Hi, I'm setting up a peer support platform for ECRs in ecology & evolution in China, aiming to address a huge problem --- academic burnout driven by hyper-competition and a system that often prioritizes elite background/title over actual research.

some think this field, despite recent Nobel to Ambros and Ruvkun, doesn't have much surprises left. but, do we EVEN KNOW WHAT a miRNA precursor LOOKS LIKE? we found some conserved miRNA hairpins up to 10x longer than suspected. this is mir-12, just bonkers! 1/n

Music to my ears. This is brilliant. Either 90% of us can claim to be better musicians than Beethoven or… maybe just maybe polygenic scores aren’t perfect?
If someone you know buys into claims about "genetic optimization" of embryos using polygenic scores of cognition, just send them our 2024 paper on Beethoven & musicality. We wrote it to help communicate limits of individual-level genetic predictions & complexity of links between DNA & behaviour. 🧪👇
Notes from Beethoven’s genome
Wesseldijk et al. compare the genomic information collected from Ludwig van Beethoven
with population-based datasets used to quantify musical achievement.

It is sad that even basic research needs to be defended with utility. For me, basic research is in the same category as art: civilized societies can't do without it, because we all want to know who we are and what our place in the natural world is -- questions that only science can answer.
