New paper! In female mammals, one X-chromosome is inactive in each cell. In some cats, this causes typical color patterns, depending on which X is active and the color it codes for. The @eddaschulz.bsky.social lab found a new regulatory principle behind X-inactivation. 1/2 Note: AI generated image

​My loyalties are split for this year's Ig-Nobel favorite. It's a dead heat between the physicist who analyzed how to stir pasta and the theorist who suggested to eat teflon to reduce calories.
​Both feel equally essential to the future of humanity. #IgNobel #Science

Highlights of this year’s Ig Nobel recipients include a nutrition prize for studying the preferred pizza toppings of rainbow lizards at a seaside resort in Togo

A common type of ant in Europe breaks a fundamental rule in biology: its queens can produce male offspring that are a whole different species

‘Almost unimaginable’: these ants are different species but share a mother
Ant queens of one species clone ants of another to create hybrid workers that do their bidding.

Does population size shape protein coevolution?
I explored this in my talk today at the MPI for Evolutionary Biology.
Our work in mammals suggests the answer is yes - genetic drift is a major determinant of compensatory mutations.

Please come and see Jinyang’s purr-fectly interesting talk at the #ESEB2025 the coming Thursday 3:45 PM (Meeting Room 116) on Polarizing SNPs without outgroup.

(I won’t be there, busy.)

Very happy for the chance to share a snapshot of my Master’s project at the MPI for Evolutionary Biology, in Julien Dutheil’s group. I’ve been tracing how the effective population size drives intra-protein compensatory mutations - tiny edits that help life stay in balance. @mpi-evolbio.bsky.social
