Including the atmospheric effects from volcanic eruptions in general circulation models may be the most important factor in improving the accuracy of long-term climate simulations. Vyushin et al. analyzed general circulation model estimates for the 20th century climate and found that volcanic eruptions, rather than the manmade effects from increasing greenhouse gas and aerosol levels, are the most significant factor in determining long-range correlations of surface air temperature.
The authors tested more than 30 land and oceanic sites indicative of global climate change, using a full range of manmade and natural climate change factors, including the effects from enhanced greenhouse gases, aerosols, ozone, solar radiation, and volcanic eruptions, and found that the simulations containing volcanic effects most closely matched the observed long-term behavior of surface temperatures, which is a vital scaling factor used in climate model predictions.

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...
