New preprint out! Using ~75k environmental OTUs + 77 fossil calibrations, we reconstructed a Proterozoic timeline of eukaryote evolution. Our results show crown eukaryotes were already diversifying >1.6 Ga, long before the first undisputed fossils (~1.05 Ga). 🔗 DOI: www.biorxiv.org/content/10.6...

Save the date! The next instalment of Comparative Genomics of Unicellular Eukaryotes is a GO! Join us next year for a programme of talks, posters, ECR/networking activities. Website and registration details to follow in the coming weeks. See you October 5-10 2026 in beautiful San Feliu!!

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

Now completely published :) Really proud of this paper led with Karla at @cstairs.bsky.social lab. doi.org/10.1093/isme...

For some three billion years, unicellular organisms ruled Earth. Then, around one billion years ago, a new chapter of life began go.nature.com/3JyRV4S

New lab pre-print up! "Twelve species of human parasites make up half the literature on microbial eukaryotes" doi.org/10.1101/2025... We (led by UG Joanna Lepper and with @hbrappap.bsky.social) quantified all mentions of protist species in the scientific literature 🧵 #protistsonsky #microsky

Check out our recent publication on breviate protists and their microbial communities. In this study, led by PhD student Karla and postdoc Julie, we found that breviate growth under anoxia might be dependent on the metabolic capabilities of the prokaryotes they live with. doi.org/10.1093/isme...

Attention ancient environmental DNA folks. In our recent preprint, we provide coordinates of microbial-like regions (contaminated or evolutionary conserved or convergent) for 4,294 eukaryotic reference genomes.

Looking at bioinformaticians’ profiles these days, you'd think everyone has decades of experience in cutting-edge single-cell and AI-driven bioinformatics. But something’s missing… 👇

Winter break reading 🍄 Protists are still the best, but fungi are a close second!

I am looking for an ERC-funded postdoc to work on spatial proteomics of microalgae (red algae and glaucophytes). The ideal candidate will have experience with mass spec and data analysis (R), but above all a keen interest in broad eukaryote evolution and protists #protistsonsky (1/2)

Are you or do you know someone interested in symbiosis research? Anaeramoeba is an exciting organism to explore symbiosis in a low-oxygen environment. Less than a week (December 6) to apply for the PhD position in my group! uu.varbi.com/en/what:job/... Please share widely!

Please share! Applications due Dec 15th for a starting date in Sep 2025.

Women are under-represented at senior levels in #academia globally, & across all #science 🧪 disciplines, as shown by these "scissor-shaped curves" ✂️ So how can we ever achieve #gender #equality? We discuss various strategies in this #Cell Commentary #WomeninSTEM www.cell.com/cell/fulltex... 🧵 1/

Excited to share “Bin Chicken”, substantially improving genome recovery through rational metagenomic assembly. Applied to public 🌍 metagenomes, it recovered 24,000 novel species 🦠, including 6 novel phyla. doi.org/10.1101/2024... @wwood @rhysnewell @CMR_QUT 🧵1/6

First post!! Does anyone in Europe have an axenic or monoxenic culture of Stentor, Blepharisma or Spirostomum they would be willing to share? Please DM me :) #protists #ciliates

I put together a 'protists and friends' starter pack! For anyone interested in hearing about current research spanning diverse topics microbial eukaryotic (ie protist++) biology. This list is super incomplete so please tag/comment folks and I'll add! go.bsky.app/HQhnxbC #protistsonsky 🦠🧪

When not working on getting genomes of awesome protists, I try to watch and film the tiny encounters of the microbial world 🦠🔬 youtu.be/do0uR9QaFI0?...

Happy Christmas, Have a great holiday season! 🎄

"We need to support those who have the necessary knowledge to isolate and culture protists from the environment and to train new generations of scientists who could find this field of research attractive...so they are ready to take over and lead the protist culturing renaissance." #ProtistsOnSky
