Life in Deep Earth Totals 15 to 23 Billion Tonnes of Carbon—Hundreds of Times More than Humans | Deep Carbon Observatory
Barely living "zombie" bacteria and other forms of life constitute an immense amount of carbon deep within Earth's subsurface—245 to 385 times greater than the carbon mass of all humans on the surface, according to scientists nearing the end of a 10-year international collaboration to reveal Earth's innermost secrets.

3D.FAB bioprint “living bandage” within regenerative medicine research project
Clinicians of various specialties require autologous implantable tissues to repair and replace damaged tissue caused by diseases or trauma. With 3D bioprinting it is possible to manufacture such tissues, however, its biomechanical characteristics reduce its capabilities to be sutured.

As a result, 3D.FAB, a French additive manufacturing platform, is developing a “living bandage” using 3D bioprinting and direct additive manufacturing. According to the platform’s project “STRESSKIN,” such technologies can be positioned in this field of regenerative and personalized medicine to address this issue.

Deep life: exploring microbial dark matter (Lauren Fuge, Cosmos - 11 Dec. 2018)
“Among the findings [of the Deep Carbon Observatory] are the nature and extent of the microbial biosphere deep underground. It turns out that 70% of the planet’s bacteria and archaea live in these extreme environments, not only under radical pressures and temperatures, but also in pitch darkness with restricted nutrient sources.”

AlphaFold @ CASP13: “What just happened?” « Some Thoughts on a Mysterious Universe
In a delicious twist of irony, we the people who have bet their careers on trying to obsolete crystallographers are now worried about getting obsoleted ourselves.

What is worse than academic groups getting scooped by DeepMind? The fact that the collective powers of Novartis, Merck, Pfizer, etc, with their hundreds of thousands (~million?) of employees, let an industrial lab that is a complete outsider to the field, with virtually no prior molecular sciences experience, come in and thoroughly beat them on a problem that is, quite frankly, of far greater importance to pharmaceuticals than it is to Alphabet. It is an indictment of the laughable “basic research” groups of these companies, which pay lip service to fundamental science but focus myopically on target-driven research that they managed to so badly embarrass themselves in this episode.

Then imagine that a pharmaceutical company suddenly enters ImageNet and blows the competition out of the water, leaving the academics scratching their heads at what just happened and the tech companies almost unaware it even happened. Does this seem like a realistic scenario? Of course not. It would be absurd. That’s because tech companies have broad research agendas spanning the basic to the applied, while pharmas maintain anemic research groups on their seemingly ever continuing mission to downsize internal research labs while building up sales armies numbering in the tens of thousands of employees.

And if you counter with the argument that machine learning is not pharma’s core expertise, then you only prove my point: why isn’t it?

Who made the advance is less important than the fact the advance was made, and we should unselfishly rejoice in this fact. I say this cognizant of the fact that my own emotions do not entirely coincide with the sentiment I just espoused, but also cognizant of the fact that we are all adults, and that we must and ought to assess this rationally without letting our tribal affiliations cloud our judgement.

This plant produces a "hot" chemical thousands of times stronger than the hottest of peppers. It literally overloads and damages pain nerves (and temperature nerves and no others) and a better-than-opioids treatment for pain in extreme cases.

Leonardo da Vinci's tree rule may be explained by wind
For some tree species, Leonardo noted, the cross-sectional area of a ranch before a fork is equal to the sum of the cross-sectional areas after the fork. The previous explanation is implausible; this author shows that constant resistance to wind forces could explain it.
