The work, that proposes a new methodology to assess the degree of air traffic congestion, is published on the latest issue of Scientific Reports. The study, based on data collected by the Federal Aviation Administration of the United States, provides a tool to evaluate airlines planning and confirms that ...

Researchers at USC have developed a new lithium-ion battery design that uses porous silicon nanoparticles in place of the traditional graphite anodes to provide superior performance. The new batteries—which could be used in anything from cell phones to hybrid cars—hold three times as much energy as comparable graphite-based designs and recharge within 10 minutes. The design, currently under a provisional patent, could be commercially available within two to three years. "It's an exciting research. It opens the door for the design of the next generation lithium-ion batteries," ...

Researchers have developed a model that will, hopefully, help companies develop innovative products that people actually want to use. The model is a first step towards capturing the behavior of both companies and consumers, so that we end up with more iPods and fewer Edsels. This concept may sound obvious, but companies have difficulty grasping it. Companies constantly try to develop new products and services that capture market share. We knew that. Consumers constantly try to evaluate recent innovations to determine whether they're useful, and how much they'd be willing ...

New Rochelle, NY, February 12, 2013—About 1 in 150 children are affected by an autism spectrum disorder (ASD), a group of neurodevelopmental disorders characterized by difficulty with language, communication, and social interaction. A critical review of several published studies evaluating the potential for therapy or assistance dogs to help children with ASD overcome some of these challenges is published in The Journal of Alternative and Complementary Medicine, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers.

Irvine, Calif., Feb. 12, 2013 – Already strained by water scarcity and political tensions, the arid Middle East along the Tigris and Euphrates rivers is losing critical water reserves at a rapid pace, from Turkey upstream to Syria, Iran and Iraq below. Unable to conduct measurements on the ground in the politically unstable region, UC Irvine scientists and colleagues used data from space to uncover the extent of the problem. They took measurements from NASA's Gravity Recovery and Climate Experiment satellites, and found that between 2003 and 2010, the four nations lost ...

Troy, N.Y. – A new study from engineers at Rensselaer Polytechnic Institute and the University of California, Berkeley, pairs light and genetics to give researchers a powerful new tool for manipulating cells. Results of the study, published in the journal Nature Methods, show how blue light can be used as a switch to prompt targeted proteins to accumulate into large clusters. This process of clustering, or oligomerization, is commonly employed by nature to turn on or turn off specific signaling pathways used in cells' complex system of communications. The new study details ...

More and more opioids are being prescribed for pain relief in Germany. This is the conclusion arrived at by Ingrid Schubert, Peter Ihle, and Rainer Sabatowski, whose study of a sample of inhabitants of the state of Hesse with health insurance from a large statutory provider is published in the latest issue of Deutsches Ärzteblatt International (Dtsch Arztebl Int 2013; 110(4): 45-51). Behind this study lies the intention to improve pain treatment with opioids, particularly for patients with cancer. Prescribing too little results in inadequate alleviation of pain, while ...

SHREWSBURY, MA -- A study published today in the Journal of Applied Physiology, Nutrition, and Metabolism presented compelling data showing the consumption of both high fructose corn syrup (HFCS) and sucrose (table sugar) at levels consistent with average daily consumption do not increase liver fat in humans, a leading cause of non-alcoholic fatty liver disease (NAFLD). The findings also add to an already well-established body of science that high fructose corn syrup and table sugar are metabolically equivalent. Increased fat levels in the liver and muscle tissue have ...

When is it time for parents to back away? A new study shows that college students with overcontrolling parents are more likely to be depressed and less satisfied with their lives. This so-called helicopter parenting style negatively affects students' well-being by violating their need to feel both autonomous and competent. The work, by Holly Schiffrin and colleagues from the University of Mary Washington in the United States, is published online in Springer's Journal of Child and Family Studies. Parental overinvolvement may lead to negative outcomes in children, including ...

JACKSONVILLE, Fla. — Researchers at Mayo Clinic have discovered an abnormal protein that accumulates in the brains of many patients affected with two common neurodegenerative disorders — amyotrophic lateral sclerosis, also known as ALS or Lou Gehrig's disease, and frontotemporal dementia. They say their findings have uncovered a potentially new therapeutic target and biomarker that would allow clinicians to confirm diagnosis of the diseases. The study is published online today in the journal Neuron. The Mayo research team, led by scientists at Mayo Clinic's campus in ...

