The right-wing think tank which wrote the entire platform for the current president of the US is defending neo-Nazis, and meanwhile a substantial portion of American rabbis think the Muslim candidate for NYC mayor who has denounced antisemitism is the biggest threat to me as an American Jew.

The NIH ordered me to stop my ‘dangerous’ gain-of-function research. It isn’t dangerous at all
Safe gain-of-function research is necessary to identify new treatments for diseases like for tuberculosis — but the NIH has imposed unfounded stops.

Our latest efforts to understand Enterococcal wound infection. In long-term collaboration with @gthibault.bsky.social, we discovered how E. faecalis makes extracellular ROS - via EET!⚡️Which in turn dysregulates host UPR to delay wound healing. Led by @aarontan.bsky.social - his videos below are 🤩!
📢 Our new preprint is out! We show how the common gut bacterium 𝘌. 𝘧𝘢𝘦𝘤𝘢𝘭𝘪𝘴 stops wound healing. It uses a metabolic pathway, extracellular electron transport (EET), to stress host cells, halting their migration. Watch WT bacteria (orange) stop the cells while the mutant (blue) doesn't!

This is very bad. “One weird budget trick” that will cut the number of grants this year in half! 🧪

New, from an anonymous NIH insider: Trump is being pushed to spend more NIH money. The White House is ordering NIH to do multi-year budgets for awards. This budget trick means fewer awards, fewer labs funded, and lower paylines for researchers. 🧵
