We have wondered what a complex archaeal cell might look like ever since 2014. It’s been a long road (and the journey is far from over), but it’s a good time to pause for breath and look. These Asgard archaeal cells are a surprise! And that is the joy of being a cell biologist.

I am beyond excited to share that my postdoc project @szndohrn.bsky.social and the @arnonelab.bsky.social is now available in #ScienceAdvances @science.org. www.science.org/doi/10.1126/...

Diatoms – microscopic algae found almost everywhere there’s water – make up ~25% of Earth’s annual oxygen production.🌎 EMBL researchers have now found a way to easily reveal their inner structures by combining cryo-fixation with ultrastructural expansion microscopy 🔬 www.cell.com/current-biol...

In their Review, Olivier Mercey, @marinebrunet.bsky.social, Paul Guichard & Virginie Hamel @centriolelab.bsky.social highlight advances in microscopy that have significantly deepened our understanding of centriolar & ciliary structure & function. journals.biologists.com/jcs/article/... #OpenAccess

🎉New Paper Drop🎉 We just uploaded our latest findings on bioRxiv! We report the identification of the limits of microtubule self-repair and how microtubule integrity is maintained under mechanical load. Congratulations @bucklingmt.bsky.social www.biorxiv.org/content/10.1...

Two back-to-back stories on mitosis led by my incredible postdoc @krunovuk.bsky.social at @institutrb.bsky.social, in which we challenge the gliding model of CENP-E-driven chromosome congression! Today in @natcomms.nature.com doi.org/10.1038/s414... doi.org/10.1038/s414...

Cryo-Flow : when science freezes and flows ❄️ After turning her thesis on tuberculosis into a rap, Yaëlle Wormser aka Lady Pipette, doctoral student at the Institut Pasteur, is back with a new track — Cryo-Flow — a song that turns Cryo-Electron Microscopy (Cryo-EM) into rhythm & rhyme. @pasteur.fr

Perspective from Richard McIntosh describing the history of research on #microtubule polymerization in terms of the ideas, technologies, and observations that have emerged as countless researchers have studied the dynamics of these essential cytoskeletal polymers. rupress.org/jcb/article/...

We hire! The CytoMorpho Lab is looking for an engineer with a background in cell and molecular biology to join our team in Paris. This is a 18-month contract position, but we're open to exploring long-term opportunities. More details here: cytomorpholab.com/index.php/jo...

Happy to share that our paper on Tau- Microtubule interaction is now published in Nature Physics!🥳 We show that Tau isn’t just a microtubule stabiliser - it promotes removal of defects in the microtubule lattice. Congratulations @subhambiswas.bsky.social! www.nature.com/articles/s41...

After 5 amazing years @pilhoferlab.bsky.social I'm starting my lab @embl.org Grenoble this November embl.org/wollweber We'll image Asgard archaea and many other strange microbes ( #archaeasky, #protistsonsky..) to understand eukaryogenesis First job ad: #teamtomo scientist!🔬❄️ tinyurl.com/2rdu2ze6

Our paper on Lymphostatin is now out (rdcu.be/etk2v). It shows #cryoEM structures of this huge virulence factor revealing amazing domain reorganisations. Very enjoyable collaborating with the Stevens Lab in Edinburgh and the Boersch Lab in Jena to see how it gets into cells. @uni-wuerzburg.de 🧪❄️

🚨 New preprint! Using U-ExM + in situ cryo-ET, we show how C2CD3 builds an in-to-out radial architecture connecting the distal centriole lumen to its appendages. Great collab with @cellarchlab.com @chgenoud.bsky.social @stearnslab.bsky.social 🙌. #TeamTomo #UExM www.biorxiv.org/content/10.1...

I think it's important to reach out to your own community and explain what the funding cuts mean in practice.

Unique opportunity to join the CytoMorpho Lab (in Paris ❤️) as a postdoc to work on the self-organization and polarization of reconstituted networks made of microtubules, motors and actin filaments in vitro. Experience required. Please Repost 🙏 thanks !

Je pense qu’ici je prêche des convaincus, mais ce rappel est toujours bon, parce que je ne comprends toujours pas pourquoi nos politiques et officiels utilisent encore cette plate-forme de propagande hostile à la France pour leur communication… ça me dépasse.
