Where Computing Is Headed—Beyond Quantum
Feb. 4, 2020 | WSJ | By Sara Castellanos.

Startups are coming up with new ways to make computer chips and store huge amounts of data in DNA........dozens of companies gaining interest from investors and corporations because of their novel approaches to computing. They are using light, quantum physics, molecular biology and new design methods to build chips and create data-storage techniques for future computing demands.

How white supremacists respond when their DNA says they’re not ‘white’ | PBS NewsHour
BY NSIKAN AKPAN  August 20, 2017

Genetic ancestry companies assess a person’s geographic heritage by analyzing DNA markers in their autosomal DNA (for individual variation), mitochondrial DNA (for maternal history) or their Y chromosome (for paternal history). The latter two sources of DNA remain unchanged from parent to child to grandchild, aside from a relatively small number of mutations that occur naturally during life. These mutations can serve as branch points in the trees of human ancestry, Panofsky and Donovan wrote, and as DNA markers specific to different regions around the world.

When genetic anthropologists examine the full scope of humans, they find that historical patterns in DNA markers make the case that everyone in the world came from a common ancestor who was born in East Africa within the last 100,000 to 200,000 years. Plus, groups intermingled so much over the course of history that genetic diversity is a continuum both within American and Europe,

Scarcity, Fountain of Innovation - The CSR Blog - corporate social responsibility
Sep. 16 2010 | Forbes | Posted by Gregory Unruh. "Panel members
came at scarcity from diverse disciplines.(e.g. perspective of
environmental sustainability), where scarcity has been a polemic since
at least the 18th century....Talk of resources scarcity, tends to focus
on energy and material constraints, but that’s only ½ of the story
because it overlooks a 3rd important resource: human
creativity (jk: human ingenuity)...Scarcity is relative. And the mere act of perceiving
scarcity changes the game...Great designers understand this. Charles
Eames says design is all about innovating around constraints. And it’s
the constraints – the scarcity – that fires the designer’s
creativity...Nature is the ultimate example of leveraging the power of
self-imposed constraints. 95% of every living thing is made out of just 4
elements: C, H, O2 and N. Scarcity of design options has not limited
nature’s creativity. There are tens of millions of diverse species and
even more miraculous functions.

Dawn at the Museum - Olivia Judson Blog - NYTimes.com
August 4, 2009 | New York Times | Olivia Judson Blog. The
Oxford Museum ranks in the annals of evolutionary history because, just
after it opened in 1860, it was the scene of a debate between Samuel
Wilberforce, Bishop of Oxford, and Thomas Henry Huxley, a friend and
colleague of Darwin’s. At the time of the Huxley-Wilberforce debate,
natural history museums were not places to study evolution, they were
catalogs of nature. Large and impressive catalogs, but catalogs all the
same. While acting as hugely important stores of information about
biodiversity, both now and in the remote past, they have also become
something much more--they can can provide an invaluable source of
knowledge about recent genetic changes.
