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:

The emergence of a chemical system capable of self-replication and evolution is a critical event in the origin of life.

This paper describes a ribozyme, a catalytic RNA molecule, able to do just that..

Fascinating stuff…

Renee Good's partner addresses Minneapolis immigration crackdown one month after killing Becca Good has seldom spoken out since Renee Good was shot and killed by an ICE agent in Minneapolis on Jan. 7.

“Renee was not the first person killed, and she was not the last,” Becca Good said. “You know my wife’s name and you know Alex’s name, but there are many others in this city being harmed that you don’t know — their families are hurting just like mine, even if they don’t look like mine.”

As usual the reviewers from the #circadian research field provide constructive and useful reviews that improve better readership […]

Vamos sim!! Adoraria ouvir a opinião de alguém versado em oceanografia e ecologia marinha, é algo que eu gostaria bastante de explorar no futuro, mas eu entendo quase nada a respeito rs

New preprint from our lab: even when the SCN (the central circadian pacemaker) looks broadly similar in diurnal and nocturnal animals, its underlying dynamics can differ substantially.

Suzana, eu acabei de perceber: você é brasileira?? Fico sempre animada quando encontro outros brasileiros em áreas relacionadas com a que eu trabalho!

We would like to express our sincere appreciation to Terry Page for his wisdom and advice over the years. Several of us (M.C.T., J.R.J., M.L.J.) had the honor of having Terry serve on or chair our dissertation committees during our graduate training at Vanderbilt University, and in this role Terry provided innumerable contributions to our work. Beyond his official capacity as a committee member, Terry was also an integral part of our training as chronobiologists, assisting us with challenging conceptual topics, discussing classic and modern circadian literature, and always being willing to have a chat about chronobiology or science in general. We are deeply grateful for his direct contributions to our careers and for the examples he has set for us as a scientist.

Pictured, Terry and me on the day of my PhD defense.

this paper was for Terry Page's festschrift (ie a collection of articles put together to honor an academic in their lifetime)

Terry shaped so much of my scientific career, it's really not an understatement to say I wouldn't be the scientist I am without him. Very happy to get a chance to honor him!

out now, the one mammalian paper I somehow found myself being a part of! With Michael Tackenberg, @jonesjeffr.bsky.social and Vinnie Cassone.

In it, we discuss temporal niches, coupling and the organization of circadian networks.

If current admin knew that vaccination might also prevent dementia, would they still be against it?

As a neuroimmunologist my heart breaks twice at their anti-vax policies: once for the devastating effect it will have on infectious disease, and again for losing a potential tool against dementia.

Could different bacterial species work akin to the arms of a classic TTFL, and could rhythmicity be a function that gets selected not only at the species, but also at the community level?

+question: why, despite our efforts, has it been so hard to find circadian rhythms outside of cyanobacteria? We propose a Big Speculation as an answer: perhaps (circadian) rhythms aren't exclusive to the species level, but could be an *emergent* property at the community level. +

I learned of this amazing poem by means to Sanah Ahsan's similarly amazing essay
poetrysociety.org.uk/poets-readin...

"(...) To endure
the endless walk through the self, knowing through a bond
that has no basis (for ourselves are all we know)
is altruism: not giving, but coming to know
someone is there through the wavy vision
of the self's heat, love become a decision"
