Scientists create sexual tsunami
Even leaving aside the weird metaphor the headline writer chose, this is an odd article. To summarize, scientists bred a fruit fly that lacked the gene to produce a characteristic pheromone, and to their surprise found that it actually made the flies sexually irresistible to other fruit flies, including ones of the same gender. Even flies of other species were interested.
"Lacking these chemical signals eliminated barriers to mating," Prof Levine said.
This seems like a lot of trouble to get fruit flies all worked up. In the human world, we just get a couple of kegs of beer.
