Lush or lightweight?

10-31-2007 · EurekAlert!

Some fruit flies can drink others under the table. Now, scientists at North Carolina State University have a few more genetic clues behind why some flies are more sensitive to alcohol than others. And the results might lead to more knowledge about alcoholism in humans.
