Do #tintinnids dream of electric sheep? 🤯 Here is a single cell capable of building a lorica and living inside it for protection... it also swims, feeds, hunts Can even detect and habituate to mechanical cues! #celllearning #protistsonsky #cilia Read more in our preprint doi.org/10.64898/202...

So happy to share our new paper out now in @natmicrobiol.nature.com! We establish Pirsonia-Coscinodiscus as a model pathosystem and uncover how this tiny parasite infects and kills bloom-forming marine diatoms 🌊🦠 rdcu.be/fuQyF

Plastid endosymbiosis without gene transfer - dinoflagellates can do it #ProtistsOnSky #Kareniaceae #plastids

Recent plastid replacement in Karlodinium ballantinum (Kareniaceae, Dinoflagellata) challenges the paradigms of endosymbiotic gene transfer

Abstract. Plastids, the photosynthetic organelles of eukaryotes, arose via endosymbiosis of cyanobacteria by a eukaryotic host and were subsequently spread

Very excited that the preprint of the main paper of my PhD is now out! We show that Meringosphaera is the first centrohelid with permanent plastids: doi.org/10.64898/202... @zlatogursky.bsky.social, @pjkeelinglab.bsky.social, prof. Rachel A. Foster, and @fburki.bsky.social #protistsonsky

Single cell genomics and fluorescence microscopy suggest a permanent plastid in a marine centrohelid

Photosynthetic organelles (plastids), which originated via primary endosymbiosis between an Archaeplastida ancestor and cyanobacteria, have shaped the Earth's oxygen-rich atmosphere and spread across ...

The uncritical adoption of AI in science is alarming — we urgently need guard rails

Artificial intelligence is rapidly accelerating scientific output, but risks narrowing inquiry, weakening judgement and undermining how scientists are trained.

Excited to say that my new paper with @maxlechte.bsky.social (and others not on bluesky) has come out in @nature.com! Study of sediments, geochemistry and fossils from rocks 1.75 to 1.4 billion years old indicate that the oldest known #eukaryotes were aerobic and benthic! #protists rdcu.be/fjNgL

Early fossil eukaryotes were benthic aerobes

How specific are heritable symbioses? And what can we learn from swapping obligate symbionts across host species? We address this in our latest, led by @inespons.bsky.social & in our collaboration w/ @microbiome.bsky.social 🦠🪲 Out today in @natcomms.nature.com! 1/n www.nature.com/articles/s41...

Check out our latest pre-print of our favourite pets - the breviates. This work was led by Zhezhen Yi in collaboration with @andrewjroger.bsky.social and many others! By studying diverse breviates we were able to see how different metabolic pathways can evolved in response to low-oxygen.
