Plants play larger role than thought in cleaning up air pollution, research shows (October 22, 2010) -- Vegetation plays an unexpectedly large role in cleansing the atmosphere, a new study finds. The research uses observations, gene expression studies, and computer modeling to show that deciduous plants absorb about a third more of a common class of air-polluting chemicals than previously thought. ... > full story
Protein injection shows promise in lowering elevated triglycerides (October 22, 2010) -- A protein injection reduced high triglyceride levels in one type of genetically engineered mice, a new study has found. The approach might help people with similar genetic alterations that cause very high triglycerides. ... > full story
New cometary phenomenon greets approaching spacecraft (October 22, 2010) -- Recent observations of comet Hartley 2 have scientists scratching their heads, while they anticipate a flyby of the small, icy world on Nov. 4. A phenomenon was recorded by imagers aboard NASA's Deep Impact spacecraft from Sept. 9 to 17 during pre-planned scientific observations of the comet. These observations, when coupled with expected images during the closest encounter with Hartley 2 on Nov. 4, will become the most detailed look yet at a comet's activity during its pass through the inner-solar system. ... > full story
Succimer found ineffective for removing mercury (October 22, 2010) -- Succimer, a drug used for treating lead poisoning, does not effectively remove mercury from the body, according to new research. Some families have turned to succimer as an alternative therapy for treating autism. ... > full story
Value-added sulfur scrubbing: Converting acid rain chemicals into useful products (October 22, 2010) -- Power plants that burn fossil fuels remain the main source of electricity generation across the globe. Modern power plants have scrubbers to remove sulfur compounds from their flue gases, which has helped reduce the problem of acid rain. Now, researchers in India have devised a way to convert the waste material produced by the scrubbing process into value-added products. ... > full story
70-year-olds smarter than they used to be, Swedish study finds (October 22, 2010) -- Today's 70-year-olds do far better in intelligence tests than their predecessors. It has also become more difficult to detect dementia in its early stages, though forgetfulness is still an early symptom, reveals new research from Sweden, based on the H70 study. ... > full story
Space telescopes reveal previously unknown brilliant X-ray explosion in Milky Way galaxy (October 22, 2010) -- Astronomers in Japan, using an X-ray detector on the International Space Station, and in the United States, using NASA's Swift space observatory, are announcing the discovery of an object newly emitting X-rays, which previously had been hidden inside our Milky Way galaxy in the constellation Centaurus. ... > full story
Skin cancer linked to loss of protein that hooks skin cells together (October 22, 2010) -- In a new study, researchers have implicated the lack of a protein important in hooking our skin cells together in the most common variety of skin cancer. ... > full story
Another winter of extremes in store for U.S. as La Niña strengthens (October 22, 2010) -- The Pacific Northwest should brace for a colder and wetter than average winter, while most of the South and Southeast will be warmer and drier than average through February 2011, according to the annual Winter Outlook released by NOAA's Climate Prediction Center. A moderate to strong La Niña will be the dominant climate factor influencing weather across most of the U.S. this winter. ... > full story
Scorpion has welcome sting for heart bypass patients (October 22, 2010) -- A toxin found in the venom of the Central American bark scorpion (Centruroides margaritatus) could hold the key to reducing heart bypass failures, according to new research. ... > full story
Researchers break speed barrier in solving important class of linear systems (October 22, 2010) -- Computer scientists have devised an innovative and elegantly concise algorithm that can efficiently solve systems of linear equations that are critical to such important computer applications as image processing, logistics and scheduling problems, and recommendation systems. ... > full story
Positive social traits trump bad health habits, new study finds (October 22, 2010) -- Many studies have documented the dangers of the traditional negative physical risk factors on health -- excessive smoking, drinking and being overweight. But far less research has focused on less-tangible, positive influences -- the protective role of psychological and social supports. ... > full story
