Final version @nature.com of our paper describing unconventional multicellular development in a choanoflagellate inhabiting an extreme environment. A ton of new data since the first @biorxivpreprint.bsky.social preprint (which we've kept updating).

A brief 🧡 (carried over from the old place)

Have you ever asked yourself, how insect brains represent places? And whether insects do have place cells? Then move to Germany this summer and start your PhD in my lab. We conduct tetrode recordings from bumblebees that freely forage laboratory mazes. 🧠🐝#BeeSpace @erc.europa.eu @neuroethology.org

This is a Nazi move. Stripping people of rights, invalidating their IDs, setting them up for criminalization and imprisonment.

If you don't support trans rights, you support fascism.
