Specifically, Chivian looks at how studying polar bears in their native habitat could help scientists address such human health issues as osteoporosis, renal disease, and obesity related diabetes. He describes how cones snails contribute significantly to the development of medication for chronic pain in patients who no longer respond to opiates.
