flies on the rim of a beer bottle Ever wondered why flies are attracted to beer? Entomologists at University of California, Riverside, have, and offer an explanation. They report that flies sense glycerol that yeasts make during fermentation.

Once a fly has settled on beer, Gr64e detects glycerol and transmits this information to the fly's neurons. Full Story
