🚨Our collaboration with @centriolelab.bsky.social & @gautamdey.bsky.social is out today in @cp-cell.bsky.social We show that #Expansion #Microscopy is a broad-spectrum modality for Euks, enabling 3D phenotypic maps rooted to phylogeny. #ProtistsOnSky #SciComm #SciSky www.cell.com/cell/fulltex...

In French - Virginie on Swiss radio! 🎙️ She talks about our latest collab with @dudinlab.bsky.social and @gautamdey.bsky.social #UExM #ProtistsOnSky

Exciting day for the lab: our 1rst paper is officially out in @currentbiology.bsky.social 🥳 Wonderful collaboration wt @gautamdey.bsky.social showing how Cryo-ExM achieves consistent immunostaining in diverse diatoms, from the lab and the natural environment 1/n #ProtistsOnSky tinyurl.com/2zxaund7

Had a fun two weeks in Heidelberg visiting in the @floravincent.bsky.social and @gautamdey.bsky.social labs! Expanding diatoms and their evil little parasites was peak Halloween vibes 🎃 @embl.org #ExM #diatoms

Soraya Zwahlen, a PhD student in the Vincent @floravincent.bsky.social group @embl.org, was our speaker at the DB seminar this week. She discussed a cell-ecosystem approach to studying marine microbial interactions under pollutant stress. #MarineMicrobiology #MicrobialInteractions

#ProtistsOnSky the elephant in the (protist)room...

One is the best EMBO/EMBL symposium is coming up and it’s going to be AWESOME. Save the date !

Wowww!!! Amazing news @messorensen.bsky.social 🤩 Huge congrats & so excited for your lab at @cemess.bsky.social! #protistsonsky www.univie.ac.at/en/news/deta...

Check out our new paper on adopting a trait-based framework for protist diversity! We make the case for a unified protist trait database, how to build it, and how it could transform research on protist ecology and evolution. #protistsonsky

📢 Recruitment for the EMBL International PhD Programme is officially open! At EMBL, we train young scientists to become skilled and creative future leaders in academia and other sectors. Join us and get a head start on your career in life sciences! bit.ly/47mmiFF

A small piece with PhD student @sorayazwahlen.bsky.social and Wiebe Kooistra on why we think Chaetoceros is an emerging model system for phytoplankton research, ranging from its ecological role, to unique cellular features and - of course - its many symbiotic interactions in the marine microbiome.

Last week, we started to collect samples from high-altitude Alpine lakes for the ERC-funded #CAPSOLUTION project! Throughout July and August, we will study the diversity of #viruses, #bacteria, and #protists in these extreme environments. #HorizonEU @erc.europa.eu @mpimarinemicrobio.bsky.social

Our home base for the first week was Lake Gossenköllesee at 2416 m elevation. The research station (Univ. of Innsbruck) sheltered us during an unexpected snowstorm in July. See pubmed.ncbi.nlm.nih.gov/33436089 for viruses from this lake! #CAPSOLUTION @mpimarinemicrobio.bsky.social @erc.europa.eu

On #OceansDay2025, EMBL’s Science Education and Public Engagement (SEPE) Team joined forces with the German-American Institute (DAI) to bring the underwater world closer to families in Heidelberg. Learn more: www.embl.org/news/lab-mat...

So good to reconnect with the adrenaline of field work. My guilty pleasure as a PI is to keep this happening to make sure you never go too far from the initial Pasión. Mesocosm experiments simulating impact of marine heat waves on marine microbial interactions in Vigo. @embl.org #UnivVigo

Such a pleasure to be co-organising the #Latsis Symposium this year with Guillermina ! Thanks to all the speakers & sponsors. And all our teams members who helped make this a reality. It just felt right. #Science #WildCells #ProtistsOnSky #Cell #Biology #Biophysics #Behaviour

The Marine Research Centre (CIM) at the University of Vigo, Spain, and EMBL join forces to study how to curb red tides and anticipate the effects of marine heatwaves. The CELLBLOOM project will advance scientific understanding of current global changes in the ocean. www.embl.org/news/lab-mat...

