Philadelphia, PA, March 9, 2012 – Imaging has been identified as one of the key drivers of increased healthcare costs. A new study from Brigham and Women's Hospital and Harvard Medical School has found significant variation in the use of head computed tomography (CT), even within a single emergency department. Strategies to reduce such variation in head CT use may reduce cost and improve quality of care. The study appears online in advance of publication in the April issue of The American Journal of Medicine. A recent measure approved by the Centers for Medicare and ...

Coral reefs are among the ecosystems most severely threatened by global warming, but hopeful new evidence has emerged that some coral species may be able to adapt to warmer oceans. In a study published in the journal PLoS One, an international team of researchers reports that coral populations which unexpectedly survived a massive bleaching event in 2010 in South-East Asian waters had previously experienced severe bleaching during an event in 1998. The team analysed what happened at three sites during the 2010 event and found that in Indonesia, corals responded to higher ...

One only has to be reminded of the BSE crisis and the MMR vaccine scare to recognise the importance of having policy informed by the best available science. Now, a collaboration of over fifty academics and policy makers from around the world have come together to agree a new research agenda on the role of science in public policy. The findings appear today Friday, 09 March in PLoS ONE, a leading interdisciplinary open-access journal. The importance of using science for public policy has long been recognised, but recent years have seen a growing debate over how this is ...

LONDON – (March 8, 2012) -- Ecotourism activities that use food to attract and concentrate wildlife for viewing have become a controversial topic in ecological studies. This debate is best exemplified by the shark dive tourism industry, a highly lucrative and booming global market. Use of chum or food to attract big sharks to areas where divers can view the dwindling populations of these animals has generated significant criticism because of the potential for ecological and behavioral impacts to the species. However, the debate has been largely rhetorical due to a lack ...

Washington, DC – A new linguistic study of how individuals interpret various types of utterances sheds more light on how literal and contextual meaning are distinguished. The study, "A novel empirical paradigm for distinguishing between What is Said and What is Implicated," to be published in the March 2012 issue of the scholarly journal Language, is authored by Ryan Doran, Gregory Ward, Meredith Larson, Yaron McNabb, and Rachel E. Baker, a team of linguists based at Northwestern University. A preprint version is available online at: http://lsadc.org/info/documents/2012/press-releases/doran-et-al.pdf Within ...

A recent summit that brought together international multidisciplinary experts has provided a foundation for addressing what is the leading cause of disability in the United States: osteoarthritis. Currently, validated pharmacologic interventions do not exist for effectively eliminating pain and restoring function during progression of osteoarthritis, a disease whose prevalence is expected to dramatically rise within the next decade and inflict a huge economic impact on society. The summit, which was hosted by Hospital for Special Surgery in New York City, is a first ...

If you've been thinking our world is more green than frozen these days, you're right. A recent study has found that spring is indeed arriving earlier – and autumn later – in the suburbs of Baltimore and Washington, D.C. The reason? The urban landscape traps heat in the summer and holds it throughout the winter, triggering leaves to turn green earlier in the spring and to stay green later into autumn. The result is a new, extended growing season. Scientists used high-resolution satellite data collected over the past 25 years to look at the number days that trees have green ...

LOS ANGELES (March 9, 2012) – Rowan T. Chlebowski, M.D., Ph.D., an LA BioMed investigator whose research activities have focused on breast cancer therapy and prevention, and chronic diseases impacting women's health, is co-author of a study that indicates that women who use the estrogen-only form of menopausal hormone therapy appear less likely to develop breast cancer in the longer term, according to new research which was recently published The Lancet Oncology. A follow-up study of over 7,500 women from the Women's Health Initiative (WHI) trial who took estrogen for ...

Researchers in New Zealand have developed a prototype Bluetooth-enabled medical monitoring device that can be connected wirelessly to your smart phone and keep track of various physiological parameters, such as body temperature, heart rate, blood pressure and movements. The prototype could be extended to include sensors for other factors such as blood glucose as well as markers for specific diseases. The connectivity would allow patients to send data directly to their healthcare provider and receive timely advice and medication suggestions. Writing in the International ...

Detergents are everywhere – in washing powders, dishwashing liquids, household cleaners, skin creams, shower gels, and shampoos. It is the detergent that loosens dirt and fat, makes hair-washing products foam up and allows creams to be absorbed quickly. Up until now, most detergents are manufactured from crude oil – a fossil fuel of which there is only a limited supply. In their search for alternatives, producers are turning increasingly to detergents made from sustainable resources, albeit that these surfactants are usually chemically produced. The problem is that the ...

WASHINGTON -- The U.S. Coast Guard Cutter HEALY (WAGB 20) successfully experimented with NRL's TacSat-4 communications satellite, Jan. 24, by communicating from the Bering Sea off the western coast of Alaska to Coast Guard Island, Alameda, Calif. Returning from an escort and icebreaking mission to Nome, Alaska, assisting the Russian tanker Renda delivery of emergency fuel to the town, USCGC HEALY — Coast Guard's only polar icebreaker — was approximately 260 nautical miles south of the Arctic Circle at the time of the test. Deployed into a unique, highly elliptical ...

