Getting more people to eat seafood because it's a healthier option will need careful planning to ensure that the expansion of the aquaculture sector does not pose a risk to the environment. Business leaders in the sector should not aim only for profits, but rather embrace the principles of the One Health model that sees the health of humans being interwoven with that of animals and the environment. The model brings together experts from various fields to develop sustainable operations that ensure adequate human nutrition, and healthy environments, say Juan Gormaz of the ...

NASA-NOAA's Suomi NPP Satellite passed over Typhoon Rammasun early on July 14 and captured a visible image of the storm that showed large bands of thunderstorms wrapping into the center as it approached the central Philippines. When NASA-NOAA's Suomi NPP satellite passed over Rammasun on July 14 at 04:20 UTC, the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard took a visible image of the storm. The VIIRS instrument showed large, thick bands of powerful thunderstorms wrapping into the low-level center of circulation. The largest band extended from the ...

Circulating tumor cells spread ovarian cancer through the bloodstream, homing in on a sheath of abdominal fatty tissue where it can grow and metastasize to other organs, scientists at The University of Texas MD Anderson Cancer Center report in Cancer Cell. "This completely new way of thinking about ovarian cancer metastasis provides new potential avenues to predict and prevent recurrence or metastasis," said senior author Anil Sood, M.D., professor of Gynecologic Oncology and Reproductive Medicine and Cancer Biology. The researchers found the circulating tumor cells ...

The once-powerful Super Typhoon Neoguri weakened to a tropical storm when it dropped heavy rainfall over southern Japan during the week of July 7, 2014. NASA and the Japan Aerospace Exploration Agency's Tropical Rainfall Measuring Mission or TRMM satellite measured that soaking from its orbit in space and data was used to create a maps showing the rainfall totals. Heavy rainfall from Neoguri fell on land that was already soaked earlier this month by a slow moving seasonal frontal system. Neoguri was reported to have caused up to five deaths and 50 injuries in Japan. Rainfall ...

Modern office workers are expected to multitask regularly, often juggling multiple projects and priorities over the course of a day. Studies have shown that the typical employee in an office environment is interrupted up to six times per hour, but how does that impact the finished product? New research published in Human Factors evaluates how ongoing interruptions can negatively affect the quality of work. "People don't realize how disruptive interruptions can be," said Cyrus Foroughi, coauthor of "Do Interruptions Affect Quality of Work?" and a PhD candidate at George ...

Analysis of clinical samples from suspected Lassa fever cases in Sierra Leone showed that about two-thirds of the patients had been exposed to other emerging diseases, and nearly nine percent tested positive for Ebola virus. The study, published in this month's edition of Emerging Infectious Diseases, demonstrates that Ebola virus has been circulating in the region since at least 2006—well before the current outbreak. First author Randal J. Schoepp, Ph.D., recently returned from Liberia and Sierra Leone, where he spent six weeks helping to set up an Ebola testing laboratory ...

WHAT: Scientists funded by the National Institutes of Health (NIH) have identified genetic markers associated with eosinophilic esophagitis (EoE), an inflammatory disease characterized by high levels of immune cells called eosinophils in the esophagus. Their findings suggest that several genes are involved in the development of EoE, which can cause difficulty eating and often is associated with food allergies. The findings also may help explain why the disease specifically affects the esophagus. The work was supported in part by the Consortium of Food Allergy Research, ...

A group of leading brain injury specialists look back on 40 years of the Glasgow Coma Scale and outline the continuing role of the scale in research and clinical practice, in a new Personal View published in The Lancet Neurology. The Personal View is published on the 40th anniversary of the Glasgow Coma Scale's introduction in a 1974 Lancet article*. Since this seminal publication, the Glasgow Coma Scale has provided a practical method for bedside assessment of impairment of conscious level, the clinical hallmark of acute brain injury. The scale was designed to be ...

Buying keywords of a popular competitors' brand names on search engines such as Google and Bing can backfire according to a new study in the Articles in Advance section of Marketing Science, a journal of the Institute for Operations Research and the Management Sciences (INFORMS). Firms buy specific keywords, including competitors' brand names, on search engines to reach consumers searching for those words. Online advertisements employing such keywords are called search ads. Sometimes a brand such as Nissan Altima will buy search ads to reach customers who conduct a ...

CORVALLIS, Ore. – New research suggests that use of antibiotics is still prevalent among terminal patients who have chosen hospice care as an end-of-life option, despite little evidence that the medications improve symptoms or quality of life, and sometimes may cause unwanted side effects. The use of antibiotics is so engrained in contemporary medicine that 21 percent of patients being discharged from hospitals directly to a hospice program leave with a prescription for antibiotics, even though more than one fourth of them don't have a documented infection during their ...

This news release is available in German. Many animals exhibit segmental patterns that manifest themselves during development. One classical example is the sequential and rhythmic formation the segmental precursors of the backbone, a process that has been linked to the ticking of an oscillator in the embryo – the "segmentation clock". Until now, this patterning process was thought to be determined simply by the time scale of genetic oscillations that periodically trigger new segment formation. However, this week in the journal Science, Max Planck researchers suggest ...

Together with the company Tissuegnostics, the pathologist Lukas Kenner and his colleagues have developed a software that is able to identify cancer cells in tissue sections and demonstrate the presence of specific biomarkers on cells. The overall information provides a precise picture of the disease and leads to the most suitable treatment. According to the results of the study, "Two independent pathologists concur with each other only in regard of every third diagnosis." "The recently developed software offers, for the first time, the option of eliminating the so-called ...

