A statistical review of the past medical files of more than 300 couples in Uganda, in which the female partner was HIV negative and the male was HIV positive, provides solid documentation of the protective effects of male circumcision in reducing the risk of infection among women. Male circumcision also reduced rates of trichomonas and bacterial vaginosis in female partners. The study is believed to be the first to demonstrate the benefits to female partners of male circumcision.
Specifically, male circumcision reduced by 30 percent the likelihood that the female partner would become infected with the virus that causes AIDS, with 299 women contracting HIV from uncircumcised partners and only 44 women becoming infected by circumcised men. Similar reductions in risk were observed for the other two kinds of infection, but not for other common STDs, including human papillomavirus, syphilis, gonorrhea and Chlamydia.
According to the Hopkins researchers who led the study, Ronald Gray, M.D., and Steven Reynolds, M.D., M.P.H., the findings support efforts to assess male circumcision as an effective means of preventing HIV infection. Circumcision is a practice common in North America and among Jews and Muslims, but not generally in Eastern and Southern Africa, Europe or Asia.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
