A phylogenetic classification of diatoms (Bacillariophyta) Diatoms are known for their extraordinary species richness, cornerstone roles in aquatic ecosystems, and immense contributions to the global cycling of carbon, oxygen, and silica. For nearly 2 centur....

Our phylogenetic classification of >400 diatom genera is now published in Journal of Phycology.

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:

Why did consciousness evolve at all? A superb special issue of @royalsocietypublishing.org brings together experts across disciplines to explore the functions of consciousness and why it emerged in some species but not others. @tecumsehfitch.bsky.social royalsocietypublishing.org/rstb/issue/3...

Comparative Genomics of Unicellular Eukaryotes (San Feliu, Spain):
Abstract submission is open, with a short deadline! comparativegenomics2026.com

Join us as we explore the most diverse, surprising, and still largely uncharted branches of the eukaryotic tree.

The day is finally here!! On behalf of all the co-organizers the Comparative Genomics of Unicellular Eukaryotes website is open.

C. flexa might not yet be a genetic model, but it is now at least a calendar model, which counts for something. I think.

Are you very busy but still want to learn what Aphelids are and why they are important to understand the evolution of Fungi?
Then check out our “Quick guide” on Aphelids published in collaboration with @deemteam.bsky.social, Sergey and Guifré. #protistsonsky
doi.org/10.1016/j.cu...

With our old friends Sergey, Luis and Guifré, we have published a minireview in @currentbiology.bsky.social about aphelids, the sister group to fungi, including why we think they are not fungi but, nevertheless, key to understand early fungal evolution.

So happy to announce our new preprint, “A geothermal amoeba sets a new upper temperature limit for eukaryotes.” We cultured a novel amoeba from Lassen Volcanic NP (CA, USA) that divides at 63°C (145°F) 🔥 - a new record for euk growth!

How do cells adapt morphology to function? In a 🔥 preprint by @zjmaggiexu.bsky.social , with @dudinlab.bsky.social and @amyweeks.bsky.social , we identify a self-organizing single-cell morphology circuit that optimizes the feeding trap structure of the suctorian P. collini. 🧵 tinyurl.com/4k8nv926

Adenine DNA methylation associated with transcriptionally permissive chromatin is widespread across eukaryotes - Nature Genetics Long-read sequencing in 18 unicellular eukaryotes reveals that 6mA is widespread across eukaryotes and is enriched at transcriptionally permissive regions, which are also marked by H3K4me3.

Out today, our take on 6-methyladenine #6mA evolution in Eukaryotes @natgenet.nature.com. We asked a simple question, is really DNA 6mA common across the eukaryotes? The answer is "yes" if you're a unicellular eukaryote 🦠, not so if you're multicellular 🐝🌱🍄. www.nature.com/articles/s41... 1/9

Wow! Congrats @fmikus.bsky.social @gautamdey.bsky.social @dudinlab.bsky.social and all authors! Superb resource!