The public perception that No Child Left Behind has increased burnout and lowered job satisfaction among teachers is unfounded, according to a recent study co-authored by UT Dallas researcher Dr. James R. Harrington. The study, which was published online in Educational Evaluation and Policy Analysis, a peer-reviewed journal of the American Educational Research Association, found that, overall, the accountability pressures of No Child Left Behind (NCLB) did not have much of an impact on teachers' job satisfaction or commitment to the profession. NCLB is the latest version ...

CLEVELAND, Ohio (July 14, 2014)—In the 2,500+ years that have passed since acupuncture was first used by the ancient Chinese, it has been used to treat a number of physical, mental and emotional conditions including nausea and vomiting, stroke rehabilitation, headaches, menstrual cramps, asthma, carpal tunnel, fibromyalgia and osteoarthritis, to name just a few. Now, a meta-analysis of randomized controlled trials which is being published this month in Menopause, the journal of The North American Menopause Society (NAMS), indicates that acupuncture can affect the severity ...

In the movie "Terminator 2," the shape-shifting T-1000 robot morphs into a liquid state to squeeze through tight spaces or to repair itself when harmed. Now a phase-changing material built from wax and foam, and capable of switching between hard and soft states, could allow even low-cost robots to perform the same feat. The material — developed by Anette Hosoi, a professor of mechanical engineering and applied mathematics at MIT, and her former graduate student Nadia Cheng, alongside researchers at the Max Planck Institute for Dynamics and Self-Organization and Stony ...

A research team from the University of Illinois at Urbana-Champaign has developed a novel, tunable nanoantenna that paves the way for new kinds of plasmonic-based optomechanical systems, whereby plasmonic field enhancement can actuate mechanical motion. "Recently, there has been a lot of interest in fabricating metal-based nanotextured surfaces that are pre-programmed to alter the properties of light in a specific way after incoming light interacts with it," explained Kimani Toussaint, an associate professor of mechanical science and engineering who led the research. ...

Prof. Rivka Inzelberg of Tel Aviv University's Sackler Faculty of Medicine and the Sagol Neuroscience Center at Sheba Medical Center, Tel Hashomer, documented the exceptional creativity of Parkinson's patients two years ago in a review for Behavioral Neuroscience. Since then, she has conducted the first empirical study to verify a link between Parkinson's disease and artistic inclination. That empirical study, now published in the Annals of Neurology, definitively demonstrates that Parkinson's patients are more creative than their healthy peers, and that those patients ...

Antibiotic resistance is depleting our arsenal against deadly diseases and infections, such as tuberculosis and Staph infections, but recent research shows promise to speed up the drug discovery process. In a study reported in ACS Chemical Biology, University of Illinois researchers developed a new technique to quickly uncover novel, medically relevant products produced by bacteria. Past techniques involved screening more than 10,000 samples to find a novel product, said principal investigator Doug Mitchell, assistant professor of chemistry and Institute for Genomic ...

Is cancer an inevitable consequence of aging? Although it is widely thought that cancer is an inevitable consequence of aging, the risk of developing several common cancers decreases with age. Researchers have long been puzzled by the apparent decrease with age in the risk of developing certain adult cancers. A possible solution to this puzzle was presented in a recent paper published in Biophysical Reviews and Letters by Professor James P. Brody of the Department of Biomedical Engineering at the University of California, Irvine. "Most cancers have a characteristic ...

For the Spanish Royal Academy, senescent is he who "begins to age". But laboratory biology results are contradicting the dictionary: not only is senescence not a synonym of ageing, it is also not intrinsically negative for the organism. Cellular senescence is such a badly named physiological process that those who do research in this area think it needs another name. That is the case of Manuel Serrano, from the Spanish National Cancer Research Centre (CNIO), one of the world's leading experts on senescence, who has just published a review on this topic. Without actually ...

Washington D.C., July 14, 2014 – A recent study published in the July 2014 issue of the Journal of the American Academy of Child and Adolescent Psychiatry confirms the validity of the DSM-5 change to the age of onset criterion for diagnosis of attention-deficit/hyperactivity disorder (ADHD). In DSM-5, age of onset criterion for ADHD, previously set at 7 in DSM-IV, has been raised to 12. As explained in DSM-5, age of onset is now set at 12, rather than an earlier age, to reflect the importance of clinical presentation during childhood for accurate diagnosis, while also ...

Philadelphia, PA, July 14, 2014 – The inability to ignore irrelevant stimuli underlies the impaired working memory and cognition often experienced by individuals diagnosed with schizophrenia, reports a new study in the current issue of Biological Psychiatry. Our brains are usually good at focusing on the information that we are trying to learn and filtering out the "noise" or thoughts that aren't relevant. However, memory impairment in schizophrenia may be related in part to a problem with this filtering process, which Dr. Teal Eich at Columbia University and her colleagues ...

Superconductors are futuristic materials that will hopefully have a broad range of technological applications at some time in the future (medical imaging, transport…). Today's use is limited by the extremely low temperatures (close to absolute zero) required for superconductivity to manifest. However, some families of these materials work at "relatively" high temperatures (about - 200° C), and it's on these that scientists are focusing their attention. Among them are copper-based superconductors, which have very unique characteristics. A study conducted by researchers of ...
