Scientists who have developed an innovative cancer treatment have now moved to human clinical trials. By using a specific sort of white blood cell, called a granulocyte, taken from healthy young mice and transferring them to mice with cancer, researchers were apparently able to affect a 100% cure rate. Whether or not the technique will work with humans is another matter, but previous lab-based tests seem to be promising. A cure in our time? Probably not, but it definitely sounds like a new weapon is about to be brought to bear on the problem.
