Precise trace gas analysis, without the noise (May 30, 2010) -- Analyzing trace atmospheric gases can now be considerably more precise with the help of a device that delivers stable and reliable power to the lasers used in gas sensors. ... > full story
Improved carbon sponges to strip carbon dioxide from power plant exhausts (May 29, 2010) -- A new class of materials with a record-shattering internal surface area may have the right stuff to efficiently strip carbon dioxide from a power plant's exhaust. ... > full story
Researcher decodes Rembrandt's 'magic' (May 29, 2010) -- A researcher using computer-rendering programs has uncovered what makes Rembrandt's masterful portraits so appealing. Rembrandt may have pioneered a technique that guides the viewer's gaze around a portrait, creating a special narrative and "calmer" viewing experience. ... > full story
Clue to origin of Milky Way gas clouds discovered (May 29, 2010) -- A study of hydrogen gas clouds in two different regions of the Milky Way shows that they are much more abundant above areas of intense star formation, indicating they are blown away from the Galaxy's plane by stellar winds and supernova explosions. ... > full story
Zeroing in on quantum effects: New materials yield clues about high-temperature superconductors (May 29, 2010) -- US and Chinese physicists are zeroing in on critical effects at the heart of the newest high-temperature superconductors, the family of iron-based compounds called "pnictides." The scientists used similarly structured materials called "oxychalcogenides" to investigate the effect of expanding the distance between iron atoms in the crystal lattice. ... > full story
'Law-like' mathematical patterns in human preference behavior discovered (May 28, 2010) -- Scientists have found mathematical patterns underlying the way individuals unconsciously distribute their preferences regarding approaching or avoiding objects in their environment. These patterns appear to meet the strict criteria used to determine whether something is a scientific law and, if confirmed in future studies, could potentially be used to guide diagnosis and treatment of psychiatric disorders. ... > full story
Toward a useful quantum computer: Researchers design and test microfabricated planar ion traps (May 28, 2010) -- Researchers are designing, fabricating and testing planar ion traps that can be more readily combined into large, interconnected trap arrays. In the future, these arrays may be used to create a useful quantum computer. ... > full story
Novel 'cuckoo search algorithm' beats particle swarm optimization in engineering design (May 28, 2010) -- The familiar early summer call of the cuckoo has inspired composer and poet alike, but the sound belies the bird's true parasitic nature. Now, researchers have taken the cuckoo's wont to deposit its eggs in the nests of other birds as inspiration for a new approach to engineering design. ... > full story
Planetary scientists solve 40-year-old mysteries of Mars' northern ice cap (May 28, 2010) -- Scientists have reconstructed the formation of two curious features in the northern ice cap of Mars -- a chasm larger than the Grand Canyon and a series of spiral troughs -- solving a pair of mysteries dating back four decades while finding new evidence of climate change on Mars. ... > full story
Electric supercar team aims for UK first in lead-up to world record attempt across the Americas (May 28, 2010) -- Students driving an electric supercar are attempting to be the first to drive an all-electric vehicle around the M25 twice on one battery charge, in the lead-up to the team's attempt to cross the Americas in July this year and break a world record. ... > full story
Electric ash found in Eyjafjallajokull's plume, say UK researchers (May 28, 2010) -- In the first peer-reviewed scientific paper to be published about the Icelandic volcano since its eruption in April 2010, UK researchers write that the ash plume which hovered over Scotland carried a significant and self-renewing electric charge. ... > full story
Advances made in walking, running robots (May 28, 2010) -- Researchers have made an important fundamental advance in robotics, in work that should lead toward robots that not only can walk and run effectively, but use little energy in the process. By achieving an optimal approach with robotic mechanisms, studies are moving closer to robots that could take on dangerous missions in the military, create prosthetic limbs for humans that work much better, or even help some people who use wheelchairs to gain "walking" abilities. ... > full story
