College Students Help Develop Small Satellite With Big PlansGreenbelt MD (SPX) Sep 21, 2010 Satellites are big. They cost a lot of money. At least that's the impression a couple of University of Maryland-College Park students had when they applied for an internship to help construct a satellite instrument with scientists at the NASA Goddard Space Flight Center in Greenbelt, Md. As the pair quickly discovered, nothing could have been farther from the truth. To their astonishment, the satellite that Saman Kholdebarin and Lida Ramsey helped to develop was literally the size of a football. " ... read more |

London (UPI) Sep 18, 2010 Britain's electrical system, financial networks and transport infrastructure could be paralyzed by a solar flare or a nuclear attack, a U.K. official says. U.K. Defense Secretary Liam Fox is expected to deliver that warning next week at a summit of scientists and security advisers who believe the infrastructure that underpins modern life in Western economies is potentially vulnerable to ... more  
Taipei, Taiwan (SPX) Sep 21, 2010Designers of robot pets are fighting a never-ending battle with consumers to provide entertaining and realistic gadgets that respond to human interaction in ever more nuanced ways, mimicking the behavior of real pet animals or even people. Researchers in Taiwan are now looking at a new design paradigm that could see the development of a robot vision module that might one-day recognize huma ... more  
Washington DC (SPX) Sep 21, 2010Piezoelectric materials have fantastic properties: squeeze them and they generate an electrical field. And vice-versa, they contract or expand when jolted with an electrical pulse. With a name derived from the Greek word meaning to squeeze or press, the piezoelectric effect was just a curiosity after it was discovered in several crystals in 1880. But in 1917, a quartz piezoelectric crystal ... more |

Physicists Control Chemical Reactions MechanicallyLos Angeles CA (SPX) Sep 21, 2010 UCLA physicists have taken a significant step in controlling chemical reactions mechanically, an important advance in nanotechnology, UCLA physics professor Giovanni Zocchi and colleagues report. Chemical reactions in the cell are catalyzed by enzymes, which are protein molecules that speed up reactions. Each protein catalyzes a specific reaction. In a chemical reaction, two molecules collide and exchange atoms; the enzyme is the third party, the "midwife to the reaction." But the molecules ... read more |
