My last pic of the organizers closing out the inaugural session of the #MicroSEA course, dedicated to hands on single cell methods with micro-eukaryotes. It was an honor and a pleasure to share. Bravo @johandecelle.bsky.social @mjamy.bsky.social @protistwtmostest.bsky.social and other organizers!

Protist lovers: Please apply for a week of rhapsody! Learn by doing: 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. opbc.sciencesconf.org #protistsonsky
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.

In the new preprint, you can see what this enables: Automated #confocal imaging of live communities, EM prep that supports #FIB‑SEM, workflows that integrate single‑cell approaches, on‑site experiments, incubations, and much more.

This really is an excellent paper. It shows that plastid protein import machinery can be inherited through serial transfer, and that we should not expect additional membranes in tertiary plastids. In other words, serial transfers got easier to explain www.sciencedirect.com/science/arti...
