Microbiota shape the colon epithelium controlling inter-crypt absorptive goblet cells via butyrate–GP R109A signalling
The colonic epithelium is a key interface between the gut microbiota and the host. How microbiota-derived signals influence epithelial cell identity and function remains incompletely understood. He...

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
🚨 A new rule would let career scientists like NSF/NIH program officers be replaced by political appointees
Already 14,000+ public comments, deadline is Friday
📣 Comments can be short. Courts consider them—and scientists with NSF/NIH experience are especially impactful
Speak up! shorturl.at/WKuBj

As more information emerges about the firing of probationary employees from the NIH, it’s becoming clear how these actions are cruel and stupidly incompetent.

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.
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!
