Researchers have discovered that a molecule best known for its anti-microbial properties also has the ability to activate key cells in the immune response. This newly discovered function, reported in the Nov. 1, 2002, issue of Science*, suggests the molecule, a peptide called ß-defensin 2, may be useful in the development of more effective cancer vaccines. Scientists have found that ß-defensin 2 initiates a chain of events leading to the growth and multiplication of T cells, components of the immune system that recognize and kill foreign cells that have invaded the body.
Defensins are known to be an important component of the bodys immediate response to infection. ß-defensin 2 attacks and destroys a broad range of bacteria as part of the innate immune system, the bodys first line of defense against such infections.
The new finding links ß-defensin 2 to the second arm of the immune system, adaptive immunity. The adaptive immune response combats pathogens that evade the bodys initial defense mechanisms. Unlike innate immunity, the adaptive immune system develops specifically in response to an infection, changing as needed to ward off each invader.

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.

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...
