People working with #protists and #fungi might be interested to hear that we in this study sequenced 13.4 mio. eukaryotic rRNA operons from 450 representative samples. #ProtistsOnSky #Metabarcoding

seems that protists were way ahead of us with the invention of the circular economy 😊 great to hear of 'holobionts' again 👍 #SymnioSky #MicroSky #ProtistsOnSky

One more week to apply to this PhD position on working out an endosymbiosis relationship in a protist. Please share widely to prospective PhD student #protistsonsky

Hey folks, we (the School of Life Sciences at Arizona State University) are looking for an Assistant Teaching Professor in microbiology and immunology. Please pass this on to anyone you think might be interested, or check it out if you are interested yourself! apply.interfolio.com/176994

The cold water tintinnid ciliate Parafavella elegans & some diatoms from the Chukchi Sea last summer- almost the end of the Arctic samples....

Lab’s first paper is out!! We show the first structures of #Asgard #chromatin by #cryo-EM 🧬❄️ Asgard histones form closed and open hypernucleosomes. Closed are conserved across #Archaea, while open resemble eukaryotic H3–H4 octasomes and are Asgard-specific. More here: www.cell.com/molecular-ce...

A couple of days left to submit your abstract for the upcoming EMBO/EMBL Symposium on the Molecular Basis of Symbiosis ! Great line up of speakers :) #ProtistsOnSky #SymbioSky

This work shines because of @zjmaggiexu.bsky.social passion for these cells. She built it all—the cultures, transcriptomes, analyses, modeling and collaborations—from scratch. I can’t begin to express how brilliant and hard-working a scientist she is (and she's 👀 for postdocs!). So proud of her 🥲

How do cells adapt morphology to function? In a 🔥 preprint by @zjmaggiexu.bsky.social , with @dudinlab.bsky.social and @amyweeks.bsky.social , we identify a self-organizing single-cell morphology circuit that optimizes the feeding trap structure of the suctorian P. collini. 🧵 tinyurl.com/4k8nv926

Wow! Remarkably complete story on the logic of phenotypic plasticity in a predatory protist - congrats @cellraiser.bsky.social et al!

It is a collaboration between my lab (Uppsala U) and the labs of @dudinlab.bsky.social (Geneva U) and @filiphusnik.bsky.social (OIST). More info and how to apply here: uu.varbi.com/en/what:job/....

We are looking for a PhD student to work on an exciting plastid endosymbiosis in microbial eukaryotes. This position involves sampling, exciting microscopy such as CARDFISH, ExM and FIBSEM, single-cell transcriptomics and more. #protistsonsky 1/2

🚨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

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

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

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!
