C'est sorti ! Un reportage des équipes du CNRS sur nos recherches et l'importance d'étudier la diversité des chauves-souris et leur evolution. Une occasion aussi de découvrir la splendeur de Trinidad et nos collaborateurs grâce aux images de notre film Spectral
@erc.europa.eu @isemevol.bsky.social
INÉDIT 🎬 Comment les chauves-souris ont-elles donné naissance à une telle diversité ? 🦇
Avec plus de 1500 espèces, leur évolution est fascinante.
Pour le savoir, direction les grottes et les forêts de Trinité-et-Tobago. 🌴

This is it. This is what everyone is enabling by humoring genAI: you spend months writing something that took you years to get at, for an opaque algorithm that a few control to spit a number and cut you off right there and then. This is what we're up against 🧪
Had a UKRI funded grant proposal rejected at the "AI triage stage". "This AI-based triage was used only to identify approximately 50% of the strongest proposals to take forward to full human review." 🧪 #academicsky

🦇 Bat1K's biggest paper yet is out. Largest bat genome + fossil study ever: 103 genomes, 44 fossils, 137 researchers. We rewrote the bat family tree! Bats likely originated in Europe ~65 million years ago, not Asia, Africa or Americas. @bat1kgenomes.bsky.social

Where did bats come from?🦇🌍

After decades of debate, the biggest bat genome + fossil study ever done has an answer - and it’s not where anyone expected!

🤩OUR PHASE 1 FLAGSHIP is out today in nature! doi.org/10.1038/s415...

Reference genomes and fossils revise bat family phylogeny and biogeography - Nature
An updated phylogeny of bats is presented, based on new genome assemblies and many ancient fossils and including all known bat families.

NEW PREPRINT!
An evo-devo look at how new cerebellar nuclei are made. Spoiler: it’s all driven by region-specific excitatory progenitors in the early rhombic lip; inhibitory neurons fill in later. If you care about brain evolution or cerebellar development, check it out: tinyurl.com/CNdevelopment

Must admit, ever since I was a kid, I’ve dreamt of seeing microscopy images of #protists in @lemonde.fr
Today, protists are everywhere, and several images were taken by the team. And seeing #ichthyosporeans there too?! 🥹
One step closer to showcasing the beauty of the invisible microbial world. 🔬✨

21627 applications. Nothing to celebrate here. Impossible to evaluate fairly & safely. Neither the science (too diverse & possibly LLM generated) nor the soft criteria (likely LLM generated). Without an interview stage - a security risk!
