Microwave oven cooks up solar cell material

University of Utah metallurgists used an old microwave oven to produce a nanocrystal semiconductor rapidly using cheap, abundant and less toxic metals than other semiconductors. They hope it will be used for more efficient ...

Novel metamaterial sensor provides bigger picture

Duke University engineers have developed a novel sensor that is more efficient, versatile and cheaper for potential use in such applications as airport security scanners and collision avoidance systems for aircraft, cars ...

Arctic 'Melt Season' Is Growing Longer, New Research Demonstrates

New NASA-led research shows that the melt season for Arctic sea ice has lengthened by an average of 20 days over the span of 28 years, or 6.4 days per decade. The finding stems from scientists' work to compile the first comprehensive ...

Arctic sea ice captured by satellite

The Arctic Ocean is covered by a dynamic layer of sea ice that grows each winter and shrinks each summer, reaching its yearly minimum size each fall. While the 2010 minimum remains to be seen, NASA's Aqua satellite captured ...

Weaknesses in dikes detected by space tech spin-off

A company from one of ESA's Business Incubation Centres has used space technology to develop a scanner to spot weaknesses in dike structures. It is being used to inspect dikes and dams on the Danube river and in the Netherlands. ...

Portable microwave sensors for measuring vital signs

Current medical techniques for monitoring the heart rate and other vital signs use electrodes attached to the body, which are impractical for patients who want to move around. Plasma physicist Atsushi Mase, a scientist at ...
