Many Europeans are fretting these days over what they eat, and whether horse meat might have adulterated their pork chops. Food fraud has been dominating headlines globally - calling for new policies in law enforcement and more robust methods for successful food identification and authentication. As companies and manufacturers resort to fraudulent practices to extract more cash from the gullible public, it is estimated that up to 7% of the consumer supply chain contains hidden ingredients (i.e. – not disclosed on the label). And while all too often policymakers seem oblivious ...

These findings are the result of a new study carried out at the Norwegian Institute of Public Health. In the study, women who took folic acid supplements from four weeks before conception to eight weeks into pregnancy had a 40 per cent lower risk of giving birth to children with childhood autism (classic autism). "It appears that the crucial time interval is from four weeks before conception to eight weeks into pregnancy," states Pål Surén, MD and doctoral fellow at the Norwegian Institute of Public Health. The study is based on the Norwegian Mother and Child Cohort ...

Peer support groups show promise for combating the debilitating stigma that surrounds epilepsy in much of the developing world, according to a new study led by a Michigan State University medical student. The researchers report in the journal Epilepsy and Behavior that young people with the disease felt significantly less stigmatized after meeting regularly to discuss their illness. While drugs are widely available to reduce epileptic seizures, the stigma and discrimination that arise from those seizures is a thornier problem, said Melissa Elafros, who is pursuing medical ...

DURHAM, NC – Women with atrial fibrilation have more symptoms and lower quality of life than men with the same heart condition, according to an analysis of patients in a large national registry compiled by the Duke Clinical Research Institute. The finding adds to a growing body of research that highlights gender disparities in how cardiovascular disease is managed, and serves as a caution to doctors to be alert to treatment decisions that might perpetuate the differences. "We need to pay close attention to women with atrial fibrillation, and it's important for physicians ...

COLUMBUS, Ohio – A new study suggests that people get frustrated when they are offered the opportunity to cheat or steal and that chance is then taken away from them. Other studies have shown that blocking people from achieving their positive goals increases frustration, which is not surprising. But this is the first to show that even denying people the chance to commit forbidden behaviors can increase frustration. That's not all. The researchers also found that people who are frustrated in their attempts to cheat or steal are more likely than others to be attracted ...

PITTSBURGH—Aging sewer systems are spilling a considerable amount of nitrogen into urban watersheds, diminishing both the quality of water and ecosystems' habitats. However, many studies documenting the impacts of nitrogen on urban environs have not properly estimated the contribution of leaky sewer systems—until now. Aging sewer systems are spilling a considerable amount of nitrogen into urban watersheds, diminishing both the quality of water and the ecosystems' habitats. Using water samples from the Pittsburgh-based Nine Mile Run watershed, a Pitt research team reveals ...

This press release is available in French. Families with a child completing elementary school this year are now preparing their registration for high school, a transition that is often stressful for children. A new program has demonstrated that it is possible to significantly reduce stress in some of these children thanks to a new educational tool designed under the leadership of Sonia Lupien, Director of the Centre for Studies on Human Stress (CSHS) and professor at the University of Montreal. A study published in February in Neuroscience confirms the benefits of ...

Medical researchers at the University of Alberta have made a discovery that may explain how prion diseases, like chronic wasting disease and mad cow disease, adapt in order to spread between various types of animals. The research team, led by neurologist Valerie Sim, discovered that a miniscule change in the prions' makeup appears to give the disease the ability to adapt – to mimic and recreate new strains with which it comes into contact. The team has been studying this area for two years. "Prion diseases don't always successfully go from one animal to another, but when ...

URBANA – Researchers in the Evolutionary Bioinformatics Laboratory at the University of Illinois in collaboration with German scientists have been using bioinformatics techniques to probe the world of proteins for answers to questions about the origins of life. Proteins are formed from chains of amino acids and fold into three-dimensional structures that determine their function. According to crop sciences professor Gustavo Caetano-Anollés, very little is known about the evolutionary drivers for this folding. In collaboration with scientists at the Heidelberg Institute ...

A team of Spanish and Argentinean researchers have verified that the distribution of the inhabitants in each Spanish province evolves in accordance with the maximum entropy principle in the field of physics. Therefore, this evolution is predictable. The results have allowed authors to put forward a 'socio-thermodynamic' theory that applies the laws of thermodynamics to collective human behaviour. Spanish and Argentinean scientists have researched the way in which we as people group together on a large scale as a way of seeing whether there is any law or pattern that explains ...

There is good news and better news about ground-level ozone in American cities. While dangerous ozone levels have fallen in places that clamp down on emissions from vehicles and industry, a new study from Rice University suggests that a model widely used to predict the impact of remediation efforts has been too conservative. Particularly in Northeastern cities, ozone levels dropped even beyond what was anticipated by cutting emissions of nitrogen oxides (NOx) from 2002 to 2006. The study published online by the journal Atmospheric Environment suggests the Community Multiscale ...

New Rochelle, NY, March 11, 2013–Consumption of energy drinks containing caffeine may have beneficial effects on exercise but probably not for mental function. The effects of pre-exercise caffeine consumption by trained cyclists on racing times and cognitive performance were measured and are reported in Journal of Caffeine Research, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available free on the Journal of Caffeine Research website at http://www.liebertpub.com/jcr. Race performance improved for all study participants after consuming ...

