From time to time, Talk of the Nation and National Geographic team up and broadcast live in front of an audience at Geographic's D.C. headquarters.

Last January, Neal Conan spoke with National Geographic explorers Robert Ballard — best known for discovering the Titanic — and Jill Pruetz about what's left in the world to discover.

We're taking the show back to National Geographic on September 20th, and will pick up on that theme: The limits and risks of exploration.

From the deepest caves in the ocean to the highest snow-capped peaks, are there limits to how far an explorer will go? How does one balance safety and the pursuit of the unknown? What is worth the risk? To answer these questions, we've invited two National Geographic explorers for whom risk-taking is just a part of the job. Joining us for this conversation will be deep-sea cave diver Kenny Broad and high-altitude archaeologist Constanza Ceruti.

We'll also spend an hour talking about National Geographic magazine's October cover story on the teenage brain:

To many adults, teenagers are a mystery. It's difficult to understand why they act the way they do, why they take the risks they do. Scientists have tried for centuries to figure it out. Now some scientists think they have an explanation — evolution. Studies suggest that teenagers are highly adaptive — wired almost perfectly for the job of moving into adulthood from the safety of home to the complicated world they will inherit. David Dobbs, author of the cover story on the teenage brain in the October issue of National Geographic, will talk with scientists in the field — and listeners around the world — to discuss how the adolescent brain may be wired for risk.

In a final segment, Neal will also speak with Juan Jose Valdes, creator of a new map of Cuba, National Geographic's most comprehensive one since 1906.

If you would like to join us in the studio audience, please send an email to with your name and the number of tickets you'd like to reserve. Please put "tickets" in the subject line. You can attend one or both hours, so please indicate your choice.

You must be seated at Grosvenor Auditorium by 1:45 pm on Tuesday at the National Geographic Society headquarters: 1600 M Street N.W., Washington, D.C.
