Why Wyoming is getting another world-class supercomputerThe National Center for Atmospheric Research (NCAR) has announced it has decided on a new supercomputer for 2017. The new, upgraded supercomputer will offer more power and the potential for greater insights into the climate and environment.
Scientists invent lithium-ion battery that's less likely to explode on youResearchers at Stanford University used nanotechnology to solve a longstanding problem among electrically-driven devices, from airplanes to so-called hoverboards.
First LookAs comet 67P cools, one last-ditch effort to call PhilaePhilae, the first probe to study a comet up close, has not communicated with Earth in months. Astronomers say they'll make one last effort to call, before the probe travels with the comet too far away from the sun's heat to even turn on.
