It is absolutely wild that the guy who won’t stop yelling about law and order is now personally stepping in to keep January 6 documents hidden from the police officers who were attacked that day. He knows exactly what’s in those files and he is terrified the country will see it.

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!
