The sample return capsule from NASA’s OSIRIS-REx mission is seen shortly after touching down in the desert at the Department of Defense's Utah Test and Training Range on September 24, 2023. The sample was collected from the asteroid Bennu in October 2020 by NASA’s OSIRIS-REx spacecraft. CREDIT: NASA/Keegan Barber

Chemical analysis of carbon and nitrogen isotopes in glycine from the asteroid Bennu suggests that the amino acid in the asteroid formed differently than the glycine found in the Murchison meteorite. In PNAS: https://ow.ly/hq3T50YetQ2

Pleased to share the final version of this behemoth of a paper, now finally published. I guess I can retire now?

More functional data, many thousands of words removed, and a few other updates from last year's preprint.

We are thrilled to announce the recipients of the 2026 Postdoctoral Award of the @biophysicalsoc.bsky.social IDP Subgroup: Srivarsha Rajshekar (Berkeley, USA) and Tongyin Zheng (Brown University, USA). Listen to their talks at the IDP Symposium!

C'est comme ça chez nous depuis longtemps... En tant que personnel hébergé une technique qui marche c'est d'acheter l'ordinateur avec la tutelle A et de livrer à la tutelle B. Comme ça la DSI de A ne voit jamais l'ordi et la DSI de B ne sait pas qu'il existe.

I wrote this song on Saturday, recorded it yesterday and released it to you today in response to the state terror being visited on the city of Minneapolis. It’s dedicated to the people of Minneapolis, our innocent immigrant neighbors and in memory of Alex Pretti and Renee Good.

I think we're currently in the "radium skin cream" phase with AI.

When we discovered radioactivity, people tried to cram into everything, and it didn't end well.

AI is a discovery at least as important as radioactivity, and at least as dangerous.

“The costs of competing for grants can exceed what the grants are worth”, wasting public money.

Two models minimise the overhead of grant writing and evaluation:
– lottery

We resolved the molecular architecture of a condensate—inside cells. 🤯 By combining in situ cryoET with multiscale simulations, we show how a single point mutation modifies molecular interactions, shifts the condensate’s material properties, and alters its biological function. Preprint 👇

Brève de sciences : comment créer de nouveaux matériaux ?

Aujourd’hui les #PFAS sont omniprésents. Mais est-il possible de remplacer ces substances par des alternatives sûres pour la santé humaine et l’environnement ? C’est à ces questions que cherche à répondre Frédéric Leroux, chimiste organicien au CNRS.
