Experiments in female monkeys have for the first time shown that when used in combination, vaginal gels known as microbicides can protect against an HIV-like virus. The research, funded largely by the National Institute of Allergy and Infectious Diseases (NIAID), one of the National Institutes of Health (NIH), suggests that similar combination microbicides could potentially provide a safe, effective and practical way to prevent HIV transmission to women, according to study investigators.
The study, published online October 30 in the journal Nature, represents the first successful testing of combination microbicides in a primate model.
Women make up nearly half of all people living with HIV worldwide, and a vast majority of new cases of HIV infection in women result from heterosexual intercourse. "This study demonstrates that combination microbicides are feasible," says NIAID Director Anthony S. Fauci, M.D. "We need to build on these promising animal studies and move toward establishing the safety and effectiveness of combination microbicides in women."

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
