            As the 20th-century world recoiled from the horrors of Nazi Germany and the eugenics movement, we learned how economic, political and social circumstances produced the racial differences that science had once claimed to be "natural". Race came to be recognised as a social construct - an aspect of social choices rather than a reflection of biological differences between racial groups.
The constructionist thesis gained popularity after the second world war and encouraged advances in civil and human rights for racial minorities. And with the Human Genome Project finding in 2000 that all humans are more than 99 per cent alike, many thought genomics would put the final nail in the race coffin.
But a funny thing happened on the way to the funeral. Shortly after the HGP's finding, several research projects began focusing on mapping this less than 1 per cent of human genetic variation onto social categories of race.
This small variation reflects millions of SNPs (single nucleotide polymorphisms), some of which may loosely correlate with geography. Yet the resilience of linking such differences and disparities to biological mechanisms...

            For two years, a panel of scientific experts, clinicians, and patient advocates had been hammering out ways to increase community engagement in National Institutes of Health-funded science. When they presented their road map to the NIH Director Jay Bhattacharya last...

[OHSU News/Christine Torres Hicks]
On September 30th, a team of 21 scientists from Oregon Health & Science University (OHSU) published a significant paper in Nature Communications, with a scientifically accurate but, to many, somewhat abstruse headline:
Induction of experimental cell division to generate cells with reduced chromosome ploidy
The lead authors were Shoukhrat Mitalipov, recently described here as “a push-the-envelope biologist,” and his long-term colleague Paula Amato. (Recall that in July the pair had co-published with...

            Before dawn on a March morning, Doug Whitney walked into a medical center 2,000 miles from home, about to transform from a mild-mannered, bespectacled retiree into a superhuman research subject.
First, a doctor inserted a needle into his back to...

            Consider, if you will, the translucent blob in the eye of a microscope: a human blastocyst, the biological specimen that emerges just five days or so after a fateful encounter between egg and sperm. This bundle of cells, about the size of...
