NASA's WISE space telescope jettisons its cover (January 2, 2010) -- NASA's recently launched Wide-Field Infrared Survey Explorer (WISE) opened its eyes to the starry sky Dec. 29, after ejecting its protective cover. Engineers and scientists say the maneuver went off without a hitch, and everything is working properly. The mission's "first-light" images of the sky will be released to the public in about a month, after the telescope has been fully calibrated. ... > full story
Explaining plasma motion around Saturn (January 2, 2010) -- Understanding the motion and source of the plasma around Saturn is important for understanding the dynamics of the magnetosphere. Researchers present a theory that describes plasma transport in Saturn's magnetosphere, including processes that add new mass to the plasma and those that remove momentum from the plasma without changing plasma mass. ... > full story
Window opens into Moon's past volcanism (January 1, 2010) -- Lava tubes, underground cave-like channels through which lava once flowed, are commonly found on Earth. Scientists have debated whether these tubes could form on the Moon as well, but no studies have yet conclusively identified features that indicate the presence of lunar lava tubes. ... > full story
Quelling Casimir: Scientists to control quantum mechanical force (January 1, 2010) -- Scientists are developing a way to control the Casimir force, a quantum mechanical force that attracts objects when they are only hundred nanometers apart. ... > full story
Looking back in time 12 billion years with new instruments on Herschel Space Observatory (January 1, 2010) -- Astronomers have made the most detailed views yet of space up to 12 billion years back in time. ... > full story
A facial expression is worth a thousand words (December 31, 2009) -- Moving pictures are more suitable to interpret the mood of a person than a static photograph. Communication is a central aspect of everyday life, a fact that is reflected in the wide variety of ways that people exchange information, not only with words, but also using their face and body. Scientists have now found out that we are able to recognize facial expressions in motion far better than in a static photograph. The video sequence needs to be at least as long as one tenth of a second to gain this dynamic advantage. ... > full story
Moving video to 'captcha' robot hackers (December 31, 2009) -- Researchers have developed a synthesis technique that generates moving pictures of 3-D objects which will allow security developers to generate an infinite number of "emergence" images virtually impossible for any computer algorithm to decode. ... > full story
Lithium-air batteries could displace gasoline in future cars (December 31, 2009) -- In excess of seven million barrels of gasoline are consumed by vehicles in the United States every day. As scientists race to find environmentally sound solutions to fuel the world's ever-growing transportation needs, battery researchers are exploring the promise of lithium-air battery technology. ... > full story
New RNA interference technique can silence up to five genes (December 31, 2009) -- Researchers report that they have successfully used RNA interference to turn off multiple genes in the livers of mice, an advance that could lead to new treatments for diseases of the liver and other organs. ... > full story
How much ice needed to create Martian land formations? (December 31, 2009) -- Some land formations on Mars suggest the presence of water ice. These features could have been created by viscous creep of ice below the surface in Martian permafrost. To determine how much ice would be needed to form the observed topography on Mars, researchers conducted laboratory experiments to simulate the frozen Martian sand. ... > full story
New video reveals secrets of Webb Telescope's MIRI (December 31, 2009) -- It's going to take infrared eyes to see farther back in time than even the Hubble Space Telescope, and that's what the James Webb Space Telescope's MIRI or Mid-Infrared Instrument detectors will do. ... > full story
Saturn's auroral hiss is asymmetrical (December 31, 2009) -- Saturn emits "auroral hiss," a whistler-mode electromagnetic emission observed in the magnetosphere at high latitudes. This emission is similar to auroral hiss emitted by Earth. However, unlike Earth's auroral hiss, researchers have found that Saturn rotates in a beam-like matter around the planet. ... > full story
