Explorer Sarah Marquis talks about her recent 10,000 mile solo hike from Siberia to Australia. Muriel Barbery discusses her latest novel which tells the story of two young girls who share a gift for communicating with invisible forces and spirits. Since the leak at Indian Point nuclear plant earlier this month, radioactivity levels reportedly rose nearly 65,000% in one well.
