Compared to younger adults, older people are less adept at reading emotion in their spouse's face. But when their spouse isn't present, older and younger adults are equally able to discern their significant others' moods. These findings, published in Psychological Science, a journal of the Association for Psychological Science, suggest that older adults retain the ability to make accurate judgments about others emotions using their acquired knowledge, but not sensory cues. "When judging others' emotions in real life, people do not exclusively rely on emotional expressions," ...

TORONTO, Sept. 10, 2013—Race or ethnicity can be a significant clue in the United States as to who will survive a kind of stroke known as a subarachnoid hemorrhage and who will be discharged to institutional care, a new study has found. Compared to Caucasians, Asian/Pacific Islander patients were more likely and Hispanic patients less likely to die of a subarachnoid hemorrhage, or SAH, while in the hospital. African-American patients were more likely than Caucasians to require institutional care following discharge from the hospital, although their risk of death while ...

Farmers can now get a birds-eye view ­of their fields – in full HD – thanks to Michigan State University landing its first drone. MSU researchers are using its first unmanned aerial vehicle to help farmers maximize yields by improving nitrogen and water management and reducing environmental impact such as nitrate leaching or nitrous oxide emissions. For this initiative, MSU's UAV measures how crops react to stress, such as drought, nutrients deficiency or pests. The drone flies over the field documenting the field's status ­– down to centimeters. The portrait gives ...

Case Western Reserve University is part of a landmark study that has discovered four novel gene variations which are associated with blood pressure. The 19-site meta-analysis, involving nearly 30,000 African-Americans, also found that the set of genetic mutations are also associated with blood pressure across other populations. Epidemiology and biostatistics professor Xiaofeng Zhu, PhD, is co-senior author of the paper, which appears in The American Journal of Human Genetics. The Continental Origins and Genetic Epidemiology Network (COGENT) consortium conducted the ...

Bilingual speakers can switch languages seamlessly, likely developing a higher level of mental flexibility than monolinguals, according to Penn State linguistic researchers. "In the past, bilinguals were looked down upon," said Judith F. Kroll, Distinguished Professor of Psychology, Linguistics and Women's Studies. "Not only is bilingualism not bad for you, it may be really good. When you're switching languages all the time it strengthens your mental muscle and your executive function becomes enhanced." Fluent bilinguals seem to have both languages active at all times, ...

(Washington, DC) – A recent study provides the first empirical evidence to show that active and engaged television viewing can help to accelerate language change. The study, "Television can also be a factor in language change: Evidence from an urban dialect," to be published in the September 2013 issue of the scholarly journal Language, is authored by Jane Stuart-Smith, English Language/Glasgow University Laboratory of Phonetics, Glasgow University; Claire Timmins, Speech & Language Therapy, Strathclyde University; Gwilym Pryce, Urban Studies, Glasgow University, and Barrie ...

Hot and extremely dry conditions combined with shifting winds and low humidity continue to plague firefighter efforts at the Rim Fire in California. To date over 254,000 acres have been burned. Pockets of unburned vegetation around Thompson Peak and at the South edge of the fire's perimeter continue to burn. Fire crews successfully contained 15 spot fires along the Tioga Road today and the plan is to set a fire in a three quarter mile section of land within the park to contain an additional spot fire. Firefighters often have to set controlled burns in areas of dry tinder ...

PORTLAND, Ore. – A new analysis concludes that large numbers of patients in advanced stages of kidney disease are inappropriately being prescribed statins to lower their cholesterol – drugs that offer them no benefit and may increase other health risks such as diabetes, dementia or muscle pain. The findings, which were published in the American Journal of Cardiovascular Drugs as a review of multiple studies, raise serious questions about the value of cholesterol-lowering therapies in kidney disease. The issue is important, the researchers say, because the incidence ...

WASHINGTON — The science and engineering capabilities that underpin the nuclear weapons stockpile stewardship and nonproliferation missions at the nation's three national security laboratories are "healthy and vibrant," says a new report from the National Research Council. The committee that wrote the report found no problems with the quality of science and engineering that would prevent certification of the stockpile. However, the report identifies several issues that, if not addressed, have the potential to erode the ability to perform high-quality work at the laboratories. ...

WASHINGTON -- Delivery of cancer care in the U.S. is facing a crisis stemming from a combination of factors -- a growing demand for such care, a shrinking oncology work force, rising costs of cancer care, and the complexity of the disease and its treatment, says a new report from the Institute of Medicine. The report recommends ways to respond to these challenges and improve cancer care delivery, including by strengthening clinicians' core competencies in caring for patients with cancer, shifting to team-based models of care, and communicating more effectively with patients. ...

