AIDS researchers have developed a candidate vaccine strategy that, for the first time, demonstrates an ability to elicit antibodies that block the infection of multiple HIV virus strains -- an elusive scientific goal that has been pursued for a decade.
The candidate vaccine - still early in developmental stages at the Institute of Human Virology (IHV) -- is described in a report to appear during the week of Aug. 19-23 in the U.S. Proceedings in the National Academy of Sciences (PNAS). It is authored by Drs. Timothy Fouts, Anthony Devico, and colleagues at the IHV, a center of the University of Maryland Biotechnology Institute and affiliated with the University of Maryland Medical Center, and Dr. Ranajit Pal and colleagues at Advanced BioScience Laboratories, Inc. (ABL) in Kensington, Md.
One of the major challenges in developing an effective AIDS vaccine has long been the fact that the virus that causes AIDS, much like the influenza virus, exists as multiple strains that present many different faces to the immune system, say the authors. The surface of the AIDS virus, HIV, is coated with a protein called gp120 that has chemical features that vary from strain to strain. It has been difficult for researchers to find a single vaccine component that is able to generate antibodies that recognize the many forms of gp120 that exist in nature.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
