A new study published in BMC Public Health shows that breathing in second-hand smoke significantly increases the risk of developing heart problems in non-smokers. These findings have serious consequences for public health giving weight to calls for smoking to be banned in public places.
In 1995 cardiovascular diseases accounted for nearly 15 million deaths, approximately 30% of deaths worldwide. Smokers are becoming increasingly aware of the links between smoking and heart disease as warnings such as "smoking causes heart disease" are emblazoned across cigarette packaging across the world. The effects of second hand smoke or passive smoking is less clear because it is difficult to measure the exposure of non-smokers to cigarette smoke. Researchers at the University of Athens in Greece have carried out an extensive survey of approximately 2000 non-smoking patients. The patients were volunteers from two different groups, the first contained patients who had attended hospital suffering from a heart attack or acute angina that was not a result of a pre-existing condition. The second control group consisted of patients being treated as outpatients for routine examinations or minor surgical procedures who had no history of cardiovascular problems.
Both groups completed a questionnaire, which asked a variety of questions to identify factors that may put them at risk of developing heart problems. These factors included age, hypertension, high cholesterol, diabetes, a family history of heart disease, physical inactivity, obesity, poor education, depression and low income.

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.
