Young stars ejecting plasma could give us clues into the Sun’s past Kyoto, Japan — Down here on Earth we don’t usually notice, but the Sun is frequently ejecting huge masses of plasma into space. These are called coronal mass ejections (CMEs). They often occur together with sudden brightenings called flares, and sometimes extend far enough to disturb Earth’s magnetosphere, generating space weather phenomena including auroras or geomagnetic storms, and even damaging power grids on occasion. Scientists believe that when…
Shar-Pei Autoinflammatory Disease (SPAID) is a complex inflammatory disease. Typical signs are recurrent bouts of fever, inflammations of the ear, arthritis and a reddened skin. The dogs can also develop amyloidosis. Scientists at the University of Veterinary Medicine Hannover developed a genetic test for SPAID predisposition.

Oncolytic virotherapy for cancer has emerged as a novel and promising therapeutic approach to replace standard cancer therapies, which often provide limited efficacy at the cost of unpleasant or severe side effects. Here, a novel VSV/NDV hybrid virus was engineered that combines the advantages of both vesicular stomatitis virus (VSV) and Newcastle disease virus (NDV) vectors, while the safety concerns of both are eliminated.
Scientists of the MEET at Wilhelms University of Muenster developed a set of alkylsilyl complexes (MOSi) as elecrolyte additive, which enhance the performance of lithium ion batteries. Previous studies have shown that electrolyte additives based on metals and semimetals (LiBOB, Mg(TFSI)2, Al(TFSI)3) as well as additives containing trimethylsiloxyl (TMS) groups as ligands can have positive impact on the cycling performance of lithium ion battery cells due to solid electrolyte interphase (SEI) and/or cathode electrolyte interphase (CEI) film forming properties and/or scavenging properties towards acidic impurities. The results of LIB full-cells show a twofold cycle life compared to the standard electrolyte. The addition of the M(TMS)x based additives lowers the charge transfer impedance during prolonged cycling. MOSi leads to lithium ion batteries with enhanced anti fading performance.
A German patent application is pending. International applications are possible.

Skyrmions are stable topological vortices in the magnetization. They can be created on surfaces of magnetic materials where they move through the materiallike a kind of hose. Their motion can be controlled with magnetic and/or electric fields or currents. Skyrmions have a diameter in the nm range and can be easily generated and also detected. SkyrMem is a novel storage arrangement that uses these properties of the skyrmions. It consists of a strip of magnetic material, about twice as wide as the diameter of a skyrmion. A potential barrier is applied in the center of the strip so that the skyrmions can only be placed above or below the line. This can be used to represent logical “1” and “0”. By applying a voltage, the scyrmions can be moved along the strip, permitting serial reading of the information.
With SkyrMem, a completely new type of digital memory can be realized. Since scyrmions are very small and nevertheless stable, storage densities above the values customary today for hard disks are possible. High readout rates can also be achieved. SkyrMem provides a technical basis for the storage media of the future.
A German patent application was filed, international applications are still possible.
