ROCHESTER, Minn. — The benefits of medical imaging far outweigh the risks when children receive The Right Exam, ordered The Right Way, with The Right Radiation Dose. However, overuse and misuse of imaging change the benefit-risk ratio and Mayo Clinic is leading a collaborative effort to ensure a national protocol is put into action. The commentary, published online in the Journal of Patient Safety, calls for the American College of Radiology, the Joint Commission, the Intersociety Accreditation Commission, and the Centers for Medicare & Medicaid Services to require three ...

NOAA's Geostationary Operational Environmental Satellite or GOES-West satellite spotted smoke over the U.S. Mid-West from dozens of fires raging in Canada's Northwestern Territories. At 1200 UTC (8 a.m. EDT) on July 9, 2014, GOES-West captured this image of the brownish-colored haze created by forest fires in Canada's Northwest Territories that drifted all the way into South Dakota. This image was created by the NASA GOES Project at NASA Goddard Space Flight Center, Greenbelt, Md. According to Canada's Natural Resources, Canadian Wildland Fire Information System, fire ...

Once a powerful super typhoon, now an weakening tropical storm, NASA's Terra satellite saw a much weaker Tropical Storm Neoguri moving along the southern coast of Japan. On July 10 at 0:35 UTC, the Moderate Resolution Imaging Spectroradometer (MODIS) instrument aboard NASA's Terra satellite captured an image of a more disorganized Tropical Storm Neoguri over east central Japan. At the time of the image, a more elongated Tropical Storm Neoguri's center was east of Kyushu, Japan. A visible image from the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard ...

Defining what makes a star "Sun-like" is as difficult as defining what makes a planet "Earth-like." A solar twin should have a temperature, mass, and spectral type similar to our Sun. We also would expect it to be about 4.5 billion years old. However, it is notoriously difficult to measure a star's age so astronomers usually ignore age when deciding if a star counts as "Sun-like." A new technique for measuring the age of a star using its spin - gyrochronology - is coming into its own. Today astronomers are presenting the gyrochronological ages of 22 Sun-like stars. Before ...

Estonian-born Katerina Alba's research at the University of Huddersfield could help to improve the quality of some of the most popular emulsion-based food products – such as butter, mayonnaise, yoghurt and fruit drinks – and she is starting to gain an international profile for her work. Katerina gained her MSc degree in nutrition and food science at the University and now she has embarked on research for a PhD. Working with her supervisor, Dr Vassilis Kontogiorgos, she is investigating the potential of carbohydrates extracted from the pods of the okra plant. They can ...

EVANSTON, Ill. --- Why does a relentless stream of subjective experiences normally fill your mind? Maybe that's just one of those mysteries that will always elude us. Yet, research from Northwestern University suggests that consciousness lies well within the realm of scientific inquiry -- as impossible as that may currently seem. Although scientists have yet to agree on an objective measure to index consciousness, progress has been made with this agenda in several labs around the world. "The debate about the neural basis of consciousness rages because there is no widely ...

Many studies have shown that more severe illness and even death are likely to result if you develop a secondary respiratory infection after developing influenza. Now, however, a team of researchers based at The Wistar Institute has determined that if you reverse the order of infection, the bacteria Streptococcus pneumoniae (often called pneumococcus) may actually protect against a bad case of the flu. The researchers discovered that the bacterial protein pneumolysin, which is described as a bacterial virulence factor, might protect macrophages—a type of immune system ...

(July 10, 2014) – A research review identifying the clinical indicators most strongly associated with concussion is an important first step in the process of developing evidence-based guidelines for concussion diagnosis, prognosis, and treatment, according to a new report published by Neurosurgery, official journal of the Congress of Neurological Surgeons. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health. Based on analysis of the best available research data, a multidisciplinary panel of experts has identified a set of four ...

July 10,2014 – For children and teens living with a cardiac pacemaker, a low sense of self-competence seems to contribute to decreased quality of life, reports a study in the July Journal of Developmental & Behavioral Pediatrics, the official journal of the Society for Developmental and Behavioral Pediatrics. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health. "Self-competence may function as a protective factor against lower health-related quality of life in children with pacemakers," according to the study by Ana M. Gutierrez-Colina ...

The Universe is filled with objects springing to life, evolving and dying explosive deaths. This new image from the NASA/ESA Hubble Space Telescope captures a snapshot of some of this cosmic movement. Embedded within the egg-shaped blue ring at the centre of the frame are two galaxies. These galaxies have been found to be merging into one and a "chain" of young stellar superclusters are seen winding around the galaxies' nuclei. At the centre of this image lie two elliptical galaxies, part of a galaxy cluster known as[HGO2008]SDSS J1531+3414, which have strayed into each ...

Stars forming like a string of blue pearls along two elliptical galaxies could be the result of a galactic merger, according to an international team of astronomers. The structure could reveal rare insights about elliptical galaxies. Scientists from Rochester Institute of Technology helped analyze data from the Hubble Space Telescope showing elliptical galaxies coalescing at the core of a dense galaxy cluster. The study is part of a program sponsored by the Hubble Space Telescope—an international cooperation between NASA and the European Space Agency—to look inside 23 ...

EAST LANSING, Mich. – For those students looking to bump up their grade point averages during college, the answer may not be spending more time in a library or study hall, but in a gym. New Michigan State University research shows that students who were members of the recreational sports and fitness centers on MSU's campus during their freshman and sophomore years had higher GPAs than those who weren't. The research also indicated that students with memberships stayed in school longer. An increase of 3.5 percent in two-year retention rates was seen among this group. "That ...

