Night light pollution affect songbirds' mating life, research suggests (September 18, 2010) -- In today's increasingly urbanized world, the lights in many places are always on, and according to a new study, that's having a real impact on the mating life of forest-breeding songbirds. ... > full story
Tick tock: Rods help set internal clocks, biologist says (September 18, 2010) -- Rod cells -- one of three kinds of exquisitely photosensitive cells found in the retina of the eye -- are surprisingly found to be the only ones responsible for setting our internal "clocks" in low light. ... > 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
NASA uses new method to estimate Earth mass movements (September 18, 2010) -- NASA and European researchers have conducted a novel study to simultaneously measure, for the first time, trends in how water is transported across Earth's surface and how the solid Earth responds to the retreat of glaciers following the last major Ice Age, including the shifting of Earth's center of mass. ... > full story
U.S. tsunami detection improves, but coastal areas still vulnerable, report finds (September 18, 2010) -- The nation's ability to detect and forecast tsunamis has improved since the 2004 Indian Ocean tsunami, but current efforts are still not sufficient to meet challenges posed by tsunamis generated near land that leave little time for warning, says a new report. ... > 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
When Earth's mantle meets its core: Findings boost hypothesis of deep magma ocean (September 17, 2010) -- Earth's mantle and its core mix at 2900 kilometers under our feet in a mysterious zone. A team of geophysicists has just verified that the partial fusion of the mantle is possible in this area when the temperature reaches 4200 Kelvin. This reinforces the hypothesis of the presence of a deep magma ocean. The results have an effect in the understanding of the dynamics, composition and formation of the depths of our planet. ... > 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
Foraging for fat: Crafty crows use tools to fish for nutritious morsels (September 17, 2010) -- Researchers have used CSI-style analysis to reveal the huge benefits conferred on New Caledonian crows through tool use. Their results give hard evidence of the huge evolutionary advantage that can be gained by tool use -- giving an insight into the importance of tool use in survival. ... > full story
Veterinarian says natural foods not always best for pets (September 17, 2010) -- While natural food is a rising trend among humans, pet owners should be careful before feeding similar types of food to their pets, according to a veterinarian. ... > full story
