Duke University's Nancy Andrews and her daughter, Camille Mathey-Andrews, appeared in yesterday's The News & Observer, discussing how they spend time together — in the lab. On Saturdays, Camille, who is interested in pursuing medical studies, has joined her mother in the lab to isolate and compare DNA samples from their family members. "It started as a couple of hours, and then it turned into the whole day," Andrews, tells The News &Observer.
