Researchers have new answers as to why some HIV-infected individuals dont progress to full-blown AIDS as rapidly as other HIV-positive people.
Northwestern University scientist Steven M. Wolinsky, M.D., and colleagues found that individuals with certain rare variations, or alleles, of two immune system genes -- human leukocyte antigens A and B (HLA-A and HLA-B) -- are better equipped to stave off HIV than people with more common sets of HLA alleles.
This finding indicates that HIV has evolved to attack the most common immune system genes and that there may be differences in how people respond to infection based on their HLA proteins. Importantly, the research, which was published in the July issue of Nature Medicine, showed that HIV influences human immune response just as humans put evolutionary pressure on the virus.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
