A team of three scientists and engineers from the Mullard Space Science Laboratory, UK, and the Astronomical Institute of the University of Wroclaw, Poland, are travelling to Libya to observe the total eclipse of the Sun on March 29th 2006. They will be using an instrument designed to understand why the Sun’s outer atmosphere is so hot.
The solar atmosphere or corona, which is normally only visible from the Earth at times of total solar eclipses, has a temperature of 1—2 million degrees Celsius. The corona also emits ultraviolet and X-ray radiation, which has been observed with spacecraft such as the ESA/NASA Solar and Heliospheric Observatory (SOHO). But despite more than 60 years of study, the heating mechanism of the corona remains unknown.
The instrument used by the Anglo-Polish team, the Solar Eclipse Coronal Imaging System (SECIS), consists of a double telescope on a driven mount with fast-frame electronic cameras that will form images of the corona during eclipse totality at the rate of 40 frames per second. This is far higher than can be accomplished with spacecraft instrumentation because of telemetry restrictions.

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...
