Great weekend sampling Sierra Nevada high mountain lakes with friends from the @multicellgenome.bsky.social and @rmassanam.bsky.social labs! Thank you for coming!

I am extremely happy to announce that I have been awarded an @erc.europa.eu ERC Starting Grant to lead the ProtistEye project! We will be diving into the function, architecture, and diversity of eye-like structures across different protists to better understand their evolution. Stay tuned for more!

📣 Good news! 📣 Results of the ERC 2026 Starting Grant call are out! Funding worth a total of €705 million will go to 421 early-career researchers across Europe. Discover who, what and where 👉 link.europa.eu/9M3MmN 🧪 #ERCStG #FrontierResearch #HorizonEurope 🇪🇺 @scienceinnovation.ec.europa.eu

What's that? You wish we had more data on those bizarre dinoflagellates WITH EYES? Have no fear! With @protistwtmostest.bsky.social, Gordon Lax, and @pjkeelinglab.bsky.social, who also have eyes.

Evolution of complex organelles in ocelloid-bearing dinoflagellates

Abstract. Warnowiid dinoflagellates are known for possessing two of the most complex structures known in single cells: multi-projectile nematocysts and the

Apusomonads are the best protists (no discussions allowed🤣). Join Iñaki and his team to describe new “water-elephants”!

Iñaki Ruiz-Trillo@multicellgenome.bsky.social · 2mo ago

Most people have never heard of #apusomonads. Yet these tiny protists occupy an important position in the eukaryotic tree of life. And we know so little about them! We're looking for a Master's student to help uncover their hidden diversity. #ProtistsOnSky 🧵 @ibe-barcelona.bsky.social @prbb.org

In September we will have the pleasure of hosting Karla and @fmikus.bsky.social from the labs of @dudinlab.bsky.social and @gautamdey.bsky.social. If you are around Granada please join us for their talk! They will present ExÂME, an incredible initiative to build a 3D atlas of protists diversity!
