Record-high magnetic fields in the lab, almost a Gigagauss in magnitude, have been achieved by aiming intense laser light at a dense plasma, expanding the possibilities for laboratory re-creations of astrophysical events.
At last weeks APS Division of Plasma Physics Meeting in Orlando, researchers from Imperial College, London, and the Rutherford Appleton Lab in the UK announced evidence of super-strong magnetic fields that are hundreds of times more intense than any previous magnetic field created in an Earth laboratory and up to a billion times stronger than our planets natural magnetic field. Such intense magnetic fields may soon enable researchers to recreate extreme astrophysical conditions, such as the atmospheres of neutron stars and white dwarfs, in their very own laboratories.
At the Rutherford Appleton Laboratory near Oxford in the UK, researchers at the VULCAN facility aimed intense laser pulses, lasting only picoseconds (trillionths of a second), at a dense plasma. The resulting magnetic fields in the plasma were on the order of 400 Megagauss.

Cells need to repair damaged DNA in our genes to prevent the development of cancer and other diseases. Our cells therefore activate and send “repair-proteins”...
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...
