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.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
