We are very excited to share a new resource from our team: spatial subcellular proteome maps in plants! We developed an MS-based method that registers localizations of about 8000 proteins in Arabidopsis roots in a single experiment.

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

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?”
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.

Join us as we explore the most diverse, surprising, and still largely uncharted branches of the eukaryotic tree.
Disc-shaped fossils with concentric grooves scattered through a limestone block.
Image of the apex of the Great Pyramid, taken from the base of the southeast corner. The layers of massive blocks of limestone composing the pyramid are clearly visible. The pyramid is set against a sunny blue sky.
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.

Isadonna Tengganu and Ke Hu develop transfection and ExM protocols for Chromera velia, enabling direct comparisons with its parasitic apicomplexan relative, Toxoplasma gondi.

New preprint out! Using ~75k environmental OTUs + 77 fossil calibrations, we reconstructed a Proterozoic timeline of eukaryote evolution. Our results show crown eukaryotes were already diversifying >1.6 Ga, long before the first undisputed fossils (~1.05 Ga).

Wow! Radler et al. doi.org/10.1101/2025... These are #asgardarchaea with what? Pseudopodia? Should we call them archaepodia analogously to archaellum? Mindblowing anyway!

Daily reminder that you are a better writer and researcher than any generative AI platform around. Your skills are worthy and it takes far more time to clean-up and fact-check the mess some chatbot spits out than to just do it yourself 😘
