Join @berasymbionts.bsky.social , @tatsuyanobori.bsky.social and us for a postdoc on the remarkable developmental biology of symbiosis!

Applications are due March 25th 🪲🦠

That smile speaks volumes - as always. Congrats Felix Hol (a lab alum) to be selected for TEDFellows class of 2026. From the swamps at Stanford to villages in Madagascar - I have so many memories with Felix - but his joyful laugh is one that rings again and again. Let's go catch some mosquitoes.

UVs from last week’s sample! Harpacticoida, Cirripedia nauplius (with Asterionellopsis glacialis next to it), Pseudocalanus (with Trieres mobiliensis/regia), not sure - Harpacticoida or Cyclopoida (what do you think?).

NSF-Research Experiences for Undergraduates (REU) at BIOS An REU internship is a great way for U.S. undergraduate students to gain the experience necessary to embark on graduate studies or careers in science.

Come to BIOS this fall for an undergraduate #NSFREU internship!

We’ve extended the deadline!

Fascinating results. Maybe of interest for other types of developmental processes @dudinlab.bsky.social?

Since people are liking the Bocchi colors, I have a whole collection of color palettes on my GitHub: github.com/cxli233/Colo...

You will find the hex code, the preview, and the inspiration for each color palette. I hope some of them will be used.

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).

Society for the Study of Evolution Site description

📢 Now accepting proposals for the Graduate Research Excellence Grants! These provide evolutionary biology research funds for early and advanced Master’s and PhD students. Applicants must be members of SSE. Deadline: May 18, 2026

I'll try to summon one of the organizers for this one: @johandecelle.bsky.social

Otherwise I'll try to find out!

Booping this over to #marinelife If your interests include some of the little things in the seas (microbial eukaryotes), and you are an early career researcher (defined as student or postdoc for this course), apply to join--or share with someone interested! 🦑. opbc.sciencesconf.org

Doesn't look like it this go around. Maybe in future iterations. In the US, myself and some friends have proposed radiolaria-centered single-cell workshops... Hopefully one day we get them funded. There's a bioblitz workshop coming in Nov in Okinawa-more broadly focused, but also should be fun.

I'll put your name in!

That would be so cool. I think its all booked ☹️.

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:

Just published: chemotactic sperm cells become phototactic 💡- by loading photo-activatable second messengers. This allows to "reverse-engineer" chemotactic signaling dynamics and expose cells to signals they would never see in the wild. Honoured to be part of this collaboration with the Kaupp lab.

Black people, don’t EVER let these people tell you that you are a “diversity hire” or don’t deserve the roles you have so richly prepared for & earned.

We are attending #OSM in Glasgow! This is the @biosstation.bsky.social team at the conference, from physics to biology!

I can't be the only one who is made /uncomfortable/ by the way that razor clams burrow into sand, right?

The final moments of this video by Kate Crump on the Oregon coastline are sort of the crowning glory of horror. 😬

But how does this even work?
Let's talk about bivalve mobility (if we must).
