While patients hospitalized for a heart attack have long been treated with morphine to relieve chest pain, an analysis by researchers from the Duke Clinical Research Institute has shown that these patients have almost a 50 percent higher risk of dying.
The researchers call for a randomized clinical trial to confirm their analysis. Meanwhile, they advise cardiologists to begin treatment with sufficient doses of nitroglycerin to relieve pain before resorting to morphine. In their analysis of the clinical data and outcomes of more than 57,000 high-risk heart attack patients -- 29.8 percent of whom received morphine within the first 24 hours of hospitalization -- the researchers found that those who received morphine had a 6.8 percent death rate, compared to 3.8 percent for those receiving nitroglycerin. The increase in mortality persisted even after adjustment for the patients baseline clinical risk.
The results of the Duke were published as a fast-track article in the American Heart Journal.

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...
