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

Tipsy bats and perfect pasta: Ig Nobels celebrate ‘improbable’ research
Nature - The annual awards are a celebration of weird but thought-provoking science.

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.

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
