Researchers at Yale and Syracuse Universities found the first direct evidence for a mutation in mitochondrial DNA that directly affects blood pressure and cholesterol levels.
It has long been known that several metabolic traits including high cholesterol and hypertension cluster in individuals more frequently than by chance, but the underlying causes were unknown. This study, published early in Science Express on line, suggests that altered mitochondria may account for the clustering as well as the disorders. "Looking further, this finding raises the possibility that all features of the metabolic syndrome may be attributable to altered mitochondrial function," said Richard T. Lifton, Sterling Professor and Chair of Genetics at Yale and research team leader.
Metabolic syndrome is an emerging problem in industrial societies and. epidemic in the United States. The symptoms include high blood pressure, cholesterol and triglycerides, insulin resistance, obesity, and low HDL. There is independent evidence that altered mitochondrial function plays a role in insulin resistance and high triglyceride level, and the current finding indicates that these other components of metabolic syndrome may also linked to mitochondrial disfunction.

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...
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...
