UCLA AIDS Institute discovery points to new drug target
Scientists have long suspected that HIV hijacks immune cells called dendritic cells to infiltrate the immune system. Now UCLA AIDS Institute researchers have shown that blocking HIVs access to a naturally occurring molecule on dendritic cells may cut their ability to smuggle the virus into other immune cells. Published in the May edition of the Journal of Virology, the discovery may lead to new drugs to prevent sexually transmitted HIV infection.
"Dendritic cells act like sentries to alert the immune system when a foreign agent tries to infiltrate the body," said Dr. Benhur Lee, UCLA assistant professor of microbiology, immunology and molecular genetics. "They also produce a molecule called DC-SIGN that plays a critical role in the sexual transmission of HIV. We wanted to see what would happen if we blocked how DC-SIGN functions in its natural environment."

Physicists have developed a technique based on optical microscopy that can be used to create images of atoms on the nanoscale. In particular, the new method allows the imaging of quantum dots in a semiconductor chip. Together with colleagues from the University of Bochum, scientists from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute reported the findings in the journal Nature Photonics.
Microscopes allow us to see structures that are otherwise invisible to the human eye. However, conventional optical microscopes cannot be used to image...
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...
