Coupes drastiques du budget de la recherche + durcissement des règles d’attribution des financements ANR «Allez à l’ERC!» qu’ils disent, mais l’ERC saturée prend des mesures pour limiter les candidatures #deadend#recherchefrançaise Une petition semble vaine mais il faut commencer quelque part 👉

We warmly congratulate Robbie #Loewith on receiving an @erc.europa.eu Advanced Grant 2025 : a well-deserved recognition of his exceptional research and scientific impact 👏 @mocel.bsky.social @sciencesunige.bsky.social www.unige.ch/recherche/en...

New preprint! In collaboration with the Steinmetz Lab at PSI we report cryo-EM structures of microtubules at up to 1.9 Å (!) resolution & in different nucleotide state mimics, suggesting a mechanism for lattice-induced GTP hydrolysis and why it leads to catastrophe: tinyurl.com/7cjrf863

Is there a size limit for cells ? How can cells replicate inside the architecture of their environment? Why do cells self-destroy ? This 15-minute movie vimeo.com/1173229237 shows our 2026 edition of the Living Architectures project at the @museeorsay.bsky.social

Excited to share our new preprint! 🧬❄️ by brilliant @mdreimann.bsky.social and great collaborators! Using cryo-ET&EM, we reveal archaeal chromatin in a near-native state: variable-beads-on-a-string fibers shaped by growth phase and histone composition #ArchaeaSky www.biorxiv.org/content/10.6...

🥉 Third Prize Winner! 🥉 Congrats to PhD student @anthonyrabate.bsky.social (Université Lyon 1) for this stunning shot, "A tulip field in the drosophila testis"! 🌷 These are young elongating spermatids captured via expansion microscopy. 🔬✨ #FluorescenceFriday #Cilia2027

The CNRS has opened a Junior Professor Chair (CPJ) call in Parasitology, and the Microbiologie Fondamentale et Pathogénicité (MFP, Bordeaux) laboratory is among the potential host institutions. More information: www.insb.cnrs.fr/fr/cnrsinfo/... #Parasitology #Protozoology #ResearchJobs #CNRS

Our paper "Gene ancestries reveal diverse microbial associations during eukaryogenesis.” is finally out in Nature. Eukaryogenesis was likely a gradual process shaped by multiple microbial partners and virus-mediated gene transfer, rather than a single binary symbiosis. doi.org/10.1038/s415...

📢 We are looking for a Junior Group Leader to join us at @institutcurie.bsky.social! Having joined the department just over a year ago, I can honestly say that it is an exceptionally stimulating and supportive scientific environment, filled with outstanding colleagues — all in the heart of Paris.

Better vitrification = better cryo-ET. We've opened an RFA for two-year grants to advance vitrification techniques for biological samples—welcoming applications from researchers in heat transfer, cryogenics, and materials science. Apply here: bit.ly/4uip6eJ

We are looking for a new colleague to join us in Galway. The position is in Biochemistry and if research focus lines up we hope the successful person will join us in the Centre for Chromosome biology (chromosome.ie). Reach out if you are interested in applying! tinyurl.com/2jy4rj3r

Big congratulations to our winners: Smilla-Maria Koy (1st), Chandrama Ghosh (2nd), and Anthony Rabaté (3rd)! Check out their breath-taking micrographs and the rest of the Top 15 entries in the stunning poster attached. The future of cilia research looks beautiful. 📸 #Cilia2027

Two great talks to start day 3 of #JCSimaging. Jonas Reis talked about phaseFLUX, a new version of MINFLUX. Virginie Hamel presented work on UExM. Amazing images and showing that cryofixation improves the preservation to better resolve subcellular structures.

Happy #FluorescenceFriday all! 🔬 First Chlamydomonas experiment/U-ExM image from my lab. Haven't worked on these beautiful little cells since grad school 😍 #memories #cilia

How do cells communicate? They use Sms1 ! 🙂 More seriously, Sms1 is the scaffold of the pheromone-MAPK signalling cascade in fission yeast, which @borissieber.bsky.social et al discovered. Have a look at the paper 👇 @biology-unige.bsky.social

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...

@mhakala.bsky.social shows that HRS forms bidimensional condensates onto endosomal membranes to flatten clathrin/ESCRT-0, an observation unexplained since the 2000s. Thx to Kukulski lab, @stefvass.bsky.social @colomlab.bsky.social @kaksonen.bsky.social @mishakudryashev.bsky.social rdcu.be/fihKk

#EMBOExM is in full swing! On day two of the EMBO course 'Ultrascructure expansion microscopy: from cells to tissue' participants are learning hands-on how to prepare samples, perform gelation and immunostaining and how to map cellular biodiversity with expansion microscopy 🔬🧫

Day 2 of the EMBO U-ExM Workshop at EMBL Heidelberg #EMBOExM. Gels are ready and expanding nicely! We also had a lively poster session and inspiring talks from @sabsalon.bsky.social and @gautamdey.bsky.social. A very engaged group, great to see such thoughtful discussions around expansion microscopy

Day 1 of the EMBO U-ExM Workshop at EMBL Heidelberg #EMBOExM Great to see this workshop finally kicking off, engaged discussions, talks, and our first gelation and expansion already underway. Many thanks to our sponsors for their support! Looking forward to the next days !!

We are looking for outstanding scientists to develop ambitious research programs in molecular and cellular biology, with special interest in multidisciplinary projects and computational biology.More info: www.i2bc.paris-saclay.fr #MolecularBiology #CellBiology #ComputationalBiology #TeamLeaders#I2BC

New online: Microtubules in the axon are GDP bound but adopt a stable GTP-like expanded state

@cellarchlab.com The soundtrack was missing 😂

While XL/MS provided several candidates for microtubule binding proteins, the subciliary localization was further verified by @marinebrunet.bsky.social w U-ExM. This combo identified several new microtubule binding proteins including DNAJB6, which is abundant in the transition zone and axoneme

It’s done!! Molecular architecture of the ciliary base in mammalian multiciliated cells! A study 13 years in the making 👴, thanks to collab with @stearnslab.bsky.social + @centriolelab.bsky.social & visionary work by @computingcaitie.bsky.social, who integrated native #cryoET with #XLMS & #UExM 🧪🧶🧬🔬

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...
