Kgnu - How On Earth

This week we'll feature CU Medical School Immunologist John Cohen, who has just received the American Association for the Advancement of Science top award for promoting public understanding of Science.  In addition to teaching at the Medical School, Cohen is the founder of Mini Med and the lead "disorganizer" of the Denver Cafe Sci.  We'll also talk with Emory University researcher Zixu Mao about a new link between Parkinson's disease and the health of the mitochondria within a cell, and we'll hear from BBC Science in Action about some top choices in Europe for new Astronomy pursuits.
