He and Andrey Finegersh, an MD/PhD student in his lab, decided to try a slightly different tack. “We thought that maybe in alcoholics, drinking a lot would cause some changes in what controls the genes—and that is what gets passed down to the next generation,” says Homanics. The findings from the resulting study were published in PLOS ONE in June.
