While scientists work to find the perfect solution to preventing the spread of HIV/AIDS, a reasonable option--the female condom--is not being promoted, especially in African and southeast Asian countries where the deadly virus is most prevalent, according to a new study. "While were waiting for perfection, people are dying," said Dr. Amy Kaler, a sociology professor at the University of Alberta.
In a paper published in the November/December issue of Culture, Health & Sexuality, Kaler presents findings that show female condoms are being dismissed as a viable method of protection for a number of reasons, including cost and availability in developing nations, and, in North America, for esthetic reasons.
These attitudes have serious implications for developing the next generation of barrier methods, such as revamped diaphragms and cervical caps to reduce transmission of AIDS. "Female condoms, and female barrier methods in general, are a very important avenue of exploration for HIV protection that has been prematurely closed off," Kaler said.

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
Cardiovascular tissue engineering aims to treat heart disease with prostheses that grow and regenerate. Now, researchers from the University of Zurich, the Technical University Eindhoven and the Charité Berlin have successfully implanted regenerative heart valves, designed with the aid of computer simulations, into sheep for the first time.
Producing living tissue or organs based on human cells is one of the main research fields in regenerative medicine. Tissue engineering, which involves growing...
A team of scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg investigated optically-induced superconductivity in the alkali-doped fulleride K3C60under high external pressures. This study allowed, on one hand, to uniquely assess the nature of the transient state as a superconducting phase. In addition, it unveiled the possibility to induce superconductivity in K3C60 at temperatures far above the -170 degrees Celsius hypothesized previously, and rather all the way to room temperature. The paper by Cantaluppi et al has been published in Nature Physics.
Unlike ordinary metals, superconductors have the unique capability of transporting electrical currents without any loss. Nowadays, their technological...
