Patients who suffer from multiple sclerosis (MS) typically present with centers of inflammation in the brain and spinal cord, which cause symptoms that range in severity depending on site and size. For example, sufferers feel a tingling sensation in their extremities, they stumble more or they have difficulties seeing. In extreme cases, they become incapable of moving around on their own and are confined to a wheelchair.
However, there is one finding that is the same in principle for everyone: multiple sclerosis is an autoimmune disease where one particular type of brain cell, known as an oligodendrocyte, is destroyed by the immune system. Oligodendrocytes form an insulating layer around the extensions of nerve cells that is required for efficient impulse conduction. If this conduction is disturbed as a consequence of damage to the insulating layer, the nerves cannot transfer relevant “messages” as effectively as before.

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
