Quantum tornado in the electron beam: Manipulating materials with rotating quantum particles (September 18, 2010) -- Researchers have succeeded in producing what are known as electron vortex beams: rotating electron beams, which make it possible to investigate the magnetic properties of materials. In the future, it may even be possible to manipulate the tiniest components in a targeted manner and set them in rotation. ... > full story
Synthetic fuels research aims to reduce oil dependence (September 18, 2010) -- Researchers have developed a facility aimed at learning precisely how coal and biomass are broken down in reactors called gasifiers as part of a project to strengthen the scientific foundations of the synthetic fuel economy. ... > full story
Fish schools and krill swarms take on common shape (September 18, 2010) -- When fish or tiny, shrimp-like krill get together, it appears they follow the same set of "rules." According to a new study, shoals of fish and swarms of krill hang out in groups that take on the same overall shape; it's not a simple sphere, a cylinder, or ovoid, but something more akin to an irregular crystal, the researchers say. ... > full story
Radiometric dating still reliable (again), research shows (September 18, 2010) -- Recent puzzling observations of tiny variations in nuclear decay rates have led some to question the science behind carbon-14 dating and similar techniques. However scientists tested the hypothesis that solar radiation might affect the rate at which radioactive elements decay and found no detectable effect. ... > full story
Physicists cross hurdle in quantum manipulation of matter (September 17, 2010) -- Finding ways to control matter at the level of single atoms and electrons fascinates many scientists and engineers because the ability to manipulate single charges and single magnetic moments (spins) may help researchers penetrate deep into the mysteries of quantum mechanics and modern solid-state physics. It may also allow development of new, highly sensitive magnetometers with nanometer resolution, single-spin transistors for coherent spintronics, and solid-state devices for quantum information processing. ... > full story
Pickle spoilage bacteria may help environment (September 17, 2010) -- Spoilage bacteria that can cause red coloration of pickles' skin during fermentation may actually help clean up dyes in textile industry wastewater, according to a new study. ... > full story
Less is more in the fight against terrorism (September 17, 2010) -- Terrorist networks are complex. Now, a mathematical analysis of their properties suggests that the best way to fight them is to isolate the hubs within the network rather than trying to destroy the network as a whole through short-term battles. ... > full story
New insights into the moon's rich geologic complexity (September 17, 2010) -- The moon is more geologically complex than previously thought, scientists report. Their conclusion is based on data from the Diviner Lunar Radiometer Experiment aboard NASA's Lunar Reconnaissance Orbiter, an unmanned mission to comprehensively map the entire moon. ... > full story
Moon's craters give new clues to early solar system bombardment (September 17, 2010) -- A first-ever uniform, comprehensive catalog of large craters on the Moon is providing new clues to the bombardment history that characterized the chaotic early days of the inner solar system. Researchers have identified and mapped more than 5,000 large craters, established the oldest regions on the moon, and confirmed a theory about past solar system bombardment. ... > full story
Cardiac imaging breakthrough developed (September 17, 2010) -- Cardiologists and surgeons may soon have a new tool to improve outcomes for patients requiring pacemakers, bypass surgery or angioplasties. Imaging research has led to a new process which provides a high resolution, 3-D image of the heart revealing not only its vasculature but also any scar tissue. ... > full story
Fungus among us could become non-food source for biodiesel production (September 17, 2010) -- In the quest for alternatives to soybeans, palm, and other edible oilseed plants as sources for biodiesel production, enter an unlikely new candidate: A fungus, or mold, that produces and socks away large amounts of oils that are suitable for low-cost, eco-friendly biodiesel. ... > full story
Hot water in cold comets: Water around comets produced with unusual properties (September 17, 2010) -- Comets, sometimes called “dirty snowballs”, are largely composed of water. An international research team recently succeeded in deciphering an important aspect of the way in which water molecules often form in space. As a surprise, the water molecules produced under cold, dilute conditions turned out to be produced as particles as hot as 60,000 Kelvin. In their research the physicists, though, did not use a telescope, but a particle accelerator. ... > full story
