Seriously. From the NYT:
To test the relationship between stress and alcohol in fruit flies, researchers at the University of California, San Francisco, allowed one group of male flies to mate freely with available virgin females. Another group of male flies had the opposite experience: the females they mingled with had already mated, and were thus indifferent to any approach.I wonder what the fruit flies would do if you offered them 72 virgins?
After four days, the flies in both groups fed in glass tubes outfitted with four straws, two providing a regular diet of yeast and sugar and two containing yeast, sugar and 15 percent alcohol. Fruit flies as a rule will, like many humans, develop a taste for alcohol and, in time, a preference for the 15 percent solution. But the rejected flies drank a lot more on average, supping from the spiked mixture about 70 percent of the time, compared with about 50 percent for their sexually sated peers.
