Newts have the amazing distinction of being able to regenerate almost any body part. University of Dayton Biology Professor Panagiotis Tsonis does not know exactly why they do it or how they do it, only that they can do it. He wonders if the human body, where regeneration genes have apparently been silenced, can be turned back on. Tsonis thinks studying the newt's eye lens is the key and is involved in a research project now to learn more. Ann Thompson reports in "Focus on Technology."
