The sex sounds flies make can lead to a violent death -- luring predator bats to their love nests while their defenses are down, a report said Monday.
Researchers who studied a small community of flies and bats in a cowshed near Marburg, Germany, found that the insects' chances of becoming dinner were dramatically higher while copulating.Full Story
In the debate over natural gas drilling, the companies are often the ones accused of twisting the facts. But scientists say opponents sometimes mislead the public, too.
Critics of fracking often raise alarms about groundwater pollution, air pollution, and cancer risks, and there are still many uncertainties. But some of the claims have little — or nothing— to back them.Full Story
