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.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
