America's communities are becoming increasingly diverse, but there are still important concerns about racial and ethnic integration in the future, according to researchers. A new US2010 report shows whites, blacks, Hispanics and Asians are increasingly sharing American communities, said Barry Lee, professor of sociology and demography, Penn State. Lee, who co-wrote the report with John Iceland, professor of sociology and demography, Penn State, and Chad Farrell, associate professor of sociology, University of Alaska Anchorage, said that a universal trend toward greater ...

Nearly 1 in 3 American children are overweight or obese, but sugary sweets are often on the menu at elementary school classroom parties. But schools with a district policy or state law discouraging sugary foods and beverages were 2.5 times more likely to restrict those foods at parties than were schools with no such policy or law, according to a new study published online in the Journal of Nutrition Education and Behavior. Researchers at the University of Illinois at Chicago examined the linkages among state laws, district, and school-level policies for classroom birthday ...

GRAND RAPIDS, Mich., October 2, 2013 – A recently published study by researchers from Spectrum Health and Henry Ford Hospital suggests that surgery may be an effective treatment for epilepsy in older patients, a finding that runs counter to conventional treatment methods. "Traditionally, there has been a tendency to exclude older patients from surgery for fear of increased risk of medical or surgical complications," said Spectrum Health Medical Group neurosurgeon Sanjay Patra, MD, lead author of the study. "This study provides evidence that surgery may instead be a viable ...

A new study published today in British Journal of Pharmacology has identified that a component of grapefruit and other citrus fruits, naringenin, successfully blocks the formation of kidney cysts. Known as polycystic kidney disease, this is an inherited disorder which leads to the loss of kidney function, high blood pressure and the need for dialysis. Few treatment options are currently available. The team of scientists from Royal Holloway University, St George's, University of London and Kingston University London used a simple, single-celled amoeba to identify that ...

New classification criteria for systemic sclerosis have just been published and are more sensitive than the 1980 criteria, enabling earlier identification and treatment of this disabling autoimmune disease. The 2013 criteria, developed by a joint committee commissioned by the American College of Rheumatology (ACR) and European League Against Rheumatism (EULAR), are published in the ACR journal, Arthritis & Rheumatism. Systemic sclerosis, also known as scleroderma, is a connective tissue disease that is characterized by sclerodermatous skin changes–a hardening of tissue ...

Concerned about the effect of stress on your health and well-being? If your answer is "yes," then Arizona State University Professor Doug Granger is doing research that could impact you. Granger is pioneering the field of interdisciplinary salivary bioscience using spit. Spit conjures a variety of saying and images for most people, but for Granger and colleagues spit is also serious business. "The use of oral fluid as a research and diagnostic specimen has tremendous potential," says Granger, who is the director of ASU's new Institute for Interdisciplinary Salivary Bioscience ...

In many ways, the spread of HIV has been fueled by substance abuse. Shared needles and drug users' high-risk sexual behaviors are just some of the ways that narcotics such as cocaine have played a key role in the AIDS epidemic in much of the world. There is, however, relatively little research into how drugs can impact the body's defenses against the virus. But a new UCLA study published in the October issue of the Journal of Leukocyte Biology examines how cocaine affects a unique population of immune cells called quiescent CD4 T cells, which are resistant to the virus ...

Researchers at UCLA's Jonsson Comprehensive Cancer Center have found that mice made obese by high-calorie, high-fat diets develop abnormally high numbers of lesions known to be precursors to pancreas cancer. This is the first study to show a direct causative link in an animal model between obesity and risk of this deadly cancer. The study, published Sept. 30 in the journal Cancer Prevention Research, was led by Dr. Guido Eibl, a member of the Jonsson Cancer Center and a professor in the department of surgery at the David Geffen School of Medicine at UCLA. ...

Three researchers from the University of Huddersfield have published a paper in the Prison Service Journal looking at the important issue of what affect family ties and relationships can have on the prisoner, as well as how imprisonment can influence the family. This paper presents a qualitative evaluation of the Family Support Project (FSP) delivered at HMP New Hall, a female establishment located in West Yorkshire. The FSP was delivered by one female Family Support Officer (FSO) and managed by Lincolnshire Action Trust (LAT). Semi-structured interviews and focus groups ...

DURHAM, N.C. -- Elevated levels of radioactivity, salts and metals have been found in river water and sediments at a site where treated water from oil and gas operations is discharged into a western Pennsylvania creek. "Radium levels were about 200 times greater in sediment samples collected where the Josephine Brine Treatment Facility discharges its treated wastewater into Blacklick Creek than in sediment samples collected just upstream of the plant," said Avner Vengosh, professor of geochemistry and water quality at Duke University's Nicholas School of the Environment. The ...

This news release is available in French. Researchers at the University of Montreal and the Institut universitaire de gératrie de Montréal examined brain changes over 20 months in Parkinson's patients with and without mild cognitive impairment (MCI) at the early stages of the disease. Results showed that patients with MCI had significantly more cortical thinning and subcortical atrophy over time compared with patients without MCI, suggesting that early MCI in PD patients may indicate faster neurodegeneration. The specific pattern observed might serve as a marker for ...

DETROIT – Offering free head and neck cancer screenings annually to the community not only has the possibility of early detection, but also the opportunity – particularly in an urban city – to increase a person's understanding of risk factors that cause cancer, according to a new study from Henry Ford Hospital in Detroit. Among those who attend free head and neck cancer screenings, the study finds people who reside in an urban city like Detroit were more likely to be African American, a current smoker and have a history of treatment for some other cancer than those who ...

