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...

Interesting cancer grand challenges just announced. Funders looking for interdisciplinary & international teams. I'm an outsider, but fascinated that some of them have clear eco-evo cell-population dynamical component.

Super cool thread about a fascinating new study from @wcratcliff.bsky.social and his team!
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.

I just posted "Some Experiments Work, and Some Don't."
It features this new paper from Paul Rainey's group, along with a *failed* experiment that Paul Sniegowski and I ran in the 1990s trying to test the same idea.

Legitmately thrilled to share our latest work, in which @fernpizza.bsky.social solved an experimental challenge in plasmid biology as old as the field: measuring how plasmids compete and evolve within individual cells!

So, we are also opening an account here. Same idea as in twitter: we will explain our work as well as the work of others in the field of multicellularity, animal origins, and #protists. #ProtistsOnSky We focus a lot on unicellular relatives of animals, mostly #Ichthyosporea & #Filasterea.