A recent clinical trial found that interferonβ-1a (INF) and glatiramer acetate (GA), two of the most commonly prescribed drugs for multiple sclerosis (MS), provide no additional clinical benefit when taken together. While findings published today in Annals of Neurology, a journal of the American Neurological Association and Child Neurology Society, suggest that taking both INF and GA together was not superior to GA monotherapy in reducing relapse risk; the combination therapy does appear to reduce new lesion activity and total lesion volume. The National Institute ...

A pair of newly discovered stars is the third-closest star system to the Sun, according to a paper that will be published in Astrophysical Journal Letters. The duo is the closest star system discovered since 1916. The discovery was made by Kevin Luhman, an associate professor of astronomy and astrophysics at Penn State University and a researcher in Penn State's Center for Exoplanets and Habitable Worlds. Both stars in the new binary system are "brown dwarfs," which are stars that are too small in mass to ever become hot enough to ignite hydrogen fusion. As a result, ...

Philadelphia, PA, March 11, 2013 – Antipsychotic administration in the elderly is associated with an increased risk for cerebrovascular accident, more commonly known as stroke; a new study published in Biological Psychiatry provides additional insight into this important relationship. Antipsychotics are prescribed to elderly patients to treat symptoms such as agitation, psychosis, anxiety, insomnia, and depression. The increased risk of stroke associated with these medications was identified approximately a decade ago and has since been replicated by subsequent studies. ...

It may be better to tolerate lower oil content in algae grown for biodiesel to boost growth and overall productivity, says research from the University of Sheffield. The research shows that the commonly accepted method of depriving algae of key nutrients such as nitrogen in order to boost its oil content may be detrimental to overall oil yield in the long term. "Total oil production depends not just on the oil content of the algal cells but how quickly the cells grow and multiply," says Dr Stephen Wilkinson of the University's Department of Chemical and Biological ...

Philadelphia, Pa. (March 11, 2013) – Members of the Deaf community who suffer from mental health problems need culturally sensitive treatment to avoid misdiagnosis and inappropriate treatment, according to a report in the March Journal of Psychiatric Practice. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health. "Deaf individuals comprise a cultural and linguistic minority group within the United States, and culturally and linguistically appropriate psychiatric treatment must reflect these differences," according to Sarah A. Landsberger, ...

When it comes to body shape, diet and exercise can only take us so far. Our body shape and geometry are largely determined by genetic factors. Genetics also have an impact on our body composition – including soft fat tissue and hard bone tissue – and can lead to excess fat or osteoporosis. Now Prof. Gregory Livshits of Tel Aviv University's Department of Anatomy and Anthropology at the Sackler Faculty of Medicine, working alongside Dr. Michael Korostishevsky, has uncovered a clear genetic link between fat and bone mass. These factors, which contribute to bone metabolism, ...

WASHINGTON, DC, March 11, 2013 — Research has long linked high socioeconomic status with better health and lower mortality. But what's remained unclear is whether this association has more to do with access to resources (education, wealth, career opportunity, etc.) or the glow of high social status relative to others. Scholars call the latter "relative deprivation." To tease apart these factors, a team of investigators at Columbia University's Mailman School of Public Health led by Dr. Bruce Link, studied Baseball Hall of Fame inductees, Emmy Award winners, and former ...

SAN FRANCISCO — Heart patients who can't tolerate the side effects of cholesterol-lowering drugs may have a new option, according to a new study by researchers from the Intermountain Heart Institute at Intermountain Medical Center in Salt Lake City. Researchers found that pitavastatin, a newer cholesterol-lowering drug, may reduce the risk of heart attack, stroke and even death in up to 68 percent of patients with high cholesterol who can't tolerate other cholesterol-lowering medications due to side effects. Researchers are presenting the results of this study today ...

All living organisms rely on iron as an essential nutrient. In the ocean, iron's abundance or scarcity means all the difference as it fuels the growth of plankton, the base of the ocean's food web. A new study by biogeochemists and glaciologists at Woods Hole Oceanographic Institution (WHOI) identifies a unexpectedly large source of iron to the North Atlantic – meltwater from glaciers and ice sheets, which may stimulate plankton growth during spring and summer. This source is likely to increase as melting of the Greenland ice sheet escalates under a warming climate. The ...

Their warning comes as the Chief Medical Officer launches the UK's Antimicrobial Resistance Strategy and Action Plan, reflecting the need for a clear change in our understanding of and response to antimicrobial resistance by the public, NHS and government. Current estimates suggest that antibiotic resistance is a relatively cheap problem, they write, but such estimates do not take account of the fact that antimicrobial medicines are integral to modern healthcare. For example, antibiotics are given as standard to patients undergoing surgery, to women delivering by caesarean ...

It had been suggested that the origin of pumpkins and cucumbers can be traced back to India. This has now been confirmed on the basis of genetic analyses performed by German and Indian botanists. The study was published in the open access journal PhytoKeys. Vegetables are essential components of a healthy daily diet, not just in India but around the globe. Compared to grains and pulses, however, vegetables are under-investigated taxonomically, and information on their genome is scarce. The cucumber family, Cucurbitaceae, includes many of our favorite foods: pumpkins, ...

The temptation to steal or cheat is sometimes great — especially when the risk of being caught is low. A new study suggests that denying people the opportunity to engage in these taboo behaviors may lead them to seek out violent video games as a way of managing their frustration. The study, led by researcher Brad Bushman of Ohio State University, is published in Psychological Science, a journal of the Association for Psychological Science. Bushman and his colleagues want to understand what attracts people to violent media. In a previous study, they found that people ...
