Just caught up on this fascinating paper in Science in August. It reports evidence of strong selective pressure from breeding of horses around 5000-3000 years ago in Central Asia. One reason it's interesting is that the selection is *really* strong... /1

Selection at the GSDMC locus in horses and its implications for human mobility

Horsepower revolutionized human history through enhanced mobility, transport, and warfare. However, the suite of biological traits that reshaped horses during domestication remains unclear. We scanned...

Earlier this year, ProPublica found that the sepsis rate in second-trimester pregnancy loss hospitalizations increased by more than 50% under Texas’ abortion ban.

Here’s how we did our analysis.

Texas Won’t Study How Its Abortion Ban Impacts Women, So We Did

Since Texas banned abortion, no one has studied the statewide effects on pregnant women experiencing complications. Here’s how we sifted through data on millions of pregnancy hospitalizations and anal...

I’ve said it before and I’ll say it again, the Cheers theme song is fitting for really any time in life….including our current timeline

“Making your way in the world today
Takes everything you've got
Taking a break from all your worries
Sure would help a lot
Wouldn't you like to get away?”

BREAKING: A federal judge reversed National Institutes of Health's terminations of hundreds of critical research grants that were canceled because of their alleged connection to disfavored topics, including diversity, equity, inclusion, and gender identity.

This is a major win for public health.

If thousands of scientists say that political interference with grants assessment is going to destroy the scientific integrity of federal grants, the agency will have to explain why the rule doesn’t do that (which it can’t because this is precisely why the new regulation is being instituted).
