Electrical signals from nerves in the brain cause weak magnetic fields which can be measured by means of magnetoencephalography (MEG). A project supported by the Austrian Science Fund (FWF) has investigated the extent to which direct measurement of neural electrical activity can be coupled with MEG to diagnose and treat epilepsy. The findings are important in view of today’s spiralling health care costs, as the apparatus used to detect magnetic fields in the brain is 30 times as expensive as that used to measure electrical signals directly.
About three percent of all Europeans develop epilepsy in the course of their lifetimes. In Austria 64,000 people are currently suffering from the disease. The illness is typically caused by unusual activity in the nerve cells in certain regions of the brain. This can be measured by electroencephalography (EEG) - a technique that has been around for over 70 years - or MEG which is a much more recent development. Professor Christoph Baumgartner of the Neurological University Clinic at Vienna General Hospital has looked into the effect of combining both methods on the accuracy with which the affected parts of the brain can be localised. The results of the research, which was supported by the FWF, indicate that the new approach is better than either EEG or MEG alone at localising the hyperactive regions of the brain. It also has the advantage that the risky "invasive" methods - introducing electrodes into the brain - do not have to be used as often.

Optical quantum computers can revolutionize computer technology. A team of researchers led by scientists from Münster University and KIT now succeeded in putting a quantum optical experimental set-up onto a chip. In doing so, they have met one of the requirements for making it possible to use photonic circuits for optical quantum computers.
Optical quantum computers are what people are pinning their hopes on for tomorrow’s computer technology – whether for tap-proof data encryption, ultrafast...
The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.
“Augmented-reality” and “wearables” have become terms we encounter almost daily. Both can make daily life a little simpler and provide valuable assistance for...
With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. They report on their findings in the scientific journal Physical Review Letters.
