Diabetes Rising; Ten Hills Farm; Teen Voices

In his new book, "Diabetes Rising," medical journalist Dan Hurley documents a seemingly inexplicable cluster of type 1 diabetes cases in Weston, Mass. This sudden uptick in Boston's wealthiest suburb raises big questions about socioeconomics, lifestyle, and the cause of the disease. Dan Hurley joins us live from NYC.

Also, journalist C. S. Manegold's latest book, "Ten Hills Farm," blows away the popular notion that Boston kept its hands clean of the slave trade.  As Black History Month wraps up, we talk with Manegold and visit Ten Hills Farm in Medford, where five generations of powerful New England families held slaves.
