Condensates are powerful ways to break symmetry and cells do remarkable things with them. Here we show that in a multinucleate fungus, a condensate regulates translation of a cyclin and a formin in distinct locations.

Sooo happy to share our new paper in @nature.com “CLCC1 promotes hepatic neutral lipid flux and nuclear pore complex assembly.” A terrific collaboration with @arrudalab.bsky.social, led by co–first authors Alyssa Mathiowetz and Emily Maymand.

Cells come in many shapes and sizes, with diverse physiological functions. But how do #organelles and their interaction networks remodel during #differentiation of stem cells into different cell types? Here’s what we discovered about neuronal differentiation: 1/13
Thrilled to share our latest study, led by @reikatei.bsky.social, in @natchembio.nature.com! We began by asking a simple question—how do cells know if they have too much of a lipid in a particular membrane, and how do they respond to rectify this imbalance?

I've been waiting for this Titeca et al. story from Anne-Claude Gavin's lab to come out: A systematic, comprehensive analysis of lipid transfer protein cargo selection, a truly massive undertaking. What a time to work in lipid biology. Cool stuff every few days.

This opening statement made me actually open and read the paper. You all should, too. It's a wonderful piece of work. Thought-provoking in the best sense. It may very well be that Yamuna & team have found a proxy measurement for local metabolic activity. Which would be a game changer.
New work describes our efforts to achieve CRISPR editing of the mitochondrial genome.

Joe Shen’s and Zaza Gelashvili’s work on the role of the ER in nuclear membrane mechanotransduction finally came out in a journal!
And another Asgard paper. Cells in motion! Wow! www.biorxiv.org/content/10.1...
Preprint alert! It is my great pleasure to announce the first manuscript from the lab, a story that started @gmivienna.bsky.social and was mainly accomplished by the intrepid @gesahoffmann.bsky.social at @mpi-mp-potsdam.bsky.social. A brief thread with our findings

New preprint from the lab!!🎉
We show that Asgard archaea ESCRT-III proteins can trigger membrane fission and reveal its molecular mechanism, offering clues to how these cells may have built internal compartments. But do these organisms even have these compartments?
www.biorxiv.org/content/10.1...
And the saga continues! Our collaborative work with outstanding Justin Korfhage & Thomas Melia’s lab in PNAS shows that ATG2A transfers triglycerides and does so bidirectionally! An exciting twist in our understanding of lipid transport.
Definitely worth a deep read:

How do new centromeres evolve while staying compatible with the division machinery?
Discover it in our new Nature paper! We show centromeres transition gradually via a mix of drift, selection, and sex, reaching new states that still work with the kinetochore.

Is it a flagellate? A tiny ball with tentacles? Contamination in my ciliate culture? NEW SUPERGROUP OF EUKARYOTES? Yes to all 4! Meet Solarion - just out in #Nature doi.org/10.1038/s415... Huge congrats to Marek Valt, Cepicka Lab & the star team! Very happy to be part of this project. #ProtistsOnSky
Great work from the lab of @jojdavies.bsky.social

Congratulations!
Launching celldynamicslab.com, the homepage of our new group at EPFL working on cell fragmentation, membrane and cortex mechanics, FLIM imaging, and microfluidics tools. MSc/PhD or postdocs interested in quantitative cell biology are welcome to reach out. We're also hiring a lab manager in 2026!
And just when you thought things were settling down, the enigmatic Asgard archaea have another surprise in store! Cell cycle/life cycle stage-specific internal compartments with almost no eukaryote-derived clues as to how they might function.
Beautiful tomography and microscopy - congrats all 🤩
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.

How is epigenetic information inherited? We found that CDCA7 proteins are critical players in the inheritance of DNA methylation at CG sites in plants, and this is true both in the lab and in the wild. How does this work? 🧵👇

Lipid imaging on the cover of @nature.com! Great times for lipid cell biology indeed. And a fantastic recognition of all the hard work by the team, especially Juan M. Iglesias-Artola and Kristin Böhlig (who made the cover). Link to article: www.nature.com/articles/s41...
