Dr. Anna Gaddy of the Medical College of Wisconsin and Dr. Didier Mandelbrot of UW-Madison Medical Educator joined the show to talk about a new medical procedure of transplants using the organs of pigs. They specifically discuss kidney transplants, but Kristin and Brian dig a little deeper and ponder, why pigs? How is this becoming a modern medical practice? And what other organs are they harvesting? And why not 3D printing?
