WINSTON-SALEM, N.C. – Sept. 3, 2013 – Low-income communities have particular problems getting adequate fruits and vegetables because of limited access to supermarkets and farmers markets. A new study from Wake Forest Baptist Medical Center shows that community-supported agriculture (CSA) programs may be a feasible approach for providing fresh fruits and vegetables to under-resourced communities. Lead author Sara A. Quandt, Ph.D., a professor of epidemiology and prevention at Wake Forest Baptist, said that CSAs, which link consumers to a local farm's produce over a growing ...

LA JOLLA, CA----Proteins are the chief actors in cells, carrying out the duties specified by information encoded in our genes. Most proteins live only two days or less, ensuring that those damaged by inevitable chemical modifications are replaced with new functional copies. In a new study published August 29 in Cell, a team led by researchers at the Salk Institute for Biological Studies and The Scripps Research Institute (TSRI) have now identified a small subset of proteins in the brain that persist for longer, even more than a year, without being replaced. These long-lived ...

Fires burned throughout Bolivia in late August. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite captured this natural-color image on August 31, 2013. Red outlines indicate areas where MODIS has detected high surface temperatures associated with actively burning fires. In many places, the smoke from these blazes is thick enough to completely hide the land surface below from the satellite sensor's view. In general, the smoke plumes blow toward the west and northwest. Wildfires can occur naturally in Bolivia, but the widespread burning ...

ROCHESTER, Minn. -- Mayo Clinic researchers have found a way to resynchronize cardiac motion following a heart attack using stem cells. Scientists implanted engineered stem cells, also known as induced pluripotent stem (iPS) cells, into damaged regions of mouse hearts following a heart attack. This regenerative approach successfully targeted the origin of abnormal cardiac motion, preventing heart failure. The findings appear in the September issue of the Journal of Physiology. MULTIMEDIA ALERT: Video resources, including interviews with Drs. Terzic and Yamada, are available ...

FORENSICS – Mass grave detection . . . Families of thousands of victims of social violence may gain closure, and killers may receive appropriate punishment, because of a suite of technologies able to locate clandestine graves. While investigators can find some graves, perhaps hundreds of thousands remain undiscovered. Researchers at the University of Tennessee's Forensic Anthropology Center and Oak Ridge National Laboratory are developing a method to discover graves using sensors, onboard satellites and unmanned aerial vehicles.

(Boston) - Researchers from Boston University School of Medicine (BUSM) and Boston Medical Center (BMC) have found that among obese people who had lost considerable weight, those with high insulin levels--a marker of insulin resistance in the body--were the most likely to experience better blood vessel function following the weight loss. These findings appear online in the Journal of the American College of Cardiology. Obesity has emerged as one of the most critical health care problems in the U.S. and worldwide with nearly 70 percent of the U.S. population currently ...

Big global questions face us, among them: How will we feed a growing global population without ruining the soil and polluting freshwater? Or meet our burgeoning energy demands while curbing the greenhouse gas emissions that fuel rising sea levels, flooding, drought, disease and wildfire? And what can we do to stem the extinction of thousands of other species that share the planet with us? These daunting "environmental" problems are not only in the domain of ecologists and environmental scientists. Other natural scientists, social, behavioral and economic researchers, ...

September 3, 203 - Any parent will tell you that there is no simple recipe for raising a child. Being a parent means getting hefty doses of advice – often unsolicited – from others. But such advice often fails to consider a critical factor: the child. A new review of dozens of studies involving more than 14,600 pairs of twins shows that children's genetics significantly affect how they are parented. "There is a lot of pressure on parents these days to produce children that excel in everything, socially and academically," says Reut Avinun of the Hebrew University of Jerusalem. ...

COLUMBUS, Ohio – Spool-like proteins called histones play a crucial role in packaging the nearly seven feet of DNA found in most human cells. A new study shows that a group of histones that are thought to behave the same way actually are functionally distinct proteins. The findings by researchers at the Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC – James) indicate that replication-dependent histone isoforms can have distinct cellular functions, and that changes in expression of the ...

Hashtag #doyouknowwhoswatchingyou? A new study from USC researchers sampled more than 15 million tweets, showing that some Twitter users may be inadvertently revealing their location through updates on the social media channel. The study, which appears in the current issue of the International Journal of Geoinformatics, provides important factual data for a growing national conversation about online privacy and third-party commercial or government use of geo-tagged information. "I'm a pretty private person, and I wish others would be more cautious with the types of ...

An international group of researchers from the University of Minnesota, Argonne National Laboratory and Seoul National University have discovered a groundbreaking technique in manufacturing nanostructures that has the potential to make electrical and optical devices smaller and better than ever before. A surprising low-tech tool of Scotch Magic tape ended up being one of the keys to the discovery. The research is published today in Nature Communications, an international online research journal. Combining several standard nanofabrication techniques—with the final addition ...

