New elastic material changes color in UV light (April 16, 2011) -- Researchers have created a range of soft, elastic gels that change color when exposed to ultraviolet (UV) light -- and change back when the UV light is removed or the material is heated up. ... > full story
Solar activity heats up: Sunspots finally return (April 16, 2011) -- As 2011 unfolds, sunspots have returned and they are crackling with activity. On February 15 and again on March 9, Earth orbiting satellites detected a pair of "X-class" solar flares -- the most powerful kind of X-ray flare. ... > full story
Novel ionic liquid batteries (April 15, 2011) -- Limits imposed by using corrosive electrolytes often result in severe restrictions to battery geometry and the need for special corrosive-resistant battery containers. The use of reactive ionic liquids in non-aqueous cells replace the more hazardous highly alkaline electrolytes. ... > full story
New spin on graphene makes it magnetic (April 15, 2011) -- Scientists have found a way to make wonder material graphene magnetic, opening up a new range of opportunities for the world's thinnest material in the area of spintronics. ... > full story
A bicycle built for none: Riderless bike helps researchers learn how balance rolls along (April 15, 2011) -- In a discovery that could lead to better and safer bicycle design, researchers have shown that long-accepted "gyro" and "caster" effects are not needed to make a bike balance itself. In fact, it's a mixture of complicated physical effects -- linked to the distribution of mass -- that allows a bicycle to remain up when moving. ... > full story
Forest byproducts, shells may be key to removing radioactive contaminants from drinking water (April 15, 2011) -- A combination of forest byproducts and crustacean shells may be the key to removing radioactive materials from drinking water, researchers have found. ... > full story
Carbon fiber used to reinforce buildings; protect from explosion (April 15, 2011) -- Most buildings are not constructed to withstand an unexpected explosion or impact. Now, a researcher is working with the US Army to test a method of retrofitting buildings to protect them in the case of a terrorist attack. ... > full story
Fast-rotating asteroid winks for astronomer's camera (April 15, 2011) -- Video imaging of newly discovered asteroid 2011 GP59 shows the object appearing to blink on and off about once every four minutes. ... > full story
WISE delivers millions of galaxies, stars, asteroids (April 15, 2011) -- Astronomers across the globe can now sift through hundreds of millions of galaxies, stars and asteroids collected in the first bundle of data from NASA's Wide-field Infrared Survey Explorer (WISE) mission. ... > full story
Search for dark matter moves one step closer to detecting elusive particle (April 15, 2011) -- Dark matter, the mysterious substance that may account for nearly 25 percent of the universe, has so far evaded direct observation. But researchers participating in the international XENON collaboration say they are now closer than ever before. ... > full story
Sensor determines if packaged meat has spoiled (April 15, 2011) -- When it comes to packaged fish or meat, it is nearly impossible to distinguish between fresh goods and their inedible counterparts. Researchers have now developed a sensor film that can be integrated into the package itself, where it takes over the role of quality control. And if the food has spoiled, it changes color to announce the fact. ... > full story
NASA's next generation space telescope marks key milestone (April 15, 2011) -- The first six of 18 segments that will form NASA's James Webb Space Telescope's primary mirror for space observations will begin final round-the-clock cryogenic testing this week. These tests will confirm the mirrors will respond as expected to the extreme temperatures of space prior to integration into the telescope's permanent housing structure. ... > full story
