A wonderful team effort to characterize the actions of HSD17B2, a gene that helps some #ruff males to dial down their testosterone levels, got published @science.org (1/n)

A single gene underlies male mating morphs in ruff sandpipers, a new Science study finds. The results show how evolutionary changes in a single gene's structure, sequence, and regulation can drive significant diversity within a single species. Learn more in our new issue: https://scim.ag/4arzNmU

How to get rid of too much testosterone? A new study in @science.org by @chorlnev.bsky.social and @jasmineloveland.bsky.social found a single gene in ruffs that down-regulates testosterone directly in their blood. Read more: www.bi.mpg.de/news/2025-01...

Thanks all for joining the launch of the @dfg.de funded FOR5795 HyperMet. Effects of skeletal muscle hypertrophy and atrophy on metabolic health! We started with resistance training and had talks to introduce HyperMet and advanced metabolic research.
