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.

If one of the appliances in your home, say your cooker or fridge, ran using ten times the power of a normal one, you‘d replace it as fast as possible and never go near that manufacturer again, because you’d think they were catastrophically bad at making stuff.

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 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!

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. 🧵
