Delineation of the origin of the retrovirus known as XMRV from the genomes of laboratory mice indicates that the virus is unlikely to be responsible for either prostate cancer or chronic fatigue syndrome in humans, as has been widely published. The virus arose because of genetic recombination of two mouse viruses. Subsequent infection of lab experiments with XMRV formed the basis of the original association. Reporting in Science, Vinay Pathak, Ph.D., and his research team from the National Cancer Institute (NCI), part of the National Institutes of Health, in collaboration ...

A survey of nearly 4,000 Americans finds that obese women reported significantly worse health than obese men. Blacks who were overweight also reported better health than blacks in the normal or obese weight categories. Respondents were divided into three categories: normal, overweight, or obese, according to their height and weight. The survey results are published online in the June issue of Springer's journal Quality of Life Research and they come from a study funded by the National Institute on Aging. During the survey, researchers conducted comprehensive telephone ...

"When we talk about supporting adaptation to climate change, what we mean is supporting resilience at the community level," says Noorjehan Johnson, Vanier Canada Graduate Scholar in Cultural Anthropology at McGill University. "In the Arctic, much of the resilience is fostered through community institutions, which are playing an increasingly important role in crafting a local-level response to climate change." Johnson's research has taken her to Kanngiqtugaapik (Clyde River) on Baffin Island, Nunavut. There, she has been finding out how Inuit communities are adapting to ...

Washington, DC, May 31, 2011 -- Cell phones used by patients and their visitors were twice as likely to contain potentially dangerous bacteria as those of healthcare workers (HCW), according to a study published in the June issue of the American Journal of Infection Control, the official publication of APIC - the Association for Professionals in Infection Control and Epidemiology. A team of researchers from the Department of Medical Microbiology at Inonu University in Malatya, Turkey collected swab samples from three parts of cell phones—the keypad, microphone and ear ...

A Queen's University professor is helping standardize practices for healthcare ethicists who consult and give guidance on medical ethics issues to doctors, nurses and patients across the country. "It's time for healthcare ethicists to have some formal practice guidelines, a governing code of ethics, and uniform education and certification standards," says Cheryl Cline, Director of the Office of Bioethics in the Faculty of Health Sciences and Clinical Ethicist at Kingston General Hospital. "Our job is to provide Canadian patients and their families with high quality ethics ...

How do people who speak more than one language keep from mixing them up? How do they find the right word in the right language when being fluent in just one language means knowing about 30,000 words? That's what science has wondered about for decades, offering complicated theories on how the brain processes more than one language and sometimes theorizing that bilingualism degrades cognitive performance. But University of Kansas psycholinguist Mike Vitevitch thinks that complicated explanations of how the brain processes two or more languages overlook a straightforward ...

Alexandria, VA –Next week marks the 67th anniversary of D-Day, when the Allies stormed the beaches at Normandy, France, and changed the face of World War II. Not much evidence of the war remains in Normandy: a few dilapidated relics, a cemetery, a war memorial. But something else was left behind that cannot be seen by the naked eye: shrapnel and iron and glass beads left over from the D-Day invasions in 1944. Two geologists visited Omaha Beach in 1988 and collected samples of the sand. Upon returning to their labs, they examined the sand under microscopes and discovered ...

In the 30 years since the first reported cases of a mysterious illness now known as AIDS, researchers have made extraordinary advances in understanding, treating and preventing the disease. Now the challenge, according to experts at the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, is to build on those successes to control and, ultimately, end the HIV/AIDS pandemic. In an article published online today by the Annals of Internal Medicine, Anthony S. Fauci, M.D., NIAID Director, and Carl W. Dieffenbach, Ph.D., ...

Each time you see a person that you know, your brain rapidly and seemingly effortlessly recognizes that person by his or her face. Until now, scientists believed that only a couple of brain areas mediate facial recognition. However, Carnegie Mellon University's Marlene Behrmann, David Plaut and Adrian Nestor have discovered that an entire network of cortical areas work together to identify faces. Published in the current issue of the Proceedings of the National Academy of Sciences (PNAS), their findings will change the future of neural visual perception research and ...

CAMDEN – If you think that you're using humanely produced eggs for your omelets or deviled eggs, think again. Egg companies recognize that most Americans care about the welfare of farmed animals and many market their eggs with labels claiming the hens were treated well. But a Rutgers–Camden law professor warns that many of the animal welfare claims on egg cartons aren't all that they're cracked up to be. Sheila Rodriguez, a clinical associate professor at the Rutgers School of Law–Camden, asserts that food consumers have a right to know how farm animals are raised and, ...

