Wind and water have shaped Schiaparelli impact basin on Mars (December 11, 2010) -- The small crater embedded in the northwestern rim of the Schiaparelli impact basin features prominently in this new image from the European Space Agency's Mars Express. All around is evidence for past water and the great martian winds that periodically blow. ... > full story
Computer-based program may help relieve some ADHD symptoms in children (December 11, 2010) -- An intensive, five-week working memory training program shows promise in relieving some of the symptoms of attention deficit hyperactivity disorder in children, a new study suggests. Researchers found significant changes for students who completed the program in areas such as attention, ADHD symptoms, planning and organization, initiating tasks and working memory. ... > full story
Neutron stars and string theory in a lab: Chilled atoms give clues to deep space and particle physics (December 11, 2010) -- Using lasers to contain some ultra-chilled atoms, a team of scientists has measured the viscosity or stickiness of a gas often considered to be the sixth state of matter. The measurements verify that this gas can be used as a "scale model" of exotic matter, such as super-high temperature superconductors, the nuclear matter of neutron stars, and even the state of matter created microseconds after the Big Bang. The results may also allow experimental tests of string theory in the future. ... > full story
Simulations aim to unlock nature's process of biomineralization (December 11, 2010) -- Researchers are leveraging advanced modeling and simulation resources to study the process of biomineralization, nature's ability to form complex structures, such as bones, teeth and mollusk shells. This natural phenomenon, if harnessed, could lead to the design of composite materials and devices for such applications as bone replacement, sensing systems, efficient energy generation and treatment of diseases. ... > full story
WISE sees an explosion of infrared light (December 10, 2010) -- A circular rainbow appears like a halo around an exploded star in a new view of the IC 443 nebula from NASA's Wide-field Infrared Survey Explorer, or WISE. When massive stars die, they explode in tremendous blasts, called supernovae, which send out shock waves. The shock waves sweep up and heat surrounding gas and dust, creating supernova remnants like the one pictured in the new image. The supernova in IC 443 happened somewhere between 5,000 and 10,000 years ago. ... > full story
Odyssey orbiter nears Martian longevity record (December 10, 2010) -- By the middle of next week, NASA's Mars Odyssey orbiter will have worked longer at Mars than any other spacecraft in history. Odyssey made its most famous discovery -- evidence for copious water ice just below the dry surface of Mars -- during its first few months, and it finished its radiation-safety check for future astronauts before the end of its prime mission in 2004. The bonus years of extended missions since then have enabled many accomplishments that would not have been possible otherwise. ... > full story
Winter treat for skywatchers as Geminid meteors sparkle in December sky (December 10, 2010) -- On the evening of December 13th and the morning of the 14th, skywatchers across the northern hemisphere will be looking up as the Geminid meteor shower reaches its peak, in one of the best night sky events of the year. And unlike many astronomical phenomena, meteors are best seen without a telescope (and are perfectly safe to watch). ... > full story
World's smallest battery: Real-time observation of nanowire anode to help improve lithium batteries (December 10, 2010) -- A benchtop version of the world's smallest battery -- its anode a single nanowire one seven-thousandth the thickness of a human hair -- has been created by a team of researchers. ... > full story
Bioengineers develop bacterial strain to increase ethanol biofuel production (December 10, 2010) -- Bioengineers have modified a strain of bacteria to increase its ability to produce ethanol. The research reveals how adaptation and metabolic engineering can be combined for strain improvement, a positive development for the biofuel industry. ... > full story
Seeing the invisible: New 'CSI tool' visualizes bloodstains and other substances (December 10, 2010) -- Snap an image of friends in front of a window curtain and the camera captures the people -- and invisible blood stains splattered on the curtain during a murder. Sound unlikely? Chemists are reporting development of a camera with that ability to see the invisible, and more. Called multimode imaging in the thermal infrared, the new technology could find uses in crime scene investigations and elsewhere, they say. ... > full story
New insights into formation of Earth, the Moon, and Mars (December 10, 2010) -- New research reveals that the abundance of so-called highly siderophile, or metal-loving, elements like gold and platinum found in the mantles of Earth, the moon and Mars were delivered by massive impactors during the final phase of planet formation over 4.5 billion years ago. The predicted sizes of the projectiles, which hit within tens of millions of years of the giant impact that produced our moon, are consistent with current planet formation models. They predict that the largest of the late impactors on Earth -- at 1,500 to 2,000 miles in diameter -- potentially modified Earth's obliquity by approximately 10 degrees, while those for the Moon, at approximately 150-200 miles, may have delivered water to its mantle. ... > full story
Perfectly needled nonwoven (December 10, 2010) -- Hardly any other textile is as versatile as nonwoven: it keeps babies' bottoms dry and protects plants from the sun. In the Gulf of Mexico, special nonwovens soaked up the oil washed up on beaches like blotting paper. A new piece of simulation software now makes it possible to produce high-quality, stripe-free nonwoven fabrics. ... > full story
