This illustration shows the new aperture design (left) with two layers of silver separated by another of silicon dioxide. The structure focuses light in a novel way to trap particles smaller than ever before. The focused beams are shown in the illustration on the right.

TechAndComputer (Dec. 4, 2012) A microscale technique known as optical trapping uses beams of light as tweezers to hold and manipulate tiny particles. Stanford researchers have found a new way to trap particles smaller than 10 nanometers -- and potentially down to just a few atoms in size -- which until now have escaped light's grasp.
To grasp and move microscopic objects, such...

TechAndComputer (Dec. 4, 2012) If you think having your phone identify the nearest bus stop is cool, wait until it identifies your mood. New research by a team of engineers at the University of Rochester may soon make that possible. At the IEEE Workshop on Spoken Language Technology on Dec. 5, the researchers will describe a new computer program that gauges human feelings through speech, with substantially greater accuracy than existing approaches.
Surprisingly, the program...

TechAndComputer (Dec. 3, 2012) Scientists at the U.S. Department of Energy's (DOE) Ames Laboratory have discovered new ways of using a well-known polymer in organic light emitting diodes (OLEDs), which could eliminate the need for an increasingly problematic and breakable metal-oxide used in screen displays in computers, televisions, and cell...

TechAndComputer (Nov. 28, 2012) Researchers from North Carolina State University and the University of Oregon have found a way to exploit cloud-based Web browsers, using them to perform large-scale computing tasks anonymously. The finding has potential ramifications for the security of "cloud browser" services.
At issue are cloud browsers, which create a Web interface in the cloud so that computing is done there rather than on a user's machine. This is particularly useful for...
