I think it is interesting that the cure for polio was found 64 years ago, a very specific disease, where the cure involved stimulating the immune system. Now today they are talking about stimulating the immune system in a more general way to fight cancer. It has taken science way too long to appreciate the immune system we each have within us. Have no idea what Theranos claims but since they are talking about a drop of blood or less I will guess it involves nano technology, which I hear is very hot in upstate New York.
