This is a compilation of world’s fastest single cell organisms - enjoy this buffet of rare delightful protists with mind bending speeds. 🧪
Lovely piece on five model organisms for the origin of animal multicellularity and on the community who studies them. It was a pleasure to make a small contribution.
What could be more exciting than watching Euplotes scurry around under the microscope? How about adding some raptorial predation by supergiant cannibal cells?

Very happy to share our new paper where we develop CRISPR-Cas9 genome editing in our favorite unicellular relative of animals, Corallochytrium limacisporum! With @sebasn1.bsky.social @multicellgenome.bsky.social Elena and Claudio.

I had an excellent time at Choanocon in Paris meeting old friends (some who I had never met in 3D!) and making new ones.
Congratulations to @thibautbrunet.bsky.social and team for some excellent organising. There was a squeaky pig, there were baguettes, there were weird bugs, the people were happy.
The End! Thanks all for joining us🙌🏻🙌🏻 Hope everyone enjoy this amazing week💚💚
#ChoanoCon2025
Nice to see Margarita presenting our work with
@beaplab.bsky.social and @luisjagago.bsky.social on Maop2, the first #Magnificent8 missing unicellular lineages closely related to animals we got in culture! #animalorigins #diversity #holozoans #protistsOnSky
The day began with lab introductions!!
Session 1: Cell biology & multicellularity
🔷David Booth (UCSF):Ecological perspectives on choanoflagellate cell differentiation
🔷 @pawelburkhardt.bsky.social t: Choanoflagellates & the origin of neurons Neuronal origins
🔷 @agathechaigne.bsky.social : Cytoplasmic bridges in S. rosetta

Expansion microscopy micrograph of the choanoflagellate Choanoeca flexa, vaguely evocative of a cactus. Red = tubulin, green = actin, blue = DNA
Same with yellow = lipids (BODIPY)
A dream come true: the first expansion microscopy images of C. flexa 🤩 Generated by Mylan & Uzuki who learned from the best (@hiralshah.bsky.social @gautamdey.bsky.social @dudinlab.bsky.social). We will learn so much from these!
My group is hiring a new Postdoc to work on gene regulation and chromatin in Nematostella. Please RT!

📢Excited to share our new paper in Nature Physics

Asgard archaea have actin - but what about microtubules? Where do they come from? 🧐 Our new paper www.cell.com/cell/fulltex... by @xujwet.bsky.social & @florianwollweber.bsky.social, in collaboration with the Schleper & Wieczorek labs, describes tiny Asgard microtubules! #TeamTomo #ArchaeaSky 1/6
1/46 Hey folks, we have a new paper out on the MuLTEE. Strap in and I’ll tell you the story of how this “little paper on polyploidy” turned into the most data rich paper our lab has produced, largely thanks to the leadership and work ethic of @kaitong25.bsky.social.

Excited to announce the 10th "Choanoflagellates & Friends Workshop" over May 20-22 in our own Institut Pasteur in Paris: 2025choanocon.wordpress.com Registrations open til March 15, abstract til March 5. Pre-conference event for students/postdocs on 19/05. Plenty of slots for selected talks/posters!
Happy to share our paper’s final version on the evolution, structure, and membrane binding / remodeling of Asgard ESCRT-III proteins! And my first 🦋 post! www.science.org/doi/10.1126/...
A clam with a spring attached to the shell. The spring has a magnet placed above a sensor.
Hardly new info, but BSky should know:
Warsaw's water quality is monitored by eight clams with magnets attached to their shells. If contamination in the water causes the clams to close, the magnets trigger an alarm and shut off the city's water supply.
Thank you, little guardian molluscs.

The world is full of crazy and sad news, but here is a protein that localizes to only one of the two flagella
Very excited that the lab's first paper is out! We showed that in stem cells, Aurora B controls abscission dynamics by regulating microtubules stability and MCAK recruitment. Very happy with this streamlined version of our 2024 preprint.
