Gouvernance coloniale. Peu de choses ont changé, alors qu'un gvt séparatiste québécois en attente se prépare à s'emparer et à gouverner le Nunavik, l'Eeyou Istchee Baie James et l'Abitibi Tamiscamingue, contre la volonté des Inuits et des 1ères Nations qui y vivent.

A crowd of marine embryos self-assembles into a living solid Nature Physics - Marine embryos are usually studied in isolation. But when starfish embryos are in a crowd, they self-assemble into living solids with unexpected dynamics, revealing how simple...

What happens when marine embryos are crowded instead of isolated?

They become materials.

Honored to write a @natphys.nature.com News & Views on excitable living solids discovered by Prof. Fakhri and colleagues at @mit.edu 😀

Macro photo of the head Peripatoides novaezealandicae from ventral. You can see the “teeth” very well. And if the upload quality is enough the structure of the cuticle (better than on the mCT scan). You can even see what I have called the “thingies on the thingies”.

Yet again the same worm. Regular photo this time. I just finished turning the background black. :)

The little “paws” are very cute, but the mouth is terrifying.

Evolution of monoamine reception and its role in cellular contractility.

How do #sponges coordinate their bodies despite lacking neurons and true muscles?

We show that sponges use monoamines to control water flow in their canals — reminiscent of how adrenaline regulates blood vessels.

Rethinking Economics, the movement changing how the subject is taught Born of student disquiet after the 2008 crash, the group says it is reshaping economists’ education

Students are organizing against classical economic theory because it doesn’t align with their lived reality. Good stuff. #Biodiversity & #economics & #history & #power & access to #healthcare & #democracy & #equality are inseparable.

Ediacaran fossil surface on the coastline of Newfoundland, Canada

Have they? I won't let those silly turkeys sully my appreciation of ancient wisdom. You've done a lovely study. Your methods are beyond me, but the question is an oldy & a goody.

The timing and nature of marine ecosystem recovery following the Permian-Triassic mass extinction - npj Biodiversity npj Biodiversity - The timing and nature of marine ecosystem recovery following the Permian-Triassic mass extinction

Exciting news! Our invited perspectives in npj Biodiversity looks at how marine life bounced back after the worst mass extinction ever, the Permian‑Triassic Mass Extinction (PTME) ~252M years ago. Big questions: fast or slow? recovery or restructure?

We encourage excellent early career scientists (i.e., PhD candidate gaining doctoral degree before 9 September or scientist with max. 8 y full-time equivalent experience in research by 9 September), who are interested in applying for a MSCA Postdoctoral Fellowship in Ecology at the University of Tromsø (UiT) to send in their application (max. 3-page CV & 2-page project plan). Deadline for application of intramural selection of candidates is 16 February. Chosen candidates will be supported by UiT to write an application for MSCA postdoctoral fellowship (deadline 9 September 2026). If granted (21-39% success rate for intramurally supported applications since 2018), the project shall start 1 May 2027. For more information about the application process and to apply see https://euraxess.ec.europa.eu/jobs/403197.

Regarding scientific background of project, we are interested in estimating the impact of ocean warming on benthic communities. For this purpose, unheated settlement panels (= control) and panels heated 1, 2, and 3 °C above ambient seawater temperature have been put out at 10 m depth in a fjord near the island of Tromsø in September 2024 (more information at Heated settlement plates (HSPl) in global experimentation: Experiences, research questions, future applications and collaborations). All panels had been photographed after 1 y of field incubation in September 2025 and more sampling is planned in 2026, to take samples for species identification ("ground truthing" of photographed individuals in collaboration with David Barnes at BAS, UK) and gene expression studies. Furthermore, there are tank facilities at UiT to measure physiological responses of organisms from unheated and heated panels. We are interested to hear about your ideas and read your research plan within the scope of the heated panels experiment.

Cool postdoc opportunity in Norway to evaluate global-change impacts on marine communities. Application info at euraxess.ec.europa.eu/jobs/403197 🌊🦑

Minneapolis community defies ICE to warn immigrants of approaching agents If there’s been a soundtrack to life in Minneapolis in recent weeks, it’s the shrieking whistles and honking horns of thousands of people following immigration agents across the city.
