How a Key Enzyme Repairs Sun-Damaged DNA 97

BraveHeart writes "Researchers have long known that mammals, including humans, lack a key enzyme — one possessed by most of the animal kingdom and even plants — that reverses severe sun damage. For the first time, researchers have witnessed how this enzyme works at the atomic level to repair sun-damaged DNA. 'Normal sunscreen lotions convert UV light to heat, or reflect it away from our skin. A sunscreen containing photolyase could potentially heal some of the damage from UV rays that get through.'"

Yeah, but the intention definitely matters. The adult photographer is clearly trying to get photographs of strange children, whereas Google is trying to build a useful service. I'd say Google's use is a lot less creepy than the strange guy.

Here's a car analogy: If you cut me off because you're rushing your pregnant wife to the hospital through dense traffic, I don't mind. But if you cut me off because you're talking on your cell phone and not paying attention, we have a problem.
