Extensive array of endogenous giant viral elements in a polar alga shows dynamic transcriptional response to abiotic stress Schultz et al. show that polar algae harbor extensive endogenous giant virus elements that are transcriptionally active, stress responsive, and integrated into host regulatory networks, highlighting v...

Excited to share our lab's new paper in Current Biology featuring MS student Sydney Schultz's work. We show that a polar alga carries large amount of giant viral DNA in its genome, and many of the viral genes respond to stress - with implications for host adaptation.

This is super cool!! This is a kind of ciliate called a suctoria (this one happens to be Acineta sp.) and it’s sucking up the contents of this egg! You can see it consuming the mush on the left hand side of the ‘martini glass’ (timelapse)

So I pleased to announce the conceptual spawn of FigTree: PearTree (acronym still to be finalised). If you want to dive right in it is hosted as a web app here: artic-network.github.io/peartree (click the “Example...” button for immediate candy and then click every button you can find).

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:
