Doubt cast on vitamin D's role against disease

Scientists have cast doubt on the value of vitamin D supplements to protect against diseases such as cancers, diabetes and dementia. Writing in The Lancet Diabetes and Endocrinology, French researchers suggest low vitamin D levels do not cause ill health, although they did not look at bone diseases.

Men and women's brains are 'wired differently'

Men and women's brains are connected in different ways which may explain why the sexes excel at certain tasks, say researchers. A US team at the University of Pennsylvania scanned the brains of nearly 1,000 men, women, boys and girls and found striking differences. Male brains appeared to be wired front to back, with few connections bridging the two hemispheres. In females, the pathways criss-crossed between left and right. These... [read news]
