It sounds too good to be true: a substance called Pixie Dust that is capable of re-growing human limbs. But it’s real, and it’s already being used by surgeons to save wounded soldiers in Afghanistan. The powder, which is actually made up of a collagen-filled substance from pig bladder called extracellular matrix, has previously been used to regrow human bladders, and now it’s set to revolutionize the treatment of amputated limbs.

Scientists aren’t sure why pig bladder has such a unique quality, but they think that the Pixie Dust attracts cells in the body and signals for them to generate new tissue. The miraculous material has passed beyond the research stages — surgeons are treating soldiers in Houston, Texas, who might otherwise have faced amputation. And while the powder isn’t widely used quite yet, the Pentagon is investing millions in research so that Pixie Dust might one day be the treatment of choice for injured soldiers everywhere.
