Since graduating from D.C. Everest Senior High School in 1957, John Wayne Kennedy has helped discover the Lost Pyramids of Rock Lake in Lake Mills, worked as an investigator for the U.S. Department of Agriculture, published a novel and consulted for companies dealing with pesticides. For the past three years, he has found another focus: sending plant and human stem cells into space to see how they reproduce, and in the process creating hardier versions of the plants and perhaps even human organs. The project stemmed from a question heâ??d asked as a biology student at the University of Wisconsin-Madison in 1960: How would plant cells reproduce in zero gravity?
