17-41 Segment 2: Bats: Their value and their endangerment


This Halloween, you might see some trick or treaters on your doorstep wearing either all pink or all black costumes. If so, they are probably dressed as characters from a popular new book series called The School for Good and Evil. We talk with author Soman Chainani about how he was inspired to correct what he felt were all the “wrong lessons” in the fairy tales he grew up reading.

In Chainani’s best seller, every four years two children are abducted from the town and sent off to an institution where ordinary boys and girls are trained either to be fairy tale heroes at the School for Good, or villains at the School for Evil. The books begin as two friends, Sophie and Agatha get whisked off to seemingly the wrong school. Good girl Sophie can’t understand why she’s been assigned to the School for Evil, and  Agatha, with her shabby clothes, horrible pet cat, and dislike of nearly everyone, is surprised to be taken to the School for Good. Clearly, there’s been a mistake. The story then continues as each of them must discover exactly why they ended up where they did, with the lesson being that some things are more complex than they might seem at first look..

Each book in the series plays with a simplistic dichotomy that Chainani wants to examine, whether it’s good vs. evil, boys vs. girls, or  truth vs. lies. Chainani’s goal is to encourage readers to challenge the stereotypes and preconceptions found in many of the fairy tales we grew up with.

16-04 Segment 2: Lab-Grown Diamonds and Gems: Are they real?


Synopsis: Mined diamonds and gemstones can cause a great deal of environmental damage getting them out of the ground, not to mention the horrible working conditions of miners – some just children – have to endure in some of the world’s diamond mines. Lab-grown diamonds and gemstones don’t require dangerous working conditions, and they’re made with just a fraction of the environmental impact of mined gems. But are those stones grown in laboratory really diamonds? Do they look the same as the mined versions? We talk to a spokesperson for lab-grown diamonds and to a geologist about the issue.

Host: Marty Peterson. Guests: T.J. Walker, spokesperson for Pure Grown Diamonds, manufacturers of lab-grown diamonds; Marcia Bjornerud, Professor of Geology, Lawrence University, Appleton, WI.
