Incidence of ovarian cancer varies in Europe due to changing risk factors and improved treatment
Europe has one of the highest incidence rates of ovarian cancer in the world, making it an important public health issue. A new large-scale study of ovarian cancer trends found that while it is declining in most northern European countries, it is increasing in a few southern and eastern European countries. The study is published October 25, 2004 in the online edition of the International Journal of Cancer – the official journal of the International Union Against Cancer (UICC) – and is available online via Wiley InterScience.
Ovarian cancer rates may be affected by several factors. Hormonal factors include a womans age when menstruation began, the number of menstrual cycles she has had, and reaching menopause at a late age, In addition, nulliparity (never having children) or a low parity (e.g. having only borne children 1-2 times) has also been associated with increased risk of this type of cancer, while use of oral contraceptives has been associated with a decreased risk. Other factors include heredity, with ovarian cancer tending to run in families, and diet, although this relationship remains uncertain.

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“.

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.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
