Earths ice-covered polar regions help to keep our climate cool and hold tremendous amounts of fresh water locked up in their glaciers, ice caps, and ice sheets. The ice contained in these vast freshwater reservoirs is the equivalent of nearly 220 feet of sea level. However, when most people think of polar ice, they usually do not think of Canada, the location of only a small percentage of the Arctics polar land ice.
During the research campaigns, first in 1995 and then in 2000, Abdalati and his colleagues flew the NASA P-3 aircraft over the Canada Arctic Archipelago. Shown here is the location map of the 2000 flight lines (repeat surveys of the 1995 lines) where flights were conducted out of Pangnirtung, Clyde River, Grise Fiord, and Eureka. Weather station data used in this analysis were from Eureka, Alert, Resolute, Clyde River, Iqaluit, Egedesminde, and Dewar Lakes. Click on image for a larger view.

Recent research conducted by NASA scientists has revealed that Canadas ice caps and glaciers have important connections to Earth’s changing climate, and they have a strong potential for contributing to sea level rise.
Canadas Arctic region is covered by approximately 150,000 square kilometers (93,205 square miles) of ice. While this land area is tiny compared to Antarcticas 113.5 million square kilometers (70.5 million square miles), and Greenlands 1.7 million square kilometers (1.05 million square miles) of ice coverage, it is still quite significant. In the next 100 years, melting glaciers and ice caps outside of Greenland and Antarctica, a significant portion of which includes those in Canada, are expected to raise global sea levels by 20 to 40 centimeters (7.9 to 15.8 inches).

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...
