Do you need a very tough as well as strong material? Look at this study using a mussel to define their properties and leading to a inspired biomaterial with this properties! www.science.org/doi/10.1126/...

The @ec.europa.eu backs GENCODE with 19 million euros, helping long-term sustainability of one of the most important and widely used biodata resources in the world. GENCODE has a long history at the CRG, a project that still involves @rodericguigo.bsky.social Full story: www.crg.eu/en/news/euro...

Happy #FluorescenceFriday. Single immune cell migration is fascinating. But these cells can also behave like a coordinated collective, like 🐝 from a hive. I captured some embryonic myeloid cells (🔴) displaying swarming behaviour in a migrating ectoderm cell sheet (🔵), like neutrophils in our body!

A few days late, but I realised I have now been a PI for 20 years. Wow. How time has flown… I wrote the post below in 2016, after 10 years of running a lab, about the miracle of surviving startup. quantixed.org/2016/09/26/t...

We have a new branch in the family tree of animals: Atreyea- a previously unrecognized lineage among the closest unicell relatives of animals. Led by @konsmitsi.bsky.social & @freejakoba.bsky.social together with a fantastic team of collaborators. 🔗 papers.ssrn.com/sol3/papers.... #protistsOnSky

I feel so fascinated everytime I see this Sorokin drawings Sorokin, JCS, 1968😍😍

Some exciting news: I'm joining the University of Lausanne @unil.bsky.social @dbc-unil.bsky.social as an Assistant Professor next month 🎉 My group will work on context-aware deep learning for protein structure, interaction & design. Postdoc and PhD openings coming soon - keep an eye out!

Can light build centrosome-like activity? 💡🔬 Yes! We introduce LISA (Light-Induced Spindle Assembly), now in @emboreports.org. By clustering Aurora A with optogenetics, we build centrosome-like activity that nucleates microtubules and rescues spindle defects after centrosome loss. shorturl.at/9h3VQ

Biochemical diversity of tubulin: Carsten Janke, Zdenek Lansky and collaborators screen 46 microtubule-associated proteins to reveal their distinct affinities to tubulin isotypes and posttranslational modifications link.springer.com/article/10.1...

Essential paper if you want to study open/closed mitosis in non model organisms!!! Super cool!👇👇😍

Millions of beating cilia keep airways clean. At the base of each is the transition zone (TZ), a gate that controls which proteins enter and leave. In our paper out today in Science, we used cryo-FIB-ET to image the TZ inside human airway cells www.science.org/doi/10.1126/...

I am looking for a lab manager for my group that I will be starting at the @fmiscience.bsky.social in February! We will use in situ structural biology to investigate dynamic ciliary processes. More info here —> bsky.app/profile/comp... #cilia #teamtomo #proteomics #protistsky

Off to Lausanne to spend four days thinking about one of the most fascinating organelles ;) #EMBOCentrosomes at EPFL: centrioles, PCM, cilia So if you wanna chat about the centriole architecture, UExM, you will find me around! #postdoclife #cellbiology

Dear #CryoEM and #Microtubule enthusiasts, I’m thrilled to have been part of this exciting journey: www.biorxiv.org/content/10.6... We discovered and characterized a manchette-like microtubule machinery in Xenopus spermatids, likely involved in sperm reshaping and membrane reorganization. (1/3)

An inducible multiciliated cell line resolves proteome dynamics and identifies CDK7 as a conserved regulator. From Camille Boutin @camboutin.bsky.social, Laurent Kodjabachian and colleagues: rupress.org/jcb/article/... 📕 Part of #Centrosomes and #Cilia 2026: rupress.org/jcb/collecti...

Very happy to see our Nature Reviews Molecular Cell Biology Roadmap out! A fantastic collective effort, led by Carsten Janke and Zdenek Lansky, together with an amazing group of colleagues, and sparked by inspiring discussions at the Fondation des Treilles. www.nature.com/articles/s41...

Excited to share our newest work! We asked whether RNA molecules need to be in a specific place in the cell to do their job. We found that a single RNA must reach the midbody, the structure that pinches two dividing cells apart, for cell division to finish efficiently. 🧵⬇️

Very happy to see this #MechanoGolgi story out (and in full open access, thanks to @upf.edu). Thanks a lot to everyone who contributed and helped make this possible, and, hopefully, more to come! rupress.org/jcb/article/...

Cosmic horror at the sub-cellular scale 🌠🐙 Mutant mouse Mx1 (green) forming tentacle-like structures crawling through a genomic portal (pink; DNA). Like Cthulhu breaching the barriers between realms... Years later, these geometries remain unexplained. 🔬: Joe McKellar

Good method to avoiding loosing the fluorescence of your FPs in expansion!👇

From tissue-clearing to invisibility there are only a few steps! www.biorxiv.org/content/10.6...

🚨 Want to start your lab in Marseille on a broad neuronal/brain development theme? There's an exciting tenure track opportunity at @inp-marseille.bsky.social and others Marseille institutes! Check more details here: neuro-marseille.org/en/blog/juni... or contact me if you have any question

I am delighted to share the final version of our latest study, led by the extraordinary PhD student Jiaoqi Cheng. We developed CenSegNet, a generalist AI framework for large-scale mapping of centrosome phenotypes at both spatial and single-cell resolution. (1/6) www.nature.com/articles/s41...

I am starting my lab at the University of Geneva next January! Incredibly excited to soon be joining the MOCEL department as an Asst. Professor. The lab will use evolutionary cell biology to study chromosomes, centromeres & speciation 🧬🔬🌱 Intrigued, want to join or collaborate? 🔗 helsenlab.org

Not everyday a friend is able to define a new organelle!!! If you like membrane compartimentalization and are interested in how cells responde to stress in membrane tension, check this out!👇👇 Congrats to Elda and co!! www.biorxiv.org/content/10.6...

Yeeeeey Big congrats @centriolelab.bsky.social !!!!!!! 😍

Honored and delighted to be elected an EMBO Member. A huge thank you to our amazing team, this recognition wouldn't be possible without you. Perfect day to celebrate together during our lab outing! 🎉 - Virginie

As you might imagine, as someone who studies science and works on metrics, I have some thoughts on qed myself. I fully agree that the messaging can be described as tone-deaf and problematic. I don’t think it had to be. ripplingideas.org/2026/06/26/t...

Happy to finally share that I will be starting my independent group at the @fmiscience.bsky.social in Feb 2027 in a vibrant new environment. We will use integrative in situ structural cell biology methods to investigate ciliary structure and dynamics in several model (and non-model 👀) systems!!

And now it's out! Happy that PNAS selected for the cover this SEM image snapped by @samjlord.bsky.social, one of the most evocative visualizations of Euplotes that I have ever encountered. www.pnas.org/doi/10.1073/... Stay tuned for what is shaping up to be some fascinating follow-up in the lab...

Very excited that our discovery of Sms1 as the #MAPK #scaffold of fission yeast mating has just been published in @natcomms.nature.com! @biology-unige.bsky.social www.nature.com/articles/s41...

🥳🥳🥳

Wow. Super cool tool:)

📣 New preprint from our lab! How does the cell place septins to actin or microtubules (MTs) with septins being ~10-100 times less than actin/tubulin? We found a phosphorylation switch controlled by GSK3 that makes that call 🧫🔬🧵 biorxiv.org/content/10.64898/2026.05.06.723191v1 1/7
