How the Moon gets its exosphere (January 2, 2010) -- Several decades ago scientists discovered that the Moon, long thought to have no atmosphere, actually does have an extremely thin exosphere. Scientists generally believe that the ions that make up the lunar exosphere are generated at the Moon's surface by interaction with solar photons, plasma in the Earth's magnetosphere, or micrometeorites. However, scientists have been uncertain about which processes are the main contributors of lunar exosphere ions. ... > full story
Use of telemedicine for ICU patients not linked with improvement in survival (January 2, 2010) -- Remote monitoring of patients in intensive care units (ICUs) was not associated with an overall improvement in the risk of death or length of stay in the ICU or hospital, according to a new study. ... > full story
Making payments via cell phones (January 2, 2010) -- New security technology allows people to make payments via mobile phones. The technology is designed to work in almost all situations: person to person, in a shop or restaurant, at a vending machine, online, or as part of a telephone conversation. ... > full story
NASA's Mars rover Spirit has uncertain future as sixth anniversary nears (January 2, 2010) -- NASA's Mars rover Spirit will mark six years of unprecedented science exploration and inspiration for the American public on Jan. 3, 2010. However, the upcoming Martian winter could end the roving career of the beloved, scrappy robot. ... > full story
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