This news release is available in French. Montreal, September 10, 2013 — Dreams of washboard abs and toned arms may seem to be the main motivation for the average teen to lace up their running shoes. But over 1,000 Montreal high school students disagree. Teens, it seems, are smarter than their parents when it comes to approaching exercise as something that affects one's whole body. In a recent study on adolescent perceptions surrounding physical activity, James Gavin, professor in Concordia University's Department of Applied Human Sciences, found that teens are just ...

A University of Colorado Cancer Center study published today in the journal Cancer shows that the current criteria used to match lung cancers with the drug crizotinib may miss some patients who could benefit from the drug. The findings suggest that doctors should look closer at borderline or atypical ALK-negative cases, and could widen the population of lung cancer patients offered treatment with crizotinib or other ALK-inhibitor drugs. ALK stands for anaplastic lymphoma kinase, a gene that is turned off in most adult tissues in the body, but which can be re-activated ...

JUPITER, FL, September 10, 2013 – The human brain is exquisitely adept at linking seemingly random details into a cohesive memory that can trigger myriad associations—some good, some not so good. For recovering addicts and individuals suffering from post-traumatic stress disorder (PTSD), unwanted memories can be devastating. Former meth addicts, for instance, report intense drug cravings triggered by associations with cigarettes, money, even gum (used to relieve dry mouth), pushing them back into the addiction they so desperately want to leave. Now, for the first time, ...

Karin B. Nelson, M.D., scientist emeritus at the National Institute of Neurological Disorders and Stroke (NINDS), part of the National Institutes of Health, and her colleagues from the University of Sydney, the University of Western Australia and Sydney Adventist Hospital in Australia examined the degree to which four specific risk factors contributed to cerebral palsy and young infant death. The risk factors were asphyxial birth events (incidences during labor and delivery that had the potential to interfere with oxygen getting to the newborn's brain), inflammation (signs ...

WASHINGTON and NEW YORK—A new study by researchers at the George Washington University School of Public Health and Health Services (SPHHS) finds no evidence that primary care physicians provide "second-class" care to Medicaid, uninsured and other patients who rely on the nation's safety-net system. The study, which appears in the September issue of the journal Health Affairs, challenges previous claims that the care provided to low-income and vulnerable patients is substandard. The new study was supported by the Geiger/Gibson RCHN Community Health Foundation Research Collaborative. "The ...

About 5 percent of U.S. children and teens are "severely obese" — a newly defined class of risk, according to an American Heart Association scientific statement published online in the journal Circulation. "Severe obesity in young people has grave health consequences," said Aaron Kelly, Ph.D., lead author of the statement and a researcher at the University of Minnesota Medical School in Minneapolis. "It's a much more serious childhood disease than obesity." While childhood obesity rates are starting to level off, severe obesity has increased, Kelly said. Severely ...

Boston, MA -- Blacks are more likely than whites to sleep less than seven hours a night and the black-white sleep disparity is greatest in professional occupations, according to a new study from Harvard School of Public Health (HSPH). "Short sleep" has been linked with increased risk of health problems, including obesity, high blood pressure, diabetes, heart disease, and death. The researchers also found that black professionals had the highest prevalence of short sleep and white professionals had the lowest prevalence. The study appears online September 9, 2013 in the ...

UK commercial baby foods don't meet infants' dietary weaning needs, because they are predominantly sweet foods that provide little extra nutritional goodness over breast milk, indicates research published online in Archives of Disease in Childhood. Furthermore, they are promoted for infants from the age of four months -- an age when they should still be on an exclusive breast milk diet, say the researchers. They wanted to find out what sort of products are available in the UK for weaning infants from a predominantly milk based diet to a family food based diet, and to ...

A lack of clearly defined goals, a surfeit of box ticking and regulation, and highly variable staff support are stifling the almost universal desire to provide high quality care in the English NHS, finds the largest ever analysis of its culture and behaviours, published online in BMJ Quality & Safety. While there are many examples of exemplary and innovative care, the sorts of issues which came to light in this year's Robert Francis Inquiry into the failings at Mid-Staffordshire NHS Foundation Trust are likely to be found elsewhere, even if not to the same extent, suggest ...

Men with smaller testes than others are more likely to be involved in hands-on care of their toddlers, a new study conducted by anthropologists at Emory University finds. The Proceedings of the National Academy of Sciences (PNAS) published the results of the study Sept. 9. Smaller testicular volumes also correlate with more nurturing-related brain activity in fathers as they are looking at photos of their own children, the study shows. "Our data suggest that the biology of human males reflects a trade-off between investments in mating versus parenting effort," says Emory ...

ANN ARBOR, Mich. — Nearly one in five older adults who have common operations will end up in the emergency department within a month of their hospital stay, a new study finds – a surprisingly high number found in the first national look at the issue. What's even more surprising? The wide variation between hospitals, in keeping their older surgery patients from needing emergency care after surgery on their hearts, hips, backs, colons and major blood vessels. Some hospitals had four times the rate of post-surgery emergency care for their patients, compared with others. In ...
