En révolutionnant la façon dont nous voyons les animaux et par extension nous-mêmes, Jane Goodall a changé le monde.

Pionnière de l’éthologie et défenseuse inlassable de la faune sauvage, elle laisse un héritage inestimable.

Et elle inspirera des générations de petites filles.

We uncover that the caudal splanchnic mesoderm (in green) acts as a midline anchor of the heart tube. In Vangl2 and Shroom3 mutants, its bilateral symmetry is disrupted, leading to a rotation of the heart tube and ventricle malposition.

New publication :
Despite being a core member of the PCP pathway, Vangl2 can play roles unrelated to planar polarity. This is the case during mouse heart morphogenesis.

Do you want to listen to me ramble about Pasteur's Image Analysis Hub (research.pasteur.fr/en/team/imag...)?
Let's meet online next Monday. I will present how we work, and what we have learned in delivering bioimage analysis support in the past 7 years.

Despite their high rigidity, microtubules (MTs) dynamically bend and buckle in cells. MT-self repair is inherent to their metastable nature, but it remains unclear whether just inherent repair mechanisms are sufficient to maintain MT integrity🧵 (1/9)

Il y a moins de 3 ans, personne n'utilisait ChatGPT. Aujourd'hui, c'est semble-t-il devenu indispensable pour des millions de Français. Mais à quel prix ?

Consommation d'électricité, consommation d'eau, extraction de matières premières... l'intelligence artificielle est un gouffre énergétique.

As hinted earlier, the biggest change in #PoCA to date: support for 2D/3D image data! 🧩🖼️ In fine, point clouds will be no longer the only game in town—PoCA is evolving into a more general spatial analysis platform. This (maybe too long) movie shows what's coming!

@cnrsecologie.bsky.social regrette profondément l'adoption de cette loi à la vision court-termiste & ses conséquences graves sur l’environnement, qui méprise santé & bien-être de la population & le rôle des espèces sauvages dans la prod. agricole. La communauté scientifique n'a pas été entendue.

Le gouvernement Macron a voté, avec la droite et l’extrême-droite, POUR la loi Duplomb à l’Assemblée nationale.
