HHMI adopts Plan U journals.plos.org/plosbiology/...

Happy to share the Biodiversity Cell Atlas white paper, out today in @nature.com. We look at the possibilities, challenges, and potential impacts of molecularly mapping cells across the tree of life. www.nature.com/articles/s41...

I am excited to share our new preprint on the CAGE complex, a mysterious hollow protein complex that I first saw years ago while surveying Tetrahymena ciliary lysate www.biorxiv.org/content/10.1... #cilia #protistsonsky 🧬🧪

Be our neighbour !

Are you interested on how regenerating tissues transit between stages? Am sharing here our work showing that during #Xenopus tail regeneration, tissue stiffening activates a Piezo1-Yap1 mechanosensitive cascade to allow wounded epithelia to transit into regenerative states!

Which city is the best for Cytoskeleton research? Dresden? Barcelona? Cambridge ? Noooo ... you all know its Paris, right? 😎 Registering to the annual meeting on Friday 14th of November is now open: pcd2025.sciencesconf.org Keynote speeches by @carter-lab.bsky.social and Verena Ruprecht !

How is developmental speed regulated ? 🪰 Happy to share my PhD story from Schweisguth Lab @devstempasteur.bsky.social. Here we show that cellular NAD+ availability and redox constrain developmental speed in the fly eye. www.biorxiv.org/content/10.1... A big thanks to everyone involved!

Beautiful #Ediacaran fossil light on the E surface at Mistaken Point 🤩

Tidepooling in Japan 🐚🦀

A molecular-resolution look into the near-native architecture of the spinach chloroplast🌱. This one was a long time in the oven, but we're happy to finally share our "version of record". What long-standing debates did we settle? Check back for a short thread🧵 on Monday. #TeamTomo #PlantScience 🧪🧶🧬🔬🌾

We are hiring a postdoc in bacterial genomics and evolution. research.pasteur.fr/wp-content/u...

Only single cell sequencing of the all these post docs will reveal why

Striking and frightening 😒 "They found multiple instances of insecticide-resistance variants in this malaria vector, although most of these weren’t shared with museum specimens collected as recently as 1967, suggesting rapid emergence" www.science.org/doi/10.1126/...

Do you want to listen to me ramble about Pasteur's Image Analysis Hub (research.pasteur.fr/en/team/imag...)? Let's meet online next Monday. I will present how we work, and what we have learned in delivering bioimage analysis support in the past 7 years.

Looks like I am late to this party but have exciting news. I’ve been awarded an ERC Starting Grant to study #XtrmCells! Thankful to @erc.europa.eus for this opportunity, and to my collaborators, mentors, and group for their support. Looking forward to exploring the mechanics of these cells!

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

In another exciting development our new preprint is online: www.biorxiv.org/cgi/content/... This is the work of my brilliant graduate student Katerina Kourkoulou in collaboration with Maggie Liu and Arnold Mathijssen. Here is a video of the subject of our study:

Happy to share our new study @ijmonod.bsky.social and @mpi-scienceoflight.bsky.social with C. Duclut and J. Prost. on forces generated by active fluid transport in epithelia and their role in tissue dynamics. Congrats to Huiqiong Wu, G. Arkowitz and R. Chilupuri! www.biorxiv.org/content/10.1...

Are digits modified fins, or evolutionary innovations? Read how we tackled this old question from a new angle🧪 A story with @chasebolt.bsky.social, @homeobox.bsky.social and myself, coordinated by @denisduboule.bsky.social from @college-de-france.fr and published in @nature.com today! #InHoxWeTrust

If you are interested in the latest advances in Imaging Cell Dynamics, check out the 2026 @jcellsci.bsky.social Meeting. These small meetings are a terrific way to meet key people in the field and get feedback on your own work. Highly recommended! www.biologists.com/meetings/jcs...

Epithelial crowding drives membrane depolarisation by ENaC/Na+ entry which triggers rapid volume loss, piezo activation and live cell extrusion. Importantly, low intracellular ATP primes cells for live extrusion by preventing the restoring of mb polarisation. www.nature.com/articles/s41...

My review of the evidence (morphological, embryological and molecular) for the deuterostomes clade is now available. www.annualreviews.org/content/jour...

Registration deadline for @embo.org workshop EvoChromo extended until September 30. meetings.embo.org/event/24-evo...

Similar huge trend at last round of @erc.europa.eu grant application. @ec.europa.eu must adapt to this trend!

Hybridization and introgression are major evolutionary processes. Since the 1940s, the prevailing view has been that they shape plants far more than animals. In our new study (www.science.org/doi/10.1126/... ), we find the opposite: animals exchange genes more, and for longer, than plants

Check out our latest work on chromatin evolution by @crisnava.bsky.social and @seanamontgomery.bsky.social. Building on our study of histone mark conservation (www.nature.com/articles/s41...), we now explore whether these same marks define similar chromatin states across eukaryotes.
