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).

MicroSEA (Microbial Sea Eukaryotes) course is a one-week, field-based summer school to train early-career researchers in the diversity, ecology, and single-cell biology of marine protists. MicroSEA course integrates lectures, field sampling, and lab-based practicals in advanced techniques, such as flow cytometry, microscopy, culturing, and molecular analysis.

The main objectives of MicroSEA course are: 

Fostering a deep understanding of marine protist diversity, ecology and biology;
Providing hands-on training in advanced single-cell methods that are not commonly available in university programs;
Building participants' confidence in designing and conducting research projects from field to data analysis;
Promoting international collaborations and peer networking among students and speakers/trainers.
The course will take place at the Station Biologique de Roscoff - SBR (France) - 7th to 12th of June, 2026 (arrival on the 6th, departure on the 13th).

20 participants will be selected, including 10 from EuroMarine member institutes.

It shows schematics of a symbiotic sea anemone and a bleached sea anemone. On the right-hand side, the card is titled 'Stinging cells - poisonous harpoons to feed and fight'. That card has tentacles catching small shrimps, and a close-up of cnidocytes, the stinging cells of jellyfish and sea anemones.

Evolution of monoamine reception and its role in cellular contractility.

How do #sponges coordinate their bodies despite lacking neurons and true muscles?

We show that sponges use monoamines to control water flow in their canals β€” reminiscent of how adrenaline regulates blood vessels.

As Fran was nice enough to highlight this, I thought I'd put up a brief thread. 3 in 10 proteins that our cells make are either embedded in membranes (ion channels, adhesion molecules, etc.) or secreted (insulin, antibodies). They move through the secretory pathway.
