First, science gives us a good excuse to booze the night away. Now, a new study justifies sad drinking. If a male fruitfly’s attempts to mount a fly girl don’t work — “nuzzling her genitals, tapping her abdomen and singing with his wings” — he goes off to find alcohol. Sex and drinking both reward its wee brain with neuropeptide F (NPF), similar to NPY in humans. So, scientist cads, is it fun to watching the poor buzz-bro fail and flounder, like your own private insectoid Jersey Shore? (Photo: Roy Niswanger/Flickr)
