Thrilled to see choanoflagellates can glide! I think this provide further support to the stunning complexity of the unicellular ancestor of animals, as we have been proposing. Congrats @thibautbrunet.bsky.social ! very nice work. #AnimalOrigins #choanos #multicellularity #protistsOnSky

Flagellar gliding in choanoflagellates

Freire-Delgado and Brunet discover a new mode of cell motility in choanoflagellates, the closest relatives of animals. Under mild confinement, choanoflagellate move over surfaces without cell deformat...

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

More on the ancient foundation of animal development. Coyle & King illustrate how core regulatory modules were present in our pre-animal ancestors. The key was not invention, but recycling & new protein interactions. #CellBiology #multicellularity #protistsOnSky

Congrats Haillot & the whole @ulrichtechnau.bsky.social lab! Another brilliant example of how we shouldn't assume simplicity in non-bilaterian animals. Triploblasty’s roots seem to run older than we thought! Nice to see a crosstalk between MAPK, β-catenin & Notch to define identities. #EvoDevo

ulrichtechnau.bsky.social @ulrichtechnau.bsky.social · Aug 29

Finally, the excellent postdoc work of Emmanuel Haillot is out, where he dissected the integration of Wnt, MAPK and Notch signaling in defining mesoderm and endoderm identities in the diploblast Nematostella. Strikingly similar to sea urchins. www.nature.com/articles/s41...

🚀 Watching Núria Ros-Rocher grow from PhD student to independent @cnrs.fr researcher has been a joy. Talent + grit + kindness = 🔥. Huge congrats, Núria—and kudos, Thibaut. And I know this is just the beginning! Can’t wait for the next C. flexa chapters!

Thibaut Brunet @thibautbrunet.bsky.social · Aug 30

A thousand bravos for Núria Ros-Rocher, who just secured a permanent @cnrs.fr researcher position in our lab. These positions are (too) rare but give much-needed job security to young scientists and allow long-term projects. Núria will dive deep into the natural history of C. flexa 🧪🌊 #ProudPI

wow! A huge congratulations to @StevenHaddock & @sonkejo.bsky.social, whose work I have admired for years This book looks absolutely gorgeous and, as a huge fan of #bioluminescenc and #diversity, I'll definitely be getting a copy for the lab. #scicomm

Steve Haddock @stevehaddock.bsky.social · Aug 28

Our science photo book The Radiant Sea is out Sept 2nd!!
30 years of research, 10 years of "we should", and a year of collating pix and writing.
Sönke and I show (mostly for the first time) images of how organisms produce, use, and interact with light in the sea. #bioluminescence #fluorescence 🦑🧪🌊

Her contributions were essential to improve the genomes of our organisms (#ichthyosporeans ), get more information on the evolution of transcription factors, and get amazing data on the evolution of genomic regulation on pre-metazoans. She also supervised 3 master students! #comfuturo #protistsOnsky

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
