Our Wadjet-II paper by @roisnehamelinf.bsky.social is out in polished form: www.cell.com/structure/fu... With a great preview by @kevincorbett.bsky.social & @amardeeep.bsky.social highlighting the potential of Wadjets: Wadjet—Keeping a watchful eye on circular DNA. www.cell.com/structure/fu...

confession: I often get excited by n=1 results.

Our study on endothelial mechanics made the news! 🤩 Super nice and clear article on our findings and their implications. www.snexplores.org/article/how-...

One of the most exciting discoveries from our lab so far is now online as a preprint! Read a story on how the ParMR and Min systems started to collaborate to create the CorMR cytoskeleton, which now controls cell shape in multicellular cyanobacteria: www.biorxiv.org/content/10.1...

Nice one!! 👏🏼

Elated to have our pre-print now published in @natcomms.nature.com #ArchaeaSky #Microbiology #MEvoSky rdcu.be/euila Our main results stay the same: S. islandicus follows a cell cycle akin to that of some eukaryotes, like the budding yeast, with cellular processes cycling similarly. old🧵cited below👇

How do cells switch on the actin assembly at endocytic sites? How can this on-switch evolve? Check out our new preprint! www.biorxiv.org/content/10.1...

This is great Felix!!! Really happy for you!👏🏼🎉

The @embo.org ESCRT meeting was packed with membrane remodeling from every branch of the tree of life🌳. Some awesome science 🧪 highlights in the next posts 🧵. But a first impression… the venue!! Wow, Caux castle up a cogwheel train, overlooking Lac Léman! Perfect! 🌄 Thank you @rouxlab.bsky.social 🤗

What a fantastic ESCRT meeting, the field is going strong and full of exciting science. Many thanks to @rouxlab.bsky.social @cellarchlab.com @jujumathieu.bsky.social @magromayor.bsky.social @majarad.bsky.social for organising such a a great event

The #MembraneTrafficking online seminars are back this Thursday (June 26th, 5pm CEST). We'll hear from @jnuechel.bsky.social about how to find the right partner for a TANGO, and from Maohan Su about the organizational principles of the Golgi. @ishier.bsky.social @franbottanelli.bsky.social

I'm grateful for the Research Council of Finland for granting me the Academy Research fellowship! After getting over the shock I will soon move back to Finland to start as a group leader at the Institute of Biotechnology @helsinki.fi. Looking for a PhD student soon! www.aka.fi/en/about-us/...

#MembraneTrafficking seminars are back on June 26th at 5pm CEST! Our one and only summer gig feature an early secretory pathway lineup: @jnuechel.bsky.social TANGOing at the ER, and Maohan Su from ‪@yaleschoolofmed.bsky.social on Golgi organization by 3D super-res!

This was a truly exciting talk from Aurelien Roux @rouxlab.bsky.social from Univ. Geneva 👏👏. From his landmark work on membranes to tissues now, the continuing theme is the role of geometry, topology and curvature in morphogenesis. Thanks for visiting us 🤩

Best moments in science are these small events of discovery when you finally get the answer to your question and when what you're doing suddenly makes perfect sense. It's like a mind fusion with the world you're trying to understand. - Dan Hartl

Deep origin of eukaryotes outside Heimdallarchaeia within Asgardarchaeota www.nature.com/articles/s41...

Why are biological membranes asymmetric, with different lipids in the two bilayer leaflets? Discovered in the 70s, lipid asymmetry is linked to many cellular processes, but why the cell needs it is largely unclear. @pavelbarahtjan.bsky.social addresses this question: www.biorxiv.org/content/10.1...

Don't miss the new preprint leaded by one of the postdocs in Unige, Florent Lemaitre ;) T-Cells images at an incredible resolution

It's publication day of my first book: The Tree of Life. The tree of life is a time machine that can take us back 4 billion years to meet our most distant ancestor. It is the magic that lets us tell the origin stories, beginning with this ancient relative, of everything from mushrooms to man.

Beautiful work!! 👏🏼👏🏼

New paper alert! ‼️‼️ Super happy to share that my postdoc paper is finally out! 1/3 We looked at scaling of chromosome separation during anaphase in zebrafish embryos.

Today is a very special day for me: I just started as a permanent CNRS researcher at the Institute of Light and Matter! My research will focus on the physics of biological tissues and in particular the role of activity and anisotropy.🔬 @cnrs.bsky.social
