More people are being diagnosed with eating disorders every year and the most common type is not either of the two most well known—bulimia or anorexia—but eating disorders not otherwise specified (eating disorders that don't quite reach the threshold to be defined as anorexia or bulimia), shows a study published online in BMJ Open. Few studies have investigated the incidence of eating disorders, so the authors set out to determine the incidence of diagnosed anorexia nervosa, bulimia nervosa and other non-specified eating disorders in primary care over a 10-year period ...

A Mediterranean diet with added extra virgin olive oil or mixed nuts seems to improve the brain power of older people better than advising them to follow a low-fat diet, indicates research published online in the Journal of Neurology Neurosurgery and Psychiatry. The authors from the University of Navarra in Spain base their findings on 522 men and women aged between 55 and 80 without cardiovascular disease but at high vascular risk because of underlying disease/conditions. These included either type 2 diabetes or three of the following: high blood pressure; an unfavourable ...

A new study of both computer-created and natural proteins suggests that the number of unique pockets – sites where small molecule pharmaceutical compounds can bind to proteins – is surprisingly small, meaning drug side effects may be impossible to avoid. The study also found that the fundamental biochemical processes needed for life could have been enabled by the simple physics of protein folding. Studying a set of artificial proteins and comparing them to natural proteins, researchers at the Georgia Institute of Technology have concluded that there may be no more than ...

A new diagnostic test for a worm infection that can lead to severe enlargement and deformities of the legs and genitals is far more sensitive than the currently used test, according to results of a field study in Liberia, in West Africa, where the infection is endemic. The new test found evidence of the infection – lymphatic filariasis – in many more people that the standard test had missed. The study, the first to independently evaluate the new test, was led by researchers at Washington University School of Medicine in St. Louis and funded by the Bill & Melinda Gates ...

Women who smoke during pregnancy increase the risk of both obesity and gestational diabetes, in their daughters, concludes research published in Diabetologia, the journal of the European Association for the Study of Diabetes. The study is by Dr Kristina Mattsson, Lund University, Sweden, and colleagues including Dr Matthew Longnecker from the National Institute on Environmental Health Sciences at the U.S.National Institutes of Health, North Carolina, USA. While the relation of prenatal tobacco exposure to negative outcomes in childhood has been much studied, reports on ...

Parasitic wasps switch off the immune systems of fruit flies by draining calcium from the flies' blood cells, a finding that offers new insight into how pathogens break through a host's defenses. "We believe that we have discovered an important component of cellular immunity, one that parasites have learned to take advantage of," says Emory University biologist Todd Schlenke, whose lab led the research. The Proceedings of the National Academy of Sciences (PNAS) published the results, showing how a wasp version of a conserved protein called SERCA, which normally functions ...

LEAWOOD, Kan. – Primary care practice transformation on a large scale is the cornerstone of current health care reform efforts aimed at achieving better outcomes, better value and better experience of care. Amid emerging evidence that transformation toward the patient-centered medical home model offers a viable solution in today's health care environment, the U.S. Department of Health and Human Services' Agency for Healthcare Research and Quality funded 14 studies to learn more about the processes and determinants of successful change from practices that had already demonstrated ...

Researchers have pinpointed a catalytic trigger for the onset of Alzheimer's disease – when the fundamental structure of a protein molecule changes to cause a chain reaction that leads to the death of neurons in the brain. For the first time, scientists at Cambridge's Department of Chemistry have been able to map in detail the pathway that generates "aberrant" forms of proteins which are at the root of neurodegenerative conditions such as Alzheimer's. They believe the breakthrough is a vital step closer to increased capabilities for earlier diagnosis of neurological disorders ...

Philadelphia, Pa. (May 20, 2013) - A new "telerehabilitation" approach lets physical therapists assess patients with low back pain (LBP) over the Internet, with good accuracy compared with face-to-face examinations, reports a study in the May 15 issue of Spine. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health. Taking advantage of Skype and other widely-used services may make telerehabilitation a more feasible alternative to in-person clinic visits, according to the new research by Prof. Manuel Arroyo-Morales and colleagues of ...

MAYWOOD, Il. - Nearly three out of four pregnant women experience constipation, diarrhea or other bowel disorders during their pregnancies, a Loyola University Medical Center study has found. But such bowel disorders have only minimal impacts on pregnant women's quality of life, the study found. The study by senior author Scott Graziano, MD and Payton Johnson was presented during the American Congress of Obstetricians and Gynecologists 61st Annual Clinical Meeting in New Orleans. One hundred and four pregnant women were enrolled and completed the first trimester ...

RICHLAND, Wash. – Enough Northwest wind energy to power about 85,000 homes each month could be stored in porous rocks deep underground for later use, according to a new, comprehensive study. Researchers at the Department of Energy's Pacific Northwest National Laboratory and Bonneville Power Administration identified two unique methods for this energy storage approach and two eastern Washington locations to put them into practice. Compressed air energy storage plants could help save the region's abundant wind power – which is often produced at night when winds are strong ...

