The first study, in Proceedings of the National Academy of Sciences, concerns the intimate signaling between the ribosome and an elongation factor (EF-Tu) that is essential to the successful assembly ...
Studies and Analyses |The study, which was led by Dr. Chen, is reported in Issue 52 of Science in China (G) because of its significant research value.Many explosive phenomena on the Sun, such as solar flares, invol...
Physics and Astronomy |An upgrade to a Cray XT5 high-performance computing system deployed by the Department of Energy has made the “Jaguar” supercomputer the world’s fastest. Located at Oak Ridge National Laboratory, Jagua...
Physics and Astronomy |"Climate change is making itself felt in terms of day-to-day weather in the United States," says NCAR scientist Gerald Meehl, the lead author. "The ways these records are being broken s...
Earth Sciences |The ratio of record highs to lows is likely to increase dramatically in coming decades if emissions of greenhouse gases continue to climb."Climate change is making itself felt in terms of...
Earth Sciences |The method overcomes a longstanding timing gap in modeling nanometer-scale materials and many other physical, chemical and biological systems at atomic and molecular levels.The new mathematica...
Physics and Astronomy |Physicists at Harvard University have created a quantum gas microscope that can be used to observe single atoms at temperatures so low the particles follow the rules of quantum mechanics, behaving in ...
Physics and Astronomy |Thirty years ago, theorists John Dawson and Toshiki Tajima proposed an idea for making them thousands of times smaller: surf the particles on plasma waves driven by short intense laser pulses. Since p...
Physics and Astronomy |Suggesting that atoms in a solid can move or be transported through it seems as impossible as using a syringe to inject material into a billiard ball. It shouldn’t work. But it turns out to be possibl...
Physics and Astronomy |For years scientists have struggled with the difficult physics of inertial confinement fusion. This is the attempt to compress a target capsule containing isotopes of hydrogen with high-powered lasers...
Physics and Astronomy |After finishing the IRRIIS research project, the Fraunhofer IAIS can present new results to reduce the susceptance to failure of critical infrastructures (telecommunication, energy- and water supply)....
Information Technology |"Nature is full of surprises, and IBEX has been lucky to discover one of those surprises," said Priscilla Frisch, a senior scientist in astronomy & astrophysics at the University of Chicago....
Physics and Astronomy |This is the conclusion which scientists of an international consortium coordinated by IOW draw after a four-year project period. In the framework of two complementary projects (QuantAS-Off funded by t...
Ecology, The Environment and Conservation |The results of the experiment at the Department of Energy’s Oak Ridge National Laboratory and at the National Center for Atmospheric Research are published in the current issue of Biogeosciences. They...
Earth Sciences |Using computer modeling, the Translational Genomics Research Institute and Scottsdale Healthcare have discovered lung cancer 'pathways' that could become targets for new drugs, according to ...
