Time and time again, it has been documented that regular exercise has many health benefits including lowering risks associated with the comorbidities of obesity. With only 30% of Americans trying to lose weight meeting the National Institutes of Health exercise guidelines of 300 minutes/week, a study in the January/February 2010 issue of the Journal of Nutrition Education and Behavior explores the paradox that exists -an antidote for obesity and its comorbidities is exercise, but the majority of obese Americans do not exercise. Investigators explore and compare the barriers associated with regular exercise in health clubs between overweight and normal weight individuals. http://www.physorg.com/news180277240.html Medicine & Health Thu, 17 Dec 2009 13:10:07 EST news180277240 Overseas development charities are highly dependent on donations from individuals. In this new study, researchers from the Universities of Southampton, Oxford and Cass Business School examined how the level of donations to overseas development charities has changed over time, what kind of people give money to such charities and their reasons for giving, and how government policy affects people's willingness to donate. http://www.physorg.com/news179932602.html Other Sciences Sun, 13 Dec 2009 13:17:21 EST news179932602 (PhysOrg.com) -- Visually impaired people appear to be fearless, navigating busy sidewalks and crosswalks, safely finding their way using nothing more than a cane as a guide. The reason they can do this, researchers suggest, is that in at least some circumstances, blindness can heighten other senses, helping individuals adapt. http://www.physorg.com/news177773741.html Medicine & Health Wed, 18 Nov 2009 14:20:04 EST news177773741 Research carried out among thousands of people has shown a clear connection between depression and a loss of bone mass, leading to osteoporosis and fractures. http://www.physorg.com/news177000565.html Medicine & Health Mon, 09 Nov 2009 14:51:41 EST news177000565 Veterans classified as superobese and those with a higher chronic disease burden appear more likely to die within a year of having bariatric surgery, according to a report in the October issue of Archives of Surgery. http://www.physorg.com/news175192092.html Medicine & Health Mon, 19 Oct 2009 20:30:01 EST news175192092 A new study from the Trudeau Institute in Saranac Lake, New York, demonstrates that immune system cells important for both pathogen resistance and vaccine efficacy live longer in older animals but because of this longevity acquire functional defects. The work may provide new targets for boosting immune system function in older individuals. http://www.physorg.com/news173975148.html Medicine & Health Mon, 05 Oct 2009 15:26:52 EST news173975148 Researchers from the University of Sydney, Australia determined that patients with a sedentary lifestyle who engage in routine physical activities lower their risk of nonalcoholic fatty liver disease (NAFLD). The lower risk of problems associated with fatty liver was not contingent upon weight loss, but a direct result from the increased aerobic exercise. The results of this study are published in the October issue of Hepatology, a journal of the American Association for the Study of Liver Diseases. http://www.physorg.com/news171731410.html Medicine & Health Wed, 09 Sep 2009 16:10:49 EST news171731410 Nerve fibers that link perception and motor regions of the brain are disconnected in tone-deaf people, according to new research in the August 19 issue of The Journal of Neuroscience. Experts estimate that at least 10 percent of the population may be tone deaf - unable to sing in tune.

The results of this study highlight the need for further research into the effects of weight loss in individuals suffering from psychiatric disorders. http://www.physorg.com/news167907081.html Medicine & Health Mon, 27 Jul 2009 09:51:46 EST news167907081 Mice lacking the fat hormone leptin or the ability to respond to it become morbidly obese and severely diabetic -not to mention downright sluggish. Now, a new study in the June Cell Metabolism shows that blood sugar control in those animals can be completely restored by returning leptin sensitivity to a single class of neurons in the brain, which account for only a small fraction of those that normally carry the hormone receptors. http://www.physorg.com/news163164889.html Biology Tue, 02 Jun 2009 12:36:37 EST news163164889 A new study appearing in Clinical Cardiology examines the average fitness level of the morbidly obese (body mass indexes between 40.0 and 49.9). The findings show that the tested population was sedentary for more than 99 percent of the day and, on average, walked less than 2,500 steps per day - far below healthy living guidelines of 10,000 steps per day. The results provide important links between obesity, poor fitness and cardiovascular disease. http://www.physorg.com/news157219241.html Medicine & Health Wed, 25 Mar 2009 17:01:30 EST news157219241 (PhysOrg.com) -- A University of Arizona research team recently completed a study looking at the DNA blueprint of almost 1,000 individuals and comparing that to detailed measurements of their hair, skin and eye color. http://www.physorg.com/news155239299.html Chemistry Mon, 02 Mar 2009 18:03:01 EST news155239299 The Declaration of Independence may proclaim that all men are created equal, but American whites tend to distribute their prejudice unequally toward certain members of minority groups, according to new research. http://www.physorg.com/news154791355.html Other Sciences Wed, 25 Feb 2009 13:36:58 EST news154791355 Dr. Marcia Blackman and her research team at the Trudeau Institute have followed up on an intriguing report published in the journal Nature in May 2007 by Dr. Herbert Virgin, et al., showing that mice persistently infected with certain forms of herpesvirus, which can establish lifelong latent infections, are resistant to infection with bacterial pathogens. http://www.physorg.com/news153669519.html Medicine & Health Thu, 12 Feb 2009 13:59:12 EST news153669519 (GPEARI, Portugal) -- Cooperation, despite being now considered the third force of evolution, just behind mutation and natural selection, is difficult to explain in the context of an evolutionary process based on competition between individuals and selfish behaviour. But this puzzle, that has haunted scientists for decades, is now a little closer to be solved by research about to be published in the journal Physical Review Letters. http://www.physorg.com/news153150016.html Physics Fri, 06 Feb 2009 13:40:49 EST news153150016 "Conventional wisdom - and conventional theory - tells us that when infection can potentially be spread to almost everyone in a community, such as for measles, a disease outbreak can never be contained using voluntary vaccination," says Chris Bauch and Ana Persic, researchers from the University of Guelph. "However, our work shows conventional wisdom may be wrong for diseases that are spread primarily through close contact, such as smallpox." Their findings appear in the open-access journal PLoS Computational Biology on February 6th. http://www.physorg.com/news153145959.html Biology Fri, 06 Feb 2009 12:33:05 EST news153145959 A new study published in Value in Health reviews the economic burden of migraine in the U.S. and recent clinical findings of the health risks of this neurological condition.

Though only 7 percent of the U.S. population has diabetes, in a study of data from 2005, nearly 22 percent ($171 billion dollars) of hospital charges resulted from treating individuals with the condition. http://www.physorg.com/news151077389.html Medicine & Health Tue, 13 Jan 2009 13:56:29 EST news151077389 Facial expressions of emotion are hardwired into our genes, according to a study published today in the Journal of Personality and Social Psychology.
