Love this quote from Mauricio Pochettino, USA National Team coach: “Let’s be realistic, and do the impossible.”

Such a treat to be sitting in the room where @denisduboule.bsky.social is giving a talk @fsscr.bsky.social meeting in Lyon! Exciting and insightful science ahead 🤯🤘

The second day of the #FSSCR2025 meeting is starting by an exciting presentation on adult neurogenesis in vertebrates by @zaycha.bsky.social.

The Coming Out of a Transgender Scientist "I know that I am making the right decision because whenever I think about changing my gender role, I am flooded with feelings of relief."

We're disappointed to see Ben Barres's powerful book "The Autobiography of a Transgender Scientist" among the ~400 titles removed from the Naval Academy Library. Needless to say, we're proud to have published his book and will keep it — and his memory — alive.

So sorry am missing this! I would love to meet you in person one day! Enjoy Saint Rémy :-)

STORIES: learning cell fate landscapes from spatial transcriptomics using optimal transport - Nature Methods By learning a differentiation potential using an optimal transport-based approach, STORIES models and infers cell fate trajectories using spatiotemporal omics data.

Happy to share STORIES out now on Nature Methods

STORIES learns cell fate landscapes from spatial tramscripromics data profiled at several time points, thus allowing prediction of future cell states.

Led by Geert-Jan Huizing and Jules Samaran

Social interaction in mice suppresses breast cancer progression via a corticoamygdala neural circuit Wen et al. reveal that social interaction reduces breast cancer progression by activating ACCGlu→BLAGlu circuits, inhibiting intratumoral sympathetic activity. This neural mechanism enhances antitumor...

Cool cool cool!

I am thrilled to share our latest work: we identified a population of central amygdala neurons that promote the earliest and perhaps most important social behavior: pup suckling!... We also developed new tools for pup neuroscience
