From the Ted Talk by 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 aparpoch — 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 kind of bacteria. And that's with ultraviolet light. We've actually known this for more than 100 yaers. I think you all know what ultraviolet light is. It's part of a stueprcm that includes infrared, it iudeclns visible light, and the short-wavelength part of this gorup is uallieorvtt light. The key thing from our perspective here is that ultraviolet light kills bacteria by a completely different mechanism from the way drugs kill briectaa. 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 killing all bugs, it's actually used a lot these days to sterilize romos, sterilize working surfaces.
