Good diet, proper exercise help protect astronauts’ bones (August 24, 2012) -- Eating right and exercising hard in space helps protect International Space Station astronauts' bones, a finding that may help solve one of the key problems facing future explorers heading beyond low Earth orbit. ... > full story

Microwave ovens may help produce lower cost solar energy technology (August 24, 2012) -- The same type of microwave oven technology that most people use to heat up leftover food has found an important application in the solar energy industry, providing a new way to make thin-film photovoltaic products with less energy, expense and environmental concerns. ... > full story

Boston subway system to be used to test new sensors for biological agents (August 24, 2012) -- The Department of Homeland Security’s Science and Technology Directorate has scheduled a series of tests in the Boston subways to measure the real-world performance of new sensors recently developed to detect biological agents within minutes. ... > full story

Superior fuel cell material developed (August 24, 2012) -- Using a mixture of gold, copper and platinum nanoparticles, researchers have developed a more powerful and longer lasting fuel cell material. ... > full story

Flat lens offers a perfect image (August 24, 2012) -- Applied physicists have created an ultrathin, flat lens that focuses light without imparting the distortions of conventional lenses. It operates at telecom wavelengths -- i.e., those used for fiber-optics -- and is scalable to a wider range. ... > full story

Mars surface data: ChemCam laser first analyses yield beautiful results (August 24, 2012) -- Scientists squeezed in a little extra target practice after zapping the first fist-sized rock that was placed in the laser's crosshairs last weekend. Much to the delight of the scientific team, the laser instrument has fired nearly 500 shots so far that have produced strong, clear data about the composition of the Martian surface. ... > full story

Simplified approach for high-power, single-mode lasers (August 24, 2012) -- Researchers have developed a new resonator that creates the purest, brightest, and most powerful single-mode quantum cascade lasers yet at the eight-12 micron range, a wavelength of great interest for both military and industrial use. ... > full story

Modeling metastasis (August 24, 2012) -- A technique used by animators helps scientists model how cancer cells enter the bloodstream. ... > full story

Invention will strike a chord with musicians (August 24, 2012) -- Digital software and hardware is set to revolutionize the music industry around the world. ... > full story

Joining 'unjoinable' materials: New polymer linking technology based on nano crystals (August 24, 2012) -- Ever tried to paint on top of silicone? After a few hours, the paint will peel off. Annoying. Silicone is a so-called low surface energy polymer, well known from flexible baking forms: A synthetic material that has an extremely low adhesion or "stickiness." Teflon is similarly non-sticky and well known from frying pans. Researchers have now developed the first technology which is capable of joining these two "unjoinable" materials. The technology applies passive nano-scaled crystal linkers as internal staples. ... > full story

Physicists search for hidden magnetic states (August 24, 2012) -- Physicists have used the new high magnetic-field beamline at Diamond Light Source, the UK's national synchrotron facility, to search for 'hidden magnetic states'. If found, they will provide important confirmation of a theoretical model, which could have important applications in magnetic data storage. ... > full story

Scientists investigate using artificial intelligence for next-generation traffic control (August 24, 2012) -- Researchers are investigating the application of artificial intelligence (AI) technology for controlling traffic lights. The development of artificial intelligence-based approaches to junction control is one of many new and promising technologies that can make better use of existing urban and road capacity, while reducing the environmental impacts of road traffic. ... > full story
