Hours spent at the video gaming console not only train a player's hands to work the buttons on the controller, they probably also train the brain to make better and faster use of visual input, according to Duke University researchers.

This is a scanning electron micrograph of Sulfolobus solfataricus cells infected with STIV, showing pyramid-like structures on the surface of the cell. Biologists from Indiana University and Montana State University have discovered a striking connection between viruses such as HIV and Ebola and viruses that infect organisms called archaea that grow in volcanic hot springs. Despite the huge difference in environments and a 2 billion year evolutionary time span between archaea and humans, the viruses hijack the same set of proteins to break out of infected cells.
