This epic paper, which has been a heroic 10 year journey for the lead author, Ricardo Barrientos, is finally out in Cell today! Many thanks to all co-authors, especially Billie Meadowcroft and Andela Saric for their beautiful MD simulations www.cell.com/cell/fulltex...

Basement membrane turnover controls cell shapeBasement membranes are scaffolds of proteins, like collagen, that give organs shape. During development, basement membranes must adapt to the growing organ. We infer how fast the basement membrane ada...www.cell.com

Thrilled to share our new paper on cell extrusion. A beautiful study with a tremendous amount of data, led by the fantastic @fanny-wodrascka.bsky.social ! www.biorxiv.org/content/10.6...

Les nouvelles règles envisagées pour l'ANR sont plus qu'inquiétantes. Elles porteraient un immense coup d'arrêt à la recherche fondamentale en France, surchargeraient les jeunes chercheurs, et n'attendraient sans doute même pas leur objectif (apparent) de réduction du nombre de candidatures

🪲🪰 Our preprint is out! This was a team effort with @wolframponisch.bsky.social, @matthewabenton.bsky.social and Ewa Paluch. We asked whether Drosophila and Tribolium use the same cell behaviours to fold their embryos during gastrulation. 🧵👇 www.biorxiv.org/content/10.6...

Morphospace analysis reveals divergent cellular behaviours driving tissue internalisation during insect gastrulationDuring gastrulation, embryonic epithelia undergo large-scale remodelling to internalise the mesoderm. Whether the cellular mechanisms underlying these tissue deformations are conserved across species ...www.biorxiv.org

New research from @fpichaud.bsky.social and University of Seville researchers found that developing fruit fly retinas behave like metamaterials, folding from flat cellular patterns into precise 3D structures. www.ucl.ac.uk/life-science... #UCLLifeSciences #Biomaterials #Metamaterials

Fly eyes reveal nature's blueprint for metamaterialsScientists have discovered that fly eyes develop as natural programmable metamaterials, revealing an "origami" blueprint that could inspire biomaterials, tissue engineering and regenerative medicine.www.ucl.ac.uk

I wanted to like QED's new 1% preprint ranking. I really did. But the more I looked at the data, the more uncomfortable it made me. Here is my full peer review. open.substack.com/pub/blekhman...

[ #VeilleESR #LPPR ] Durcissement des règles d'attribution pour l'appel à projets générique ANR. Notamment : réduction du nombre de dépôts et augmentation du délais de carence. L'argumentaire est : plus les scientifiques ont besoin de l'ANR, moins il faut que les scientifiques sollicitent l'ANR.

Our Stem Cell Course #ASCB is back! After 2nd day, @institutpasteur.bsky.social @tajbakhshlab.bsky.social, @zenlabpasteur.bsky.social, Barbara Gayraud-Morel, and great interactive students. Laurence Daheron, Frank Yates, Michel Cohen-Tannoudji covered pluripotency and generating hiPSCs. Great team!

As Editor of @dev-journal.bsky.social I get asked "What are you doing about your impact factor?" In our new editorial we say: Ask not what Dev can do for the impact factor. Ask what you can do for Dev's IF The IF is about how we all cite, review & assess each other's work doi.org/10.1242/dev....

This will be on 26 June in Paris! 🤩You are welcome to join and participate in this exciting 1-day conference at the College de France on Biological computational accross areas of biology. Fantastic speakers. Free, no registration, at the heart of Paris on a lovely season. Worth planning a weekend…?

📢 We are looking for a Junior Group Leader to join us at @institutcurie.bsky.social! Having joined the department just over a year ago, I can honestly say that it is an exceptionally stimulating and supportive scientific environment, filled with outstanding colleagues — all in the heart of Paris.

🏅 Congrats to Elisa Gomez‑Perdiguero & Brice Bathellier, winners of the 2026 Vallery‑Radot Prize ! 👏 Their work advances our understanding of immune cell origins & how the brain processes sound — showcasing Pasteurian excellence. 💙 @labnf.bsky.social

Happy to share our new review on biophysical principles of cell competition and elimination: www.cell.com/trends/cell-... With @bladoux.bsky.social and @rmmege.bsky.social, we discuss mechanical fitness, how loser cells are removed through various strategies and how forces can effect their fate

💥 🚀 New preprint! 🎉🥳 How do hundreds of organelles organize themselves into near-perfect patterns inside a cell, without a blueprint? We dive deep into how basal bodies (BBs) self-organize in MCCs - and how actin actively tunes their dynamics into order 🍪 🧵👇 (1/17)
