We’ve discovered how the superbug E. faecalis prevents chronic wounds from healing.

It’s not a toxin. It’s metabolism.

The bacteria use extracellular electron transport (EET) to electrochemically generate ROS, effectively "freezing" skin cells in place.

Enterococcus faecalis redox metabolism activates the unfolded protein response to impair wound healing
E. faecalis EET generates ROS, which induces the UPR in keratinocytes, inhibiting in vitro migration.

Light-activated metal complexes have been shown to disable antibiotic resistance enzymes in E. coli, significantly enhancing the effectiveness of existing antibiotics without harming human cells. doi.org/hbcxrb
How phototherapy could reverse antibiotic resistance
Lars Stevens-Cullinane works in a dark room. But he's not processing negatives and printing photographs on light-sensitive paper; he's testing whether brief flashes of light can make drug-resistant bacteria sensitive to antibiotics.

Important piece from Sarah Stanley at Berkeley on new NIH definitions that can be construed to arbitrarily halt research that is both safe and important to public health and future cures www.statnews.com/2025/10/06/g... via @statnews.com
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.
