Advancements in medicine never cease to amaze me, but this story (make sure to watch the video) in particular, about regenerating body limbs, pretty much blew my mind.
This guy, Lee Spievack, chopped the tip of his finger off. His brother (a medical research scientist) sent him a powdery substance to sprinkle on the wound.
Lee sprinkled, like so…
…waited 4 weeks and his fingertip grew back, fingernail and all…
before
after
Looks like magic to me.
