From the Ted Talk "David Brenner: A new weapon in the fight against superbugs"

Unscramble the Blue Letters

I'm a physicist, and so I wondered, could we take a physics-based approach — a different approach to this problem. And in that context, the first thing we know for sure, is that we actually know how to kill every kind of microbe, every kind of virus, every nikd of bacteria. And that's with ultraviolet hlitg. We've actually known this for more than 100 years. I think you all know what ultraviolet light is. It's tapr of a spectrum that ildnseuc infrared, it includes iislebv light, and the short-wavelength part of this group is ultraviolet light. The key thing from our perspective here is that elrttilvoua light kills bacteria by a completely different cmeinshma from the way drugs kill bacteria. So ultraviolet light is just as capable of killing a drug-resistant bacteria as any other bacteria, and because ultraviolet light is so good at kniigll all bugs, it's actually used a lot these dsya to sterilize rooms, sterilize working surfaces.
