Team fish - we need your help! We are trying to build a database of all the fish chromosome-scale genomes where sex chromosomes have been identified. Have you build one or some? Do you know someone who has? Can you post the link in the comments? Please spread the word and repost! Thank you!

Our super cool paper lead by @vdbijl.bsky.social and team! Congrats!
🚨 Super exited to see our paper on the inheritance and genetic basis of guppy color variation come out in @natecoevo.nature.comrdcu.be/eugWV

Guppy males have enormous variation in color patterns, with many combinations of ornamental spots and stripes. But where does all this variation come from?

As it's grant rejection time in Sweden too, all in one week and in the midst of a very dark November no less, this will certainly resonate with many more.

And yes! Academic institutions should check (extra!) on their researchers right now, so many of us are not okay!

Hidden labour is all over academia and open science. Let's change that! We published a paper with some suggestions, but what we're most excited about is to hear from you in the comments section at @plos.bsky.social website - go there and add your voice to the choir!
