derekmead writes "How’s this for hilariously depressing: male fruit flies who have their sexual advances rejected drink alcohol far more heavily than males who are regularly having sex.
Yes, you read that right. New research from a team at UC San Francisco has discovered that a tiny molecule in flies’ brains, called neuropeptide F, acts as a link between sexual rejection and excessive drinking. A similar molecule, neuropeptide Y, exists in humans, and as such the research helps shed light on what triggers human addiction."
