📅 On October 10–11, members of @inrae-umr-bf2i.bsky.social & MAP will guide you through the alleys of La Doua Campus to talk all about symbiosis!
✨ Book your slot here 👉 www.fetedelascience.fr/la-symbiose-...
🎉 Join us for a fun time at Fête de la Science!

La symbiose dans tous ses états

Lors de cette balade conçue par Street Science, vous irez à la découverte de la symbiose, cette relation durable entre 2 organismes d’espèces différentes, parfois bénéfiques pour les deux, mais pas to...

Yesterday @ritarebollo.bsky.social brilliantly obtained her Habilitation à Diriger des Recherches in front of a jury composed of L. Teysset, C. Vitte, F. Hommais, N. Nègre, Z. Haichar & N. Kremer. A summary of 20 years of research in 3 labs & 2 countries with a common theme: interactions! 👏

Hi! We are looking for a PhD to work on the cross talk between transposable elements, insects and intracellular bacteria on the bioinformatics side. The PhD would be supervised by @mariefablet.bsky.social and myself along with @nicolasparisot.bsky.social Deadline December 2025! Please share! #tesky

📣 #OurLastPaper is out! This study explores the functional specialization of the symbiont-bearing organ in the rice weevil.
Using microdissection coupled with dual RNA-seq, we revealed different cell types, each with distinct host-symbiont molecular dialogues. #SymbioSky
