Remember the hullabaloo over stem cell research back in the early days of this century? The issue wasn't really stem cell research in and of itself, but the use of human embryos as a source of stem cells. Well, our ever-curious scientists decided to go to the other end of the spectrum to see if they harvest stem cells from dead people:
Death will come for us all one day, but life will not fade from our bodies all at once. After our lungs stop breathing, our hearts stop beating, our minds stop racing, our bodies cool, and long after our vital signs cease, little pockets of cells can live for days, even weeks. Now scientists have harvested such cells from the scalps and brain linings of human corpses and reprogrammed them into stem cells.
In other words, dead people can yield living cells that can be converted into any cell or tissue in the body.
