Slight change in wind turbine speed significantly reduces bat mortality

2010-11-02
While wind energy has shown strong potential as a large-scale, emission-free energy source, bat and bird collisions at wind turbines result in thousands of fatalities annually. Migratory bats, such as the hoary bat, are especially at risk for collision with wind turbines as they fly their routes in the forested ridges of the eastern U.S. This loss not only impacts the immediate area, but is also detrimental to ecosystem health nationwide—that is, bats help with pest management, pollination and the dispersal of numerous plant seeds. Since turbine towers and non-spinning ...

Voting-machine-allocation method could reduce voters' wait time by 36 percent

Voting-machine-allocation method could reduce voters wait time by 36 percent
2010-11-02
With a lifelong interest in politics, University of Cincinnati researcher Muer Yang spent the last two years developing a quantitative method for allocating voting machines that could significantly reduce the average wait time of voters. During the 2004 U.S. presidential elections, some voters waited in lines for more than 10 hours to cast their ballots, and in Ohio, the last vote was cast at 4 a.m., noted Ohio Secretary of State Jennifer Brunner in a public report. Ohio lines in the '06 and '08 elections were still so lengthy that they essentially "disenfranchised" voters ...

Study: Race plays a minor role in forging Facebook friendships

2010-11-02
CAMBRIDGE, Mass., Nov. 1, 2010 -- Race may not be as important as previously thought in determining who befriends whom, suggests a new study of American college students' habits on Facebook. The findings, by a pair of sociologists from Harvard University and UCLA, appear in the current issue of the American Journal of Sociology. The strongest attraction, the researchers found, turned out to be old-fashioned social pressure. For the average student, the tendency to reciprocate a friendly overture is seven times stronger than the attraction of a shared racial background. "We ...

King crab distributions limited by temperature in the Southern Ocean
2010-11-02
Invasions of voracious predatory crabs due to global warming could threaten the unique continental-shelf ecosystems of Antarctica, according to newly published findings. "King crabs are ecologically important predators and form the basis of economically significant commercial fisheries," said Dr Sven Thatje, an evolutionary ecologist at the University of Southampton's School of Ocean and Earth Science (SOES), which is based at the National Oceanography Centre in Southampton. Thatje and graduate student Sally Hall studied how water temperature influences the distributions ...

Scientists find that evergreen agriculture boosts crop yields

2010-11-02
THE HAGUE (2 November 2010)—A unique acacia known as a "fertilizer tree" has typically led to a doubling or tripling of maize yields in smallholder agriculture in Zambia and Malawi, according to evidence presented at a conference in the Hague today. The findings were central to the arguments of agroforestry experts at the conference, who urged decision makers to spread this technology more widely throughout the African nations most vulnerable to climate change and food shortages, and to think differently about more practical ways to solve the problems that are most pressing ...

At great expense, railroad bypassed first black-founded town in the US

At great expense, railroad bypassed first black-founded town in the US
2010-11-02
CHAMPAIGN, lll.— Ignoring topography, efficiency, expense and even their own surveyors' recommendations, regional railroad officials in the mid-19th century diverted a new rail line around New Philadelphia, Ill., "the first town in the United States planned, platted and legally registered by an African American," a University of Illinois researcher reports. The bypass pushed what would have been a fairly straight, even run of railroad tracks from Griggsville, Ill. to Hannibal, Mo., in a wide, hilly arc around New Philadelphia. The findings, reported in Historical Archaeology, ...

For elderly, even short falls can be deadly

2010-11-02
While simple falls, such as slipping while walking off a curb, may seem relatively harmless, they can actually lead to severe injury and death in elderly individuals, according to a new study published in The Journal of Trauma: Injury, Infection, and Critical Care. As the population continues to age, it is important for physicians and caregivers to be aware of and prepared to deal with this issue, which could significantly impact the overall health and wellbeing of older adults. In contrast to falls from greater heights, ground-level falls – essentially falls from a ...

New American Chemical Society podcast: Stop wasting food and save energy

2010-11-02
WASHINGTON, Nov. 1, 2010 — Generations of Moms and Grandmas have preached the virtues of not wasting food. Now scientists are reporting a compelling new reason to follow this advice: It could save enormous amounts of energy, according to the latest episode in the American Chemical Society's (ACS) award-winning podcast series, "Global Challenges/Chemistry Solutions." They say that the United States could immediately save the energy equivalent of about 350 million barrels of oil a year — without spending a penny or putting a ding in the quality of life: Just stop wasting ...

Inhaled steroids increase diabetes risk, say Lady Davis Institute researchers

2010-11-02
Patients taking inhaled corticosteroids are at increased risk of developing type 2 diabetes, and more so with higher doses, say researchers at the Jewish General Hospital's Lady Davis Institute for Medical Research (LDI) In Montreal. The risk is of special concern for patients suffering from chronic obstructive pulmonary disorder (COPD), and much less significant for asthmatics. "These medications are very effective in asthma, so the benefits clearly outweigh the risk for asthmatics," said Dr. Samy Suissa, Director of the Centre for Clinical Epidemiology at the LDI, and ...

Common stomach bacteria may fight off inflammatory bowel disease caused by Salmonella

2010-11-02
Ann Arbor, Mich. — Helicobacter pylori, a common stomach bacterium, reduced the severity of inflammation of the colon caused by Salmonella in mice, according to research from U-M Medical School scientists. More than half the people in the world are infected with H. pylori, although it is very unusual to find it in the United States. But this research shows there may be an inflammation control benefit to hosting the H. pylori infection, says Peter Higgins, M.D., Ph.D., M.Sc., lead author of the study published last week in the journal Inflammatory Bowel Diseases. "If ...

