Congratulations to Gautam Dey (EMBL) and Omaya Dudin (University of Geneva) for being awarded the EMBO Gold Medal 2026 in recognition of their outstanding contributions to the #LifeSciences in Europe! 🧪 https://www.embo.org/press-releases/embo-gold-medal-2026-awarded-to-gautam-dey-and-omaya-dudin/

⚡ Our paper is now out in @natphys.nature.com ! This version now includes a detailed molecular characterisation of the optogenetic perturbations, new insights on the relevance of tricellular junctions for tissue morphology, and beautiful light-sheet timelapses. 🔬 www.nature.com/articles/s41...

Multinucleate cells challenge deeply-held assumptions about complexity, ecological success and evolution. Postdoc extraordinaire and gifted writer @mrosjac.bsky.social tackles this subject with aplomb - tell us what you think! www.sciencedirect.com/science/arti... @currentbiology.bsky.social

💫 Our paper is now published at @natcellbio.nature.com! So excited about this work done during my PhD at @embl.org in the group of @nicolettapetridou.bsky.social along with our great collaborators! 🐟🎉

🌊 Exciting #PhDPosition in #PlanktonEcology at the University of Koblenz, Germany! Work on marine protists with a mix of 🔬 wet lab and 💻 bioinformatics in a 3-year, 60% position. 📅 Apply by 20 May 2026 Please repost/share 🙌 Link: tinyurl.com/yu27knau #Protists #MicrobialEcology #PhD #Ecology

Our ExM Atlas of eukaryotes is moving along with more and more images coming in - some featured in nature last month! Culture we’re provided by @ccapoban.bsky.social & Julius Lukeš during visits last year www.nature.com/immersive/d4...

Last few places left! www.ccap.ac.uk/index.php/algaculture2026/

The next of our Special Guest Presenters on CCAP’s online training course later this month is Dr Hiral Shah. Dr Shah's talk is entitled "Exploring cytoskeletal diversity across eukaryotes using expansion microscopy" See the link below for course details 👇 www.ccap.ac.uk/index.php/algaculture2026/

Attending Protistology Open? Check out @nicolecoots.bsky.social & I's ISOP-sponsored symposium "The Symbiotic Continuum across the Tree of Life" (April 20th @ 11 AM)! We have an amazing lineup of speakers including Ondřej Pomahač, @mixotrophe.bsky.social, & Gillian Gile #ProtistsOnSky #Symbiosis

I am extremely excited that my first first-author paper from my PhD is finally out 😆!! We developed a new CLEM workflow to measure lipid densities at the nanoscale. So if you are into lipids and super-resolution imaging approaches, this one is for you: www.nature.com/articles/s41...

It’s 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.nature.com/articles/s41...

Excited to announce I’m starting a new lab at @gmivienna.bsky.social (Vienna BioCentre) in Sept 2026 We study how carbon fixation is inherited and maintained in algae using cryo-ET, imaging, environmental sampling&more Looking for people who want to build the lab together, get in touch! #teamtomo

And the best parts about it - it's not over! More and more data is coming out from #TREC and the science will be fantastic to engage with. And my truck? Well it's an #EMBL facility open to the scientific community. If you're interested have a look www.embl.org/groups/mobil... or reach out

@embl.org at its best: collaborative, open, transformative, and just the right amount of crazy. Dreaming of mechanistic cell biology *in the natural environment*? Dream no more, rent the AML. www.biorxiv.org/content/10.6... www.youtube.com/watch?v=jepb... #WeFreezeOnTheBeach #ProtistsOnSky 🦠🌍🧪

Excited to share our new review in @dev-journal.bsky.social on tissue phase transitions during development! @karengrace12.bsky.social @nicolettapetridou.bsky.social 🔗 doi.org/10.1242/dev....

The origin of eukaryotic cells continues to be one of the greatest mysteries in biology. EMBL Grenoble is excited to welcome Florian Wollweber, who will use cutting-edge imaging techniques to study Asgard archaea — microbes closely related to our earliest ancestors. 🦠🔬 www.embl.org/news/people-...

It was a really fun couple of weeks in the lab ! I also very much enjoyed being in full handle of the #Zeiss 3Dsim scope provided generously for us to explore the various samples.

Over the last two weeks the Dudin Lab expanded two-fold and it’s been a blast! We are hosting a group of amazing visitors that stopped by with their own species and samples to get started with expansion microscopy. It was a ton of fun, very much looking forward to pictures to come ❤️ #ExpandThemAll

🔬🔦Our Imaging spotlight from @hiralshah.bsky.social & team highlights their U-ExM atlas of planktonic eukaryotes, including details on how you can explore this wonderful resource. Plus, check out Hiral’s top tips on getting started with expansion microscopy. focalplane.biologists.com/2026/01/20/i...

On this day in 2021, I landed in a snowy, lockdown-silenced Heidelberg to start my lab. 5 years later we are a force to reckon with in our field, and the first generation are striking out on their own. I couldn’t be more proud, & grateful to them and our wonderful collaborators around the world 🌍 🧪

Another #notTHECover unfortunately. But this gorgeous, Tron-like vibe, drawn by the amazing @munafomarzia.bsky.social for our recent #ExM work with @gautamdey.bsky.social & @centriolelab.bsky.social will still be printed out in the lab. Read here: www.cell.com/cell/fulltex...

We hope that integrating models with data will unlock new predictive capacity for mixotrophs--and beyond. Huge thanks to Ginger for scouting us, and to collaborators @suleles.bsky.social, @gautamdey.bsky.social, @fmikus.bsky.social, Julian Jacobs, and Kevin Archibald for building skills & ideas!

We’re excited to announce the opening of the Geneva Expansion Microscopy Facility (GenExM)! GenExM is a full-service U-ExM platform (U-ExM, Cryo-ExM, iU-ExM), delivering nanoscale imaging. Led by Dr. Olivier Mercey, GenExM welcomes academic & industrial collaborations. 👉 www.unige.ch/genexm/

Preprint alert 🔔 Organosulfur compounds support carbon and energy metabolism in chemosynthetic symbiosis. Happy to see this cool collaboration with @organosulfur.bsky.social and others out 🥳

So proud to watch Jana turn a side quest into an entire research programme. Couldn’t imagine a more well-deserved outcome. 😍 The mighty yeast reveals what we believe are general principles of centromere evolution! Behind the curtain: communities.springernature.com/posts/counti... #MEvoSky 🧪🌎

Our attempt to give multinucleate cells the spotlight they deserve (seriously, they’re everywhere), led by the fearless @mrosjac.bsky.social and with @Markus Ganter doi.org/10.32942/X2M... We’d love your feedback while this goes through the peer review process! #MicroEvoSky #ProtistsonSky 🧪🌏

How do new centromeres evolve while staying compatible with the division machinery? Discover it in our new Nature paper! We show centromeres transition gradually via a mix of drift, selection, and sex, reaching new states that still work with the kinetochore. 👉 doi.org/10.1038/s41586-025-09779-1

So happy to announce our new preprint, “A geothermal amoeba sets a new upper temperature limit for eukaryotes.” We cultured a novel amoeba from Lassen Volcanic NP (CA, USA) that divides at 63°C (145°F) 🔥 - a new record for euk growth! #protistsonsky 🧵
