With an aging population, and with people living longer, experts say bone fractures will become a bigger and more costly problem unless more is done to prevent them. Osteoporosis (reduced bone mineral density) is most common in older adults, particularly women. It is a major risk factor for bone fractures, which can cause significant suffering while carrying high economic costs. While vitamin D has been shown to reduce the risk of fracture in the elderly, a study recently published in the Journal of the American Medical Association (JAMA) raises the question of how much vitamin D is enough.
The Recommended Dietary Allowance (RDA) of vitamin D for older adults is between 400 and 600 International Units (IU) per day. In their review of the existing literature, a team of scientists including senior author Bess Dawson-Hughes, MD, director of the Bone Metabolism Laboratory at the Jean Mayer USDA Human Nutrition and Research Center on Aging at Tufts University, found that this dose was not effective in reducing nonvertebral fracture rates among study participants. The researchers concluded, though, that higher daily doses, in the range of 700 to 800 IU, may reduce the risk of fracture by approximately 25 percent.

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.
Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...
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...
