Our research on reptile pigmentation is featured on the cover of Genetics 🧬🦎 We uncover how mutations in TYR, SLC24A5, and OCA2 shape hypomelanism in snakes & geckos, revealing modular and flexible melanogenesis. 🔗 academic.oup.com/genetics/art...

Beautiful weather for a visit to the @institutcurie.bsky.social, where I’m speaking about the molecular and mechanical regulation of skin appendage development 🐣 🐊 🔬

Just in time for the New Year we have a new preprint up that focuses on white cells, often used as ornaments in fish. www.biorxiv.org/content/10.6...

Very excited to share that our latest paper is out in Science! We show that the type specimen of Nanotyrannus—an isolated skull—is fully grown, showing that it is not a juvenile Tyrannosaurus rex but a distinct species (1/12) www.science.org/doi/10.1126/...

@rorylcooper.bsky.social gave a very nice talk (with gorgeous art) on crocodilian head scale patterns. Fav finding was a potential simple explaination mechanisms driving scale diversity between species.

I didn't manage to summarise all of @rorylcooper.bsky.social 's seminar today, but here we have sonic hedgehog inhibition pausing chicken embryo feather development at stage E9, and halting chicken embryo feather development at stage E11. Thank you for the great talk on skin patterning.
