Dutch researcher Niels Prins has discovered that elderly people with a lot of damage to the small blood vessels in the brain have a greater chance of developing dementia or depression. The damage is visible on MRI scans as white matter lesions and infarcts of the brain.
Elderly people with serious white matter abnormalities and infarcts were found to deteriorate more quickly in their cognitive functioning than peers with fewer abnormalities. In particular, the processing of information was worse in the group with more white matter lesions and infarcts. This group also had an increased risk of developing dementia and depression.
Over a period of three years, one-third of the elderly people investigated exhibited an increase in white matter lesions. These elderly people had an increased risk of developing a stroke and the cognitive functioning deteriorated more quickly. Furthermore, a serious increase in the number of abnormalities in the white matter increased the risk of dementia and depression.

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...