In the job hunt, people do lie, but honesty pays off, study finds

2010-11-02
Honesty pays off, according to a new study of job seekers. When job applicants were warned that a pre-employment test could detect fake responses, they gave more honest answers -- a result that could improve their chances of being hired. Results were published in the human resources journal Applied HRM Research. "People may be tempted to make themselves look as attractive as possible to employers, but honesty is always the best policy, since many pre-employment tests have ways to spot fakers," said Chris Wright, associate professor of psychology at San Francisco State ...

The zebrafish's neural circuit prevents it from biting off more than it can chew

The zebrafishs neural circuit prevents it from biting off more than it can chew
2010-11-02
Between alerting us to danger and allowing us to spot prey, vision keeps many animals, including humans, alive. But exactly how does this important sense work, and why is it easier for us to spot movement of small objects in our field of vision, than to notice other things? The complexity of the neural network that supports vision has long baffled scientists. Now, with a new technology and support from the National Science Foundation, Claire Wyart in Ehud Isacoff's lab at the University of California at Berkeley and Filo Del Bene at Herwig Baier's lab at the University ...

2010-11-02
Boston, MA, October 30, 2010 – Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) today announced new data from its Phase 3 studies of people with genotype 1 chronic hepatitis C who have not been treated previously. In these studies, the majority of people achieved superior sustained viral response (SVR or viral cure) rates with a telaprevir-based combination regimen, compared to current therapies, regardless of race/ethnicity or stage of liver fibrosis (factors known to limit response to current hepatitis C treatments). Patients in the ADVANCE and ILLUMINATE studies were ...

Study improves accuracy of models for predicting ozone levels in urban areas

2010-11-02
A team of scientists has, for the first time, completely characterized an important chemical reaction that is critical to the formation of ground-level ozone in urban areas. The team's results indicate that computer models may be underestimating ozone levels in urban areas during episodes of poor air quality (smoggy days) by as much as five to 10 percent. Ground level ozone poses significant health hazards to people, animals and plants; is the primary ingredient of smog; and gives polluted air its characteristic odor. It is known that even small increases in ozone concentrations ...

2010-11-02
A recent scientific discovery made by researchers at the Institut de recherches cliniques de Montréal (IRCM) led by Dr. Javier Marcelo Di Noia, Director of the Mechanisms and Genetic Diversity research unit, was published online today by The Journal of Experimental Medicine. The team identified a mechanism regulating activation-induced deaminase (AID), which could be important for the therapy of some types of lymphoma and leukemia. AID is a B-lymphocyte enzyme that creates deliberate mutations in the DNA encoding antibodies, which helps produce an appropriate immune ...

Research explores lung cancer among pediatric cancer patients

2010-11-02
Because primary lung adenocarcinoma is exceedingly rare in the pediatric population, it is difficult to properly classify certain lung tumors in children and adolescents. While anecdotal reports of pediatric patients with lung cancer lesions exist, little research has been conducted to link the disease in children to similar pulmonary malignancies in adults. Through an assessment of clinical, tissue-based and molecular data for pediatric lung cancer, research published in the November edition of the Journal of Thoracic Oncology determined that pulmonary lesions found in ...

Grasses have potential as alternate ethanol crop, Illinois study finds
2010-11-02
CHAMPAIGN, Ill. — Money may not grow on trees, but energy could grow in grass. Researchers at the University of Illinois have completed the first extensive geographic yield and economic analysis of potential bioenergy grass crops in the Midwestern United States. Demand for biofuels is increasing as Americans seek to expand renewable energy sources and mitigate the effects of fluctuating energy prices. Corn ethanol is the main biofuel on the market, but demand for ethanol competes with corn's availability as a food, and rising ethanol consumption could lead to higher food ...

Of 50,000 small molecules tested to fight cancer, 2 show promise

2010-11-02
BOSTON (3:00 p.m. ET, November 1, 2010) — A class of compounds that interferes with cell signaling pathways may provide a new approach to cancer treatment, according to a study published online this week in the Proceedings of the National Academy of Sciences (PNAS) Early Edition. The compounds, called PITs (non-phosphoinositide PIP3 inhibitors), limited tumor growth in mice by inducing cell death. "PITs cause cells to self-destruct by interfering with the signaling pathways that regulate cell survival. As compounds that promote cell death, PITs show promise in halting ...

Anger makes people want things more

2010-11-02
Anger is an interesting emotion for psychologists. On the one hand, it's negative, but then it also has some of the features of positive emotions. For a new study published in Psychological Science, a journal of the Association for Psychological Science, researchers find that associating an object with anger actually makes people want the object—a kind of motivation that's normally associated with positive emotions. People usually think of anger as a negative emotion. You're not supposed to get angry. But anger also has some positive features. For example, it activates ...

New way of removing excess nitrogen from the environment

2010-11-02
Excess nitrogen from agricultural and urban lands is contaminating groundwater, streams, lakes and estuaries, where it causes harmful algal blooms and contributes to fish kills. Cost-effective approaches to removing this nitrogen from croplands and urban stormwater runoff before it reaches sensitive water bodies have been elusive. But simple and inexpensive technologies are on the horizon. A recent scientific workshop on denitrification brought together ecologists, engineers and policy experts to find answers. Denitrification is a biological process carried out by ...
