Information on the internet about the health risks associated with the consumption of smokeless tobacco usually overstates the risk. This is the conclusion of research published today in the Open Access journal BMC Public Health, entitled "You might as well smoke; the misleading and harmful public message about smokeless tobacco". A study of 316 internet websites showed that most government, health advice, and advocacy websites suggested that smokeless tobacco use is as harmful as cigarette smoking, even though the risk is actually extremely small compared to that from smoking.
Carl V. Phillips, of the University of Texas School of Medicine Center for Clinical Research and Evidence Based Medicine and School of Public Health, and colleagues report that the public is unlikely to find accurate information on the comparative risks of smokeless tobacco and cigarettes, leading to misconceptions amongst consumers. Phillips notes, "smokers can dramatically cut their risks by switching to smokeless tobacco, a strategy called harm reduction, but they have little chance of learning this. Similarly, authoritative organizations are telling smokeless tobacco users, in effect, you might as well smoke, a public health message that actually encourages people to switch to a much more dangerous product."
Phillips and colleagues conducted a systematic review of popular sources of information available on the internet, by looking at the content of websites that provide information about smokeless tobacco and health, found using a Google search. They found that of the 316 sites that were suitable for inclusion in the review, "almost every website had statements that played up the health risks from smokeless tobacco without caveat". Furthermore, "a large portion of websites directly stated or implied that the risks from smokeless tobacco and cigarettes are similar". The websites of organisations including the U.S. National Cancer Institute and other government agencies, the American Cancer Society, and several of the most popular health advice sites contained information that either explicitly or implicitly suggested that the risks of smokeless tobacco and cigarettes are comparable.

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.
