These are embryos of a jellyfish, made up of cells that are about a fiftieth of a millimetre in size. Their outlines are visible thanks to fluorescent markers identified by Sarah Asaf and @clytia-vlfr.bsky.social see doi.org/10.1101/2024... 🧵

What are these? You are looking at embryos of a sea squirt. Each of the 'soap bubbles' is a living cell, about a fourtieth of a millimetre in size. The outlines of the cells are visible thanks to fluorescent markers identified by Hitoyoshi Yasuo @hitoyas.bsky.social see doi.org/10.1101/2024... 🧵

We hire! The CytoMorpho Lab is looking for an engineer with a background in cell and molecular biology to join our team in Paris. This is a 18-month contract position, but we're open to exploring long-term opportunities. More details here: cytomorpholab.com/index.php/jo...

@biodev-vlfr.bsky.social Ready for the "Fête de la science" 🐙🪼🔬🦠. Village des sciences Villeneuve-Loubet @imev-mer.fr @sorbonne-universite.fr @cnrsbiologie.bsky.social

La quasi-totalité des méduses mènent une double vie : fixées dans les fonds marins ou libres dans l’eau. Mais certaines ont échappé à ce cycle et passent toute leur vie à dériver. Selon une nouvelle étude, ces espèces dites holoplanctoniques ont colonisé l'Océan. Dériver pour mieux régner !

This is a swimming sea slug. This type of slug, called a dendronotus nudibranch, can grow nearly a foot long in the Vancouver area where this was filmed. While they're often found on the seafloor, they can also fold their bodies to drift with ocean currents 📽️Marcelo Johan Ogata bit.ly/3a8lVQP

A 8500 années-lumière de nous, dans un des bras de notre Galaxie, la Voie Lactée, on peut trouver un endroit hallucinant, peut être le plus beau connu de l'Univers. Pas facile d'y partir en week-end, mais ça vous dit d'aller y faire un tour? Je viens d'en faire cette image Thread👇 Bon voyage!

Encore une image hallucinante du JWST, qui nous révèle la mort de deux étoiles !

#Communiqué 🗞️ 14 articles scientifiques révèlent l'ampleur de la pollution par les 𝐦𝐢𝐜𝐫𝐨𝐩𝐥𝐚𝐬𝐭𝐢𝐪𝐮𝐞𝐬 en Europe 🇪🇺. La Mission Tara Microplastiques (2019) a étudié l'origine et les flux de la pollution plastique dans 9 fleuves européens. 👉 www.cnrs.fr/fr/presse/mi...

Cette image vous présente le reste de l'explosion d'une étoile en supernova, dont la lumière nous est parvenue il y a ~1000 ans. C'est une combinaison d'images en rayons X, infrarouge et en radio. Au coeur de W49B se trouve peut être le trou noir le plus récent de la galaxie.

Prévisions météo, maladies émergentes, suivi des étoiles… Oui, le coup de rabot sur la science aux États-Unis nous concerne et "l’impact est énorme !" Secteur par secteur, voici pourquoi (avec des exemples concrets) ⤵️ @le_Parisien www.leparisien.fr/sc...

Notre galaxie voisine, Andromède, se trouve à 2,5 millions d'années-lumière. On peut la distinguer à l’œil nu dans un ciel dénué de pollution lumineuse. Dans le ciel, elle apparaît plus grand que la pleine lune, mais il faut un appareil photo pour la voir comme ça! ©D. Kananovich

If you like snowflakes, check our new preprint about axial patterning in brittle stars ⭐ We looked at the expression of anteroposterior patterning genes in Amphipholis squamata juveniles, and compared it with existing data from other classes www.biorxiv.org/content/10.1... @lowelab.bsky.social

In this fundamental study, scientists uncover a key mechanism in jellyfish embryos that provides new insights into how the body plan of these animals develops along a central axis from their ‘head’ to ‘tail’. https://buff.ly/3QgH4wH
