Happy to share that our story on the bacterial archaellum was published today in @natmicrobiol.nature.com www.nature.com/articles/s41... Congrats to the authors: @sshamphavi.bsky.social @loumollat.bsky.social @mariejoest.bsky.social Najwa Taib and @sgribaldo.bsky.social

How do cells keep their #actin “highways” stable?🚦 Our paper @PLOS Genetics reveals surprising teamwork (and backup plans!) between tropomyosin isoforms in yeast. #imaging #cytoskeleton #celldivision This work was brilliantly led by @anubhavdhar.bsky.social @bagyasree.bsky.social t.co/RvUrzad5tL

For some three billion years, unicellular organisms ruled Earth. Then, around one billion years ago, a new chapter of life began go.nature.com/3JyRV4S

Thrilled to see our work published in @embojournal.org #asgard #archaea #cytoskeleton #tubulin #FtsZ We sincerely appreciate the constructive peer review and the reviewers’ thoughtful, supportive feedback, which greatly strengthened our work.

🎉🍾Excited to share our #Asgardarchaea #odin #cytoskeleton study published in @embojournal.org Dual FtsZ proteins in Odinarchaeon form distinct filaments shedding light on tubulin/FtsZ evolution. Brilliantly led by @jayantik.bsky.social www.embopress.org/doi/full/10....

This was fun! Folding whole proteomes… looking at tomogram, looking at genomes🤩 lots to discover!🧬🧶

How does evolution shape ancient cellular processes? Our new paper uncovers the mosaic evolution of conserved and diverging endocytic traits in fungi! www.cell.com/current-biol...

Hello microscopy and imaging experts and enthusiasts! We are looking for a staff scientist to join us here in Geneva to work on microscopy and image analysis projects! See the link for the job announcement (in French and in English). Please apply and/or repost! jobs.unige.ch/www/wd_porta...

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...

We’ve uncovered Asgard chromatin structures formed by a Hodarchaeal histone : closed hypernucleosome conserved in archaea and an open form resembling the H3-H4 eukaryotic octasome. Fantastic work by @harshranawat.bsky.social! www.biorxiv.org/content/10.1... #Chromatin #Asgard #Archaea #cryoEM

Preprint: IntAct-U-ExM enables robust, isoform-specific expansion microscopy of actin networks in yeast and mammalian cells. A cool study led by @anubhavdhar.bsky.social in collaboration with Sudarshan and Deepak Nair. www.biorxiv.org/content/10.1...

On this day, 10 years ago, my lab published the @nature.com paper reporting the discovery of the Asgard archaea (Lokiarchaeota at the time), revealing the archaeal nature of eukaryotic cells, and reshaping the Tree of Life. What a ride it has been since then... www.nature.com/articles/nat...

Excited to announce the Molecular Biology of Archaea (MBoA) 2026! Join us in Cambridge, UK, from 6–10 July 2026 for the only international meeting dedicated to Archaea.

Isolated in just 3 years! (previously, 12 years). We obtained two strains from 'Hodarchaeales', proposed to be closest to our archaeal ancestor. Our analysis suggests the ancestor was an anaerobic, syntrophic, peptidotrophic, archaeon with a simple intracellular structure and possible aerotolerance.

First Post! Thrilled to share our lab's first evolutionary cytoskeleton study! We uncover two distinct FtsZ paralogs in Odinarchaeota OdinFtsZ1 forms curved filaments, while OdinFtsZ2 assembles into spiral rings. A glimpse into tubulin evolution! threads👇 #Eukaryogenesis #AsgardArchaea #cytoskeleton
