[Message de service] Vous pensez/voulez postuler à un poste de Maître de Conférence ? Fort bien. Avez-vous pensé à vous inscrire pour passer votre qualification ? C'est en ce moment qu'il faut aller s'inscrire en ligne... (odyssee.enseignementsup-recherche.gouv.fr)

Excited to share our recent work from @lowelab.bsky.social on the intersection of life history and cell type evolution: www.biorxiv.org/content/10.1...

Our study, just published in #ScienceAdvances and funded by @hfspo.bsky.social, explores the post metamorphic cell composition of the sea urchin juvenile, revealing that its body is head-like. Long considered brainless creatures, they’re all brain instead! www.science.org/doi/10.1126/...

AAVs are crucial vectors for delivering biosensors into neurons! Using AAV delivery, we perform two-color imaging of calcium and potassium transients in neurons. These AAVs are now available from @braincase.bsky.social www.ebraincase.com/news/new-pro...

Congratulations to Oğuz Akar who was awarded the title of Doctor in Philosophy in Cell and Biology yesterday!

Sea urchin metamorphosis is maybe one of the most radical event in developmental biology. In just about an hour, these little pluteus larvae completely reorganize their entire body plan. Very happy that this video got awarded an honorable mention by #NikonSmallWorld 😃

Modeling whole ascidian embryos for #forksningdagene 😉🧪🧬🔬#devbio

Our new collaborative paper with Cyndi Bradham's lab at BU, led by first author @alexandralion.bsky.social is out in @devbiol.bsky.social & featured on the Sept 2025 cover! 😀🥳 PFAS (PFOA & GenX) disrupt sea urchin embryo development! Cover art: embryos + flow fields 👉 doi.org/10.1016/j.yd...

I am very happy to announce that the Echinox Lab will open in the BIOM unit at @obs-banyuls.fr in January 2026!! 🥳 We will use several echinoderm species to study animal body plan evolution. 🔽 Check our brand new lab website if you want to learn more about our future research www.echinox.org

Welcome! Great to have you here! #ascidian #DEEVA #WindyBanyuls @biom-banyuls.bsky.social @cnrsbiologie.bsky.social @obs-banyuls.bsky.social

La quasi-totalité des méduses mènent une double vie : fixées dans les fonds marins ou libres dans l’eau. Mais certaines ont échappé à ce cycle et passent toute leur vie à dériver. Selon une nouvelle étude, ces espèces dites holoplanctoniques ont colonisé l'Océan. Dériver pour mieux régner !

👨‍🔬 Retrouvez Lucas Leclère,chercheur au @biom-banyuls.bsky.social dans l'équipe @cnidevo.bsky.social, dans l’émission "Avec Sciences" sur @franceculture.fr ! Il y parle du fascinant destin des méduses holoplanctoniques. 🎧 Écoutez l’épisode : www.radiofrance.fr/francecultur... @obs-banyuls.fr