A huge thx to @vibtrainconf.bsky.social for this #MLD8 full of diatom geeks. Such a beautiful community & really phenomenal science. @serenaflori.bsky.social could present her latest preprint & I updated the diatom folks on how we make Chaetoceros a good model for phytoplankton symbiosis research !

#MLD8 is underway in sunny Ghent! Kicked off with exciting breakthroughs in diatom biology and new tools for molecular studies. Great to reconnect and dive into cell biology, ecophysiology, genomics & biotech. Tiny but mighty! 🌊 #DiatomResearch #BlueBiotech Find out more: vibbio.tech/4kRX2L7

A new day starts at #MLD8 in Ghent 🐑🐑

Stunning views of diverse diatom cell types generated with cryo-em, with a new workflow developed by Serena Flori @serenaflori.bsky.social at EMBL with @floravincent.bsky.social. Being able to see inside these organisms with this resolution is so incredibly cool. #MLD8

The origin of the #MLD8 logo explained. We welcome >200 participants (from 26 countries) in the wonderful Bijloke concert hall for an update on diatom biology.

Fantastic, very cool!!

90% of you probably don’t need to read this. But maybe some of you are curious & 10% will feel seen. Or a little less alone. This isn’t about seeking sympathy. It’s about sharing something hard to say out loud; partly to heal, partly in case someone needs to hear it too. (1/3) tinyurl.com/DudinO

Wowww

Absolutely stunning work !! huge congratulations to the authors! The images are breathtaking, and I'm so excited to see @marinelap.bsky.social Cryo-ExM protocol working beautifully on diatoms.

The future is now! Super cool

Look at those #DIATOMS LOOK AT THESE #Microtubules Congrats to the team Long-live #UExM #Expansion #Microscopy

wow 🌟 what an exuberant fireworks display for #ProtistsOnSky 👏

CryoExM is such an exciting method, great to see it being used in so many wonderful ways!

Beautiful expansion microscopy of diatoms. Check out those cool #CO2 - fixing pyrenoids! The interesting shapes are likely formed by the #PyShell around the Rubisco. Congrats @serenaflori.bsky.social @floravincent.bsky.social and the whole @embltrec.bsky.social plankton team! 🧪🌾🌍🔬

This is glorious! And diatoms are as weird as ever!

Mind-blowingly amazing!!! Kudos to everyone involved!!!

Wow!

Expansion microscopy of diatoms 🤩 Congrats @floravincent.bsky.social et al! Excited to try it on parasite infected diatoms 😈

🌎 Diatoms are now more accessible for modern and comparative cell biology research. The Vincent @floravincent.bsky.social and Dey @gautamdey.bsky.social groups @embl.org show how cryo-ExM enables the scalable, cost-effective imaging of diatom ultrastructure.

Just lovely work from @floravincent.bsky.social and team, one of @embl.org’s faculty that is really focused on bring molecular biology into understand our planet its biological environment

Forgot to add the # 🤦‍♀️ Here's for #MicroSky #ProtistsOnSky #Diatoms #ExM #plankton #SymbioSky #Microbiology

Excited to share the lab's 1rst preprint! Rapid high-res immunofluorescence is now possible in cultured & environmental diatoms thanks to 4-fold expansion microscopy. A step-change for comparative cell biology in one of the most important phytoplankton groups on the planet 🥳 tinyurl.com/m9s5su7s 1/2

✨ This week at the DB Unit seminar, Laurine Planat, a PhD student in the Vincent group @floravincent.bsky.social @embl.org, shared insights on diatom-bacteria interactions during climate change #marinebiology #diatoms #climatechange

Many amoebae incorporate diatoms in their shells, but Cylindrifflugia bacillariarum is the master. Third and fourth pics are close views of the glue that holds it all together. #ProtistsonSky #Amoebae #Peatlands
