Distant star's sound waves reveal cycle similar to the sun's (August 27, 2010) -- In a bid to unlock longstanding mysteries of the sun, including the impacts on Earth of its 11-year cycle, an international team of scientists has successfully probed a distant star. By monitoring the star's sound waves, the team has observed a magnetic cycle analogous to the sun's solar cycle. ... > full story
New model to help organize, keep private 'vast ocean' of social network data (August 27, 2010) -- Researchers have developed a new model to manage the "vast ocean" of user-generated content being generated by the ever-growing social networking sites including Facebook and Twitter. ... > full story
Shrinking atmospheric layer linked to low levels of solar radiation (August 27, 2010) -- Scientists link a recent, temporary shrinking of a high atmospheric layer with a sharp drop in the sun's ultraviolet radiation levels. ... > full story
NASA's Kepler mission discovers two planets transiting same star (August 27, 2010) -- NASA's Kepler spacecraft has discovered the first confirmed planetary system with more than one planet crossing in front of, or transiting, the same star. ... > full story
Prediction of intrinsic magnetism at silicon surfaces could lead to single-spin magnetoelectronics (August 27, 2010) -- The integration of single-spin magnetoelectronics into standard silicon technology may soon be possible, if experiments confirm a new theoretical prediction made by physicists. ... > full story
NASA's SOFIA will likely help solve mysteries about our galaxy (August 27, 2010) -- How were millions of young stars able to form at the center of our Milky Way galaxy in the presence of an enormous black hole with a mass 4 million times that of the sun? This and other important questions may be answered by the NASA mission SOFIA, which is scheduled to make its first scientific measurements in the next few months. ... > full story
Scientists concerned about environmental impact of recycling of e-waste (August 27, 2010) -- Much of the world's electronic waste is being shipped to China for recycling and the cottage industry that has sprung up there to recover usable materials from computers, cell phones, televisions and other goods may be creating significant health and environmental hazards. ... > full story
First 3-D atomic view of key genetic processes (August 27, 2010) -- Scientists have created the first 3-D picture of genetic processes that happen inside every cell of our bodies. The picture is the first-ever image of a protein interacting with DNA in its tightly packed "nucleosome" form. The research, which reveals new information about genetic processes, is expected to aid future investigations into diseases such as cancer. ... > full story
'Greening' your flat screen TV: Engineers develop an organic LED light source for home electronics, medicine and clean energy (August 27, 2010) -- An estimated 70 percent of heavy metals in US landfills come from discarded electronics, and as big screen TVs get less expensive, environmental costs continue to mount. To remedy this, researchers are applying organic nano-technology to "green" the optics and electronics industry. Their technology could make flat screen TV production more environmentally friendly and can even make medical devices more sensitive. ... > full story
Ten years flying in formation: The legendary Cluster quartet (August 27, 2010) -- Next week marks the 10th anniversary of the start of formation flying for the four satellites of ESA's Cluster quartet, one of the most successful scientific missions ever launched. On 1 September 2000, just a few weeks after launch, the four individual satellites of the Cluster mission began coordinated orbits, marking the formal start of formation flying. Since then, the four satellites -- dubbed Samba, Tango, Rumba and Salsa -- have gone on to collect some of the most detailed data ever on the physical properties of space between Earth and the Sun, and on the interactions between the charged particles of the solar wind and Earth's atmosphere. In all, over 2.6 terabytes of data -- enough to fill 3300 CDROMS -- have been delivered from space. ... > full story
Some asteroids live in own little worlds (August 26, 2010) -- While the common perception of asteroids is that they are giant rocks lumbering about in orbit, a new study shows they actually are constantly changing "little worlds" that can give birth to smaller asteroids that split off to start their own lives as they circle around the sun. ... > full story
Tofu ingredient yields formaldehyde-free glue for plywood and other wood products (August 26, 2010) -- In a real-life "back to the future" story, scientists have reported that the sustainable, environmentally-friendly process that gave birth to plywood a century ago is re-emerging as a "green" alternative to wood adhesives made from petroleum. Researchers have described development of new soy-based glues that use a substance in soy milk and tofu and could mean a new generation of more eco-friendly furniture, cabinets, flooring and other wood products. ... > full story
