How does the early life microbiota protect the infant against excessive adiposity? Our new preprint describes a mechanism by which specific members of the early life small intestine microbiota regulate intestinal epithelium-immune interactions to prevent adiposity. www.biorxiv.org/content/10.6...

Small intestine microbiota development prevents early-life adiposity via IL-22-mediated intestinal PPARα suppression

Perturbation to the early-life microbiota has long-term detrimental effects on health and development, leading to increased risk for metabolic dysfunction and childhood obesity. Despite the central ro...

Friday we lost a brilliant mind, colleague, and friend to her battle with pancreatic cancer. Those who knew her will remember Helene Andrews-Polymenis for her warmth, generosity and leadership. She will be missed by many. RIP

Channel your science anxiety into action. Comment on or before tomorrow! Keep scientists in roles at NIH and NSF and keep politicians out of them. Tell your non-science friends — universally hated idea to put politicians in these roles! 🧪

Deadline to comment is Friday. Turn that Friday science dread into something something comment! Also, it needs a hashtag, #FriSciDread

My student's diversity F31 has been pulled from study section even though it's the SAME APPLICATION as regular F31s, normally reviewed together in the same panel. Throwing out all the applications from URMs while the ones from white/privileged students get to be reviewed is blatant discrimination.

Jeff Weiner@jlweiner.bsky.social · last yr.

The CSR comm I'm on just pulled all Diversity F grants from the current review cycle. These apps are reviewed alongside (and by the same criteria) as all other F grants. So, instead of helping these trainees, they will actually be punished by having their grant reviews delayed at least 1 cycle !?!?

Also sharing the “Meet the Authors” highlight published with the review. Very proud of my amazing trainees Katerina Jones and Camila Brito for sharing a bit of their stories as the next generation of talented Latin Women in Science! www.sciencedirect.com/science/arti...
