In the first study to directly compare the emergence of antibiotic resistance following topical treatment between two antibiotics routinely prescribed for a common vaginal infection, researchers from the Magee-Womens Research Institute have found antibiotic-resistant bacteria more likely to develop with the drug clindamycin than metronidazole. The study is being published in the October issue of the American Journal of Obstetrics and Gynecology.
Researchers followed 99 women between the ages of 18 and 45 who were being treated for bacterial vaginosis (BV), a common gynecological complaint that infects up to 50 percent of women in some populations. BV is characterized by an increase in vaginal alkalinity and substitution of certain beneficial bacteria, particularly those that produce hydrogen peroxide, with more toxic bacteria. Among the infections more prominent symptoms is a milky, foul-smelling discharge.
"Symptoms of discharge are one of the most common reasons women visit a gynecologist," said Sharon Hillier, Ph.D., professor in the departments of obstetrics, gynecology and reproductive sciences and molecular genetics and biochemistry at the University of Pittsburgh School of Medicine and senior author of the study. "For years, clinicians have thought of BV infection as a minor problem, but studies have shown that women who have BV are more likely to get herpes and other sexually transmitted diseases, including HIV."

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.
