Authors urge caution in JAMA article: High dose nutrient supplementation may have more adverse consequences than anticipated
In a special communication piece that appears in the July 20th issue of the Journal of the American Medical Association (JAMA), Alice Lichtenstein, DSc, senior scientist and director of the Cardiovascular Nutrition Laboratory at the Jean Mayer U.S. Department of Agriculture (USDA) Human Nutrition Research Center on Aging at Tufts University and the Centers director and senior scientist, Robert Russell, MD, report that the most promising data on nutrition and optimal health outcomes relate to dietary patterns, not nutrient supplements. They further state that there are insufficient data to justify altering public health policy from an emphasis on foods and dietary patterns to one on supplements.
The authors emphasize that nutrient supplementation, particularly for certain at-risk populations, has an important place in health care. However, they point out that there is an important difference between observing associations between particular nutrients and health outcomes and detecting causal connections.

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...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales

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...
