Mystery Of The Teenage Brain
It's a question that's plagued parents for generations — why do teenagers act the way they do? Why the angst, anger and unnecessary risks? Now, scientists think they've found some answers. Science writer David Dobbs set out to explain what researchers recently discovered about the teenage brain after his son was pulled over for driving 113 miles per hour. Dobbs's story "Beautiful Brains" is the cover story in this month's National Geographic magazine. Dobbs joins host Neal Conan and brain researchers Dr. B.J. Casey and Dr. Jay Giedd for a live broadcast at the National Geographic headquarters in Washington, D.C.

The Risks And Rewards Of Exploration
Constanza Ceruti braves blistering winds and altitude sickness to study areas of the world most people have never heard of. She's an emerging explorer for National Geographic and the world's only female high altitude archeologist. While Ceruti ventures to the tops of the world, National Geographic's explorer of the year Kenny Broad dives deep beneath the surface of the world's oceans. He's an environmental anthropologist who researches fresh water pockets. Both explorers take calculated risks to help us understand more about the world. They join host Neal Conan to talk about what they do and the limits, risks and rewards of their work.

The Geographer At 'National Geographic'
National Geographic recently released a new map of Cuba. The first in more than 100 years, it includes two new states. The detailed map of a secluded country is worthy of recognition in its own right, but the real story is the cartographer behind the project. Juan Jose Valdes fled Cuba as a young boy and is not just any geographer, but The Geographer for National Geographic. Valdez joins host Neal Conan to talk about what we can learn from the new map of his homeland and what it meant to him to create it.
