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.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
