It's a wrap for the 2026 Quebec #Indigenous Science Fair in La Tuque. The theme was 'Science in Action with 1st Peoples' & included 41 teams & 9 nations, illustrating the growing interest of 1st Nations & Inuit youth in science & technology. Thanks to our hosts, le Conseil de la Nation #Atikamekw!

Canada is a proud, bilingual nation. Our history and culture is shaped by the French language and the millions of Canadians who speak it every day.

La Francophonie is a pillar of our national identity — one to be protected and celebrated across Canada.

I should mention that we did find a juvenile, arms wrapped around the disk to form a ball.

The rods are hard and fractious. The brittle stars were fixed in EtOH, so the preservation is not great, but the rods appear to be inside the bursa. I could see them through a bursal slit.

Help! We're removing the aboral disk of the brittle star Amphipholis squamata in search of juveniles - they're brooders - and we're finding these hollow ossicle-like rods, arranged in sequence. What the heck are they? #ophiroid #echinoderm #calcite

Looking for a #PhD project?

The #DEEVA team (biom.obs-banyuls.fr/presentation...) proposes a PhD research project on the evolutionary modifications in the formation of the palps, the sensory and adhesive organ located at the anterior end of the #ascidian larvae.

Read it. It’s a repackaging of old ideas. Nothing new to move the field forward.

Earth’s first major extinction was worse than we thought Fossil finds suggest nearly 80% of life on Earth died some 550 million years ago

Extraordinary new fossils from Newfoundland reveal an ancient mass extinction worse than the asteroid-driven calamity that killed the dinosaurs.

Goodbye friend. I'll always remember you for your easy, beautiful brilliance. You've been an inspiration. Thinking of your family and our shared friends everywhere today.

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.

What happens when marine embryos are crowded instead of isolated?

They become materials.

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.
