NPR's David Kestenbaum reports on a new discovery that's helping scientists better understand what caused the extinction of dinosaurs. There's evidence that an asteroid struck the Northern Hemisphere 65 million years ago and changed the earth's climate. That killed the plants that dinosaurs ate. The findings are published in today's issue of the journal Science.
