Study shows river water, sewer lines are possible sources
Viruses from human sources occur in the La Crosse, Wisconsin municipal drinking water supply prior to its chlorination, according to a study published today in the scientific journal Applied and Environmental Microbiology. Although the city’s treated water meets or exceeds state and federal standards for drinking water, researchers and public health officials agree that more study is needed to pinpoint sources of the viruses and to determine if some viruses are surviving chlorination and making people sick with diarrhea and vomiting.
The objective of the study, by Marshfield Clinic Research Foundation (MCRF) and the U.S. Geological Survey (USGS), was to determine whether the amount of Mississippi River water moving through the riverbank and infiltrating city wells was related to the frequency of virus detection in the wells.

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...
