Levitation: Droplets surfing on sound waves Posted: 16 Jul 2013 11:07 AM PDT Researchers are able to make objects such as particles and liquid droplets fly in mid-air by letting them ride on acoustic waves. For the first time, they have been able to also control the movement of objects, merge droplets, letting them react chemically or biologically and even rotate a toothpick in the air.

New nanoscale imaging method finds application in plasmonics Posted: 16 Jul 2013 10:22 AM PDT Researchers have shown how to make nanoscale measurements of critical properties of plasmonic nanomaterials, the specially engineered nanostructures that modify the interaction of light and matter for a variety of applications including sensors, cloaking (invisibility), photovoltaics and therapeutics.

Eye-tracking could outshine passwords if made user-friendly Posted: 16 Jul 2013 10:22 AM PDT Engineers found in a recent study that the user's experience could be key to creating an authentication system that doesn't rely on passwords.

Broadband photodetector for polarized light Posted: 16 Jul 2013 10:21 AM PDT Using carpets of aligned carbon nanotubes, researchers have created a solid-state electronic device that is hardwired to detect polarized light across a broad swath of the visible and infrared spectrum.

New model to improve vehicle-to-vehicle communication for 'intelligent transportation' Posted: 16 Jul 2013 09:00 AM PDT Imagine a transportation system where vehicles communicate directly with each other in real time, giving drivers warnings about traffic delays, allowing a single driver to control multiple vehicles or routing vehicles around hazardous road conditions. Those are all aspects of the "intelligent transportation" concept. And researchers have developed a model to improve the clarity of the vehicle-to-vehicle transmissions needed to make that concept a reality.

Where's Waldo? A new alien-like species discovered off California Posted: 16 Jul 2013 09:00 AM PDT After nearly 25 years of searching, three scientists have finally found Waldo. No, not the loveable bespectacled character in children's picture books, but rather an unusual clam discovered off the coast of California and British Columbia.

New thermocell could harvest 'waste heat' from power stations and even vehicle exhaust pipes Posted: 16 Jul 2013 06:27 AM PDT Harvesting waste heat from power stations and even vehicle exhaust pipes could soon provide a valuable supply of electricity.

New findings on makeup of universe may spawn research Posted: 16 Jul 2013 06:26 AM PDT New areas of extragalactic study may emerge from research by astrophysicists using data from the Chandra Space Telescope to conclude that baryons making up all visible matter – once thought to be missing from clusters – are present in the expected ratios in large, luminous clusters.

A close Bond: How the CIA exploited 007 for gadget ideas and public relations Posted: 16 Jul 2013 04:59 AM PDT The real-life CIA copied outlandish gadgets from Goldfinger and From Russia With Love, according to an analysis of declassified letters and interviews revealing the bond between Ian Fleming and Allen Dulles.
