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.

Happy to share a preprint—the last chapter of my dissertation with @mcsymbiont.bsky.social and Co—on what happens when bacterial endosymbionts accumulate huge numbers of pseudogenes during early genome reduction. www.biorxiv.org/content/10.6...
Diagram illustrating early genome erosion during the transition from a free-living Sodalis bacterium to two host-associated endosymbionts inside the long-tailed mealybug. Circular genomes show intact genes in blue and pseudogenes in red, highlighting increased pseudogene accumulation in symbiotic forms. Caption asks: “What are the downstream molecular consequences of early genome erosion?”

I've seen fossils in some remarkable places, but this takes the prize: the benthic foram Nummulites in the base of the Great Pyramid of Giza. These massive blocks were quarried from the Eocene Mokkatam Formation when a relictual population of woolly mammoths still lived on Wrangel Island.

Bacterial tubular networks channel carbohydrates in insect endosymbiosis
Bacteria with an intracellular lifestyle need to feed from inside their host cells. This study shows an adaptation of certain symbiotic bacteria, allowing them to actively retrieve nutrients from the host. High-pressure cryofixation has been combined with volume electron microscopy and in situ high spatial resolution chemical analysis. It reveals a complex bacterial membranous network that increases the exchange interface between the bacteria and host cytosol and maximizes carbohydrate acquisition.
