflect on this with others in spirit of critical challenge. We undertake critically reflective processes that make us question our own assumptions and prejudices, such as tests of cognitive dissonance to expose gender, race, age, disability bias, and intersections of these and other identities. We examine our own values, as individuals and within our organisations and consider the roots of these and their influences on our practice. Our reflective activity extends to our roles as leaders; we aim to continually refine and develop ourselves as human beings, alongside our students.

2. We promote difference over uniformity.

This includes de-centring the Enlightenment idea of the 'perfect human' in order to augment the voices of oppressed 'others'. We celebrate the living knowledge of our students, and examine the genealogy of the subjects we teach to decolonise and diversify our curricula. We make efforts to connect with others globally to inform our practice and maintain perspective. We challenge the threat of toxic masculinity through deliberate educational approaches which liberate men and boys from the need to conform to 'gender-specific' ideals (which further male supremacy). We reflect on our own privilege.

3. We accept complexity and uncertainty.

Whilst welcoming research-informed practice, we reject the fetishisation of science and the search for the 'ultimate truths' of education theory, which can limit educational autonomy.

4. We resist the reduction of 'education' to instrumentalism.

We widen the purpose of education to take into account the socialisation and subjectification of our students (Biesta, 2010). We believe in education as the practice of freedom (hooks, 1994) and consider each subject we teach as a potential vehicle to promote agency and social justice.

5. We are pro-social, critical pedagogues.

We use teaching methods that place an emphasis on the building of community, togetherness and belonging, which have a strong critical and reflective focus. Specific teaching innovations may include philosophical inquiry, restorative practice and thinking environments (and would include the implementation of critical digital pedagogies)."

Aesop's Anthropology | Theorizing culture across species lines
[now a book:
https://www.upress.umn.edu/book-division/books/aesopas-anthropology

"Aesop’s Anthropology is a guide for thinking through the perplexing predicaments and encounters that arise as the line between human and nonhuman shifts in modern life. Recognizing that culture is not unique to humans, John Hartigan Jr. asks what we can learn about culture from other species. He pursues a variety of philosophical and scientific ideas about what it means to be social using cultural dynamics to rethink what we assume makes humans special and different from other forms of life. Through an interlinked series of brief essays, Hartigan explores how we can think differently about being human."]

Jen Bervin: Artist as Researcher de Make/Time
"Jen Bervin’s interdisciplinary work often combines art, science and writing. One recent project is Silk Poems, a poem written nanoscale in the form of a silk biosensor in collaboration with Tufts University’s Silk Lab, and also published as a book. Another project, The Dickinson Composite Series, is a series of large-scale embroideries that depict the variant markings in Emily Dickinson’s original manuscripts. Jen's work as a poet and visual artist takes her in surprising directions. She says, “I love research because I don’t know what I’ll find.”

Make/Time shares conversations about craft, inspiration, and the creative process. Listen to leading makers and thinkers talk about where they came from, what they're making, and where they're going next. Make/Time is hosted by Stuart Kestenbaum and is a project of craftschools.us. Major funding is provided by the Windgate Charitable Foundation."

OBJECT AMERICA
"The Observational Practices Lab, Parsons, (co-directed by Pascal Glissmann and Selena Kimball) launches a multi-phase project and investigation, OBJECT AMERICA, to explore the idea of “America” through everyday objects. The aim is to use comparative research and observational methods—which may range from the scientific to the absurd—to expose unseen histories and speculate about the future of the country as a concept. The contemporary global media landscape is fast-moving and undercut by “fake news” and “alternative facts” which demands that students and researchers build a repertoire of strategies to assess and respond to sources of information. For the first phase of OBJECT AMERICA launching in the fall of 2017, we invited Ellen Lupton, Senior Curator of Contemporary Design at Cooper Hewitt, Smithsonian Design Museum, to choose an object for this investigation which she believed would represent “America” into the future (she chose the Model 500 Telephone by Henry Dreyfuss designed in 1953). Researchers will investigate this object through different disciplinary lenses — including art, climate science, cultural geography, data visualization, economics, history of mathematics, medicine, media theory, material science, music, poetry, and politics — in order to posit alternative ways of seeing."
