A team of scientists at the University of Wales recently revealed that they've developed a new type of bomb-detecting sensor using nanotechnology, branding the tech with the too-cute-for-its-own-good "nanodog" moniker. As with most things nanotech, the nanodog promises to allow for devices to be both smaller and more effective than current technologies, apparently able to detect explosives at levels in the one part per trillion range. And, like it's K-9 counterpart, the sensor can apparently detect explosives even if they're concealed, which should no doubt lead to less invasive, and hopefully speedier airport searches in the future. Of course, depending on who you ask, the nanodog might not exactly turn out to be man's best friend.
