Findings reported in this weeks New England Journal of Medicine (November 3 issue) highlight promising findings from two Seattle-based researchers on the origins of bacterial vaginosis (BV).
In a collaborative effort to identify specific bacterial markers for bacterial vaginosis in vaginal-fluid samples, David Fredricks, MD, of the Program in Infectious Diseases, Fred Hutchinson Cancer Research Center and Jeanne Marrazzo, MD, MPH, of the University of Washington and Harborview Medical Center in Seattle report the detection of three newly recognized bacteria that were highly specific for bacterial vaginosis. Subjects for this study were recruited from Dr. Marrazzos Vaginal Health Project and from Public Health-Seattle and King County Sexually Transmitted Disease (STD) Clinic. Although preliminary, the researchers are hopeful that these findings may contribute to identifying the specific cause of and better treatment for the disease.
Bacterial vaginosis is the most common cause of vaginitis, and the most common reason women seek treatment for vaginal symptoms. The cause of BV is not known. In recent years, awareness of the adverse effects of BV has grown markedly. Among pregnant women, BV may cause up to 10% of low-birth weight deliveries, and in several studies has been strongly implicated in increasing womens risks of becoming infected with other STD and with HIV. While it may cause abnormal discharge, odor, and itching, BV often exists without causing any symptoms, and women may not know they have it. BV can be treated with antibiotics but often comes back. For unknown reasons, lesbians and bisexual women apparently have a higher occurrence of BV than heterosexual women.

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.

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.
