New tool aims to ensure software security policies reflect user needs Posted: 30 Oct 2012 06:03 PM PDT Researchers have developed a new natural language processing tool that businesses or other customers can use to ensure that software developers have a clear idea of the security policies to be incorporated into new software products.

'Ordered' catalyst boosts fuel cell output at lower cost Posted: 30 Oct 2012 02:32 PM PDT Fuel cells, which convert fuel directly into electricity without burning it, promise a less polluted future where cars run on pure hydrogen and exhaust nothing but water vapor. But the catalysts that make them work are still "sluggish" and worse, expensive. A research team has taken an important step forward with a chemical process that creates platinum-cobalt nanoparticles with a platinum enriched shell that show improved catalytic activity.

Materials scientists make additive-free battery electrodes with nanoparticles Posted: 30 Oct 2012 02:31 PM PDT Materials scientists have developed a simple, robust way to fabricate carbon-free and polymer-free, lightweight colloidal films for lithium-ion battery electrodes, which could greatly improve battery performance.

Smart as a bird: Flying rescue robot will autonomously avoid obstacles Posted: 30 Oct 2012 02:30 PM PDT Researchers have created an autonomous flying robot that is as smart as a bird when it comes to maneuvering around obstacles.

First direct detection sheds light on dark galaxies Posted: 30 Oct 2012 01:12 PM PDT Three lead members of an international science team provide insight into the first direct detection of dark galaxies.

Mars like Hawaii? NASA rover's first soil studies help fingerprint Martian minerals Posted: 30 Oct 2012 12:42 PM PDT NASA's Mars rover Curiosity has completed initial experiments showing the mineralogy of Martian soil is similar to weathered basaltic soils of volcanic origin in Hawaii. The minerals were identified in the first sample of Martian soil ingested recently by the rover. Curiosity used its Chemistry and Mineralogy instrument (CheMin) to obtain the results, which are filling gaps and adding confidence to earlier estimates of the mineralogical makeup of the dust and fine soil widespread on the Red Planet.

Scattering of hydroxyl radicals measured with velocity-map imaging Posted: 30 Oct 2012 11:28 AM PDT Scientists are using velocity-map imaging to examine inelastic scattering of hydroxyl radicals.

New MRI technique allows detailed imaging of complex muscle structures and muscle damage Posted: 30 Oct 2012 11:27 AM PDT Scientists have developed a technique that allows detailed 3-D imaging of complex muscle structures of patients. It also allows muscle damage to be detected very precisely. This new technique opens the way to much better and more patient-friendly diagnosis of muscular diseases. It also allows accurate, non-invasive muscle examinations among top athletes.

Exoskeleton of advanced design promises new degree of independence for people with paraplegia Posted: 30 Oct 2012 07:13 AM PDT Engineers have developed a powered exoskeleton that enables people with severe spinal cord injuries to stand, walk, sit and climb stairs. Its light weight, compact size and modular design promise to provide users with an unprecedented degree of independence.

New technique connects multi-walled carbon nanotubes Posted: 30 Oct 2012 06:36 AM PDT Using a new method for precisely controlling the deposition of carbon, researchers have demonstrated a technique for connecting multi-walled carbon nanotubes to the metallic pads of integrated circuits without the high interface resistance produced by traditional fabrication techniques.

The hunt for electron holes: A molecular glance on solar water splitting Posted: 30 Oct 2012 03:22 AM PDT Hydrogen production by solar water splitting in photoelectrochemical cells (PEC) has long been considered the holy grail of sustainable energy research. Iron oxide is a promising electrode material. Scientists have now gained in-depth insights into the electronic structure of an iron oxide electrode – while it was in operation. This opens up new possibilities for an affordable hydrogen production from solar energy.
