The world´s first human test of a vaccine against the prevalent subtype of HIV in sub-Saharan African and Asia, where millions have the virus that causes AIDS, is now under way. The clinical trial uses novel technology pioneered by scientists at the University of North Carolina at Chapel Hill School of Medicine and the U. S. Army Medical Research Institute of Infectious Diseases.
The phase I trial began July 17 at Johns Hopkins University. An adult male, at low risk for HIV infection, was the first of 48 volunteers in the United States to be vaccinated.
Other U.S. sites include Columbia University, Vanderbilt University and the University of Rochester. Sites in South Africa are at the University of Witwatersrand, the Chris Hani Baragwanath Hospital in Soweto and the Medical Research Council in Durban. The two-year trial will involve 48 non-HIV-infected participants in each country at four different dose levels, using a double-blind, placebo-controlled design. The primary endpoint is safety, that the vaccine does not produce significant side effects. Researchers also will look at the vaccine´s ability to induce an immune response.

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...
