Caring for more than 180,000 Sudanese refugees gathered in the desert landscape of eastern Chad, the United Nations High Commissioner for Refugees has begun using satellite data to identify hidden water resources and site new camps.
By permission of the Chadian government, there are currently nine United Nations High Commissioner for Refugees (UNHCR) camps in place. UNHCR has transferred the vast majority of the refugees from the volatile border to the camps. Thousands more have come on their own from the border, further straining already scarce resources. And concerns remain high that more refugees could still flee from Darfur.
A huge volume of people has to be kept supplied with food, water and basic necessities in this remote region, linked by inadequate roads made worse by the onset of the rainy season. The greatest single need is water. UNHCR standards call for 15 litres of water per person per day, but some camps in eastern Chad are still below this minimum requirement.

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...
