S. Tariq Ahmad (biology) and Jennifer Liao ’15, with Joseph A. Seggio, have published the article, “Mutations in the circadian gene period alter behavioral and biochemical responses to ethanol in Drosophila,” in the journal Behavioural Brain Research. The article, reporting results of Liao’s senior thesis research, shows faster ethanol-induced sedation and slower recovery with age. The findings also suggest that mutations in this gene influence ethanol-induced behavior and ethanol metabolism in Drosophila.
