Homo sapiens-specific evolution unveiled by ancient southern African genomes - Nature The genomes of 28 ancient southern African individuals dated to between 10,200 and 150 years before present offer insights into the evolution of Homo sapiens.

Our new ancient DNA paper has just been published!
We present 28 new genomes from southern Africa - several of them high-coverage whole genomes.
Exciting to be moving towards population-level representation of ancient southern African genetic diversity!

Fantastic paper in @science.org today revealing:
1. strong selection for cold tolerance in Beringia
2. gene-flow across the strait around 5ky
3. diversification of S. American lineages into 4 groups ~ 14k-10ky
4. followed by population crash of >40-80%

The Coming Out of a Transgender Scientist "I know that I am making the right decision because whenever I think about changing my gender role, I am flooded with feelings of relief."

We're disappointed to see Ben Barres's powerful book "The Autobiography of a Transgender Scientist" among the ~400 titles removed from the Naval Academy Library. Needless to say, we're proud to have published his book and will keep it — and his memory — alive.
