Researchers at Stanford University Medical Center have devised a way to sneak DNA into skin cells taken from people with a potentially deadly genetic skin disorder. These modified cells later formed normal, healthy skin when transplanted onto the skin of mice. The technique, published in the advance online publication of the October issue of the journal Nature Medicine, marks the first time researchers have stably replaced the mutated gene in this disease and introduces a new gene therapy technique that could be useful in a wide range of diseases.
"Were very hopeful," said study leader Paul Khavari, PhD, associate professor of dermatology at Stanford. "This study was performed in mice but it targets grafted human disease tissue."
The technique has advantages that could one day help it treat a variety of diseases. Not only can it accommodate large genes such as those responsible for Duchenes muscular dystrophy and cystic fibrosis, but it causes the gene to integrate into human chromosomes in locations where it will continue to make protein as long as the cell is alive. In other techniques, the inserted DNA does not become part of the chromosome and eventually breaks down or else integrates in positions where the gene gets turned off.

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...
