Business-as-usual approach threatens world energy supplies and environment, but affordable, effective solutions appear within reach
Implementing a plan to keep rising carbon dioxide levels from reaching potentially dangerous levels could cost less than 1 percent of gross world product as of 2050, a cost that is well within reach of developed and developing nations alike. However, without simultaneous progress in the way energy is found, transformed, transported and used, the world is in danger of facing a severe energy crisis sometime within the next century.
Those are the conclusions of a report by Klaus S. Lackner and Jeffrey D. Sachs of The Earth Institute that appears in the most recent issue of Brookings Papers on Economic Activity published by the Brookings Institute.

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...
