Béla Fleck is one of the most famous banjo players in the world. He's taken that instrument out of its folk and bluegrass traditions to play pretty much any kind of music, including jazz and pop to classical and reggae. But bluegrass has always been where he comes from — and he's returned to it for his new album, 'My Bluegrass Heart.'Science writer Mary Roach ('Stiff', 'Gulp') explores scenarios where animals are the ones committing "crimes" — and how society deals with it. We talk about bear attacks, drunk elephants, and monkey thieves. Her new book is 'Fuzz: When Nature Breaks the Law.'
