A study published in the Canadian Journal of Physiology and Pharmacology found that rats given regular multivitamin and mineral supplements showed a significantly lower risk of developing colon cancer when they were exposed to carcinogens.... The complex relationship between memory and silence - People who suffer a traumatic experience often don't talk about it, and many forget it over time. But not talking about something doesn't always mean you'll forget it; if you try to force yourself not to think about white bears, soon you'll be imagining polar bears doing the polka. A group of psychological scientists explore the relationship between silence and memories.... Schooling protects refugee children from disease - Refugee children have scant access to medical care and are particularly vulnerable to disease. Fresh research results show that just a few hours of schooling a week may have a pronounced positive impact on their health not only in childhood but later in life when they achieve adulthood.... Placebos and distraction: New study shows how to boost the power of pain relief, without drugs - Placebos reduce pain by creating an expectation of relief. Distraction -- say, doing a puzzle -- relieves it by keeping the brain busy. But do they use the same brain processes? Neuromaging suggests they do. When applying a placebo, scientists see activity in the dorsolateral prefrontal cortex. That's the part of the brain that controls high-level cognitive functions like working memory and attention -- which is what you use to do that distracting puzzle....
