Well, this is amazing: a new medical technique to treat burns involves spraying the affected area with the victims own stem cells, which results in major burns healing in a matter of days.

In the below video (warning: some nasty burn images in there), you can see the results of a man who received 2nd degree burns in a gasoline fire and was healed over the course of a weekend. A weekend! It seems like something out of a movie, but this is very real.
