World leaders should look to existing international law on the use of force to address the threat of space becoming ever more militarized, a new study shows.

In new images, scientists have gotten the close look yet at Sagittarius C—a "stellar nursery" where clouds of gas and dust have collapsed to form thousands of new stars.

Scientists should experiment with creative ways of communicating their work to inspire action to protect the natural world, researchers say.  

Most people donning virtual reality (VR) goggles are seeking the thrill of being immersed in a fictitious video game world. But some are donning them for an entirely different experience: to help researchers identify those most at risk of developing Alzheimer’s disease. As will be presented today at the annual conference of the Cognitive Neuroscience Society (CNS) in Boston, Mass., cognitive neuroscientists are increasingly turning to VR technology to develop innovative ways to assess cognitive decline. They are finding significant age-related and disease-related differences in how individuals can navigate and locate objects within a VR space, in some cases linking cognitive impairments to build up of Alzheimer’s proteins in the brain.
