On Friday’s show

During MPR’s pledge week, we’re playing some of the best Daily Circuit conversations you might have missed:

9:00 Lonnie Dupre and Ann Bancroft discuss their travels to the world’s polar regions.

Bancroft says that there are still corners of the Earth to explore. “Much of Antarctica that we trudge through is unmapped,” she says.

Dupre says that geographic exploration and adventure aren’t his only goal; he now functions an at-large lab assistant. “We hit those extreme areas that make it difficult for scientists to get to, he says. “By being able to collect samples, whether snow samples or rock samples, we can collect those and bring those back from our trips.”

10:00 Adam Johnson, author of a novel set in North Korea “The Orphan Master’s Son.”

“My main goal was to try to humanize what I saw as ‘regular people,'” says Johnson. “In North Korea, you’re not in charge of your own life. People come into your schools when you are a kid. They have tests that measure your aptitude for certain things and you’re going to be a fisherman. Or a ballerina.”

11:00 Can prisoners be redeemed? We hear from Nancy Mullane. Her book is “Life After Murder,” the story of five convicted murderers and their struggle for redemption. The question she pursued in her reporting: “Who are people who commit murder after they have been in prison for 20 or 30 years?” Tune in for the answers.
