Sex-Deprived Fruit Flies, Like Humans, Turn to Booze

A recent study at The University Of California in San Francisco found that male fruit flies deprived of sex drank twice their bodyweight (which really can’t be too much, right?) in alcohol infused fruit while sexed-up flies drank hardly any.

When a fly is deprived of sex, a brain chemical called neuropeptide F–which plays a part in the internal rewards system–decreases, and drinking alcohol restores that chemical. Apparently, we too have neuropeptides (though ours are neuropeptide Y not F), which when decreased in humans have been found to inhibit alcohol intake as well as over-eating.

What’s more depressing than realizing you drink because you’re sex deprived? Realizing you have the same brain chemicals as a fruit fly.
