We talk with a scientist en route to the South Pole who is hoping to collect data about Earth's climate history. Also, a paleontologist talks about a 70-million-year-old baby plesiosaur out of Antarctica's permafrost. And we hear about a new telescope being built more than a mile below the surface of the ice.
