Zinc Sparks Control Reproduction: Thomas V. O'Halloran, PhD at TEDxNorthwesternU

Romantics often look for emotional 'sparks' when they meet a potential mate. An interdisciplinary research team shows how the egg and sperm experience similar fireworks at the molecular level: the egg scavenges massive quantities of zinc in the hours before the arrival of sperm charming, and then undergoes waves of zinc sparks upon fertilization. Intriguingly, biology is using zinc (an inorganic substance that it can neither create nor destroy) as a master switch in development.Dr. Thomas V. O'Halloran leads a highly interdisciplinary research group which works across the areas of chemical synthesis, analytical chemistry, biochemistry, molecular biology, endocrinology, oncology and cell biology. In his role of the Director of the Chemistry of Life Processes Institute at Northwestern University, Professor O'Halloran administers and leads teams from across the fields of science, engineering and medicine. He also serves as the Associate Director for the Basic Sciences Research Division of the Robert H. Lurie Comprehensive Cancer Center.About TEDx:In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience.
