Healthy doctors make healthy patients, study finds
2013-04-08
Patients are more likely to follow preventive health practices like getting a flu shot or mammography if their doctors do likewise, researchers at the University of British Columbia and in Israel have discovered.
"We found that patients whose physicians adhered to the recommended screening or vaccination practices were significantly more likely to also undergo screening or vaccination compared with patients of non-compliant physicians," said Dr. Erica Frank of UBC's School of Population and Public Health.
Dr. Frank worked with three Israeli researchers and their findings ...
Migraine triggers tricky to pinpoint
2013-04-08
WINSTON-SALEM, N.C. – April 8, 2013 – Women often point to stress, hormones, alcohol, or even the weather as possible triggers for their migraines. But a new study from Wake Forest Baptist Medical Center found that it is nearly impossible for patients to determine the true cause of their migraine episodes without undergoing formal experiments.
The majority of migraine sufferers try to figure out for themselves what causes their headaches based on real world conditions, said lead author Timothy T. Houle, Ph.D, associate professor of anesthesia and neurology at Wake Forest ...
Cry me a river of possibility: Scientists design new adaptive material inspired by tears
2013-04-08
Imagine a tent that blocks light on a dry and sunny day, and becomes transparent and water-repellent on a dim, rainy day. Or highly precise, self-adjusting contact lenses that also clean themselves. Or pipelines that can optimize the rate of flow depending on the volume of fluid coming through them and the environmental conditions outside.
A team of researchers at the Wyss Institute at Harvard University and Harvard's School of Engineering and Applied Sciences (SEAS) just moved these enticing notions much closer to reality by designing a new kind of adaptive material ...
Copying is social phenomenon, not just learning, say scientists
2013-04-08
Mimicking the behaviour of mum and dad has long been considered a vital way in which children learn about the world around them.
Now psychologists at The University of Nottingham have shown that copying unnecessary behaviour is more likely to be a social phenomenon than part of the practical process of acquiring new skills.
In their study, published today in the journal Current Biology, the scientists found that autistic children, who have profound difficulty in engaging in social situations, were less likely to copy unnecessary behaviour when learning a new task.

