PHILADELPHIA – Sixty-six percent of publicly-insured children were unable to get a doctor's appointment for medical conditions requiring outpatient specialty care including diabetes and seizures, while children with identical symptoms and private insurance were turned away only 11 percent of the time, according to an audit study of specialty physician practices in Cook County, Ill. conducted by researchers from the Perelman School of Medicine and the School of Social Policy and Practice at the University of Pennsylvania. The findings are published in the June 16 issue of ...

Young adults who are web savvy, but lack knowledge about federal government, may struggle to use the web for political participation, according to a team of researchers. "There's a misconception that young adults are naturally skilled at all computer techniques," said Jens Grossklags, assistant professor of information sciences and technology, Penn State. "And while they might be comfortable on some sites and social networks, that doesn't necessarily mean that young adults know how to use the Internet for political participation." In an experiment, the researchers provided ...

The National Trust has announced that this summer looks set to be the best for butterflies in more than 30 years as population's boom, sales of butterfly products increase and butterfly imagery is adopted by big high street brands. At the half way point in the butterfly season there has been a number of record breaking early appearances from spring species thanks to the warm and dry weather, especially in April. The favourable conditions are also leading experts to predict that a number of species will produce extra generations this year. Matthew Oates, wildlife ...

New York, NY, June 15, 2011—A new Commonwealth Fund report finds that Medicaid managed care plans that are owned by publicly traded for-profit companies whose primary line of business is managing Medicaid enrollees spent an average of 14 percent of premiums on administrative costs, compared with an average of only 10 percent spent by non-publicly traded plans owned by groups of health care providers, health systems, community health centers, or clinics. Sampling health plans with at least 5,000 enrollees resulted in an initial sample of 225 Medicaid managed care plans representing ...

Malaria is a devastating disease caused by the Plasmodium parasite which is transmitted to humans by infected mosquitoes. Hundreds of millions of new cases of malaria are reported each year, and there are more than 750,000 malaria-related deaths annually. As a result, there is an urgent need for vaccines to combat infection. Now, a new study uncovers a powerful strategy for eliciting an immune response that can combat the parasite during multiple stages of its complex life cycle and describes what may be the most effective next-generation vaccination approach for malaria. ...

When populations around the globe started turning to agriculture around 10,000 years ago, regardless of their locations and type of crops, a similar trend occurred: The height and health of the people declined. "This broad and consistent pattern holds up when you look at standardized studies of whole skeletons in populations," says Amanda Mummert, an Emory University graduate student in anthropology. Mummert led the first comprehensive, global review of the literature regarding stature and health during the agriculture transition, to be published by the journal Economics ...

Mice inhabiting an area known for its high concentration of asbestos-contaminated dust, have a higher level of genetic somatic mutations, compared with other regions where asbestos pollution levels are lower. This has been shown in a new study carried out by Dr. Rachel Ben-Shlomo and Dr. Uri Shanas of the University of Haifa's Department of Biology in Oranim. "This study clearly indicates that there is a link between the higher levels of asbestos in the environment and the frequency of genetic somatic mutations in the mammals," the scientists said. Earlier studies of ...

Competing in races is the life of a runner. But, for sportspeople with sensory impairments, any race is one of obstacles. Tecnalia is working intensely on eliminating these obstacles. The system involves a series of wireless-interconnected devices in order to facilitate the starts in time trials for persons with sensory disabilities and thus enable the athlete to have a reaction time equal to his or her competitors. This is a pioneering system, developed by Tecnalia with the help of the Basque companies Enkoa and Leabai and of the Gipuzkoan Federation for Adapted Sports. ...

It is assumed that many bird species are monogamous, yet infidelity is a widespread phenomenon. The advantage for the male seems obvious as in this way he can increase the number of his offspring. A female, however, mostly faces costs. The cuckolded partners often reduce their parental care. In addition, the extra lovers also may transmit diseases. Nevertheless, some females actively seek such contacts. Researchers at the Max Planck Institute for Ornithology in Seewiesen investigated a large number of zebra finches and found a possible explanation for this behaviour. In ...

A new report launched today by the International Osteoporosis Foundation (IOF) in collaboration with the European Federation of Pharmaceutical Industry Associations (EFPIA) reveals that the burden of fractures in Europe has been vastly underestimated. The report concludes that in Europe's five largest countries and Sweden alone, an estimated 2.5 million new fragility fractures occurred in 2010 – the equivalent of 280 fractures per hour. It also showed an astounding eighty deaths per day attributable to fragility fractures. 'Osteoporosis: Burden, health care provision ...

Researchers from North Carolina State University have designed a sensor that can measure strain in structural materials and is capable of healing itself – an important advance for collecting data to help us make informed decisions about structural safety in the wake of earthquakes, explosions or other unexpected events. Engineers use sensors to measure the strain, or forces, exerted on materials used to build everything from airplanes to civil infrastructure. For example, these sensors can tell us how an airplane wing is performing in flight, and give maintenance authorities ...

There may be a natural solution to the mystery of how small amounts of a banned drug that disrupts thyroid function and plumps up livestock gets into their bodies — and the bodies of humans, scientists are reporting. Their study, which appears in ACS' Journal of Agricultural and Food Chemistry, reports the first evidence that the substance can form naturally in feed and food. Julie Vanden Bussche and colleagues explain that thiouracil is a drug that increases the weight of livestock by making them retain water. Some regulatory agencies have banned its use because the ...

The quest for better ways of encapsulating medicine so that it can reach diseased parts of the body has led scientists to harness — for the first time — living human cells to produce natural capsules with channels for releasing drugs and diagnostic agents. The report appears in ACS' journal Nano Letters. In the report, Dayang Wang and colleagues explain that the human body is very efficient at getting rid of foreign substances. Some foreign substances, such as viruses, are harmful and should be removed. But the body also considers drugs and nanoparticles — meant to treat ...

NEW BRUNSWICK, N.J. – A Rutgers University astrophysicist is part of a scientific team that has unveiled evidence of black holes being common in the early universe. The discovery, made using NASA's Chandra X-ray Observatory, shows that these young black holes grew more aggressively than scientists previously thought. The finding has important implications for how astronomers understand the early cosmos, according to Eric Gawiser, assistant professor in Rutgers' Department of Physics and Astronomy, School of Arts and Sciences. "There is a deep and mysterious connection ...

Every living plant cell and animal cell is surrounded by a membrane that helps it communicate with other cells and the outside world. These cellular membranes contain receptor molecules that serve as the cell's eyes and ears. The receptor molecules accomplish three basic things in the communication process: 1) recognize an outside signal, 2) transport that signal across the cell's membrane and 3) initiate the reading of the signal inside the cell and then initiate the cell's response to that signal. These steps are collectively known as transmembrane signaling. Transmembrane ...

FAIRFAX, Va., June 15, 2011—George Mason University scientists discovered recently that a phenomenon called a giant magnetic rope is the cause of solar storms. Confirming the existence of this formation is a key first step in helping to mitigate the adverse effects that solar storm eruptions can have on satellite communications on Earth. The discovery was made by associate professor Jie Zhang and his graduate student Xin Cheng using images from the NASA Solar Dynamic Observatory (SDO) spacecraft. Though the magnetic rope was believed to be the cause of these giant ...
