Exercise is an important part of staying healthy and reducing the societal cost of health care. We tend to stop exercising when our bodies signal that we are tired or fatigued. Previously, it was thought that fatigue happened when our energy store became depleted or when the waste products from producing energy accumulated in our muscles causing cramp.
However, research on patients suffering from chronic fatigue syndrome or “Yuppie Flu” has shown that fatigue occurs even though their ability to contract their muscles is the same as in a normal individual. This has led to the theory that the brain plays a central, controlling role in fatigue.
In an effort to understand this role, Prof. Christopher Vaughan from the University of Cape Town, South Africa will join forces with Prof. Mark O’Malley, Dept. of Electronic Engineering and Conway Institute of Biomolecular and Biomedical Research, University College Dublin and Dr. Sean Connolly, a clinical neurologist in St. Vincent’s University Hospital.

Spectrally narrow x-ray pulses may be “sharpened” by purely mechanical means. This sounds surprisingly, but a team of theoretical and experimental physicists developed and realized such a method. It is based on fast motions, precisely synchronized with the pulses, of a target interacting with the x-ray light. Thereby, photons are redistributed within the x-ray pulse to the desired spectral region.
A team of theoretical physicists from the MPI for Nuclear Physics (MPIK) in Heidelberg has developed a novel method to intensify the spectrally broad x-ray...
Physicists working with researcher Oriol Romero-Isart devised a new simple scheme to theoretically generate arbitrarily short and focused electromagnetic fields. This new tool could be used for precise sensing and in microscopy.
Microwaves, heat radiation, light and X-radiation are examples for electromagnetic waves. Many applications require to focus the electromagnetic fields to...
Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
