Researchers at the Sahlgrenska Academy have identified the genetic variations that are believed to cause osteoporosis. The study, published in Nature Genetics and involving leading researchers from Sweden and the world, shows among other interesting facts that women with a higher proportion of genetic variations associated with osteoporosis have a more than 50 percent increased fracture risk.

A team of Japanese researchers revealed study results at the Experimental Biology 2012 meeting that show how acupuncture therapy mitigates skeletal muscle loss and holds promise for those seeking improved mobility through muscle rejuvenation.

Cognitive decline is a pressing global health care issue. Worldwide, one case of dementia is detected every seven seconds. Mild cognitive impairment is a well recognized risk factor for dementia, and represents a critical window of opportunity for intervening and altering the trajectory of cognitive decline in seniors.

Researchers have identified key genes that switch off with aging, highlighting them as potential targets for anti-aging therapies. Researchers at King's College London, in collaboration with the Wellcome Trust Sanger Institute, have identified a group of 'aging' genes that are switched on and off by natural mechanisms called epigenetic factors, influencing the rate of healthy aging and potential longevity.

'Brain freeze' is a nearly universal experience -- almost everyone has felt the near-instantaneous headache brought on by a bite of ice cream or slurp of ice-cold soda on the upper palate. However, scientists are still at a loss to explain this phenomenon. Since migraine sufferers are more likely to experience brain freeze than people who don't have this often-debilitating condition, brain freeze may share a common mechanism with other types of headaches, including those brought on by the trauma of blast-related combat injuries in soldiers.

Researchers from Cleveland Clinic's Wellness Institute and Harvard University have found that greater consumption of sugar-sweetened and low-calorie sodas is associated with a higher risk of stroke. Conversely, consumption of caffeinated or decaffeinated coffee was associated with a lower risk.

In contrasting China and America, pundits often cite our free and independent media as one of our greatest strengths, together with the tremendous importance which our society places upon individual American lives. For us, a single wrongful death can sometimes provoke weeks of massive media coverage and galvanize the nation into corrective action, while life remains cheap in China, a far poorer land of over a billion people, ruled by a ruthless Communist Party eager to bury its mistakes. But an examination of two of the greatest public-health scandals of the last few years casts serious doubt on this widespread belief.

The culprit behind a failed hip or knee replacements might be found in the mouth. DNA testing of bacteria from the fluid that lubricates hip and knee joints had bacteria with the same DNA as the plaque from patients with gum disease and in need of a joint replacement.

At a time when obesity has become epidemic in American society, Dartmouth scientists have found that functional magnetic resonance imaging (fMRI) brain scans may be able to predict weight gain. In a study published April 18, 2012, in The Journal of Neuroscience, the researchers demonstrated a connection between fMRI brain responses to appetite-driven cues and future behavior.

Research group headed by Professor Takashi Tsuji demonstrates regenerating "functional hair regeneration from adult stem cells" Substantial advance in the development of next-generation of "organ replacement regenerative therapies"
