Critical molecules for hearing and balance discovered (11/29/2011)

Researchers have found long-sought genes in the sensory hair cells of the inner ear that, when mutated, prevent sound waves from being converted to electric signals -- a fundamental first step in hearing. The team, co-led by Jeffrey Holt, Ph.D., in the department of otolaryngology at Children's Hospital Boston, and Andrew Griffith, MD, Ph.D., of the NIH's National Institute on Deafness and other Communication Disorders (NIDCD), then restored these electrical signals in the sensory cells of deaf mice by introducing normal genes. ...> Full Article

As probiotics use grows for gut health, VSL3 has designations for specific GI issues (11/28/2011)

A growing US market for probiotics indicates that the healthcare community and consumers recognize the value of these beneficial microorganisms for intestinal health. As the category matures, however, one probiotic preparation -- VSL#3 -- stands apart and ahead because it has been classified as a refrigerated medical food designated for the dietary management of three specific GI conditions: Ulcerative Colitis, Ileal Pouch and Irritable Bowel Syndrome (IBS). ...> Full Article


The scoop on the dangers of snow shoveling (11/27/2011)

Urban legend warns shoveling snow causes heart attacks, and the legend seems all too accurate, especially for male wintery excavators with a family history of premature cardiovascular disease. However, until recently this warning was based on anecdotal reports. Two of the most important cardiology associations in the US include snow -shoveling on their websites as a high risk physical activity, but all the citation references indicate that this warning was based one or two incidents. ...> Full Article


Probiotic protects intestine from radiation injury (11/27/2011)

Probiotic protects intestine from radiation injuryScientists at Washington University School of Medicine in St. Louis have shown that taking a probiotic before radiation therapy can protect the intestine from damage -- at least in mice.

A component of garlic oil may help release protective compounds to the heart after heart attack, during cardiac surgery, or as a treatment for heart failure. ...> Full Article


Female marathoners have less plaque than male counterparts, sedentary women (11/21/2011)

While elite female marathon runners have fewer coronary plaques than their sedentary counterparts, they developed the same plaque volume and percent stenosis when it occurs, according to study findings presented Nov. 14 at the at the American Heart Association scientific sessions in Orlando, Fla. This differs from their counterpart elite male runners who developed significantly more plaque volume than their sedentary counterparts. ...> Full Article


Enzyme boosts metabolism, prevents weight gain in mice (11/20/2011)

Male and female mice engineered to express the inflammatory enzyme IKKbeta in their fat tissue ate more but gained less weight. They burned sugar and fat more effectively than mice who were left unaltered. The research may shed light on how obesity and inflammation affect insulin resistance and sensitivity. ...> Full Article


More fiber, but not necessarily less fat, good for teen diets (11/19/2011)

A diet high in fiber - but not necessarily one low in saturated fat or cholesterol - is tied to a lower risk of heart disease and type-2 diabetes in teenagers, according to new findings from Michigan State University. ...> Full Article

No need to shrink guts to have a larger brain (11/17/2011)

The so-called expensive-tissue hypothesis, which suggests a trade-off between the size of the brain and the size of the digestive tract, has been challenged by researchers at the University of Zurich. They have shown that brains in mammals have grown over the course of evolution without the digestive organs having to become smaller. ...> Full Article


Researcher provides further evidence that slow eating reduces food intake (11/16/2011)

Two new studies are providing additional insights into the role that eating rate plays in the amount of food one consumes. The studies found that men eat significantly faster than women, heavier people eat faster than slimmer people, and refined grains are consumed faster than whole grains, among other findings. ...> Full Article


Benefits of working from home depends on family demands (11/15/2011)

If you work from home part of the week as a teleworker, does it help reduce work exhaustion caused by juggling work and family commitments? The answer may depend on the level of conflict you have between work and home and your ability to recharge your batteries adequately, according to Professor Timothy Golden, from the Rensselaer Polytechnic Institute in Troy, NY. His work is published online in Springer's Journal of Business and Psychology. ...> Full Article


Why cooking counts (11/14/2011)

In a first-of-its kind study, Harvard researchers have shown that cooked meat provides more energy than raw meat, a finding that suggests humans are biologically adapted to take advantage of the benefits of cooking, and that cooking played a key role in driving the evolution of man from an ape-like creature into one more closely resembling modern humans. ...> Full Article


Vegetarian diet, physical activity protect against diabetes in black population, study shows (11/13/2011)

A vegetarian diet and regular exercise significantly reduced the risk of diabetes in African Americans, who are twice as likely to be diagnosed with diabetes as non-Hispanic whites. Compared to non-vegetarian blacks, vegan blacks had a 70 percent reduced risk of diabetes, and lacto-ovo vegetarian blacks a 53 percent reduced risk. Exercising three or more times a week, compared to once a week or never, showed a 35 percent reduced risk of diabetes. ...> Full Article


Skin 'sees' UV light, starts producing pigment (11/12/2011)

In a new study, biologists report that melanocyte skin cells detect ultraviolet light using a photosensitive receptor previously thought to exist only in the eye. This eye-like ability of skin to sense light triggers the production of melanin within hours, more quickly than previously thought, in an apparent rush to protect against damage to DNA. ...> Full Article


Exercise provides clue to deadly ataxia (11/11/2011)

When Dr. John Fryer and Dr. Huda Zoghbi prescribed mild exercise for mice with a neurodegenerative disorder called spinocerebellar ataxia 1, they did not know what to expect. What they found was the mice that exercised lived longer than those that had not. A report on their research appears online today in the journal Science. ...> Full Article


Caucasians who avoid sun exposure more likely to be vitamin D deficient, Stanford study suggests (11/10/2011)

Light-skinned people who avoid the sun are twice as likely to suffer from vitamin D deficiency as those who do not, according to a study of nearly 6,000 people by researchers at the Stanford University School of Medicine. Surprisingly, the use of sunscreen did not significantly affect blood levels of vitamin D, perhaps because users were applying too little or too infrequently, the researchers speculate. ...> Full Article

Trance stare led researchers to discover a genuine hypnotic state (11/7/2011)

An international team of researchers have found the existence of a genuine hypnotic state. The researchers studied the 'trance stare', a glazed look in the eyes that has often been associated with hypnosis in the popular culture but rarely studied scientifically. These findings have major implications for psychology and neurosciences, as they confirm the existence of a novel mental state in humans. ...> Full Article


More power to the cranberry: Study shows juice better than extracts at fighting infections (11/6/2011)

More power to the cranberry: Study shows juice better than extracts at fighting infectionsWith scientific evidence now supporting the age-old wisdom that cranberries prevent urinary tract infections, people have wondered if proanthocyanidins or PACs, a group of flavonoids found in cranberries, if extracted and condensed, perhaps in pill form, would be as effective as drinking the juice or eating cranberry sauce. A new study from researchers at Worcester Polytechnic shows that the juice is far better at preventing biofilm formation, the precursor of infection, than PACs alone. ...> Full Article
