At 32 degrees Fahrenheit, or 0 Celsius, ice changes to water. This simple, unique fact dominates the climate in Earths polar regions. Using satellites to detect changes over time, NASA researchers and NASA-funded university scientists have found that Earths ice cover is changing rapidly near its poles. Recent studies point to new evidence of relationships between climate warming, ice changes and sea level rise.
Two researchers from NASA Goddard Space Flight Center (GSFC), Greenbelt, Md., and a glaciologist from the University of Colorados National Snow and Ice Data Center, Boulder, Colo., will discuss new findings related to Earths ice cover at a press conference on Dec. 14 at the 2004 meeting of the American Geophysical Union in San Francisco, Calif.
Waleed Abdalati, a NASA GSFC researcher, has worked with colleagues on a slew of recent papers on glaciers and ice sheets in the Northern Hemisphere. Bill Krabill of NASA Wallops Space Flight Center, Wallops Island, Va., Abdalati and others calculated that Greenlands contributions to sea level rise nearly doubled in recent years, from 0.13 millimeters (mm) (.005 inches) per year in the mid 1990s, to 0.25 mm (.01 inches) per year from 1997 to 2003. Krabills study measured steady thinning in the regions lower elevations near the coasts.

On January 15, 2009, Chesley B. Sullenberger was celebrated world-wide: after the two engines had failed due to bird strike, he and his flight crew succeeded after a glide flight with an Airbus A320 in ditching on the Hudson River. All 155 people on board were saved.

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...
