Strain-level diversity of #giantViruses infecting #chlorarachniophyte #algae in the subtropical North Pacific by @fischerlab.bsky.social doi.org/10.1101/2025...

Is it a flagellate? A tiny ball with tentacles? Contamination in my ciliate culture? NEW SUPERGROUP OF EUKARYOTES? Yes to all 4! Meet Solarion - just out in #Nature doi.org/10.1038/s415... Huge congrats to Marek Valt, Cepicka Lab & the star team! Very happy to be part of this project. #ProtistsOnSky

Proud moment to see the first Master student of the team (Lotte Mayer) successfully defend her Master's thesis work digging into viral factories of #giantViruses. A link to part of her work: doi.org/10.1101/2025... @erc.europa.eu @univie.ac.at @cemess.bsky.social @dome-vienna.bsky.social

Last week #ESEB2025 wrapped up. It was a great opportunity to chat with colleagues, hear about great evolutionary research, present the group's work, and be a proud PI of Laura, who did a great job presenting her PhD work! Two years to go until next ESEB! @eseb2025.bsky.social

our paper is online! rdcu.be/exXBX . Who would have thought that some #giantviruses not only have #histones, but even histone variants that make weird #nucleosomes (pdb 9CVT). Fantastic work from Ale Villalta and Chelsea Toner, with Hugo Bisio @molbiolgv.bsky.social and Chantal Abergel

Heat Shock Protein 70 (AKA HSP70) in Mimiviridae and Phycodnaviridae likely originated from horizontal transfer from their protist hosts. By @sfelena.bsky.social & @amaachi.bsky.social doi.org/10.1101/2025... #giantVirus #VirEvol

Out now in its final peer-reviewed form @asm.org's Journal of Virology! doi.org/10.1128/jvi.... @dome-vienna.bsky.social @erc.europa.eu @amersocvirology.bsky.social

New work out! Spearheaded by Lotte, we have developed a single-molecule messenger RNA fluorescence in situ hybridisation (smFISH) protocol for #giantViruses in an #Acanthamoeba host. doi.org/10.1101/2025... 1/4 #ProtistsOnSky #MicroSky @dome-vienna.bsky.social @cemess.bsky.social @erc.europa.eu

by now you probably know that #giantviruses have #histones, but some also have histone variants! Check out our latest preprint on an essential H2B-H2A histone variant in Melbournevirus - a fantastic collaboration with the Abergel Lab, spearheaded by Ale Villalta. www.biorxiv.org/content/10.1...

there is a new #giantvirus in town! and it speaks Finnish! www.biorxiv.org/content/10.1...

behold our paper on Medusavirus nucleosomes. Fantastic work by Chelsea Toner, @nhoitsma.bsky.social, and Sashi Weerawarana This giant virus also encodes a linker histone, more about that in the paper 🧪👩‍🔬 🧵. www.nature.com/articles/s41...

We sequenced some new #genomes! Novel high-quality #amoeba genomes reveal widespread #codonUsage mismatch between #giantViruses and their hosts. doi.org/10.1101/2024... #ProtistsOnSky #MicroSky 🖥️🧬 1/4

Back to the lab after a week of really great research on #virus #evolution in Roscoff! The VEE team was represented by Laura, @danischwarz.bsky.social, @dominikluecking.bsky.social, and myself. (Im)patiently waiting for the next edition of this great meeting! #VirEvol #CJM2024_virEvol

We finally put it together! The first ICTV #Virus #Taxonomy Challenge provides a dataset of thousands of contigs from diverse viruses, asking bioinformaticians to classify them in an automated, reproducible way. See: ictv-vbeg.github.io/ICTV-Taxonom... - tell your bioinformaticians and colleagues!

ZOMBIE CELLS!!! 😱🧟🦠 @janbruewer.bsky.social and colleagues discover how #viruses keep #SAR11 in check and even turn them into zombies! Out now @natureportfolio.bsky.social Nat Comms mpi-bremen.de/en/Zombie-ce... www.nature.com/articles/s41...

Great event last week strengthening research partnerships with colleagues from Kyoto University, particularly with the Ogata lab focusing on giant viruses @cemess.bsky.social @univie.ac.at

New #giantVirus on the block alert! Along with a great team of people lead by @patrickarthofer.bsky.social, Florian Panhölzl, and Matthias Horn, we describe a novel Catovirus infecting the amoeboflagellate #Naegleria @dome-vienna.bsky.social doi.org/10.1038/s414...

Another giant virus with histones y'all. Medusavirus has them all, and even linker histone (maybe?). Check out our latest preprint by the amazing Chelsea Toner and @nhoitsma.bsky.social biorxiv.org/cgi/content/...

Today we farewelled Ruixuan (Ogata lab, Kyoto Univ.) after a month and a half of intense microcopy work! here in the picture featured with the talented Lotte Mayer who supervised and taught him some of our lab techniques!

Welcome to the new Virus Evolution feed. This feed is intended to collect all virus evolution posts. For now, no need to sign up in any way, just tag your posts with #VirEvol (case-insensitive) and your posts will show up here! Like and pin!

Who's planning on going to the MEEHubs meeting for microbial ecology and evolution in January? 🦠🔬🧫 #phagesky #VirEvol #evosky meehubs.org

On our way to the #giantVirus symposium at the Ringberg Castle! #giVirSymp23

Made a new feed for all things giant viruses (aka Nucleocytoviricota at large). Just tag your post with #giantVirus or any of the classes, orders, families, or genera of Nucleocytoviricota (w/wo #, e.g. #Megaviricetes, #Mimiviridae..). Lke and pin it if you like it! #VirEvol bsky.app/profile/did:...

Since I felt a lack of a #Virus #Evolution feed here, I have gone ahead and created one so we can follow posts related to this. For now, no need to sign-up, simply tag your posts with #VirEvol and they will be collected there! bsky.app/profile/did:... 🧪 #MicroSky #phagesky #evolsky

Two open positions! Looking for a #bioinformatics #postdoc and a #laboratory #technician. Interested in joining the team? Check out www.microbial-ecology.net/open-positions

Hey @danirabaiotti.bsky.social, would you mind adding me to the ”What’s Science 🧪” feed?
