Why do some chemical farmers resist a profitable conversion to organic methods? A new study in the Journal of Marketing suggests it may be because making that change feels like switching belief systems. "The ideological map of American agriculture reveals an unfolding drama between chemical and organic farming," write authors Melea Press (University of Bath), Eric Arnould (Southern Denmark University), Jeff Murray (University of Arkansas) and Katherine Strand (McGill University). "Chemical farmers argue that to make money, one must follow chemical traditions; when organic ...

As obesity rates rise, health professionals and policy makers scramble to help consumers resist unhealthy eating choices, often focusing on better labeling and improved nutritional knowledge. According to a new study in the Journal of Marketing Research, however, training people to pay attention to their emotions is a far more powerful strategy. "Consumers are often mindless," write authors Blair Kidwell (Ohio State University), Jonathan Hasford (Florida International University) and David M. Hardesty (University of Kentucky). "We not only demonstrate that emotional ...

The American obesity epidemic is out of control, and health advocates are working hard to ensure that food labels clearly list calorie content and all unhealthy ingredients. But according to a new study in the Journal of Marketing Research, labeling alone contributes little to healthier eating decisions unless the item also costs more. "Obesity rates have more than doubled in the past two decades, and large-scale interventions are necessary to dissuade people from consuming unhealthy food," write authors Avni M. Shah (Duke University), James R. Bettman (Duke University), ...

Cities around the world are pouring money into beautiful bicycle paths in hopes of convincing citizens to drive less and bike more. According to a new study in the Journal of Public Policy & Marketing, however, getting people to go from four to two wheels isn't quite that simple. "Although bicycling is a widely accepted way to travel around cities in Germany, Denmark, and the Netherlands," write authors Marius C. Claudy (University College, Dublin) and Mark Peterson (University of Wyoming), "it is still the most underutilized form of transportation in countries such as ...

Reserve's borders have erroneously moved 50 kilometers New species, named after the Luama Katanga Reserve, is now threatened by cattle ranches and forest destruction NEW YORK (November 11, 2014) - WCS scientists in the Democratic Republic of Congo (DRC) have discovered a new species of plant living in a remote rift valley escarpment that's supposed to be inside of a protected area. But an administrative mapping error puts the reserve's borders some 50 kilometers west of the actual location. Now the new species, along with 900 other plant varieties and 1,400 chimpanzees, ...

For their study, the researchers were able to fall back on uninterrupted long-term temperature measurements of groundwater flows around the cities of Cologne and Karlsruhe, where the operators of the local waterworks have been measuring the temperature of the groundwater, which is largely uninfluenced by humans, for forty years. This is unique and a rare commodity for the researchers. "For us, the data was a godsend," stresses Peter Bayer, a senior assistant at ETH Zurich's Geological Institute. Even with some intensive research, they would not have been able to find a ...

Many businesses now offer customers the opportunity to make charitable donations to good causes along with their purchases, but does this really encourage the customer to buy more? According to a new study in the Journal of Marketing, the answer is a firm "Yes." "The mere presence of a charitable donation opportunity can generate significantly more sales," write authors Michelle Andrews (Temple University), Xueming Luo (Temple University), Zheng Fang (Sichuan University) and Jaakko Aspara (Hanken Swedish School of Economics). "Offering the donation nearly doubled the ...

When consumers see a company performing good deeds, they often assume that the company's products are healthy. According to a new study in the Journal of Public Policy & Marketing this may be far from true, and the company's socially responsible behavior may be creating a "health halo" over unhealthy foods. "Research demonstrates that consumers frequently engage in inference making when evaluating food products. These inferences can be highly inaccurate, leading to unintended, unhealthy consumer choices," write authors John Peloza (University of Kentucky), Christine Ye ...