HOUSTON – (Sept. 3, 2013) – Clay, an abundant and cheap natural material, is a key ingredient in a supercapacitor that can operate at very high temperatures, according to Rice University researchers who have developed such a device. The Rice group of materials scientist Pulickel Ajayan reported today in Nature's online journal, Scientific Reports that the supercapacitor is reliable at temperatures of up to 200 degrees Celsius (392 degrees Fahrenheit) and possibly beyond. It could be useful for powering devices for use in extreme environments, such as oil drilling, the ...

MADISON, Wis. — Once every 30 years or so, or roughly one Saturnian year, a monster storm rips across the northern hemisphere of the ringed planet. In 2010, the most recent and only the sixth giant storm on Saturn observed by humans began stirring. It quickly grew to superstorm proportions, reaching 15,000 kilometers (more than 9,300 miles) in width and visible to amateur astronomers on Earth as a great white spot dancing across the surface of the planet. Now, thanks to near-infrared spectral measurements taken by NASA's Cassini orbiter and analysis of near-infrared ...

London (Wednesday 04 September 2013). Having a tattoo can reduce your chance of getting a job, but it depends on where the tattoo is, what it depicts and if the job involves dealing with customers, new research says. Dr Andrew R. Timming told the British Sociological Association conference on work, employment and society in Warwick today [Wednesday 4 September] that employers were prone to view tattoos negatively. Dr Timming, of the School of Management at the University of St Andrews, said he had spoken to 15 managers involved in hiring staff about their reaction to ...

London (Wednesday 04 September 2013). Having a degree or other qualifications is no protection against under-employment in Britain, new research shows. The British Sociological Association's conference on work, employment and society in Warwick heard today [Wednesday 4 September] that qualified women were more likely to be under-employed than unqualified ones. Qualified men were just as likely to be under-employed as unqualified ones. Dr Surhan Cam, of School of Social Sciences at Cardiff University, said that as working hours were cut during the economic slowdown, ...

Many American parents yell or shout at their teenagers. A new longitudinal study has found that using such harsh verbal discipline in early adolescence can be harmful to teens later. Instead of minimizing teens' problematic behavior, harsh verbal discipline may actually aggravate it. The study, from researchers at the University of Pittsburgh and the University of Michigan, appears in the journal Child Development. Harsh verbal discipline happens when parents use psychological force to cause a child to experience emotional pain or discomfort in an effort to correct ...

WASHINGTON, September 4, 2013 — In the Middle East and North Africa, heart disease, stroke, and diabetes are causing a massive amount of premature death and disability. People in Latin America and the Caribbean are living longer on the whole, yet they face increasing threats from chronic diseases. Mortality has declined in many South Asian countries, yet the number of deaths by non-communicable diseases and self-harm has skyrocketed since 1990. These are some of the findings released by the World Bank Group and the Institute for Health Metrics and Evaluation (IHME) in ...

PHILADELPHIA — A new, highly sensitive method to detect genetic variations that initiate colon cancer could be readily used for noninvasive colon cancer screening, according to a study published in Cancer Prevention Research, a journal of the American Association for Cancer Research. "Tumor cells are released into stool from the surface of precancers and early-stage colon cancers, but detecting a cancer-initiating genetic mutation among a large quantity of normal DNA from a patient's stool is like looking for a needle in a haystack," said Bettina Scholtka, Ph.D., assistant ...

With a growing incidence of cardiovascular disease in Asia, lifestyle modification such as weight loss and routine exercise plays an important role in early primary cardiovascular disease prevention. While it is widely known that patients with cardiovascular conditions will benefit from participating in a structured cardiac rehabilitation programme, particularly in a convenient and affordable community-based setting, there is no published data that showed the effectiveness of such a programme in the Asian population to date. With the idea of health promotion in mind, ...

A Swedish archaeological expedition from the University of Gothenburg has excavated a previously unknown part of the Bronze Age city Hala Sultan Tekke (around 1600-1100 BC). The finds include a facility for extraction of copper and production of bronze objects, evidence of production of luxurious textiles, as well as ceramics and other objects imported from all over the Mediterranean but also from central Europe. 'One of our conclusions is that the Bronze Age culture in Hala Sultan Tekke played a central role in the Eastern Mediterranean. Cyprus served as an important ...

Recent research, by Dr Selvaraj Velayutham published in a forthcoming issue of The Economic and Labour Relations Review, published by SAGE, details the exploitation of Indian immigrant workers in Australia on 457 visas. Whilst the exploitation was often by fellow-countrymen, it is the 457 visa system that makes this exploitation possible. Unless temporary immigrants accept the poor conditions offered, they face deportation. In effect they have been tricked into coming to Australia by false promises, and have often had to borrow heavily to pay dishonest recruitment agents. ...

That old "best friend" can get a bit tiresome, all that rolling over, shaking paws, long walks and eating every crumb of food off the floor. But, what if there were a way to command your dog with a remote control, or even via your smart phone...or even without hands? Jeff Miller and David Bevly of the Department of Mechanical Engineering, at Auburn University, Auburn, Alabama, have devised just such a system and describe details in a forthcoming issue of the International Journal of Modelling, Identification and Control. The device based on a control suite with a microprocessor, ...
