Radiation expert discusses Japan nuclear power plant concerns (March 11, 2011) -- Following Friday's massive 8.9-magnitude earthquake that caused tsunamis and rocked the island nation of Japan, Japanese government officials announced a nuclear emergency after the quake caused a reactor cooling system malfunction at Fukushima No. 1 Nuclear Power Plant. ... > full story
Near-real-time map of Japan quake aftershocks (March 11, 2011) -- Researchers have created a near-real-time map of the aftershocks occurring globally following the 8.9 magnitude earthquake that rocked Japan Friday. ... > full story
Speed demon star creates a shock (March 11, 2011) -- Just as some drivers obey the speed limit while others treat every road as if it were the Autobahn, some stars move through space faster than others. NASA's Wide-field Infrared Survey Explorer, or WISE, captured a new image of the star Alpha Camelopardalis speeding through the sky like a motorcyclist zipping through rush-hour traffic. ... > full story
The most distant mature galaxy cluster: Young, but surprisingly grown-up (March 11, 2011) -- Astronomers have discovered and measured the distance to the most remote mature cluster of galaxies yet found. Although this cluster is seen when the universe was less than one quarter of its current age it looks surprisingly similar to galaxy clusters in the current universe. ... > full story
Snails' complex muscle movements, rather than mucus, key to locomotion (March 11, 2011) -- New evidence suggests that the key to locomotion in snails stems from the animal's complex muscle movements, and not from its mucus, as had been previously thought. This finding could open the door to the construction of robots which could imitate this form of propulsion. ... > full story
New method for studying molecule reactions a breakthrough in organic chemistry (March 11, 2011) -- In a feat of manipulating substances at the nanoscale, new research demonstrates a method to isolate two molecules together on a substrate and to control specifically how those two molecules react when excited with ultraviolet light, further making detailed observations before and after reaction. The method mimics the strategy used by enzymes in many biochemical reactions. ... > full story
New technology would dramatically extend battery life for mobile devices (March 11, 2011) -- Technophiles who have been dreaming of mobile devices that run longer on lighter, slimmer batteries may soon find their wish has been granted. Engineers have developed a form of ultra-low-power digital memory that is faster and uses 100 times less energy than similar available memory. The technology could give future portable devices much longer battery life between charges. The researchers use carbon nanotubes as electrodes and tiny amounts of phase-change material as the bit. ... > full story
New robot system to test 10,000 chemicals for toxicity (March 11, 2011) -- Several federal agencies have unveiled a new high-speed robot screening system that will test 10,000 different chemicals for potential toxicity. The system marks the beginning of a new phase of an ongoing collaboration, referred to as Tox21, that is working to protect people's health by improving how chemicals are tested in this country. ... > full story
Half-time for Mars500: Simulated mission to the Red Planet (March 11, 2011) -- The Mars500 mission -- a simulated mission to the Red Planet -- has reached its half-way mark: After a 250-day virtual flight, the crew members recently landed on a virtual Mars and left the isolation container at the Moscow Institute of Biomedical Problems (IBMP) in their space suits. ... > full story
How do people respond to being touched by a robotic nurse? (March 10, 2011) -- Researchers have found people generally had a positive response toward being touched by a robotic nurse, but that their perception of the robot's intent made a significant difference. ... > full story
Defective plastics repair themselves (March 10, 2011) -- Indestructible things are a figment of the imagination of advertising. Even plastic components that have to stand up to major mechanical loads can break. The reason for this are microcracks that may be found in any component part. Researchers have now come up with elastic polymers that heal themselves to put an end to the growth of cracks. ... > full story
Work climate the main reason women leave engineering, survey suggests (March 10, 2011) -- After years of investing in strategies to encourage more women to pursue a rigorous engineering degree -- and succeeding -- US engineering firms are now facing a problem in retaining qualified women engineers. Why are so many women leaving the field -- or getting their degrees but never entering the field? The top reason isn't family, according to a new study, but an unfavorable work climate. ... > full story
