Clonal-aggregative multicellularity tuned by salinity in a choanoflagellate - Nature The choanoflagellate Choanoeca flexa forms motile and contractile cell monolayers purely clonally, purely aggregatively or through a combination of both processes depending on environmental conditions.

A study in Nature shows that the single-celled form of a tiny, aquatic organism can turn into a multicellular version by three different routes. The discovery adds insight to the possible origins of multicellular life, suggesting a previously unrecognized degree of flexibility. 🧪

We have an ERC funded postdoc position open in the field of structural biology and drug discovery ! We have identified promising inhibitors and their targets in bacteria. Come and help us reveal the structural blueprints for tomorrow’s antibiotics.

I will be recruiting new postdocs with start dates end 2025 - early 2026. If you'd like to work at the Pasteur Institute in the heart of Paris surrounded by amazing scientists, reach out to discuss possible projects on SynBio / Bacterial Immunity!

In Memoriam: Wolfenson, Giannone, and Schwartz recall the life and many contributions of Michael Sheetz, who passed away on January 30, 2025. rupress.org/jcb/article/...

Unique opportunity to join the CytoMorpho Lab (in Paris ❤️) as a postdoc to work on the self-organization and polarization of reconstituted networks made of microtubules, motors and actin filaments in vitro. Experience required.
Please Repost 🙏 thanks !

Exclusive: NIH to terminate hundreds of active research grants Studies that touch on LGBT+ health, gender identity and DEI in the biomedical workforce could be terminated, according to documents obtained by Nature.

NEW: The NIH has begun terminating grants for active projects studying gender identity, DEI, environmental justice, climate change, among other topics.

At least 16 termination letters have already been sent — and hundreds more are coming, people inside NIH tell me.

Science must not be damaged, as it takes too long to repair.