A novel method of altering a protein in milk to bind with an antiretroviral drug promises to greatly improve treatment for infants and young children suffering from HIV/AIDS, according to a researcher in Penn State's College of Agricultural Sciences. That's critical because an estimated 3.4 million children are living with HIV/AIDS, the World Health Organization reports, and nine out of 10 of them live in resource-limited countries in sub-Saharan Africa, where effective antiretroviral treatments still are not widely accessible or available. International medical experts ...

Enterotoxigenic Escherichia coli (ETEC) bacteria are responsible each year for around 400 million cases of diarrhoea and 400,000 deaths in the world's low- and middle-income countries. Children under the age of five are most affected. ETEC bacteria also cause diarrhoea in nearly one in two travellers to these areas. Major breakthrough Researchers at the University of Gothenburg's Sahlgrenska Academy are world leaders in research into ETEC and have now made a major breakthrough in collaboration with colleagues from the Wellcome Trust Sanger Institute in the UK, Karolinska ...

As football players are learning, a violent blow to the head has the potential to cause mild to severe traumatic brain injury -- physical damage to the brain that can be debilitating, even fatal. The long-term effects run the gamut of human functioning, from trouble communicating to extensive cognitive and behavioral deterioration. To date, there is no effective medical or cognitive treatment for patients with traumatic brain injuries. But a new study from Tel Aviv University researchers points to an "enriched environment" -- specially enhanced surroundings -- as a promising ...

Technology developed at the University of Sussex helps hospitals make earlier and more accurate treatment decisions and survival assessments for patients with bowel cancer. Bowel cancer kills more than 16,000 people a year in the UK, making it the nation's second-most common cause of cancer death (after lung cancer). A novel medical-imaging technology, TexRAD, which analyses the texture of tumours, has been shown in trials to enable early diagnosis of those bowel-cancer patients not responding to the standard cancer therapy better than other available tumour markers. ...

Changes to China's drink driving laws are catching the community off guard with more than 70 per cent of people unaware of the blood alcohol limits that could see them face criminal charges, according to new Queensland University of Technology (QUT) research conducted in two Chinese cities. QUT's Centre for Accident Research & Road Safety - Queensland (CARRS-Q) has partnered with organisations in China to promote road safety and reduce fatalities and injuries, as alcohol-related driving offences are being brought into sharper focus because of the country's rapid motorisation ...

A new climate change modeling tool developed by scientists at Indiana University, Princeton University and the National Oceanographic and Atmospheric Administration finds that carbon dioxide removal from the atmosphere owing to greater plant growth from rising CO2 levels will be partially offset by changes in the activity of soil microbes that derive their energy from plant root growth. Soils hold more carbon than all of the earth's plant biomass and atmosphere combined. The new work published by Benjamin N. Sulman, a postdoctoral researcher in the lab of co-author and ...

INDIANAPOLIS -- A new treatment regimen for hepatitis C, the most common cause of liver cancer and transplantation, has produced results that will transform treatment protocols for transplant patients, according to research published online today in the New England Journal of Medicine. The investigational three-drug regimen, which produced hepatitis C cure rates of 97 percent, is an oral interferon-free therapy. Previously, the typical treatment for hepatitis C after a liver transplant was an interferon-based therapy, usually given for 48 weeks. It had a much lower response ...

Lead researcher, Dr Sarah Dunstan from the Nossal Institute of Global Health at the University of Melbourne said the study is the first large-scale, unbiased search for human genes that affect a person's risk of typhoid. Enteric fever, or typhoid fever as it more commonly known, is a considerable health burden to lower-income countries. This finding is important because this natural resistance represents one of the largest human gene effects on an infectious disease. "We screened the human genome to look for genes associated with susceptibility to, or resistance ...

Weeds in the UK are still evolving hundreds of years after their introduction and are unlikely to have yet reached their full potential as invaders, UNSW Australia scientists have discovered. The study is the first to have tracked the physical evolution of introduced plant species from the beginning of their invasion to the present day, and was made possible by the centuries-old British tradition of storing plant specimens in herbaria. The research team, led by Habacuc Flores-Moreno, looked at three common weeds - Oxford ragwort, winter speedwell and a willow herb - which ...

