Three large coccolithophores together hold about half of the global CaCO₃ stock!

What you're looking at is a brand new protist species! 🤯🔬
Isn't it beautiful?
This image is just a glimpse of what's to come. We can't wait to share our full findings soon, in partnership with Guifré @beaplab.bsky.social @luisjagago.bsky.social. Stay tuned! #NewSpecies #protistsonSky #diversity

How did life get multicellular? Five simple organisms could have the answer Single-celled species that often stick together in colonies have researchers rethinking the origin of animals.

For some three billion years, unicellular organisms ruled Earth. Then, around one billion years ago, a new chapter of life began

Why do some planktonic protists develop a gelatinous matrix? We suggest that this original adaptation is a strategy to cope with ocean oligotrophy: doi.org/10.1111/1462...
Led by @n-llopis-m.bsky.social, and thanks to all co-authors, I'm very happy to finally see it out!

This is so cool!!

And you @maxemilschon.bsky.social ?👀

Haha thanks Felipe! See you in ICOP?

Thank you Max!!

Thanks Iñaki!

ApuRs are rhodopsin channels which evolved independently of the family of channelrhodopsins widespread in other unicellular eukaryotes, expanding on our understanding of the photobiology of heterotrophic flagellates. This is a great collaboration with @labinoue.bsky.social and @bejalab.bsky.social .

First study from the lab is out! We describe ApuRs, a new family of microbial rhodopsins unique from apusomonads. ApuRs represent the first anion-conducting rhodopsin channels that can be controlled by UV light, offering potential as new optogenetic tools. #protistsonsky
