Extreme plasma theories put to the test Posted: 06 Aug 2012 02:13 PM PDT The first controlled studies of extremely hot, dense matter have overthrown the widely accepted 50-year-old model used to explain how ions influence each other's behavior in a dense plasma. The results should benefit a wide range of fields, from research aimed at tapping nuclear fusion as an energy source to understanding the inner workings of stars.

NASA's Curiosity rover caught in the act of landing Posted: 06 Aug 2012 11:19 AM PDT An image from the High Resolution Imaging Science Experiment (HiRISE) camera aboard NASA's Mars Reconnaissance Orbiter captured the Curiosity rover still connected to its 51-foot-wide (almost 16 meter) parachute as it descended towards its landing site at Gale Crater.

Increased productivity, not less energy use, results from more efficient lighting Posted: 06 Aug 2012 10:51 AM PDT Improvements in lighting -- from candles to gas lamps to electric bulbs -- historically have led to increased light consumption rather than lower overall energy use by society, researchers argue in a new article.

Seeing through walls: Laser system reconstructs objects hidden from sight Posted: 06 Aug 2012 10:08 AM PDT Researchers combined bouncing photons with advanced optics to enable them to "see" what's hidden around the corner.

Quantum physics: New insights into the remote control of quantum systems Posted: 06 Aug 2012 10:05 AM PDT Physicists shine new light on the question of the resources required for achieving quantum information processing. The scientists demonstrate that less demanding resources, which are easier to prepare and to control, can be used for quantum-enhanced technologies. In the experiment, researchers achieve remote quantum state preparation without requiring entanglement as a resource.

Touch your philodendron and control your computer: Technology turns any plant into an interactive device Posted: 06 Aug 2012 06:40 AM PDT Any houseplant -- real or artificial -- could control a computer or any digital device with new technology, called Botanicus Interactus.

Hydraulic fracturing poses substantial water pollution risks, analysts say Posted: 06 Aug 2012 06:39 AM PDT Researchers find multiple potential threats to water sources posed by hydraulic fracturing as the jobs-producing practice expands.

Microswimmers: Micron-scale swimming robots could deliver drugs and carry cargo using simple motion Posted: 06 Aug 2012 06:39 AM PDT Researchers have used complex computational models to design micro-swimmers that could overcome the challenges of swimming at the micron scale. These autonomous micro-robots could carry cargo and navigate in response to stimuli such as light.

Information advantage gained from surprising quantum source Posted: 06 Aug 2012 05:51 AM PDT New research lends hope that a phenomenon called quantum discord could be harnessed to bring quantum technologies within easier reach than expected.

NASA's new Mars rover sends higher-resolution image Posted: 06 Aug 2012 04:44 AM PDT About two hours after landing on Mars and beaming back its first image, NASA's Curiosity rover transmitted a higher-resolution image of its new Martian home, Gale Crater. Mission Control at NASA's Jet Propulsion Laboratory in Pasadena, Calif., received the image, taken by one of the vehicle's lower-fidelity, black-and-white Hazard Avoidance Cameras -- or Hazcams.
