Saturn propellers reflect solar system origins (July 10, 2010) -- Scientists using NASA's Cassini spacecraft at Saturn have stalked a new class of moons in the rings of Saturn that create distinctive propeller-shaped gaps in ring material. It marks the first time scientists have been able to track the orbits of individual objects in a debris disk. The research gives scientists an opportunity to time-travel back into the history of our solar system to reveal clues about disks around other stars in our universe that are too far away to observe directly. ... > full story
Better barriers can help levees withstand wave erosion (July 10, 2010) -- A new barrier design could protect reservoir levees from the erosive forces of wind-driven waves, according new research. These findings could help lower the maintenance costs for constructed ponds in the lower Mississippi Delta where levee repairs can average per foot -- and sometimes are needed just five years after a reservoir is built. ... > full story
Novel ion trap with optical fiber could link atoms and light in quantum networks (July 10, 2010) -- Physicists have demonstrated an ion trap with a built-in optical fiber that collects light emitted by single ions, allowing quantum information stored in the ions to be measured. The advance could simplify quantum computer design and serve as a step toward swapping information between matter and light in future quantum networks. ... > full story
Researchers use robot to determine how human strangers develop trust (July 10, 2010) -- What can a wide-eyed, talking robot teach us about trust? A lot, according to psychology professors who are conducting innovative research to determine how humans decide to trust strangers -- and if those decisions are accurate. ... > full story
New spin on drug delivery: Chemical engineers discover an enhanced delivery method of DNA payloads into cells (July 10, 2010) -- Chemical engineers have discovered how to "greatly enhance" the delivery of DNA payloads into cells. Lu's ultimate goal is to apply this technique to create genetically modified cells for cancer immunotherapy, stem cell therapy and tissue regeneration. ... > full story
Rain of giant gas clouds create active galactic nuclei: New research explains how galaxy centers light up (July 10, 2010) -- Galaxies like our own were built billions of years ago from a deluge of giant clouds of gas, some of which continue to rain down. Now new calculations tie the rain of giant clouds of gas to active galactic nuclei, the extremely bright centers of some galaxies. ... > full story
Scientists use computer algorithms to develop seasonal flu vaccines (July 10, 2010) -- Computer scientists have developed a rapid and effective approach to produce vaccines for new strains of influenza viruses. The researchers hope to develop the new technology and provide an efficient method to confront the threat of seasonal epidemics. ... > full story
Heavy metal rock set to take the stage (July 10, 2010) -- On its way to a 2014 rendezvous with comet 67P/Churyumov-Gerasimenko, the European Space Agency's Rosetta spacecraft, with NASA instruments aboard, will fly past asteroid Lutetia this Saturday, July 10. The instruments aboard Rosetta will record the first close-up image of a metal asteroid. They will also make measurements to help scientists derive the mass of the object, understand the properties of the asteroid's surface crust, record the solar wind in the vicinity and look for evidence of an atmosphere. ... > full story
New system helps locate car park spaces (July 10, 2010) -- Researchers in Spain have developed a system to locate unoccupied car spaces on the street and guide users to the nearest available space. The system has been named XALOC and is based on new positioning technology offering more precision in urban areas than GPS technology. ... > full story
Mathematical formula predicts clear favorite for the FIFA World Cup (July 9, 2010) -- A sophisticated new analysis of team tactics predicts a Spanish win in Sunday's FIFA World Cup final and also shows why England were beaten by Germany. ... > full story
Miniature energy harvesting technology could power wireless electronics (July 9, 2010) -- Newly published research focuses on miniature energy harvesting technologies that could potentially power wireless electronics, portable devices, stretchable electronics, and implantable biosensors. ... > full story
Prospects for finding new Earths boosted by brand new planet-finding technique (July 9, 2010) -- Astronomers from Germany, Bulgaria and Poland have used a completely new technique to find an exotic extrasolar planet. The same approach is sensitive enough to find planets as small as the Earth in orbit around other stars. The group used Transit Timing Variation to detect a planet with 15 times the mass of the Earth in the system WASP-3, 700 light years from the Sun in the constellation of Lyra. ... > full story
