Magnetic quantum objects in a ‘nano egg-box’

Magnetic quantum objects in superconductors, so-called “fluxons”, are particularly suitable for the storage and processing of data bits. Computer circuits based on fluxons could be operated with significantly higher speed and, at the same time, produce much less heat dissipation. Physicists around Wolfgang Lang at the University of Vienna and their colleagues at the Johannes-Kepler-University Linz have now succeeded in ...

New Technique Developed to Detect Epilepsy Brain Region for Surgery

Researchers have identified a unique way to detect epileptic brain tissue that causes seizures. The chemical biomarker can be detected noninvasively using a technique called magnetic resonance spectroscopy to help doctors to precisely identify small regions of abnormal brain tissue in early-stage epilepsy patients. This can help in surgery of epileptic brain regions for therapeutic removal without the need for ...
