Scientists at the University of Sussex have produced synthetic ‘cosmic dust’ to help space researchers understand information gathered by a mission to Saturn.
CASSINI, an unmanned probe launched by NASA in October 1997, is due to go into orbit around Saturn this summer. One of the aims of the CASSINI mission is to study the planet’s famous rings. It is already recognised Saturn’s rings are made of cosmic dust, but very little is known about the composition of the dust.
Cosmic dust moves at speeds of up to 70,000 mph. When dust from Saturn’s rings hits CASSINI’s onboard detector, it will be obliterated in the collision. CASSINI will record data generated from dust impacts for transmission back to Earth.

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...
