Yoga reduces stress; now it's known why (7/31/2012)

Researchers at UCLA have shown that practicing a form of yogic meditation for just 12 minutes daily for eight weeks led to a reduction in the biological mechanisms responsible for an increase in the immune system's inflammation response. Inflammation, if constantly activated, can contribute to a multitude of chronic health problems. ...> Full Article


Diets high in salt could deplete calcium in the body (7/30/2012)

The scientific community has always wanted to know why people who eat high-salt diets are prone to developing medical problems such as kidney stones and osteoporosis. Medical researchers at the University of Alberta may have solved this puzzle through their work with animal lab models. ...> Full Article


Hunter-gatherers, Westerners use same amount of energy, contrary to theory (7/27/2012)

Modern lifestyles are generally quite different from those of our hunter-gatherer ancestors, a fact that some claim as the cause of the current rise in global obesity, but new results published July 25 in the open access journal PLoS ONE find that there is no difference between the energy expenditure of modern hunter-gatherers and Westerners, casting doubt on this theory. ...> Full Article


Mind vs. body? Dualist beliefs linked with less concern for healthy behaviors (7/26/2012)

Many people, whether they know it or not, are philosophical dualists. That is, they believe that the brain and the mind are two separate entities. Despite the fact dualist beliefs are found in virtually all human cultures, we know surprisingly little about how these beliefs influence thought and behavior in everyday life. A new research article forthcoming in Psychological Science suggests that espousing a dualist philosophy can have important real-life consequences. ...> Full Article

Are cardiac risk factors linked to less blood flow to the brain? (7/21/2012)

Metabolic syndrome, a term used to describe a combination of risk factors that often lead to heart disease and Type 2 diabetes, seems to be linked to lower blood flow to the brain, according to research by the University of Wisconsin School of Medicine and Public Health. ...> Full Article


Could a larger waistline be a result of too much TV as a child? (7/20/2012)

As a youngster, remember your mother warning you that watching too much television would give you square eyes? That might not be true, but a new study, published today in BioMed Central's open access journal International Journal of Behavioral Nutrition and Physical Activity, has found that the more hours young children spend watching TV, the worse their muscular fitness and the larger their waist size as they approach their teens, with possible consequences for adult health. ...> Full Article


Laser treatment improves appearance in burn scars, study shows (7/19/2012)

In a collaboration among researchers at the University of Cincinnati, Shriners Hospitals for Children -- Cincinnati and Cincinnati Children's Hospital Medical Center, burn and skin specialists have conclusively shown that use of a pulsed-dye laser tool improves the appearance, texture and elasticity of burn scars. The study, published online in the journal Dermatological Surgery, compared the use of the laser and compression therapy on scars against compression therapy alone for pediatric burn patients. ...> Full Article


Want to lose weight? Keep a food journal, don't skip meals and avoid going out to lunch (7/18/2012)

Women who want to lose weight should faithfully keep a food journal, and avoid skipping meals and eating in restaurants -- especially at lunch -- suggests new research from Fred Hutchinson Cancer Research Center. ...> Full Article


In adult humans, brown fat is actually beige (7/16/2012)

The calorie-burning and heat-generating brown fat found in full-grown humans is actually not quite brown; It's beige. So says a new study reported on July 12th in the journal Cell, a Cell Press publication, in which researchers fully characterize this promising obesity-fighting tissue in both mice and humans for the first time. ...> Full Article


Subtle goal reminders, known as primes, can offset hedonic effects of food and facilitate health behavior (7/14/2012)

Research on the non-conscious processes underlying the common difficulties in weight control has shown that palatable food cues can activate reward expectations and a hedonic eating goal, facilitating overeating. These processes are especially prevalent in people struggling with weight regulation. In this talk, I will briefly review how subtle external goal primes can be used to offset these effects and direct motivated behavior toward pursuit of the dieting goal. ...> Full Article

What happens when we sunburn (7/10/2012)

What happens when we sunburnThe biological mechanism of sunburn ? the reddish, painful, protective immune response from ultraviolet (UV) radiation ? is a consequence of RNA damage to skin cells, report researchers at the University of California, San Diego School of Medicine and elsewhere in the July 8, 2012 Advance Online Publication of Nature Medicine. ...> Full Article


Discovery explains how cellular pathways converge to regulate food intake and body weight (7/9/2012)

In the complex chain of molecular events that underlie eating behaviors and body weight, the AMPK enzyme has proven to be a critical link. New research from Beth Israel Deaconess Medical Center further elucidates AMPK's role, and could yield new treatment strategies for both metabolic diseases and cancers. ...> Full Article


Cutting calories might help you live longer, but not without increased physical activity (7/8/2012)

Investigators reporting in the July 3 issue of the Cell Press journal Cell Metabolism have found that in flies, dietary restriction causes enhanced fat metabolism in the muscle and increased physical activity, both of which are critical for extending lifespan. The findings suggest that dietary restriction may cause changes in muscle that can lead to a more active and longer life. ...> Full Article


Sleep deprivation effect on the immune system mirrors physical stress (7/7/2012)

Severe sleep loss jolts the immune system into action, reflecting the same type of immediate response shown during exposure to stress, a new study reports. Researchers in the Netherlands and United Kingdom compared the white blood cell counts of 15 healthy young men under normal and severely sleep-deprived conditions. The greatest changes were seen in the white blood cells known as granulocytes, which showed a loss of day-night rhythmicity, along with increased numbers, particularly at night. ...> Full Article


Preventing the immune system from going haywire during sepsis (7/6/2012)

Many strategies aiming at holding back the extreme response of the immune system during sepsis have been developed but little progress has been made. A new study shows that a drug known as RC-3095 attenuates the release of exacerbating immune response elements in patients with sepsis and limits the spread of infection in sepsis animal models, indicating the potential of RC-3095 in preventing sepsis-induced multiple organ dysfunctions. ...> Full Article


Researchers discover potential explanation for why a diet high in DHA improves memory (7/5/2012)

Study challenges the notion that a calorie is just a calorie (7/4/2012)

A new study published in the Journal of American Medical Association challenges the notion that "a calorie is a calorie." The study, led by Cara Ebbeling, Ph.D., associate director and David Ludwig, M.D., director of the New Balance Foundation Obesity Prevention Center Boston Children's Hospital, finds diets that reduce the surge in blood sugar after a meal -- either low-glycemic index or very-low carbohydrate -- may be preferable to a low-fat diet for those trying to achieve lasting weight loss. ...> Full Article


Necrosis after cortisone injections (7/4/2012)

Boosting blood system protein complex protects against radiation toxicity (7/3/2012)

New research in Nature Medicine shows that boosting a protein pathway in the body's blood making system protects mice from otherwise fatal radiation poisoning. Scientists in the multi-institutional study -- posted online by the journal on June 24 -- say their findings open the potential for new treatments against radiation toxicity during cancer treatment or environmental exposures -- such as in a nuclear explosion or accident. ...> Full Article

Is arm length the reason women need reading glasses sooner than men? (7/1/2012)

Studies have consistently reported that women require reading glasses or bifocal lenses earlier than men. According to a recent Investigative Ophthalmology & Visual Science paper, the gender difference is caused by factors other than focusing ability, such as arm length or preferred reading distance, which should be considered when prescribing readers or bifocals. ...> Full Article
