Postdoc opportunity! Join PERKFresh project and explore Perkinsea diversity, ecology & host–parasite interactions in freshwaters 📍 University of Warsaw ⏰ Deadline: 6 Nov 2026 🔗 euraxess.ec.europa.eu/jobs/466845 #protistonsky #postdoc

🎉 Excited to share that Elisabeth Hehenberger and I have been awarded a 🇵🇱🇨🇿 NCN–GAČR grant! We'll explore the diversity, ecology, and interactions of Perkinsea, a fascinating and largely overlooked group of parasitic #protists in #freshwaters. Looking forward to this exciting collaboration!

If you want to read a cool story today, look no further: A billion-year-old bacterial machinery replicates plastid DNA and supports kleptoplastidy #protistsonsky www.biorxiv.org/content/10.6...

Really excited to share our new paper from @ibe-warszawa.bsky.social protist team! 🎉 We dive into protist symbioses and show how these interactions shape ecosystems and have played a key role in the evolution of eukaryotes 🦠

🎉 Big congrats to Alessandro Culicchii, a post-doc in my team! Thanks to the @isme-microbes.bsky.social Mobility Fund, he’s heading to Paris to work with @luciebittner.bsky.social on bacteria and protist association networks in Masurian lakes, using #MicroDivEr data. Good luck! #ProtistOnSky

This really is an excellent paper. It shows that plastid protein import machinery can be inherited through serial transfer, and that we should not expect additional membranes in tertiary plastids. In other words, serial transfers got easier to explain www.sciencedirect.com/science/arti...
