Tiny logo demonstrates advanced display technology using nano-thin metal sheets (August 28, 2010) -- In a step toward more efficient, smaller and higher-definition display screens, a researcher has developed a new type of color filter made of nano-thin sheets of metal with precisely spaced gratings. ... > full story
Secrets of the gecko foot help robot climb (August 28, 2010) -- The science behind gecko toes holds the answer to a dry adhesive that provides an ideal grip for robot feet. A mechanical engineer is using the new material, based on the structure of a gecko foot, to keep his robots climbing. ... > full story
Medicine reaches the target with the help of magnets (August 28, 2010) -- If a drug can be guided to the right place in the body, the treatment is more effective and there are fewer side-effects. Researchers in Sweden have now developed magnetic nanoparticles that can be directed to metallic implants such as artificial knee joints, hip joints and stents in the coronary arteries. ... > full story
Surgical robot could be used for long-distance regional anesthesia (August 28, 2010) -- An existing surgical robot could be used to perform complex regional anesthesia procedures -- in theory, allowing expert anesthesiologists to perform robot-assisted procedures from remote locations, according to a new study. ... > full story
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
