Laser the size of a virus particle: Miniature laser operates at room temperature and defies the diffraction limit of light Posted: 05 Nov 2012 02:23 PM PST A research team has found a way to manufacture single laser devices that are the size of a virus particle and that operate at room temperature. These plasmonic nanolasers could be readily integrated into silicon-based photonic devices, all-optical circuits and nanoscale biosensors.

Revolutionary type of gel discovered Posted: 05 Nov 2012 01:12 PM PST Controlling and modifying at will the transparency, electrical properties, and stiffness of a gel are among the promises of new research by scientists in Switzerland. Their discovery marks an important step for materials used in healthcare, high-tech, and the cosmetics industry.

Common math standards supported with new study Posted: 05 Nov 2012 11:04 AM PST A new study analyzing the previous math standards of each U.S. state provides strong support for adoption of common standards, which US students desperately need to keep pace with their counterparts around the globe, a scholar argues.

High-strength material advancements may lead to new, life-saving steel Posted: 05 Nov 2012 11:02 AM PST Engineers have been working to create advanced materials with high-yield strength, fracture toughness and ductility. Their efforts have led to the development of a new material consisting of bainitic steels and austempered ductile iron that has all these characteristics, ultimately resisting fatigue that can cause fractures in materials often with catastrophic consequences.

Computers 'taught' to ID regulating gene sequences Posted: 05 Nov 2012 11:01 AM PST Researchers have succeeded in teaching computers how to identify commonalities in DNA sequences known to regulate gene activity, and to then use those commonalities to predict other regulatory regions throughout the genome. The tool is expected to help scientists better understand disease risk and cell development.

Gravitmetric sensors for the real world Posted: 05 Nov 2012 10:04 AM PST Researchers have developed gravimetric sensors which are not affected by temperature.

Build your own home theater for full-blast entertainment with 'Virtual Sound Ball' Posted: 05 Nov 2012 10:04 AM PST Scientists have developed audio rendering systems, "Virtual Sound Ball" and "Spatial Equalizer" that will considerably improve the current 3-D audio effects technology.

Crystals for efficient refrigeration: Can pump or extract heat, even on the nanoscale, for use on computer chips Posted: 05 Nov 2012 08:46 AM PST Researchers have discovered a new efficient way to pump heat using crystals. The crystals can pump or extract heat, even on the nanoscale, so they could be used on computer chips to prevent overheating or even meltdown, which is currently a major limit to higher computer speeds.

Electron microscopes with a twist: Vortex beams, rotating like a tornado, offer new possibilities for electron microscopy Posted: 05 Nov 2012 07:08 AM PST Vortex beams, rotating like a tornado, offer completely new possibilities for electron microscopy.  A method of producing extremely intense vortex beams has been discovered.

Vehicles, roadways 'talk' in efforts to improve traffic safety Posted: 05 Nov 2012 06:26 AM PST One day, your auto and the roadway will be in constant communication and able to suggest route changes to avoid accidents, construction, and congestion; coordinate your vehicle with signal lights, other vehicles, and lane markers; and let you know where you can park. Right now, a fleet of instrumented vehicles are testing these systems on two instrumented test beds -- one in Northern Virginia and one in Southwestern Virginia.

Salting roads may damage steel-reinforced concrete structures Posted: 05 Nov 2012 05:15 AM PST Swedish scientists have studied models to help road and bridge maintenance engineers work out how much damage salting the roads in winter might cause to steel-reinforced concrete structures.