A controversial medication used by breastfeeding women should not be restricted because of the benefits it offers mothers and their babies, according to researchers at the University of Adelaide. The medication domperidone has recently been the subject of warnings from the European Medicines Agency based on research that there is a link between the medication and fatal heart conditions. Domperidone has been banned in the United States for years because of fatal cardiac arrhythmias among cancer patients who had been prescribed the drug to prevent nausea and vomiting. However, ...

This news release is available in German. X-rays are widely used in medicine and in materials science. To take a picture of a broken bone, it is enough to create a continuous flux of X-ray photons, but in order to study time-dependent phenomena on very short timescales, short X-ray pulses are required. One possibility to create short hard X-ray pulses is hitting a metal target with laser pulses. The laser rips electrons out of the atoms and makes them emit X-ray radiation. Electrical engineers at the Vienna University of Technology (TU Wien) together with researchers ...

With the help of mouse models, induced pluripotent stem cells (iPSCs) and the "tooth fairy," researchers at the University of California, San Diego School of Medicine have implicated a new gene in idiopathic or non-syndromic autism. The gene is associated with Rett syndrome, a syndromic form of autism, suggesting that different types of autism spectrum disorder (ASD) may share similar molecular pathways. The findings are published in the Nov. 11, 2014 online issue of Molecular Psychiatry. "I see this research as an example of what can be done for cases of non-syndromic ...

An inter­na­tional research team led by Dan Distel, director of the Ocean Genome Legacy Center of New Eng­land Bio­labs at North­eastern Uni­ver­sity, has dis­cov­ered a novel diges­tive strategy in ship­worms. The break­through, the researchers say, may also be a game-​​changer for the indus­trial pro­duc­tion of clean biofuels. To start, it's impor­tant to note that ship­worms, the so-​​called "ter­mites of the sea," aren't actu­ally worms--they're bizarre clams that ...

WASHINGTON - Hospital workers who deal directly with patients wash their hands less frequently as their workday progresses, probably because the demands of the job deplete the mental reserves they need to follow rules, according to new research published by the American Psychological Association. Researchers led by Hengchen Dai, a PhD candidate at the University of Pennsylvania, looked at three years of hand-washing data from 4,157 caregivers in 35 U.S. hospitals. They found that "hand-washing compliance rates" dropped by an average of 8.7 percentage points from the beginning ...

The Assyrian Empire once dominated the ancient Near East. At the start of the 7th century BC, it was a mighty military machine and the largest empire the Old World had yet seen. But then, before the century was out, it had collapsed. Why? An international study now offers two new factors as possible contributors to the empire's sudden demise - overpopulation and drought. Adam Schneider of the University of California, San Diego and Selim Adalı of Koç University in Istanbul, Turkey, have just published evidence for their novel claim. "As far as we know, ...

Results of a federally-funded pooled analysis of five prospective cohort studies indicate that cigarette smoking prior to the first diagnosis of lung (stage I), bladder, kidney or head and neck cancer increases risk of developing a second smoking-associated cancer. This is the largest study to date exploring risk of second cancers among current smokers. An analysis of five large, prospective cohort studies indicates that lung (stage I), bladder, kidney and head and neck cancer survivors who smoked 20 or more cigarettes a day prior to their cancer diagnoses have an up ...

Nestled among a triplet of young galaxies more than 12.5 billion light-years away is a cosmic powerhouse: a galaxy that is producing stars nearly 1,000 times faster than our own Milky Way. This energetic starburst galaxy, known as AzTEC-3, together with its gang of calmer galaxies may represent the best evidence yet that large galaxies grow from the merger of smaller ones in the early Universe, a process known as hierarchical merging. An international team of astronomers observed these remarkable objects with the Atacama Large Millimeter/submillimeter Array (ALMA). "The ...
