Chinas rainy season has led to serious flooding in the north-east and south of the country. A joint Chinese-European team is gathering Envisat radar imagery of the developing situation to give the authorities a way to swiftly assess affected areas and plan their responses.
Summer flooding is nothing new in these regions of the Peoples Republic of China (PRC), though this year it is proving particularly severe, with more than 800 casualties countrywide and 2.45 million people forced to evacuate their homes. However this seasons flooding is being monitored in near real-time by ESAs Envisat Advanced Synthetic Aperture Radar (ASAR) sensor, which can acquire imagery in both day and night and in all weathers.
This activity is taking place as part of ESAs Dragon Programme of cooperation with the National Remote Sensing Centre of China (NRSCC) within the Ministry of Science and Technology of the PRC. These Envisat images are a means for the authorities to identify floodwater extent and coordinate mitigation efforts, and should be a foretaste of things to come – next season the aim is that a full near real-time monitoring service should be operational.

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...
