Major Players: Lasker Award Winners, a Master Art Forger, Race and Theater

Two of this year’s Lasker Award winners, Mary-Claire King and Alim Louis Benabid, tell us about their research and medical discoveries. Kenneth Lonergan discusses his critically acclaimed play “This Is Our Youth,” along with Kieran Culkin, one of its stars. Jennifer Grausman and art forger Mark Landis talk about his skill at creating forged paintings. He’s the subject of the documentary called “Art and Craft.” Plus: NPR’s Michel Martin and playwrights Kristoffer Diaz and Ayad Akhtar look at the role of race in theater, and how race is explored onstage.