The first global high-resolution map of the boundary between Earth's crust and mantle – the Moho – has been produced based on data from ESA's GOCE gravity satellite. Understanding the Moho will offer new clues into the dynamics of Earth's interior. Earth's crust is the outermost solid shell of our planet. Even though it makes up less than 1% of the volume of the planet, the crust is exceptionally important not just because we live on it, but because is the place where all our geological resources like natural gas, oil and minerals come from. The crust and upper mantle ...

Creating some of life's building blocks in space may be a bit like making a sandwich – you can make them cold or hot, according to new NASA research. This evidence that there is more than one way to make crucial components of life increases the likelihood that life emerged elsewhere in the Universe, according to the research team, and gives support to the theory that a "kit" of ready-made parts created in space and delivered to Earth by impacts from meteorites and comets assisted the origin of life. In the study, scientists with the Astrobiology Analytical Laboratory ...

Washington, DC, March 9, 2012 -- Hospitals whose infection prevention and control programs are led by a director who is board certified in infection prevention and control have significantly lower rates of methicillin-resistant Staphylococcus aureus (MRSA) bloodstream infections (BSI) than those that are not led by a certified professional, according to a new study published in the March issue of the American Journal of Infection Control, the official publication of APIC - the Association for Professionals in Infection Control and Epidemiology. A team of researchers ...

Desert ants have adapted to a life in a barren environment which only provides very few landmarks for orientation. Apart from visual cues and odors the ants use the polarized sunlight as a compass and count their steps in order to return safely to their home after searching for food. In experiments with ants of the genus Cataglyphis in their natural habitats in Tunisia and Turkey, behavioral scientists of the Max Planck Institute for Chemical Ecology in Jena, Germany, have now discovered that ants can also use magnetic and vibrational landmarks in order to find their way ...

Christian Santangelo, Ryan Hayward and colleagues at the University of Massachusetts Amherst recently employed photographic techniques and polymer science to develop a new technique for printing two-dimensional sheets of polymers that can fold into three-dimensional shapes when water is added. The technique may lead to wide ranging practical applications from medicine to robotics The journal Science publishes the research in its March 9 issue. Researchers used a photomask and ultraviolet (UV) light to "print" a pattern onto a sheet of polymers, a technique called photolithography. ...

Researchers have identified a genetic signature for a severe, often painful food allergy – eosinophilic esophagitis – that could lead to improved diagnosis and treatment for children unable to eat a wide variety of foods. The scientists, from Cincinnati Children's Hospital Medical Center, report in the Journal of Allergy and Clinical Immunology that they have pinpointed a dysregulated microRNA signature for eosinophilic esophagitis (EoE), a disease that also may cause weight loss, vomiting, heartburn and swallowing difficulties. Interestingly, the dysregulated microRNA ...

The faster a clock ticks, the more precise it can be. Due to the fact that lightwaves vibrate faster than microwaves, optical clocks can be more precise than the caesium atomic clocks which presently determine time. The Physikalisch-Technische Bundesanstalt (PTB) is even working on several of such optical clocks simultaneously. The model with one single ytterbium ion caught in an ion trap is now experiencing another increase in accuracy. At PTB, scientists have succeeded in exciting a quantum-mechanically strongly "forbidden" transition of this ion and – in particular – ...

The detailed feather pattern and color of Microraptor--a pigeon-sized, four-winged dinosaur that lived about 120 million years ago--had a glossy iridescent sheen. Its tail was narrow and adorned with a pair of streamer feathers, suggesting the importance of display in the early evolution of feathers, say scientists reporting the findings in this week's issue of the journal Science. By comparing the patterns of pigment-containing organelles from a Microraptor fossil to those in modern birds, the scientists determined that the dinosaur's plumage was iridescent with a ...

Infants and toddlers who have been treated for cancer tend to reach certain developmental milestones later than do their healthy peers, say researchers at the National Institutes of Health and in Italy. The findings show that delays may occur early in the course of treatment and suggest that young children with cancer might benefit from such early interventions as physical or language therapy. Compared to children who had not had cancer, children treated for cancer before age 4 progressed more slowly in vocabulary, cognitive functions such as attention and memory, and ...

Amsterdam, NL, 9 March 2012 – The number of people with neurological and psychiatric disorders in Spanish-speaking countries has increased over the past two decades. The February issue of NeuroRehabilitation assesses important factors that should be considered in rehabilitating Spanish-speaking individuals suffering from these disorders. "Though much work has been done in this area for Anglo-Saxon populations, very little work has focused on Spanish-speaking individuals," says Guest Editor Juan Carlos Arango-Lasprilla, PhD, of the Department of Physical Medicine and ...

How do we recognize a face? To date, most research has answered "holistically": We look at all the features—eyes, nose, mouth—simultaneously and, perceiving the relationships among them, gain an advantage over taking in each feature individually. Now a new study overturns this theory. The researchers—Jason M. Gold and Patrick J. Mundy of the Indiana University and Bosco S. Tjan of the University of California Los Angeles—found that people's performance in recognizing a whole face is no better than their performance with each individual feature shown alone. "Surprisingly, ...

An international team of physicists has determined a key parameter, which governs how neutrinos behave. This discovery measures a critical linchpin in the study of the tiny particles and in advancing the understanding of how these building blocks of all things, from galaxies to tea cups, came to be. The Daya Bay Reactor Neutrino Experiment, a multinational collaboration including a team from Virginia Tech, discovered a new type of neutrino oscillation in which the particles appear to vanish as they travel. The researchers found that the rate of oscillations was much larger ...
