Carl Zimmer is a science columnist for the ‘New York Times.’ His new book, ‘She Has Her Mother’s Laugh,’ is about the broader implications of genetic research and testing. Zimmer tells Terry Gross about genetically modified mosquitoes that are resistant to malaria, how genetic testing was used in the Golden State Killer case, and what he learned about his family history from having his entire genome sequenced. Also, Maureen Corrigan reviews two mysteries she thinks would make for terrific summer reading.
