| Researchers realize high-power, narrowband terahertz source at room temperature Posted: 30 Sep 2011 09:30 AM PDT Researchers have developed a simpler way to generate single-chip terahertz radiation, a discovery that could soon allow for more rapid security screening, border protection, high sensitivity biological/chemical analysis, agricultural inspection, and astronomical applications.  |
| High-performance simulation, neutrons uncover three classes of protein motion Posted: 30 Sep 2011 06:35 AM PDT Molecular motion in proteins comes in three distinct classes, according to researchers. The research team combined high-performance computer simulation with neutron scattering experiments to understand atomic-level motions that underpin the operations of proteins.  |
| Cosmic weight watching reveals black hole-galaxy history Posted: 30 Sep 2011 04:17 AM PDT Using state-of-the-art technology and sophisticated data analysis tools, a team of astronomers has developed a new and powerful technique to directly determine the mass of an active galaxy at a distance of nearly 9 billion light-years from Earth. This pioneering method promises a new approach for studying the co-evolution of galaxies and their central black holes. First results indicate that for galaxies, the best part of cosmic history was not a time of sweeping changes.  |
| Astronomers reveal supernova factory Posted: 30 Sep 2011 04:17 AM PDT A team of astronomers has detected seven previously unknown supernovae in a galaxy 250 million light years away. Never before have so many supernovae been discovered at the same time in the same galaxy.  |
| Engineers 'cook' promising new heat-harvesting nanomaterials in microwave oven Posted: 29 Sep 2011 09:28 AM PDT Waste heat is a byproduct of nearly all electrical devices and industrial processes, from driving a car to flying an aircraft or operating a power plant. Engineering researchers have developed new nanomaterials that could lead to techniques for better capturing and putting this waste heat to work. The key ingredients for making marble-sized pellets of the new material are aluminum and a common, everyday microwave oven.  |
| Posted: 29 Sep 2011 07:30 AM PDT Hubble's famous images of galaxies typically show elegant spirals or soft-edged ellipses. But these neat forms are only representative of large galaxies. Smaller galaxies like the dwarf irregular galaxy Holmberg II come in many shapes and types that are harder to classify. This galaxy's indistinct shape is punctuated by huge glowing bubbles of gas.  |
