PARSONS, W. Va., September 12, 2012 – Using old deeds and witness trees, a U.S. Forest Service scientist has created a glimpse of the composition of the forests that covered today's Monongahela National Forest before settlement and logging changed the landscape. "European Settlement-Era Vegetation of the Monongahela National Forest, West Virginia" describes how a Forest Service scientist and her West Virginia University colleague answered questions about the composition of early forests using a unique dataset. The dataset was built with original deeds, metes and bounds ...

Vegas, Monte Carlo, and Atlantic City draw people from around the world who are willing to throw the dice and take their chances. Researchers from the Technical University of Lodz, Poland, have spotted something predictable in the seemingly random throw of the dice. By applying chaos theory and some high school level mechanics, they determined that by knowing the initial conditions – such as the viscosity of the air, the acceleration of gravity, and the friction of the table – it should be possible to predict the outcome when rolling the dice. The researchers created ...

New research from the Hebrew University of Jerusalem shows that a carefully scheduled high-fat diet can lead to a reduction in body weight and a unique metabolism in which ingested fats are not stored, but rather used for energy at times when no food is available. The research was conducted by Prof. Oren Froy along with Prof. Zecharia Madar, research student Yoni Genzer and research fellow Dr. Hadas Sherman at the Institute of Biochemistry, Food Science and Nutrition, at the Hebrew University's Robert H. Smith Faculty of Agriculture, Food and Environment. The results ...

Furthermore, it is possible to predict which ...

OTTAWA, Canada, September 12, 2012—Vitamin D is increasingly being recognized as important for good health. Vitamin D is a hormone made in the skin following sun exposure or acquired from diet and supplement intake. Previous medical research has shown that low body levels of vitamin D make people more susceptible to problems such as bone fractures, poor mental health and infections like the common cold. Until recently, there had been little consideration given to the role of vitamin D in more severe diseases, which is why Dr. Dayre McNally's recent publication in the esteemed ...

CINCINNATI – New research indicates marijuana-like compounds called endocannabinoids alter genes and biological signals critical to the formation of a normal placenta during pregnancy and may contribute to pregnancy complications like preeclampsia. A study in the Sept. 14 edition of The Journal of Biological Chemistry offers new evidence that abnormal biological signaling by endocannabinoid lipid molecules produced by the body disrupts the movement of early embryonic cells important to a healthy pregnancy, in particular trophoblast cells that form the placenta. Abnormal ...

In an advance toward development of a nasal spray that protects against infection with influenza and spread of the disease, scientists are reporting identification of a substance that activates the first-line defense system against infection inside the nose. They describe effects of a synthetic form of a natural substance found in bacterial cell walls in ACS' journal Molecular Pharmaceutics. David C. Jackson and colleagues explain that the body's so-called innate immune system forms a first-line defense system against respiratory diseases like influenza A — which causes ...

People in the United States took more prescription drugs than ever last year, with the number of prescriptions increasing from 3.99 billion (with a cost of $308.6 billion) in 2010 to 4.02 billion (with a cost of $319.9 billion) in 2011. Those numbers and others appear in an annual profile of top prescription medicines published in the journal ACS Chemical Neuroscience. Journal Editor-in-Chief Craig W. Lindsley analyzed data on 2011 drugs with a focus on medications for central nervous system (CNS) disorders. So-called antipsychotic medicines — including those used to ...

The distribution system piping in U.S. public water systems that rely on non-disinfected well water or "ground water" may be a largely unrecognized cause of up to 1.1 million annual cases of acute gastrointestinal illness (AGI), involving nausea, vomiting and diarrhea, scientists are reporting. Their study in ACS' journal Environmental Science & Technology concludes that such illnesses may become more of a problem as much of the nation's drinking water supply system continues to age and deteriorate. Frank J. Loge, Mark A. Borchardt and colleagues explain that more than ...

