All press releases are exaggerated, but this: “A type of ultraviolet light called Far-UVC could dramatically change how we combat the transmission of airborne pathogens in indoor environments, scientists report in a new study…” does seem to be backed up by the actual paper. Short version is, they think they’ve got a method for using UV light to fry pathogens without the radiation being at levels where it’s also burning your skin, wrecking your eyes, or giving you skin cancer. Which, if it works, would be enormously helpful in medical facilities.
It’d also be killer (heh) against vampires, but that’s another issue entirely.
