Ever wonder what proportion of high profile social media research is tied to the tech industry?

Enterococcus fans: Check out our latest on E. faecalis EET, advancing our understanding of both the fundamental physiology of this bug and new mechanisms of its virulence. This is the product of a thrilling collaboration with friends in Singapore @gthibault.bsky.social led by @aarontan.bsky.social.
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.
