Hmmm... interesting. It doesn't sound like there was any bone or muscle growth just skin regrowth. If that is the case then I can completely believe it because it happened to me. When I was attending Art school, yes I admit it, I sliced off the tip of my finger with an Exacto blade. Granted, they just superglued the tip back on and let my finger regrow back to the tip but it was very similiar.

Yeah, that's part of why I can believe this, it appears to just be flesh. Still, getting full feeling back that fast is impressive. Interesting that the nail on that finger seems to permanently grow faster. Hope this "magic dust" gets more research.

It sould be really cool if it does work on skin and they can get it to work on bone and muscle too. Star Trek, here we come.

That's pretty cool. Technically there's no reason we shouldn't be able to re-grow body parts, at least on a simple level. It already exists in nature, all we have to do is figure out how to make our bodies do it too! :D

Given what little I know about physiology (biology BA, but still...), this doesn't raise any big red flags. I like it. While I was in my neurophysiology lab course in collidge, my small class got to hang out with a researcher who'd managed to show that failures of nerve regrowth weren't anything endemic to nerve cells themselves, but rather a function of what goes on in the scarring area. He'd been able to facilitate nerve regrowth by suppressing something or other. I don't remember what methods he used, but just knowing that the possibility exists and that it didn't require anything really wacky leads me to find this bit of news believable.
