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

Love #protists? Then you'd love this! Beautiful collection of hand-drawn critters represented here at the Oxford-Japan symposium on ethological dynamics in diorama environments sites.google.com/view/oxford-... #ciliates #testateamoeba #diatoms

I am excited to share our new preprint on the CAGE complex, a mysterious hollow protein complex that I first saw years ago while surveying Tetrahymena ciliary lysate www.biorxiv.org/content/10.1... #cilia #protistsonsky 🧬🧪

Some little circus performers. #protistsonsky

Excited to share our third heterotrophic #Paulinella culture from Haida Gwaii, Canada! :) #ProtistsOnSky

New preprint 🌊🫶 "A diverse community constitutes global coccolithophore calcium carbonate stocks" Three large coccolithophores together hold about half of the global CaCO₃ stock! G. huxleyi <10% ➡️ climate models need to include this broader diversity! 📄 doi.org/10.1101/2025... #protistsonsky

We have several open positions in my group, funded from the ERC Grant on the Early Sequestered Germline of Fungi. We search broadly for applicants at both PhD and master-level, with a dedicated interest in fungal evolutionary biology. Please forward and RT! Find the positions here: su.varbi.com

found this lil guy in a sand sample recently 😍🦑 #protistsonsky

New short paper from our lab @currentbiology.bsky.social, in which we discover of a new mode of cell motility for choanoflagellates: flagellar gliding. www.cell.com/current-biol... - A 🧵

#FossilFriday an SEM image of a 1.4 billion year old #acritarch. The first image shows you the surface topography. The other images are pseudo x-rays showing the internal structures. I figured out how to do these tiny x rays on Weds, it's going to be really useful in future. #geology #paleontology

Our 2nd heterotrophic #Paulinella culture! Really proud of this one. After days at the microscope picking cells, I finally got it growing happily :) #protistsonsky

Did you know tiny algae can "skate" within Arctic sea ice? ⛸️ Our new study in @pnas.org reveals the secret life of ice diatoms: they are actively gliding to navigate the ice! This adds a new dimension to the sea ice ecosystem, revealing an active, dynamic ecological niche. @prakashlab.bsky.social

New paper is out! We have studied the cute tiny Discocelia plataet sp. n. to obtain the first molecular data of the order Discocelida and clarify its cell structure. All this for a better understanding of the evolution of Cercozoa. onlinelibrary.wiley.com/doi/epdf/10....

What could be more exciting than watching Euplotes scurry around under the microscope? How about adding some raptorial predation by supergiant cannibal cells? www.biorxiv.org/content/10.1... Video by Vittorio Boscaro. 1/n

Complex behaviour is not limited to animals! Here we map the entire spectrum of waveforms dynamics on a quadriflagellate single cell with 4x 70um (!) #cilia, to a low dimensional behavioural manifold with surprising structure! #protistsonsky All revealed in our new preprint doi.org/10.1101/2025...

It started as a master thesis project by Markus Hiltunen, and ended up in this publication in Science. What a fun project to work on! Thanks Markus - and all other coauthors, too, for a great team work! www.science.org/doi/10.1126/...

The first paper from my PhD is out now! doi.org/10.1111/jeu.... We describe a new photosynthetic #Paulinella species from a brackish beach in British Columbia 🇨🇦 Big thanks to the co-authors Maia Palka and @alive-in-the-ocean.bsky.social, and my supervisor @fburki.bsky.social #protistsonsky

We’ve come a long way to sample on Haida Gwaii (BC). Inspired by this paper, we have traveled to the same place in the hope that we are going to find again these Paulinella species #protistsonsky www.cambridge.org/core/journal...

In our ongoing saga of description of new protists, we are happy to introduce Multisulcus malaysiensis, a deep-branching heterolobosean that forms highly unusual multiflagellated cells with multiple ventral grooves. Great work by @kristina-prokina.bsky.social onlinelibrary.wiley.com/doi/epdf/10....

This sampling campaign for heterotrophic Paulinella involves digging lots of holes on the beach #protistsonsky @thealgaeman.bsky.social on the photo

We have a postdoc opening for a protistologist with biophysics inclinations to join our @hfspo.bsky.social project! (focus will be on characterising the morphology, ultrastructure and behaviour of excavates) #protistsonsky Apply by Sept 17th (RTs appreciated!) jobs.exeter.ac.uk/hrpr_webrecr...
