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.

”Please inhibit responsibly: Natural and synthetic actin toxins as useful tools in cell biology” I had a lot of fun going down different actin inhibitor rabbit holes with @onishilab.bsky.social on this perspective! www.molbiolcell.org/doi/10.1091/... www.molbiolcell.org/cms/10.1091/...

We’re organizing a conference at @ijmonod.bsky.social in Paris, January 2026, in memory of M.P. Sheetz — pioneer in cell mechanics and mechanobiology, co-discoverer of kinesin, and founder of @mbisg.bsky.social. Join us to explore his legacy. mikeinmemoriam.sciencesconf.org

🌱✂️ 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. #PlantScience #CellBiology #Arabidopsis @camilagoldy.bsky.social @rdplab.bsky.social www.biorxiv.org/content/10.1...

Microtubules: the architect of muscles. Watch how microtubules transport mitochondria in proximity to energy consuming sarcomeres in muscles of flies and mice. @jeromeavellaneda.bsky.social @nunoluis.bsky.social @ibdm.bsky.social with @gomeslabo.bsky.social www.sciencedirect.com/science/arti...

We have used many microwells to confine biochemical reactions in our recent studies. We wanted to share the protocol for preparing and characterizing microwells; this protocol is now published here : www.frontiersin.org/journals/cel... @manuelthery.bsky.social @lblanchoin.bsky.social
