Computer security systems may one day get a boost from quantum physics, as a result of recent research into a “one-shot” memory unit, whose contents can be read only a single time. The research, by Yi-Kai Liu from the National Institute of Standards and Technology, is being presented this week at Princeton’s Innovations in Theoretical […]
Earlier this year, China deliberately destroyed one of its own weather satellites in orbit; an act which some analysts suggested could re-ignite the techno-political brouhaha about armaments in space. But two researchers believe that satellite-killing capability is not solely the preserve of super-powers, and is well within the reach of amateurs. Adrian Gheorghe and Dan […]
Broadband communications may be about to get a whole lot faster and cheaper, thanks to high-altitude platforms (HAPs) that can relay wireless and optical communications to remote areas. The revolutionary CAPANINA project is the brainchild of a consortium drawn from Europe and Japan and led by the University of York, UK. The group will converge […]
