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.

Augsburg chemists and physicists report how they have succeeded in the extremely difficult separation of hydrogen and deuterium in a gas mixture.
Thanks to the Surface Acoustic Wave (SAW) technology developed here and already widely used, the University of Augsburg is internationally recognized as the...
Adjusting the thermal conductivity of materials is one of the challenges nanoscience is currently facing. Together with colleagues from the Netherlands and Spain, researchers from the University of Basel have shown that the atomic vibrations that determine heat generation in nanowires can be controlled through the arrangement of atoms alone. The scientists will publish the results shortly in the journal Nano Letters.
In the electronics and computer industry, components are becoming ever smaller and more powerful. However, there are problems with the heat generation. It is...
Scientists have visualised the electronic structure in a microelectronic device for the first time, opening up opportunities for finely-tuned high performance electronic devices.

Scientists at the University Würzburg and University Hospital of Würzburg found that megakaryocytes act as “bouncers” and thus modulate bone marrow niche properties and cell migration dynamics. The study was published in July in the Journal “Haematologica”.
Hematopoiesis is the process of forming blood cells, which occurs predominantly in the bone marrow. The bone marrow produces all types of blood cells: red...
For some phenomena in quantum many-body physics several competing theories exist. But which of them describes a quantum phenomenon best? A team of researchers from the Technical University of Munich (TUM) and Harvard University in the United States has now successfully deployed artificial neural networks for image analysis of quantum systems.
Is that a dog or a cat? Such a classification is a prime example of machine learning: artificial neural networks can be trained to analyze images by looking...
