Blind drunk mice reveal effects of alcohol abuse

Scientists have shed light on why binge drinking impairs the body's healing process after a bone fracture. Researchers at Loyola University Medical Centre exposed one group of mice to alcohol levels equivalent to three times the legal limit for driving. A control group was exposed to equal amounts of salt water. The alcohol-exposed group not only formed less bone, but the bone was also weaker. Their levels of a protein involved in recruiting stem cells to the injury site were significantly lower.

Walking 'reduces breast cancer risk'

Walking just one hour a day can lower the risk of breast cancer, according to a study published in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research. In a study of more than 73,000 post-menopausal women, those who walked for at least seven hours a week had a 14 per cent lower risk. Women who engaged in at least an hour of vigorous physical activity every day had a 25 per cent lower risk.

Grapefruit diet may offer remedy to kidney disease

A grapefruit a day keeps the kidney cysts away? Possibly. A study in the British Journal of Pharmacology has identified a component - naringenin - in citrus fruits that blocks the formation of cysts in patients with polycystic kidney disease. 

The common genetic disorder leads to the loss of kidney function, high blood pressure and the need for dialysis. With few treatments available for the disorder, the finding offers hope for a remedy.
