Fly Sex, or: How to Save the Earth

Scientists have discovered a way to make flies utterly promiscuous.

Well, that is all very well and good if you aspire to be a promiscuous fly, but I've long thought that transferring lightning bug genes into people would be far more effective for personkind.

Only lightning bug females blink, and only when they are ready to mate. Just think of how much money and booze ie precious natural resources ie It Would Preserve Gaiea would be saved by young men when they went prowling bars: they'd only have to buy drinks for the young ladies whose bottoms were blinking.
