By pairing a sleek new air sampler designed at the University Corporation for Atmospheric Research (UCAR) with a diode laser from SpectraSensors, Inc., researchers have hit on a technology that can capture highly accurate atmospheric water vapor data during routine commercial flights. The data will benefit researchers and forecasters, who need more frequent, accurate measurements at various altitudes worldwide to improve weather forecasts and monitor climate change.
Currently water vapor data is gathered by an older style of sensor using a thin-film capacitor. These sensors are launched on weather balloons every 12 hours from stations around the country. Satellites also gather water vapor data, but at low vertical resolution. The WVSS II aboard commercial flights will gather data more often, at higher vertical resolution, and at lower cost than satellites and balloons.
"Water vapor sounds boring," says recently retired UCAR scientist Rex Fleming, who designed the innovative air sampler, "but its essential to almost everything that happens in the atmosphere." Better water vapor data from around the U.S. and the world can improve forecasts of thunderstorms, microbursts, turbulence, fog, ceiling visibility, rotating wakes from other aircraft, snow and ice storms, and year-round precipitation, he says.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
