I am very excited to announce the opening of the submission site for the upcoming Conférences Jacques Monod on Developmental Biology, May 18-22, 2026 cjm.sb-roscoff.fr/en/conferenc... @lionlchristiaen.bsky.social and I have an exciting program of speakers and slots for selected short talks, etc.

Our latest paper on a histone methyltransferase-independent function of PRC2 controlling small RNA dynamics during programmed DNA elimination in Paramecium is now published in #NAR. #RNAbiology #TEsky #smallRNAs #PRC2 #DNAelimination 1/5 academic.oup.com/nar/article-...

If you’re interested in joining our team as an Assistant Engineer, don’t hesitate to get in touch! Exciting projects, a friendly and dynamic team - all based in the beautiful French Riviera! @institutBiologieValrose - @cnrscotedazur.bsky.social

Neuronal diversity is written in transcriptional codes 🧬. But what is the logic of these codes that define cell types and wiring patterns? To find out we built a #scRNAseq developmental atlas of the Drosophila nerve cord and linked it to the #connectome 🪰🧠 #preprint thread ⬇️1/8

I'm looking to recruit a post-doc to help push forward our growing interests in insect ecotoxicology. Apply here by Nov 30th! (thanks for reposting) career5.successfactors.eu/sfcareer/job...

We are happy to share our latest work in @nature.com . We study the genomic and cellular basis of facultative symbiosis in Oculina patagonica - a Mediterranean coral remarkable for its ability to survive long periods without algal symbionts. Led by Shani Levy and @xgrau.bsky.social rdcu.be/eLbaZ

Still can’t quite believe it 💫 I’ve received the L’Oréal-UNESCO For Women in Science “Jeunes Talents” France 2025 award! I’m so deeply honored — this recognition means so much to me, both as a scientist and as a woman who loves research. 💙🔬 1/3

Rest in peace Jane Goodall, a true giant among scientists. Your breakthroughs into the secret lives of chimpanzees viewed through an anthropomorphic lens – without yet knowing that science had forbidden it – changed science forever, and with it how we see ourselves.

Excited to share our last paper describing how intestinal stem cell migration promotes gut regeneration! www.nature.com/articles/s41...

New short paper from our lab @currentbiology.bsky.social, in which we discover of a new mode of cell motility for choanoflagellates: flagellar gliding. www.cell.com/current-biol... - A 🧵

To rehabilitate the general view of women's contributions to the history of science, the CNRS is part of a commission that aims to inscribe the names of 72 female scientists on the Eiffel Tower. 🗼 #WomenInScience

Our study on a male-essential microRNA and the evolution of other dosage compensation mechanisms in birds is now out in Nature! www.nature.com/articles/s41...

If you’re interested in sexual dimorphism, epigenetic, evolution and live imaging, joins us for your PhD!

An ERC funded post doc position at the iBV in Nice ibv.unice.fr/job-offers/e...

Wonderful meeting and opportunity to meet other fellows!

Super excited for our new preprint on the role of tissue mechanics on the neurophysiology and behavior of Ciona. A tour de force by @midlangandreas.bsky.social and other lab members combining tension sensors, calcium imaging, optogenetic tools and of course behavior. More to come soon.

Submit your art and join us in beautiful San Juan

This stunning pic of sensory neurons in a #Drosophila larva received a near-unanimous vote from the @plosbiology.org team for the featured image of our Jan 2025 issue. It was made by Pankajam Thyagarajan in Melissa Rolls' lab. The neurons are magenta and the overlying epidermal cells are green.

I'll be in Nice tomorrow to give a keynote seminar at Institut de Biologie Valrose (iBV), please come at 11 to here about the neuronal cytoskeleton!

Sensing food is a complex multisensory experience. A study of food hardness preference in #FruitFly larvae by @simon-sprecher.bsky.social &co reveals that gustatory organ sensory neurons can perceive cues of both chemical & mechanical stimulation 🧪 @plosbiology.org plos.io/3CEv5FJ

Former student was running a paper mill, says University of Manchester 'A search of Pubmed turned up 10 articles by Quazi published between 2021 and 2022, on topics ranging from the gut microbiome to AI in medicine.' @retractionwatch.com retractionwatch.com/2025/01/30/f...

Registration and abstract submission for YEN 2025 is officially open! We are looking forward to seeing you at the 17th Young Embryologist Network Conference on the 19th May 2025. Attendence is FREE thanks to our amazing sponsors: @biologists.bsky.social @10xgenomics.bsky.social and Azenta.

Donner 75% des moyens a 25% des labos, il va y avoir évidemment 75% des chercheur·e·s contre, mais peut-être 25% de chercheur·e·s pour – et c'est sans doute ça le plus triste

… and the return journey. Thanks to Bruno Hudry and the Institut de Biologie Valrose for the invitation!

Where did our neck muscles come from?🧪 Here's our #evodevo #devbio deep dive feat. #zebrafish, mouse, axolotls, & more! Led by Eglantine Heude & Tajbakhsh lab at Pasteur, the team at National Museum of Natural History France, & lab alumni Karin Prummel & Rob Lalonde. www.nature.com/articles/s41...

Happy to share link to pdf/video of lecture at College de France on « Encoding, decoding & representations of space». I present how length scales are defined in biology, Shannon information theory, positional information & patterning in guided + self-organised systems. Enjoy! tinyurl.com/y85ft5nj

(please amplify) 4% of scientists face an important barrier to an the ENTIRE FIELD of single-cell genomics and here is why

We have two open PhD positions in my group at @crg.eu. We are seeking candidates with a background in computational and/or molecular biology, and with a broad interest in evolutionary biology, gene regulation, and comparative genomics. 📅Apply before January 12 here: www.crg.eu/en/content/t...

Looking for a tag to localise fluorescent proteins to the plasma membrane? Unsure which tag might work in your species? We generated a toolkit of 11 membrane-localising tags, which can be screened rapidly by microinjecting mRNA in your species of interest. 1/4 www.biorxiv.org/content/10.1...

SOX and POU are crucial Transcription Factors in animal development, believed to be innovations of this group. Here we find them in unicellular relatives of animals. And hold tight, you can use a choanoflagellate 🦠 SOX gene to make a full chimeric 🐁 ! Read more here 🧵: rdcu.be/d0dPN 1/6
