In this study a team of researchers, led by Peggy Näsman, Karolinska Institute, Department of Dental Medicine, Stockholm, Sweden, investigated possible adverse health effects on bone tissue from drinking fluoridated water.
The study included a large cohort of Swedish residents chronically exposed to various fluoride levels, with the hypothesis of a possible association between fluoride level in the drinking water and the risk of hip fracture. With nearly half a million individuals participating in this study, this is believed to be one of the largest studies of its kind. The complete study is published in the OnlineFirst portion of the IADR/AADR Journal of Dental Research.
The cariostatic benefit from water fluoridation is indisputable, but there has been debate over the past 60 years on possible adverse effects from fluoride on human health. The study assessed the association between long-term (chronic) drinking water fluoride exposure and hip fracture (ICD-7-9: '820' and ICD-10: 'S72.0-S72.2') in Sweden using nationwide registers.
Näsman and her team of researchers found no association between chronic fluoride exposure and the risk of hip fracture. The risk estimates did not change in analyses restricted to only low trauma osteoporotic hip fractures. This research suggests that chronic fluoride exposure from drinking water does not seem to have any important effects on the risk of hip fracture, in the investigated exposure range.
"Though research continues to prove the health benefits associated with drinking fluoridated water, the potential for health risks should continue to be studied," said IADR President Helen Whelton. "It is promising to know that this cohort study, performed in Sweden, doesn't find an association between drinking fluoridated water and hip fractures."

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
