The epidemic of HIV/AIDS in India is following the same pattern as that of sub-Saharan Africa in the 1980s, and it could become just as devastating unless preventive action is taken now, according to researchers from the University of California, Berkeley, in a paper to be published Saturday (June 21) in the British Medical Journal.
"In hindsight, opportunities were missed to stem the explosive growth of AIDS in Africa," says Dr. Malcolm Potts, professor of population and family planning at UC Berkeleys School of Public Health and lead author of the paper. "It would be a tragedy if we dont apply the lessons learned from the failure to control the spread of HIV in Africa to the current situation in India. It is very painful to watch history repeating itself."
According to the Joint United Nations Programme on HIV/AIDS, 20 percent of people over 15 in some sub-Saharan African countries are HIV-positive, and 70 percent of them will eventually die from AIDS.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