Mathematical algorithms used to control everyday household items such as washing machines could hold the key to winning the fight for conservation, a new study has claimed. As part of an EPSRC research project, a team of UK scientists and mathematicians, including those from the University of Exeter, have shown how techniques commonly used in control engineering, could be replicated in the natural world to help restock declining populations. The innovative new study suggests 'integral control' - in essence a built-in feedback control mechanism to maintain a constant – ...

This natural-color satellite image was collected by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Aqua satellite on July 10, 2014. Each hot spot, which appears as a red mark, is an area where the thermal detectors on the MODIS instrument recognized temperatures higher than background. When accompanied by plumes of smoke, as in this image, such hot spots are diagnostic for fire. This area of Russia is extremely remote with little danger coming directly from the fires, although the smoke released by any type of fire (forest, brush, crop, structure, ...

Diluted magnetic semiconductors (DMS) have received much attention due to their potential application in spintronics, or the storage and transfer of information by using an electron's spin state, its magnetic moment and its charge. In typical systems based on III-V semiconductors, such as (Ga,Mn)As, (In,Mn)As or (Ga,Mn)N, substitution of divalent Mn atoms into trivalent Ga (or In) sites leads to severely limited chemical solubility, resulting in metastable specimens only available as epitaxial thin films. The hetero-valence substitution, which simultaneously dopes both ...

Scientists at The University of Manchester are a step closer to understanding why diabetes is cured in the majority of patients that undergo gastric bypass surgery. The research, published in the journal Endocrinology, shows the cure is likely to be explained by the actions of specialised cells in the intestine that secrete a cocktail of powerful hormones when we eat. During the research, the team showed that gut hormone cells previously thought to contain just one hormone, had up to six hormones including the hunger hormone ghrelin. Study team leader, Dr Craig ...

ANN ARBOR – Because the strong currents in the Straits of Mackinac reverse direction every few days, a rupture of the oil pipeline beneath the channel would quickly contaminate shorelines miles away in both lakes Michigan and Huron, according to a new University of Michigan study commissioned by the National Wildlife Federation. In one scenario examined in the study and accompanying animations, oil from a hypothetical pipeline break reached Mackinac Island and Round Island after 12 hours and Bois Blanc Island after two days. All three islands are in westernmost Lake Huron, ...

Manchester scientists have shown that a new drug could prove useful in treating small cell lung cancer - the most aggressive form of lung cancer. Scientists from the Cancer Research UK Manchester Institute, based at The University of Manchester and part of the Manchester Cancer Research Centre, teamed up with experts at AstraZeneca, as part of a collaboration agreed in 2010, to test a drug – known as AZD3965 - on small cell lung cancer cells. The research, published in the journal Clinical Cancer Research, also helps identify which patients are most likely to respond ...

Researchers at sarcomas research group at the Bellvitge Biomedical Research Institute (IDIBELL) and the Catalan Institute of Oncology (ICO) have been tested in 19 patients a new therapeutic combination to combat resistant sarcomas. The clinical trial results, which indicate that the new treatment could stabilize the growth of these tumors have been published this week in the British Journal of Cancer. Sarcomas Sarcomas are a rare type of tumor and complex since there are several subtypes. It can affect from children to older ages. It is usually diagnosed in advanced and ...

PROVIDENCE, R.I. [Brown University] — To keep data safe in the cloud, a group of computer scientists suggests doing the Melbourne Shuffle. That may sound like a dance move (and it is), but it's also a computer algorithm developed by researchers at Brown University. The computing version of the Melbourne Shuffle aims to hide patterns that may emerge as users access data on cloud servers. Patterns of access could provide important information about a dataset — information that users don't necessarily want others to know — even if the data files themselves are encrypted. "Encrypting ...

WASHINGTON - Cigarette warning labels can influence a smoker to try to quit even when the smoker is trying to avoid seeing the labels, according to a survey of thousands of adult smokers in four countries published by the American Psychological Association. Small, text-only warning labels like those on cigarette packs in the United States prompt people to think about health risks of smoking, and people who notice the warnings regularly are more likely to try to quit, the research found. Larger, more graphic warning labels like those in other countries, such as Australia, ...

The discovery of a split-second burst of radio waves by scientists using the Arecibo radio telescope in Puerto Rico provides important new evidence of mysterious pulses that appear to come from deep in outer space. The finding by an international team of astronomers, published July 10 in The Astrophysical Journal, marks the first time that a so-called "fast radio burst" has been detected using an instrument other than the Parkes radio telescope in Australia. Scientists using the Parkes Observatory have recorded a handful of such events, but the lack of any similar findings ...

A neuroscientist at Rutgers University-Newark says the human brain operates much the same whether active or at rest – a finding that could provide a better understanding of schizophrenia, bipolar disorder and other serious mental health conditions that afflict an estimated 13.6 million Americans. In newly published research in the journal Neuron, Michael Cole, an assistant professor at the Center for Molecular and Behavioral Neuroscience, determined that the underlying brain architecture of a person at rest is basically the same as that of a person performing a variety ...

Cold Spring Harbor, NY – For decades, health-conscious people around the globe have taken antioxidant supplements and eaten foods rich in antioxidants, figuring this was one of the paths to good health and a long life. Yet clinical trials of antioxidant supplements have repeatedly dashed the hopes of consumers who take them hoping to reduce their cancer risk. Virtually all such trials have failed to show any protective effect against cancer. In fact, in several trials antioxidant supplementation has been linked with increased rates of certain cancers. In one trial, ...

Depressed men with localized prostate cancer were more likely to be diagnosed with more aggressive prostate cancer, received less effective treatments and survived for shorter times than prostate cancer patients who were not depressed, a UCLA study has found. The negative outcomes may be the result of several factors such as bias against the mentally ill, depression's impact on biological cancer processes, the depressed man's lack of investment in his general health and disinterest in receiving more effective care, and missed opportunities by physicians to educate patients ...
