*Recruiting new group leaders*

The @lmcb-ucl.bsky.social at University College London are looking for outstanding candidates to sponsor for career development fellowships. Fellows would then be assessed for tenured positions at the end of the fellowship term.

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)

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.

How does the piRNA pathway solve the self vs. non-self problem? 🧬

Since piRNAs come from single-stranded RNA, how does the cell choose the right ones? For years, "piRNA clusters" were seen as THE privileged source. But are they really special and earmarked for biogenesis? (1/19)

The origin of eukaryotic cells continues to be one of the greatest mysteries in biology.

EMBL Grenoble is excited to welcome Florian Wollweber, who will use cutting-edge imaging techniques to study Asgard archaea β€” microbes closely related to our earliest ancestors. πŸ¦ πŸ”¬
