Really excited to share our new paper in @nature.com! We uncovered how a physical instability of the cytoplasm coupled with the cell cycle drives cytoplasmic partitioning in early embryos #zebrafish #drosophila. Read more in this🧵 www.nature.com/articles/s41... 🤩 @poldresden.bsky.social @mpi-cbg.de

Happy to highlight our collaborative work from our @ijmonod.bsky.social team with @destriano.bsky.social, B. Goyeau and M. Chabanon. Cytoplasmic crowding acts as a porous medium that hinders macromolecular diffusivity. Plus: a clever way to measure cell volume. www.pnas.org/doi/10.1073/...

A few seconds of eternity: From microscope to museum❣️ It was truly delightful to be part of this project, celebrating life as a continuous dance of creation, collapse, and renewal. 🔄 Kudos to @manuelthery.bsky.social @lblanchoin.bsky.social #cytomorpholab members, and @museeorsay.bsky.social

We spend way too much time manually analyzing #microtubules 🔬 Together with Mario, Justus, Dominik, Felix & Erik we used synthetic data and foundation models to build a fully automated segmentation pipeline.

👉Excited to share our latest work @natmicrobiol.nature.com, revealing a decrease in cytoplasmic crowding during filamentous growth in the human fungal pathogen Candida albicans. Furthermore we found that inhibition of ribosome biogenesis can trigger filamentous growth in this pathogen rdcu.be/eT1Su

🚨 Je cherche des chercheur-ses de toutes disciplines pour un doc radio pour parler de leur sujet de recherche mais aussi de leur quotidien (une journée type au labo). Contrainte supplémentaire, le labo doit être hors de Paris. Plus d'infos : forms.gle/hw9wH2p5UH4A...

Cells can hunt prey, solve mazes, and learn from past experience. Does this mean they can think, at some level? Find out more at our upcoming session on "Cell Behavior and Cognition" at the ASCB/EMBO #cellbio2025 meeting, Saturday 1-3 pm rm 115.

#RésultatScientifique 🔎 | Comment les filaments d'actine s'organisent à l'intérieur des cellules et des tissus vivants 🔬 @institutfresnel.bsky.social 🤝 @univ-amu.fr @centralemed.bsky.social @cnrs.fr 📍 @cnrs-dr12.bsky.social

is there a direct crosstalk between actin and vimentin intermediate filaments? Our work shows that vimentin promotes actin assembly by stabilizing ATP-subunits at the barbed end. Fantastic work done by @lilianpaty.bsky.social with @romet-jegou-lab.bsky.social www.biorxiv.org/content/10.1...

Very excited that my final postdoctoral work is now online in Cell @cellpress.bsky.social. www.sciencedirect.com/science/arti... Using 16 (!) cryo-EM structures, we uncovered how the three proteins coronin, cofilin and AIP1 work together to rapidly disassemble actin filaments.
