A report in the open access journal BMC Psychiatry presents a new hypothesis that may explain the causes of the psychiatric disease, schizophrenia. The hypothesis hinges on glia, a special type of cell, which is important for the maintenance of the connections between brain cells. By re-examining previously published research the authors suggest that schizophrenia may be caused by a combination of defective genes, which result in deficiencies of a variety of growth factors in glia, and infection by viruses, which may further weaken the glia. They conclude that this "weakening" of glia may result in the breakdown of connections between different brain cells leading to the development of schizophrenia.
Schizophrenia is a severe disabling psychiatric disease, which affects approximately 1 percent of the population. People with schizophrenia often suffer terrifying symptoms such as hearing internal voices, feelings of extreme paranoia and an inability to distinguish reality from fantasy. It is clear that schizophrenia has a strong genetic component, however analysis of individual genes alone will not give us a full understanding the causes of schizophrenia.

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.
According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
