By controlling how cells align, we show that living nematic tissues can be programmed to generate forces and fold into predictable 3D shapes.
A new platform for tissue engineering and the design of smart active materials! ๐ซ

We offer a PostDoc position for a fully funded project on lipid-encoded #lipidtime protein quality-control checkpoints at the Golgi: great collaborators, excellent working & living conditions & benchspace with a view ;) Please share and repost!
Tardigrades resist heavy DNA damage by actively repairing such lesions & expressing DNA-protective proteins. Yet, they are not immortal. How & why do they die? @morielab.bsky.social now shows that their Achilles' heel is DNA replication: duplicating your DNA... will kill you doi.org/10.1111/febs...
I am excited to share our most recent work collaborating with @centriolelab.bsky.social and @stearnslab.bsky.social to look at the ciliary base of mammalian multiciliated cells w/ cryo-ET, XL/MS, and U-ExM www.biorxiv.org/content/10.6...
When DNA damage responders are not only that: @MorieLAB.bsky.social shows that, without ATM, one master kinase responding to DNA damage, the Golgi is markedly deployed. ATM phosphorylates Golgi substrates to limit Golgi extension, which matters for Golgi cargo maturation: doi.org/10.64898/202...
Itโs incredibly hard to study lipids in biological membranes on the nanoscale. You need near-perfect information on both membrane ultrastructure and lipid density. Lipid-CLEM, now out in @natcellbio.nature.com brought to you by @mathilda95.bsky.social changes that:

www.biorxiv.org/content/10.6... Amazing work by Kris and gang! For the first time we have been able to image division ring components live in Sulfolobus. And guess what - CdvA is asymmetrically inherited.

A new publication in EMBO J by Dr. Jorge Montesinos (@cib-csic.bsky.social) identifies a new mechanism that enables cells to regulate the energy they produce and opens avenues for future research into neurodegenerative and metabolic diseases.

Meanwhile, Spain's massive investment in renewables is paying dividends now: with prices for Spanish industry and consumers low and stable compared with other European economies.

With Eugene Koonin, we propose a concept of โthe selfish ribosomeโ, under which evolution of life is viewed as a ribosomal takeover, where the ribosome evolved to consume most of the cellโs resources, while other cellular componentry ensures the propagation of the ribosome. arxiv.org/abs/2602.23268
Final version @nature.com of our paper describing unconventional multicellular development in a choanoflagellate inhabiting an extreme environment. A ton of new data since the first @biorxivpreprint.bsky.social preprint (which we've kept updating).

Can't miss this amazing study on the ribosome structure of the Haloferax archaeon ๐๐ผ๐๐ผ๐๐ผ!! Congrats to my good friend @diorgeps.bsky.social and all the other ppl involved!!
Congratulations!! ๐๐ผ๐๐ผ๐๐ผ
Great job!! ๐๐ผ๐๐ผ๐๐ผ
Congratulations to all authors!
Hello epithelial mechanics fans!! Iโm Juanma @juanmagararc.bsky.social ๐ I work on cell mechanics (see celldynamicslab.com) and use Flipper-TR FLIM to probe membrane biophysics in cells.
Join me on this tour about Flipper: what it measures, strengths, advice, cool case studies, and cute drawings!

#cellbiologyofeukaryogenesis @sbcf.bsky.social
fantastic start for our Eukaryogenesis meeting with a vivid overview of membrane remodelling systems in Archae!
Today at 17:00 CET - the first #MembraneTrafficking seminar of 2026.
Giovanni DโAngelo (EPFL) and Sean Munro (MRC-LMB), explore protein trafficking, retention, and sorting at the Golgi.
Join us for exciting discussions about the best organelle!

Join us this Thursday (Jan 29) at 5pm CET for the first #MembraneTrafficking seminars of 2026, featuring two outstanding scientists, Giovanni D'Angelo (EPFL) and Sean Munro (@cellbiol-mrclmb.bsky.social), and the shared topic of protein trafficking, retention & sorting at the #Golgi ๐ฅ
A reminder to sign up for the 2026 EMBO archaeal meeting im Cambridge: meetings.embo.org/event/26-arc.... Registration is open. We are looking forward to hosting you!
๐จ Want to know how we demonstrated the importance of sterol-rich membrane microdomains for M. marinum infection?

โจ Big thanks to everyone, especially Cristina Boehm-Bosmani, @soldatilab.bsky.social ! โจ
1. As we recently joined BlueSky, we want to repost this story for all newcomers!
We sat down with @radler92.bsky.social to get more insight into the unique videos from his recent preprint on Promethearchaeota (formerly Asgard archaea).
doi.org/10.1101/2025...
(Videos and info below)
Are you a long-time fan of Archaea, an extremophile-phile, or are you simply curious?
Either way, we have good news.
Weโre delighted to announce the 2026 EMBO Workshop on Archaea, 6โ10 July.
Sign up: meetings.embo.org/event/26-arc...
We look forward to seeing you in Cambridge, UK.
Please repost!
Congrats Omaya!! ๐๐ผ๐๐ผ๐๐ผ๐๐ผ
