Taking antibiotics weekly for a year does not reduce the risk of a heart attack or other cardiac event for patients with stable coronary artery disease, according to a University of Washington study. The study was published in the April 22 edition of the New England Journal of Medicine.
Previous studies have found the bacteria Chlamydia pneumoniae in the arterial plaque of patients with coronary artery disease. Some doctors have reasoned that removal of C. pneumoniae from the system could reduce the risk of subsequent cardiac events. Prescription of antibiotics for this purpose had not been tested through a randomized clinical trial. The investigation of whether antibiotics could be used to treat the bacteria, and therefore reduce the risk of cardiac events, was conducted at 27 different sites in the United States.
All U.S. adults have been exposed to C. pneumoniae, which spreads through the air and causes pneumonia or mild repiratory disease, at some point in their lives.

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...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
