Cell Bio 2023-An ASCB|EMBO Meeting Network, learn, and collaborate with top cell biologists from around the globe.

🚨Hear, hear, fellow microbial cell biologists!🚨
🦠 Bacterial and Archaeal Cell Biology will be represented again at this year’s CELL BIO (ASCB-EMBO) meeting! The deadline to be considered for a talk in our Minisymposium is June 9. Help us spread the word!

One of biggest mysteries in biology: how did complex eukaryotic cells evolve from simple microbes? ~1.8 billion years ago, an archaeal cell likely merged with a bacterium to form the first eukaryotic cell, but can we ever find direct evidence of this transformative event? 🦠 🚶‍♂️

Wow! Radler et al. doi.org/10.1101/2025... These are #asgardarchaea with what? Pseudopodia? Should we call them archaepodia analogously to archaellum? Mindblowing anyway!

Honored to present our research on archaeal toxin-antitoxin systems at the International Thermophiles Congress 2025—great discussions and inspiring science all around! #Thermophiles2025 #Microbiology @IndiaDST @ANRFIndia @bose_institute

Caught in the act! 📸 Negative-stained TEM of the hot and acidic life of Sulfolobus acidocaldarius, snapped mid-division while waving hi with its pilli. 😁

De novo designed bright, hyperstable rhodamine binders for fluorescence microscopy De novo protein design has emerged as a powerful strategy with the promise to create new tools. The practical performance of designed fluorophore binders, however, has remained far from meeting fluore...

Preprint drop! 🚨 Rhobin-tag your proteins and watch Saci glow at high temps! 🔥 Bright, photostable, live-cell imaging made possible with JF dyes. Huge thanks to @samjlord.bsky.social @acharlesorszag.bsky.social @mullinslab.bsky.social and Bo Huang lab at UCSF.😊

A promotional card introducing a speaker for the Michael Sars Symposium 2025. It has a blue background, on the left-hand side, a portrait of a man with short dark hair and a dark blue patterned shirt. On the right-hand side, text reads: MICHAEL SARS SYMPOSIUM 2025 Decoding signals and unveiling architectures, from molecules to organisms Multi-scale imaging of an Asgard archaeon illuminates the origin of the eukaryotic cytoskeleton Jingwei Xu ETH Zürich June 6, 2025, Media City Bergen At the bottom, the logo of the Michael Sars Centre, of the University of Bergen, of EMBL preceded by the mention 'Partner of', and the hashtag MSS2025.

We are excited to present Jingwei Xu @xujwet.bsky.social from @ethz.ch for #MSS2025 🤩 His work focuses on the evolutionary origins of cytoskeletons, using advanced microscopy techniques to reveal the cell biology of Asgard archaea 🦠 Only one week left to sign up! ➡️ tinyurl.com/yc4jxdvz

Mark in your calendars! The Molecular Biology of Archaea meeting (MBoA) 2026!

Join us in Cambridge, UK, from 6–10 July 2026 for the only international meeting dedicated to Archaea.

Preprint alert! I’m publishing my last paper from my postdoc work on archaeal cell biology, with @mullinslab.bsky.social, @archaellum.bsky.social, @samjlord.bsky.social, @marleenvw.bsky.social, @arghya93.bsky.social, and more great folks (thread below with more details)

🚨 Preprint alert!
Our new work is out now 🤩
Turns out even spherical archaeal cells have a clever way of organizing and segregating their chromosomes - using a bipolar SegAB structure!
Deeply grateful to have worked with @acharlesorszag.bsky.social @samjlord.bsky.social @mullinslab.bsky.social

Asgard archaea have actin - but what about microtubules? Where do they come from? 🧐 Our new paper www.cell.com/cell/fulltex... by @xujwet.bsky.social & @florianwollweber.bsky.social, in collaboration with the Schleper & Wieczorek labs, describes tiny Asgard microtubules! #TeamTomo #ArchaeaSky 1/6

Sulfo-buddies going splitsville! 😆

Great to see that Department of Science and Technology, Government of India showcased our work on VapBC4 toxin-antitoxin system of Sulfolobus.

"Ants solving a geometric problem and it's amazing."

This is a great example of 'emergent phenomenon':
- None of the ants understand the problem they're solving.
- None of them can see the whole shape.
- A series of small decisions or rules add up to something with a new layer of complexity.

Last day at the @aglab-2024.bsky.social , Bose Institute, and its an emotional one- feeling sad to leave as well as excited for what lies ahead. Grateful for all the memories here and looking forward to joining the Mullins Lab at UCSF to do wonderful science with his team..
