Marine researchers and scientists have long sought a practical way to track the position and migration of fish in the world’s oceans in order to provide research data for stock management and fish conservation.
Sigmur Gudbjornsson, Managing Director of Stjornu-Oddi, the Icelandic lead partner in EUREKA project E! 2326 GPSFISH, describes how they solved the problem by having ships “transmit by sonar GPS (global positioning satellite) data which is then stored on any fish that has been previously tagged within a 5 km range.”
As tagged cod, plaice or salmon swim, other sonar pings are recorded from vessels equipped with sonar developed by the Norwegian project partner, Simrad. The tag stores the sonar’s position at the time and date it was pinged. This turns the tagged fish into an important research instrument, gathering vital information on the species.

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...
