Power plant emissions verified remotely at Four Corners sites
Los Alamos NM (SPX) May 23, 2014 -
Air pollution and greenhouse gas emissions from two coal-fired power plants in the Four Corners area of northwest New Mexico, the largest point source of pollution in America, were measured remotely by a Los Alamos National Laboratory team.
Led by Laboratory senior scientist Manvendra Dubey, the study is the first to show that space-based techniques can successfully verify international re ...

New method for propulsion in fluids
Boston MA (SPX) May 23, 2014 -
Researchers at MIT have discovered a new way of harnessing temperature gradients in fluids to propel objects. In the natural world, the mechanism may influence the motion of icebergs floating on the sea and rocks moving through subterranean magma chambers.
The discovery is reported this week in the journal Physical Review Letters by associate professor of mechanical engineering Thomas Peac ...

NIST chip produces and detects specialized gas for biomedical analysis
Washington DC (SPX) May 23, 2014 -
A chip-scale device that both produces and detects a specialized gas used in biomedical analysis and medical imaging has been built and demonstrated at the National Institute of Standards and Technology (NIST). Described in Nature Communications,* the new microfluidic chip produces polarized (or magnetized) xenon gas and then detects even the faintest magnetic signals from the gas.
Polariz ...

Not all diamonds are forever
Houston TX (SPX) May 23, 2014 -
Images taken by Rice University scientists show that some diamonds are not forever. The Rice researchers behind a new study that explains the creation of nanodiamonds in treated coal also show that some microscopic diamonds only last seconds before fading back into less-structured forms of carbon under the impact of an electron beam.
Billups and Yanqiu Sun, a former postdoctoral researcher ...

NCNR neutrons highlight possible battery candidate
Washington DC (SPX) May 23, 2014 -
Analysis of a manganese-based crystal by scientists at the National Institute of Standards and Technology (NIST) and the Massachusetts Institute of Technology (MIT) has produced the first clear picture of its molecular structure. The findings could help explain the magnetic and electronic behavior of the whole family of crystals, many of which have potential for use in batteries.
The famil ...

Stanford, MIT scientists find new way to harness waste heat
Stanford CA (SPX) May 23, 2014 -
Vast amounts of excess heat are generated by industrial processes and by electric power plants. Researchers around the world have spent decades seeking ways to harness some of this wasted energy. Most such efforts have focused on thermoelectric devices - solid-state materials that can produce electricity from a temperature gradient - but the efficiency of such devices is limited by the availabil ...

BAE Systems, Airbus Defense form alliance
Arlington, Va. (UPI) May 21, 2013 -
BAE Systems and Airbus Defense and Space have partnered to produce and market geospatial intelligence products and solutions.
The geospatial intelligence, or GEOINT, products developed will leverage satellite data collected by Airbus Defense and Space's TerraSAR-X and TanDEM-X radar satellites.
"The Airbus Defense and Space radar satellite missions are collecting data of unpreced ...
