3D Fingerprint Scans May Be the Ultimate Security Tool

Compared to a password that’s either too simple to be effective, or too hard to remember, a fingerprint is a great security tool. But they’re not infallible, in fact, they can be easily replicated with just a photo. So researchers are taking fingerprint security one step further and scanning them in three dimensions. »7/01/15 10:15am7/01/15 10:15am

Rough Nano-Wires Hold the Secret to Efficient Heat to Electricity Conversion

The latest edition of Nature magazine details a new method scientists have derived for converting heat energy into electricity, using silicon to instigate the conversion. Researchers have more investigations to carry out, but if preliminary findings are indicative of what is to come, appliances that charge using your… »1/13/08 7:25pm1/13/08 7:25pm

World's Smallest Radio Is Just Atoms Wide, Still Needs AAA Battery

University of California researcher Chris Rutherglen shows off a radio made of carbon nanotubes, measuring "a few atoms across," that's 1,000 times smaller than today's radio technology. »10/18/07 4:24pm10/18/07 4:24pm
