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.

Solar cells based on perovskite compounds could soon make electricity generation from sunlight even more efficient and cheaper. The laboratory efficiency of these perovskite solar cells already exceeds that of the well-known silicon solar cells. An international team led by Stefan Weber from the Max Planck Institute for Polymer Research (MPI-P) in Mainz has found microscopic structures in perovskite crystals that can guide the charge transport in the solar cell. Clever alignment of these "electron highways" could make perovskite solar cells even more powerful.
Solar cells convert sunlight into electricity. During this process, the electrons of the material inside the cell absorb the energy of the light....
Empa researchers have succeeded in applying aerogels to microelectronics: Aerogels based on cellulose nanofibers can effectively shield electromagnetic radiation over a wide frequency range – and they are unrivalled in terms of weight.
Electric motors and electronic devices generate electromagnetic fields that sometimes have to be shielded in order not to affect neighboring electronic...

With an X-ray experiment at the European Synchrotron ESRF in Grenoble (France), Empa researchers were able to demonstrate how well their real-time acoustic monitoring of laser weld seams works. With almost 90 percent reliability, they detected the formation of unwanted pores that impair the quality of weld seams. Thanks to a special evaluation method based on artificial intelligence (AI), the detection process is completed in just 70 milliseconds.
Laser welding is a process suitable for joining metals and thermoplastics. It has become particularly well established in highly automated production, for...
