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."

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
