Caltech researchers develop amplifier with niobium titanium nitride for exploring the cosmos and the quantum world Posted: 13 Jul 2012 05:50 PM PDT Researchers at the California Institute of Technology (Caltech) and NASA's Jet Propulsion Laboratory (JPL) have developed a new type of amplifier for boosting electrical signals. The device can be used for everything from studying stars, galaxies, and black holes to exploring the quantum world and developing quantum computers. "This amplifier will redefine what it is possible to measure," says Jonas Zmuidzinas, Caltech's Merle Kingsley Professor of Physics, the chief technologist at JPL, and a member of the research team. read more

How cells degrade aberrant membrane proteins Posted: 13 Jul 2012 03:54 PM PDT Researchers from Heidelberg University’s Center for Molecular Biology (ZMBH) have achieved unexpected insights into the process of how damaged proteins are degraded within cells. Their work focused on the function of a special protease. This enzyme can hydrolyse peptide bonds in the plane of cellular membranes, a site where such water-requiring reactions commonly do not occur. The scientists working with Dr. Marius Lemberg could now show that this unusual protease recognises and degrades aberrant proteins directly in the membrane. read more
