This interesting article is about the guy that won a Nobel prize for his work in taking adult cells “back in time” to make stem cells. They actually created a beating human heart from regular cells. It had previously been thought that that could only be done with true stem cells which must be collected from embryos. It will bust wide open the medical field but may not be feasible for a few decades. Bummer for us older folks.
