Roundworms Reveal Health Benefits Of Omega Fatty Acids
Date: Feb-25-2013New research in roundworms suggests that omega-6 fatty acids may trigger the body's natural way of recycling of faulty or worn-out cell components, a process thought to be linked to human health and longevity and whose absence may be involved in a number of diseases...
Distraction Learning Helps Older Adults Perform Better In Memory Tests
Date: Feb-25-2013Scientists at Baycrest Health Sciences' Rotman Research Institute (RRI) and the University of Toronto's Psychology Department have found compelling evidence that older adults can eliminate forgetfulness and perform as well as younger adults on memory tests. Scientists used a distraction learning strategy to help older adults overcome age-related forgetting and boost their performance to that of younger adults...
Learning To Use Facebook May Give Adults Older Than 65 A Cognitive Boost
Date: Feb-25-2013For older adults looking to sharpen their mental abilities, it might be time to log on to Facebook. Preliminary research findings from the University of Arizona suggest that men and women older than 65 who learn to use Facebook could see a boost in cognitive function. Janelle Wohltmann, a graduate student in the UA department of psychology, set out to see whether teaching older adults to use the popular social networking site could help improve their cognitive performance and make them feel more socially connected...
Linguistics And Biology Researchers Propose A New Theory On The Deep Roots Of Human Speech
Date: Feb-25-2013"The sounds uttered by birds offer in several respects the nearest analogy to language," Charles Darwin wrote in "The Descent of Man" (1871), while contemplating how humans learned to speak. Language, he speculated, might have had its origins in singing, which "might have given rise to words expressive of various complex emotions." Now researchers from MIT, along with a scholar from the University of Tokyo, say that Darwin was on the right path...
Resources And Barriers To Physical Activity Studied In Texas Border Towns
Date: Feb-25-2013Obesity, diabetes and other ailments plague impoverished communities at higher rates than the general United States population. In rural Texas border towns, or colonias, Mexican-American residents are at an even greater risk for chronic health problems. Physical activity has shown to reduce the risks for chronic health problems, but "few Mexican-American and lower-income Americans, including children, engage in physical activity that bring about health benefits," according to a study conducted by Baylor University and Texas A&M University researchers...
Heavy Loads On The Shoulders Can Cause Nerve Damage In The Hands And Fingers
Date: Feb-25-2013Trudging from place to place with heavy weights on our backs is an everyday reality, from schoolchildren toting textbooks in backpacks to firefighters and soldiers carrying occupational gear. Muscle and skeletal damage are very real concerns. Now Tel Aviv University researchers say that nerve damage, specifically to the nerves that travel through the neck and shoulders to animate our hands and fingers, is also a serious risk. Prof. Amit Gefen of TAU's Department of Biomedical Engineering and Prof. Yoram Epstein of TAU's Sackler Faculty of Medicine, along with PhD student Amir Hadid and Dr...
Soldiers And PTSD: Why Some Develop It While Others Don't
Date: Feb-25-2013Pre-war vulnerability is just as important as combat-related trauma in predicting whether veterans' symptoms of post-traumatic stress disorder (PTSD) will be long-lasting, according to new research published in Clinical Psychological Science, a journal of the Association for Psychological Science. Researcher Bruce Dohrenwend and colleagues at Columbia's Mailman School of Public Health and the New York State Psychiatric Institute found that traumatic experiences during combat predicted the onset of the full complement of symptoms, known as the PTSD "syndrome," in Vietnam veterans...
Older African American Women At Increased Risk For Endocrine Disorder, The Most Common Cause Of Elevated Calcium Levels
Date: Feb-25-2013Unusually high calcium levels in the blood can almost always be traced to primary hyperparathyroidism, an undertreated, underreported condition that affects mainly women and the elderly, according to a new study by UCLA researchers. The condition, which results from overactive parathyroid glands and includes symptoms of bone loss, depression and fatigue that may go undetected for years, is most often seen in African American women over the age of 50, the researchers discovered...
The Effects Of Early Life Stress On Heart Function In Later Life
Date: Feb-25-2013Early life stress like that experienced by ill newborns appears to take an early toll of the heart, affecting its ability to relax and refill with oxygen-rich blood, researchers report. Rat pups separated from their mothers a few hours each day, experienced a significant decrease in this basic heart function when - as life tends to do - an extra stressor was added to raise blood pressure, said Dr. Catalina Bazacliu, neonatologist at the Medical College of Georgia and Children's Hospital of Georgia at Georgia Regents University. Bazacliu worked under the mentorship of Dr...
New Clues To Epstein-Barr Virus
Date: Feb-25-2013Epstein-Barr virus (EBV) affects more than 90 percent of the population worldwide and was the first human virus found to be associated with cancer. Now, researchers from Beth Israel Deaconess Medical Center (BIDMC) have broadened the understanding of this widespread infection with their discovery of a second B-cell attachment receptor for EBV...