Technique finds software bugs in surgical robots and helps developers fix flaws, ensure safety
2013-04-08
PITTSBURGH—Surgical robots could make some types of surgery safer and more effective, but proving that the software controlling these machines works as intended is problematic. Researchers at Carnegie Mellon University and the Johns Hopkins University Applied Physics Laboratory have demonstrated that methods for reliably detecting software bugs and ultimately verifying software safety can be applied successfully to this breed of robot.
They used theorem-proving techniques to analyze a control algorithm for a research robot that would help a surgeon perform surgery at ...
Fatheads: How neurons protect themselves against excess fat
2013-04-08
We're all fatheads. That is, our brain cells are packed with fat molecules, more of them than almost any other cell type. Still, if the brain cells' fat content gets too high, they'll be in trouble. In a recent study in mice, researchers at Johns Hopkins pinpointed an enzyme that keeps neurons' fat levels under control, and may be implicated in human neurological diseases. Their findings are published in the May 2013 issue of Molecular and Cellular Biology.
"There are known connections between problems with how the body's cells process fats and neurodegenerative diseases ...
Legislation can curb discrimination against gays and lesbians in employment situations
2013-04-08
Antidiscrimination laws can have a significant positive impact on how gays and lesbians are treated in employment situations, according to new research from Rice University. The study on public awareness of sexual-orientation employment-antidiscrimination laws is one of the first to provide empirical evidence for the likely impact of pending antidiscrimination legislation.
"In many U.S. states and localities (including much of Texas), gays and lesbians remain unprotected from employment discrimination," said Laura Barron, a 2008 Rice alumna and now personnel research ...
For breast cancer screening, 1 size doesn't fit all
2013-04-08
Philadelphia, PA, April 8, 2013 – Although mammography, the gold standard of breast cancer screening, reduces breast cancer mortality, it has important limitations. Critics point to reduced sensitivity for women with dense breasts, a high rate of false positives leading to excessive biopsies, and concerns about long-term effects of repeated radiation. With greater understanding of risk stratification, the authors of this review envision a re-thinking of the typical breast cancer paradigm to include new technologies that allow a more individualized approach that integrates ...
Religious, nonreligious organizations may have similar impact on immigrants
2013-04-08
Religious and nonreligious organizations may have a similar impact on the ability of immigrants to acclimate to life in the U.S., despite the organizations' different motivations for providing charitable services, according to new research from Rice University.
"There's been a lot of discussion as to whether religious organizations offer some special or unique benefit to immigrant groups that will help them better adapt to American society," said the study's lead author, Elaine Howard Ecklund, the Herbert S. Autrey Professor of Sociology and director of Rice's Religion ...
Link between obesity and polycystic ovary syndrome may be exaggerated
2013-04-08
AUGUSTA, Ga. – The relationship between obesity and polycystic ovary syndrome may be exaggerated, likely because the women who actively seek care for the condition tend to be heavier than those identified through screening of the general population, researchers report.
PCOS affects about 10 percent of women and is characterized by excess male hormone, irregular ovulation and menstruation as well as increased risk of metabolic diseases often associated with being overweight.
The study in the Journal of Clinical Endocrinology & Metabolism looked at what have long been ...
Nanowires have the power to revolutionize solar energy
2013-04-08
Imagine a solar panel more efficient than today's best solar panels, but using 10 000 times less material. This is what EPFL researchers expect given recent findings on these tiny filaments called nanowires. Solar technology integrating nanowires could capture large quantities of light and produce energy with incredible efficiency at a much lower cost. This technology is possibly the future for powering microchips and the basis for a new generation of solar panels.
Despite their size, nanowires have tremendous potential for energy production. "These nanowires capture ...
Birds find ways to avoid raising cuckoos' young
2013-04-08
Some species of birds reproduce not by rearing their own young, but by handing that task on to adults of other species. Known as brood parasitism, this habit has been most thoroughly researched in the cuckoo. Previous research has found, however, that the nests of martins and swallows in Europe are rarely parasitized by cuckoos. A new study by Wen Liang from the Hainan Normal University in China and his colleagues suggests that swallows build their nests close to humans to reduce their susceptibility to brood parasitism. The findings are published in Springer's journal ...

Research examines corporate communications in the 'gilded age' of free speech
2013-04-08
An analysis of U.S. Supreme Court decisions suggests "historical amnesia" regarding the growing power of speech rights for corporations in electronic media, versus the First Amendment rights of individuals. Jeff Blevins, associate professor and head of the University of Cincinnati's Department of Journalism, will present his research on Tuesday, April 9, at the 58th annual convention of the Broadcast Education Association in Las Vegas.
Blevins' presentation, titled "Historical Amnesia in First Amendment Jurisprudence on Corporate Power and Electronic Media," suggests ...
Bird flu mutation study offers vaccine clue
2013-04-08
Scientists have described small genetic changes that enable the H5N1 bird flu virus to replicate more easily in the noses of mammals.
So far there have only been isolated cases of bird flu in humans, and no widespread transmission as the H5N1 virus can't replicate efficiently in the nose. The new study, using weakened viruses in the lab, supports the conclusions of controversial research published in 2012 which demonstrated that just a few genetic mutations could enable bird flu to spread between ferrets, which are used to model flu infection in humans.

Older patients have higher expectations and are more satisfied with healthcare
2013-04-08
London (08 April 2013). New research on patients' experiences of health services and how these relate to their expectations and satisfaction, published by the Journal of the Royal Society of Medicine, reveals that older people have higher expectations of their care and that they believe that their expectations are being met. The research questions prevailing stereotypes that characterise older patients as being satisfied with their care because their expectations are lower.
Patients visiting their GP and hospital outpatient departments were surveyed before and after their ...

Tortuous paths hamper ion transport
2013-04-08
Mobile phone batteries that last longer, car batteries that enable you to drive further, storage that accumulates a lot of energy from wind and solar generators: many applications require better batteries. The research essentially focuses on three aspects here: researchers want to increase the energy density – in other words store more energy in a smaller battery. They are also looking to improve the discharging and charging speed by changing and controlling the material, shape and size of the electrochemically active particles and the structure of the battery electrodes ...
