Chad Cohen comes to NOVA scienceNOW after nearly four years as a science correspondent and producer for the National Geographic Channel. He has searched for lost cities under the slums of Cairo, juggled weightlessness and nausea in NASA's "vomit comet," and, most recently, was charged by an Asian one-horned rhino while he was investigating India's wild elephants.
