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.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