Researchers at Lund University in Sweden have for the first time managed to measure the internal pressure that enables the herpes virus to infect cells in the human body. The discovery paves the way for the development of new medicines to combat viral infections. The results indicate good chances to stop herpes infections in the future. A virus comprises a thin shell of protein, within which are its genes. A long-standing theory has been that a virus has high internal pressure because it is so tightly packed with genetic material. The pressure means that they can infect ...

Washington D.C., October 2, 2013 – A study published in the October 2013 issue of the Journal of the American Academy of Child and Adolescent Psychiatry found that approximately one in three teens with bipolar disorder developed substance abuse, for the first time, during 4 years of follow-up. The study also identified several risk factors that predicted who among these teens was most likely to develop substance abuse. Using data from the Course and Outcome of Bipolar Youth (COBY) study, a group of researchers led by Dr. Benjamin Goldstein, of the University of Toronto ...

BUFFALO, N.Y. -- Babies considered "early-term," born at 37 or 38 weeks after a mother's last menstrual period, may look as healthy as full-term babies born at 39-41 weeks, but a new study published by University at Buffalo physicians in JAMA Pediatrics has found that many of them are not. The study is considered the first population-based, countywide assessment of neonatal morbidity among early-term infants based on individual medical records in the U.S. "Our results show the need for an increased awareness among health care providers that even though we consider babies ...

The song of songbirds is a learned, complex behavior and subject to strong selective forces. However, it is difficult to tease apart the influence of the genetic background and the environment on the expression of individual variation in song. Scientists from the Max Planck Institute for Ornithology in Seewiesen in collaboration with international researchers now compared song and brain structure of parents and offspring in zebra finches that have been raised either with their genetic or foster parents. They also varied the amount of food during breeding. Remarkably, both ...

Bethesda, MD -- Radiofrequency ablation (RFA) leads to remission for 91 percent of patients with dysplastic Barrett's esophagus, according to new figures published in Clinical Gastroenterology and Hepatology, the official clinical practice journal of the American Gastroenterological Association. Dysplastic Barrett's esophagus is the most serious grade of the condition in which precancerous cells are detected in the esophagus. "In order to make appropriate informed decisions about the use of radiofrequency ablation, patients and providers need to be well versed in the ...

This news release is available in German. Graphene, a crystal composed of only one layer of carbon atoms arranged in a regular hexagon, is regarded as a material which is believed to be capable of performing miracles, in particular in the fields of electronics, sensor technology and display technology, but also in metrology. Only four years after the first successful preparation of graphene, its discoverers Geim and Novoselov were therefore awarded a Nobel Prize. As the original preparation method (flaking of single atomic layers of graphite) does not offer a good ...

BLOOMINGTON, Ind. -- The dramatic explosion of flowering plant species that occurred about 100 million years ago was thought to have been good news for evolving mammals, providing them with new options for food and habitat. But research by geologists at Indiana University Bloomington suggests that wasn't necessarily the case. In a study published in the journal Proceedings of the Royal Society B, David Grossnickle and P. David Polly present evidence that mammal varieties declined during the great angiosperm radiation of the mid-Cretaceous, a time when a great diversity ...

CAMBRIDGE, Mass-- In a completely unexpected finding, MIT researchers have discovered that tiny water droplets that form on a superhydrophobic surface, and then "jump" away from that surface, carry an electric charge. The finding could lead to more efficient power plants and a new way of drawing power from the atmosphere, they say. The finding is reported in a paper in the journal Nature Communications written by MIT postdoc Nenad Miljkovic, mechanical engineering professor Evelyn Wang, and two others. Miljkovic says this was an extension of previous work by the MIT ...

(WASHINGTON, October 2, 2013) – New research shows that children with an inherited genetic defect in a critical anti-inflammatory pathway have a genetic predisposition to lymphoma. Results of the study, published online today in Blood, the Journal of the American Society of Hematology (ASH), reveal an important association between the genetic defect, which causes chronic intestinal inflammation and early onset inflammatory bowel disease, and its role in cancer development in infants and children. Among the hundreds of signaling pathways in the human immune system that ...

A team of scientists from The University of Texas at Arlington and MIT has figured out how to quantitatively observe cellular processes taking place on so-called "lab on a chip" devices in a silicon environment. The new technology will be useful in drug development as well as disease diagnosis, researchers say. In a paper published in Nature's online journal Scientific Reports, the team said it overcame past limitations on quantitative microscopy through an opaque media by working with a new combination of near infrared light and a technique called quantitative phase ...

WASHINGTON, Oct. 2, 2013—For hundreds of years, optical devices like telescopes and microscopes have relied on solid lenses that slide up and down to magnify and to focus. To tune how much light is received, conventional devices use mechanical contraptions like the blades that form the adjustable aperture in cameras. To meet demands for ever smaller imaging systems, researchers are working to create entirely unconventional ways of focusing light. In pursuit of this vision, engineers from the University of Freiburg in Germany have built a novel type of imaging system inspired ...

COLUMBUS, Ohio -- In a year-long case study of a major American transportation company, researchers at The Ohio State University have uncovered the strategies that helped the company maintain safety and meet customer demand during 2012's Hurricane Sandy. One key to the company's effective response was its setup of a weather event management team, an ad hoc group that set planning priorities as the storm approached the United States, ensuring the protection of personnel and equipment in hurricane's path. More surprisingly, as landfall was imminent, the company's schedulers ...