CHAMPAIGN, lll. — Blood clotting is a complicated business, particularly for those trying to understand how the body responds to injury. In a new study, researchers report that they are the first to describe in atomic detail a chemical interaction that is vital to blood clotting. This interaction – between a clotting factor and a cell membrane – has baffled scientists for decades. The study appears online in the Journal of Biological Chemistry. "For decades, people have known that blood-clotting proteins have to bind to a cell membrane in order for the clotting reaction ...

A team of Scripps Research Institute scientists has found a key biological mechanism underpinning the transition to alcohol dependence. This finding opens the door to the development of drugs to manage excessive alcohol consumption. "Our focus in this study, like much of our lab's research, was to examine the role of the brain's stress system in compulsive alcohol drinking driven by the aversive aspects of alcohol withdrawal," said Scripps Research Associate Professor Marisa Roberto, Ph.D., senior author of the study. "A major goal for this study," added Research Associate ...

In the treeless, flat Prairie, you'd think a city would provide a good home for bats who like to snuggle up and roost in trees and buildings. But researchers at the University of Calgary made the surprising discovery that the urban landscape is far from ideal for these animals. "I was really surprised," says Dr. Joanna Coleman, a sessional lecturer and recent PhD graduate in biological sciences at the University of Calgary and lead author of the study. "I fully expected bats to benefit from the expected increase in availability of roosts and food – insects -- in the city. ...

PHILADELPHIA — Engineering structures on the smallest possible scales — using molecules and individual atoms as building blocks — is both physically and conceptually challenging. An interdisciplinary team of researchers at the University of Pennsylvania has now developed a method of computationally selecting the best of these blocks, drawing inspiration from the similar behavior of proteins in making biological structures. The team was led by postdoctoral fellow Gevorg Grigoryan and professor William DeGrado of the Department of Biochemistry and Biophysics in Penn's Perelman ...

(Garrison, NY) In a feature article in The New Republic, Daniel Callahan and Sherwin Nuland propose a radical reinvention of the American medical system requiring new ways of thinking about living, aging, and dying. They argue that a sustainable—and more humane— medical system in the U.S. will have to reprioritize to emphasize public health and prevention for the young, and care not cure for the elderly. An interesting twist on their argument, which would aim to bring everyone's life expectancy up to an average age of 80 years but give highest priority for medical treatment ...

Cutting back on sleep drastically reduces a healthy young man's testosterone levels, according to a study published in the June 1 issue of the Journal of the American Medical Association (JAMA). Eve Van Cauter, PhD, professor in medicine and director of the study, found that men who slept less than five hours a night for one week in a laboratory had significantly lower levels of testosterone than when they had a full night's sleep. Low testosterone has a host of negative consequences for young men, and not just in sexual behavior and reproduction. It is critical in building ...

This release is available in Spanish. Laboratory hamsters that were fed rations spiked with blueberry peels and other blueberry-juice-processing leftovers had better cholesterol health than hamsters whose rations weren't enhanced with blueberries. That's according to a study led by U.S. Department of Agriculture (USDA) chemist Wallace H. Yokoyama. Yokoyama pointed out that further research is needed to confirm whether the effects observed in hamsters hold true for humans. He works at the Western Regional Research Center operated in Albany Calif., by the Agricultural ...

AUGUSTA, Ga. – A facelift incision and robotics can help surgeons safely remove a portion of a diseased thyroid from some patients without the characteristic neck scar. Georgia Health Sciences University surgeons developed the technique utilizing the remote access capabilities of robots, experience gained from another no-neck-scar approach through the armpit and earlier success removing the largest salivary gland from the lower jaw region. "It is outpatient, it doesn't require a surgical drain and it has the advantage of no neck scar," said Dr. David Terris, Chairman ...

COLUMBUS, Ohio – New research proves that a change in a particular gene can identify which patients with a specific kind of brain cancer will respond better to treatment. Testing for the gene can distinguish patients with a more- or less-aggressive form of glioblastoma, the most common and an often-fatal type of primary brain cancer, and help guide therapy, the researchers say. The prospective study looked at a gene called MGMT in tumors removed from 833 glioblastoma patients. It showed that when the gene promoter is altered by a chemical change called methylation, patients ...