EAST LANSING, Mich. — The brutally repressive Soviet Union Vladimir Shlapentokh left behind 33 years ago may have opened its borders to the world, but today's Russia has become wracked with greed, corruption and mass emigration that threaten the nation's future. So argues Shlapentokh, a Michigan State University sociologist, in the academic journal Communist and Post-Communist Studies. "As Russia's plight shows, the assumption that openness and liberalization automatically promote democracy and guarantee it will function turned out to be wrong," Shlapentokh said. "It ...

WASHINGTON -- Glaciers in the eastern and central regions of the Himalayas appear to be retreating at accelerating rates, similar to those in other areas of the world, while glaciers in the western Himalayas are more stable and could be growing, says a new report from the National Research Council. The report examines how changes to glaciers in the Hindu Kush-Himalayan region, which covers eight countries across Asia, could affect the area's river systems, water supplies, and the South Asian population. The mountains in the region form the headwaters of several major ...

Many high-achieving students experience math anxiety at a young age — a problem that can follow them throughout their lives, new research at the University of Chicago shows. In a study of first- and second-graders, Sian Beilock, professor in psychology, found that students report worry and fear about doing math as early as first grade. Most surprisingly math anxiety harmed the highest-achieving students, who typically have the most working memory, Beilock and her colleagues found. "You can think of working memory as a kind of 'mental scratchpad' that allows us to 'work' ...

Philadelphia, PA, September 12, 2012 – Glucocorticoids, a group of hormones that includes cortisol, are considered stress hormones because their levels increase following stress. When their relationship to stress was first identified, it was shown that the release of cortisol prepared the body to cope with the physical demands of stress. Subsequently, high levels of cortisol were linked to depression and other stress-related disorders, giving rise to the hypothesis that high levels of cortisol on a long-term basis may impair the psychological capacity to cope with stress. ...

MEDFORD/SOMERVILLE, MASS. – In a study that analyzed relationships between air quality and unemployment levels, a Tufts University researcher has developed a new statistical model that retrospectively estimates air pollution exposure for previous time periods where such information is not available. Mary Davis, an associate professor of urban and environmental policy and planning at Tufts University School of Arts and Sciences, analyzed traffic-related air pollution levels and unemployment rates in four separate regions of California for which extensive air monitoring ...

BOSTON, MA—Headache? Back pain? At the first sign of pain, you might reach for a pain-relieving medicine to sooth your bodily woes. Analgesics are the most frequently used medications in the United States and are commonly used to treat a variety of medical conditions. But although popping a pill may make the pain go away, it may do some damage to your ears. According to a study by researchers at Brigham and Women's Hospital (BWH), women who took ibuprofen or acetaminophen two or more days per week had an increased risk of hearing loss. The more often a woman took ...

GPs are not always using the most comprehensive and reliable online resources to support them in treating patients with the debilitating hearing condition tinnitus, researchers have found. The study looked at the 10 main websites used by GPs to get information on clinical practice and found that the two best websites for assessing or managing tinnitus — Map of Medicine and the British Tinnitus Association (BTA) — were rarely used by family doctors, with only two per cent logging on to access their pages. The research, which involved a team of experts from The University ...

NEW YORK -- September 12, 2012 -- The musician Paul Simon came to fame collaborating with his childhood friend Art Garfunkel, yet launched another chapter with his Graceland album, collaborating with musicians from Soweto. Ratan Tata made his name expanding his family's firms in India, yet in recent decades has reached even greater success helping foreign firms such as Daewoo and Jaguar find new markets. Whether artists, entrepreneurs, or executives, some individuals are especially able to bridge cultural gaps and leverage foreign ideas and opportunities. Why can some ...

So many acts in our daily lives – refusing that second slice of cake, walking past the store with the latest gadgets, working on your tax forms when you'd rather watch TV – seem to boil down to one essential ingredient: self-control. Self-control is what enables us to maintain healthy habits, save for a rainy day, and get important things done. But what is self-control, really? And how does it work? In a new article in the September 2012 issue of Perspectives on Psychological Science, a journal of the Association for Psychological Science, researchers Michael Inzlicht ...
