Oh wow.. this is just one of the most awesomest sciency things I’ve ever heard.
So, you’ve heard of stem cells? Those cells that can be thought of as building blocks, and that potentially will allow us to grow whole new organs or limbs for use in transplants? They are, as I like to think, damn cool biology stuff.
Well, stem cells can get bad press, because the easiest and most heard of method of making them is to create an embryo.. but hold on a gosh-darned-tooting second I hear you cry.. what about all those awkward ethical questions?!?!
Do not fret! I say, because stem cells can be made from skin cells! Also, researchers at Technion Israel Institute of Technology have managed to turn those stem cells into beating heart muscle! Awesome!
