Due to the 2005 Nobel Prize in physiology and medicine received by Robin Warren and Barry Marshall, the name of the Helicobacter pylori bacterium is now a buzz word. According to contemporary overview, the bacterium gets into the stomach with food and water. In adverse conditions (stress, malnutrition, genetic factors, etc.), the bacterium invades the wall of the stomach or the duodenum under the mucous membrane and produces toxins destroying the walls. This is how gastritis originates, turning into ulcer.
It is fair to say that the Helicobacter pylori bacterium does not cause gastritis and ulcer with all their hosts. There will always be some percentage of people resistant to some bacterium or virus. But if gastritis or ulcer symptoms are clear, then it is sufficient to determine the Helicobacter pylori presence to start treatment (which is by the way well-developed).
Previously, to diagnose the disease, patients had to endure an extremely unpleasant procedure (gastroscopy) –swallowing a stomach pump. The procedure is not only unpleasant, but also dangerous: it traumatizes the larynx and esophagus. Besides, a stomach pump can bring some infection in the patient’s organism if it has not been properly sterilized.

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...
