Iowa City Veterans Affairs (VA) Medical Center and University of Iowa (UI) researchers have unlocked part of the mystery of how a harmless virus known as GBV-C slows the progression of HIV and prolongs survival for many patients. The report appears in the June 19 issue of The Lancet, the leading British medical journal.
The findings provide the clearest insight yet into the biological mechanisms of GBV-C, a benign cousin of the hepatitis C virus. The virus infects almost all HIV patients at some point in their illness, but seems to cause no harm by itself. When present over several years, the virus appears to slow HIV growth and keep patients from developing full-blown AIDS.
A study by the Iowa City team and other collaborators published in the March 4, 2004, New England Journal of Medicine found that 75 percent of men with persistent GBV-C infection survived at least 11 years after their HIV diagnosis, versus only 16 percent of men who were initially co-infected with GBV-C but cleared the virus over time. The men had been studied before the advent of effective HIV medications.

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.
We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...

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...
