Daily consumption of whole grains has been associated in a number of studies with reductions in risk for ischemic stroke, coronary artery disease, and type 2 diabetes. The cereal fiber found in whole grains slows digestion, producing a greater feeling of fullness and helping to prevent obesity, a major risk factor for type 2 diabetes. In a long-term study of male health professionals published in the American Journal of Clinical Nutrition, Fung et al. found that men who ate several servings of whole grains per day over a period of years had a substantially reduced risk of developing type 2 diabetes, and that some risk reduction occurred even in men who were obese.
Male health professionals, age 40-75 years without a history of diabetes or cardiovascular disease were recruited in 1986 and followed for 12 years. The 42,898 participants provided information on diet, health and lifestyle using questionnaires that were mailed to them every 2 years. The classification of "whole grains" included brown rice, dark breads, whole-grain ready-to-eat cereals, and other cereal foods. The subjects were divided into quintiles of whole grain consumption, with the lowest quintile eating 0.4 servings of whole grains per day and the highest quintile averaging 3.2 servings per day. Subjects with higher whole grain intakes tended to be leaner and more physically active, to consume less fat, and were less likely to smoke or have hypertension.
Between 1986 and 1998, 1197 cases of type 2 diabetes were diagnosed in the group. In comparison to those in the bottom quintile of whole grain intake, those in the top quintile had a 42% decreased risk for type 2 diabetes. Obese persons who were physically active and had high whole grain intakes had a 52% lower risk of diabetes than inactive obese persons in the lowest whole grain intake category. The high fiber content of the bran fraction of whole grains delays gastric emptying and slows the release of glucose into the circulation, thus reducing insulin response after meals. This process may also be responsible for lower obesity levels among high consumers of whole grains because a longer period of satiety follows meals. Magnesium, which has also been shown to improve glucose and insulin response, is present in higher amounts in whole grains than in refined grains.

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

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 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...