Conservatives and liberals don't just differ when it comes to politics, they may also make different purchases at the grocery store, according to new research published in Psychological Science, a journal of the Association for Psychological Science. Psychological research has shown that conservatives and liberals differ on basic personality traits such as conscientiousness, tolerance for uncertainty, and openness to new experience. Researcher Vishal Singh of New York University Stern School of Business and colleagues hypothesized that the conservative tendency to prefer ...

COLUMBIA, Mo. – Health care transition (HCT) services help young people with special health care needs such as asthma or diabetes move from pediatric to adult health care. However, youths with autism spectrum disorder (ASD) have less access to these services, which are designed to prevent gaps in care and insurance coverage. A University of Missouri researcher recommends that the medical community develop HCT services for individuals with ASD as a way to ensure consistent and coordinated care and increase their independence and quality of life. Nancy Cheak-Zamora, an ...

A large-scale field experiment conducted during the December 2011 parliamentary elections in Russia suggests that fraud had a significant impact on the results. The research marks an advance in efforts to quantify vote fraud. The researchers, including a visiting research scholar at Princeton University, estimate that fraud accounted for at least 11 percentage points of the vote recorded for the ruling United Russia party in Moscow. They estimated that the party received at least 635,000 votes in the city as a result of fraud in the election, which resulted in United ...

Territorial song sparrows use increasingly threatening signals to ward off trespassing rivals. First an early warning that matches the intruder's song, then wing waving – a bird's version of "flipping the bird" – as the dispute heats up, and finally, if all other signals have failed, attack. This hierarchical warning scheme, discovered by researchers at the University of Washington, adds nuance to a communication system that has been long-used as a model to study how people use and learn language "This is one of the most complicated communication systems outside of ...

An analysis of policy documents from Medicaid programs, suggests that current policies to manage conflicts of interest (COIs) of members of Medicaid drug selection committees are not transparent and vary widely, according to a report published Online First by JAMA Internal Medicine, a JAMA Network publication. It is important to manage COI for formulary drug selections or reimbursement to ensure that products are selected based on evidence and with minimal bias and to protect against pharmaceutical industry influence, according to the study background. In an analysis, ...

Stage at diagnosis only partly explains the wide variation in lung cancer survival rates among different developed countries, indicates a large study of nearly 60,000 patients, published online in Thorax. Other factors, such as treatment, are also likely to have a key role, say the authors. Stage at diagnosis has often been suggested as one of the primary reasons why lung cancer survival is low in certain countries, such the UK, on the grounds that patients go to see their doctors too late for treatment to be effective. The authors collected information on more ...

The number of children admitted to hospital as emergencies has steadily increased every year since 2003, with the largest rises seen among the under 5s, indicates research published online in the Archives of Disease in Childhood. Common infections account for much of this rise, say the authors, who suggest this indicates a "systematic failure in the NHS" to assess children with acute illness that could be better managed by family doctors, out of hours services, and the telephone advice service NHS Direct rather than hospitals. The authors base their findings on hospital ...

During the 1930s, dedicated sanitaria and invasive surgery were commonly prescribed for those with the infection - usually caused by Mycobacterium tuberculosis, which the editors describe as "the most successful human pathogen of all time." TB often lies dormant with no symptoms, but in a proportion of cases, becomes active, predominantly attacking the lungs. But it can also affect the bones and nervous system, and if left untreated can be fatal. The infection is developing increasing resistance around the world to the powerful drugs currently used to treat it. "Whatever ...

University of British Columbia and Berkeley researchers have used a sophisticated new computer system to quickly reconstruct protolanguages – the rudimentary ancient tongues from which modern languages evolved. The results, which are 85 per cent accurate when compared to the painstaking manual reconstructions performed by linguists, will be published next week in the Proceedings of the National Academy of Sciences. "We're hopeful our tool will revolutionize historical linguistics much the same way that statistical analysis and computer power revolutionized the study ...

EAST LANSING, Mich. — The increasing production and use of antibiotics, about half of which is used in animal production, is mirrored by the growing number of antibiotic resistance genes, or ARGs, effectively reducing antibiotics' ability to fend off diseases – in animals and humans. A study in the current issue of the Proceedings of the National Academy of Sciences shows that China – the world's largest producer and consumer of antibiotics – and many other countries don't monitor the powerful medicine's usage or impact on the environment. On Chinese commercial pig ...
