Final version @nature.com of our paper describing unconventional multicellular development in a choanoflagellate inhabiting an extreme environment. A ton of new data since the first @biorxivpreprint.bsky.social preprint (which we've kept updating).
A brief 🧵 (carried over from the old place)
As independent tests, we also combined cells stained with distinct fluorophores, and found they aggregated into chimeric colonies. We also showed multicellular development was not abolished by cell cycle inhibitors. Thus our fear became a finding: C. flexa can aggregate.

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... 🤩

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.

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.

Le CNRS a proposé au Sénat des mesures fortes pour renforcer la place des femmes en science. Cette sous-représentation n’est pas une fatalité : elle résulte de biais, de stéréotypes, d’inégalités et de violences tout au long des parcours scolaires et professionnels.
#Communiqué 🗞️ En 2026, pour célébrer ses 40 ans, le @museeorsay.bsky.social devient un véritable théâtre du vivant. Deux soirées dans la Nef plongeront le public dans un spectacle immersif au coeur des dynamiques cellulaires donnant vie à l’architecture de la gare.

👉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

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.

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

Using 16 (!) cryo-EM structures, we uncovered how the three proteins coronin, cofilin and AIP1 work together to rapidly disassemble actin filaments.

🌱✂️ How do plant cells decide where to divide?
Our work shows that actin can override the geometric rules—guiding cells to divide in alternative orientations.
