Writing today in the International Journal of Liability and Scientific Enquiry, Patrick Kierkegaard of the University of Essex, England, suggests that there is scant scientific evidence that video games are anything but harmless and do not lead to real world aggression. Moreover, his research shows that previous work is biased towards the opposite conclusion.
Using a convenient and flexible method for creating twin light beams, researchers have produced "quantum images," pairs of information-rich visual patterns whose features are "entangled," or inextricably linked by the laws of quantum physics.

Sometimes you just can't believe your eyes. This week is one of those times.
Using only the computing power of 16 Sony Playstation 3 gaming consoles, scientists at The University of Alabama in Huntsville and the University of Massachusetts, Dartmouth, have solved a mystery about the speed at which vibrating black holes stop vibrating.
UCLA scientists have found that for computer-savvy middle-aged and older adults, searching the Internet triggers key centers in the brain that control decision-making and complex reasoning. The findings demonstrate that Web search activity may help stimulate and possibly improve brain function.

Bed bugs, once nearly eradicated in the built environment, have made a big comeback recently, especially in urban centers such as New York City. In the first study to explain the failure to control certain bed bug populations, researchers show that some of these nocturnal blood suckers have developed resistance to pyrethroid insecticides
