A team of theoretical physicists working at CERN and the Technion Institute of Technology in Israel has developed a theory to account for the mysterious gamma ray bursts that come from the depths of the Universe. According to their ideas, gamma ray bursts are linked to supernovae, the cataclysmic explosions of massive stars at the end of their lives. When a new gamma ray burst (GRB 030329) was seen on March 29 2003, the CERN-Technion team immediately predicted that light from a supernova would first become clearly visible on Earth from the same direction on April 8. And so it did (SN 2003dh). This is the first time that scientists have predicted the exact day of observation of a supernova. Until now, they have not been able to predict the supernova explosion time to an accuracy better than a million years!
Although particle physics and cosmology study opposite extremes - particle physics is a study of the tiny building blocks of nature, cosmology the large scale workings of the Universe - the questions they ask are intimately linked. This latest result is a concrete example of the interplay between the two fields.

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...
