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!)

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

😻 HUGE NEWS! One of the "Magnificent 8" – key missing lineages for understanding animal origins – is ALIVE in our lab!

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

These parasite-like partners have lost photosynthesis but retained chlorophyll... are they friend or foe?

We sequenced a bunch of understudied flagellates including apusomonads, ancyromonads and one Meteora strain. Here is our version of the eukaryotic tree including them👇 #ProtistsOnSky

Congrats!!

Honored and excited to receive an #ERCCoG grant. Big thanks to my colleagues, former mentors and, most importantly, my amazing lab members. Together, we will be exploring cell type evolution across timescales, from population variation (with @xgrau.bsky.social) to regulatory sequences across phyla.

Radiolaria are known for their elaborate and gorgeous skeletons, found all over our oceans. But what if I tell you that half of their diversity might be naked!?

Fully Funded PhD Opportunity in Evolutionary Biology at the U of Rhode Island. Join us to explore the origin and early evolution of eukaryotes using cutting-edge comparative (meta)genomics and molecular evolution approaches. Applications are due December 15th. Contact me ASAP at laura.eme@uri.edu

Very excited to share that, come January, I will be joining the faculty at @uniofbath.bsky.social as a Lecturer/Assistant Professor! We’ll be studying all things microbiomes, harmful and beneficial host-microbe interactions, and protist diversity and evolution!
