Physically active have reduced risk of prostate cancer

28.10.2009
Lifetime physically active men have a lower risk of developing prostate cancer, according to a new study from the Swedish medical university Karolinska Institutet (KI). The effect was observable in those who had been sitting for less than half their working day or had been physically active for more than an hour a day.

In 1997, over 45,000 Swedish men between the ages of 45 and 79 responded to a survey on lifestyles and degree of lifetime physical activity. Ten years on, the researchers have now followed up the group with respect to the incidence of prostate cancer.

The results from this prospective cohort study, which are published in British Journal of Cancer, show that a high level of physical activity correlates with a lower risk of developing prostate cancer.

Men who reported that they had been spending less than half their working day sitting had a 20 per cent lower risk of prostate cancer than those who had been sitting for most of the time. Men who walked or cycled on average more than 60 minutes a day had a 14 per cent lower risk than those who walked or cycled 20 to 40 minutes a day.

According to the researchers, this is the first time that a link has been observed between long-term physical activity and the risk of prostate cancer. However, the biological mechanism through which physical activity can affect this risk remains unknown.

Im Focus: A Challenging European Research Project to Develop New Tiny Microscopes

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...

Im Focus: Giant Magnetic Fields in the Universe

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...

Im Focus: Tracing down linear ubiquitination

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...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

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.