Reed, all of the Department of Material Science and Engineering in Penn's School of Engineering and Applied Science. It was published in the journal Nano Letters. Detecting ...

HERALDING Entanglement, by general consensus of physicists, is the weirdest part of quantum science. To say that two particles, A and B, are entangled means that they are actually two parts of an inseparable quantum thing. An important consequence of this inherent kinship is that measuring a property of A (say, the particle's polarization) is necessarily to know the corresponding property of B, even if you're not there with a detector to observe B and even if (as explained below) the existence of that property had no prior fixed value until the moment particle ...

LA JOLLA, CA---Discovering that mouse hair has a circadian clock - a 24-hour cycle of growth followed by restorative repair - researchers suspect that hair loss in humans from toxic cancer radiotherapy and chemotherapy might be minimized if these treatments are given late in the day. The study, which appears in the early online edition of the Proceedings of the National Academy of Sciences (PNAS), found that mice lost 85 percent of their hair if they received radiation therapy in the morning, compared to a 17 percent loss when treatment occurred in the evening. The ...

Imagine a bendable tablet computer or an electronic newspaper that could fold to fit in a pocket. The technology for these devices may not be so far off. Northwestern University researchers have recently developed a graphene-based ink that is highly conductive and tolerant to bending, and they have used it to inkjet-print graphene patterns that could be used for extremely detailed, conductive electrodes. The resulting patterns are 250 times more conductive than previous attempts to print graphene-based electronic patterns and could be a step toward low-cost, foldable ...

New York, NY—May 20, 2013—The miniaturization of electronics continues to create unprecedented capabilities in computer and communications applications, enabling handheld wireless devices with tremendous computing performance operating on battery power. This same miniaturization of electronic systems is also creating new opportunities in biotechnology and biophysics. A team of researchers at Columbia Engineering has used miniaturized electronics to measure the activity of individual ion-channel proteins with temporal resolution as fine as one microsecond, producing the ...

The Amazon rain forest, popularly known as the lungs of the planet, inhales carbon dioxide as it exudes oxygen. Plants use carbon dioxide from the air to grow parts that eventually fall to the ground to decompose or get washed away by the region's plentiful rainfall. Until recently people believed much of the rain forest's carbon floated down the Amazon River and ended up deep in the ocean. University of Washington research showed a decade ago that rivers exhale huge amounts of carbon dioxide – though left open the question of how that was possible, since bark and stems ...

COLUMBUS, Ohio – New research suggests that a compound abundant in the Mediterranean diet takes away cancer cells' "superpower" to escape death. By altering a very specific step in gene regulation, this compound essentially re-educates cancer cells into normal cells that die as scheduled. One way that cancer cells thrive is by inhibiting a process that would cause them to die on a regular cycle that is subject to strict programming. This study in cells, led by Ohio State University researchers, found that a compound in certain plant-based foods, called apigenin, could ...

Individuals who learn two languages at an early age seem to switch back and forth between separate "sound systems" for each language, according to new research conducted at the University of Arizona. The research, to be published in a forthcoming issue of Psychological Science, a journal of the Association for Psychological Science, addresses enduring questions in bilingual studies about how bilingual speakers hear and process sound in two different languages. "A lot of research has shown that bilinguals are pretty good at accommodating speech variation across languages, ...

Meeting the demand for more data storage in smaller volumes means using materials made up of ever-smaller magnets, or nanomagnets. One promising material for a potential new generation of recording media is an alloy of iron and platinum with an ordered crystal structure. Researchers led by Professor Kai Liu and graduate student Dustin Gilbert at the University of California, Davis, have now found a convenient way to make these alloys and tailor their properties. "The relatively convenient synthesis conditions, along with the tunable magnetic properties, make these materials ...

Video games that pit players against human-looking characters may be more likely to provoke violent thoughts and words than games where monstrous creatures are the enemy, according to a new study by researchers at the University of Connecticut and Wake Forest University. "The Perception of Human Appearance in Video Games: Toward an Understanding of the Effects of Player Perceptions of Game Features," published in the May 2013 issue of Mass Communication and Society, comes as lawmakers and the public are freshly debating the possible risks that violent games may pose to ...

ITHACA, N.Y. – Little is known about the effect of physical education (PE) on child weight, but a new study from Cornell University finds that increasing the amount of time that elementary schoolchildren spent in gym class reduces the probability of obesity. The study represents some of the first evidence of a causal effect of PE on youth obesity, and is forthcoming in the Journal of Health Economics. An early, online version of the study can be viewed at: http://www.sciencedirect.com/science/article/pii/S0167629613000556 The research offers support for the recommendations ...

WINSTON-SALEM, N.C. – May 20, 2013 – Nearly 20 percent of kidneys that are recovered from deceased donors in the U.S. are refused for transplant due to factors ranging from scarring in small blood vessels of the kidney's filtering units to the organ going too long without blood or oxygen. But, what if instead of being discarded, these organs could be "recycled" to help solve the critical shortage of donor organs? Researchers at Wake Forest Baptist Medical Center and colleagues, reporting in the journal Biomaterials, found that human kidneys discarded for transplant can ...
