Researchers in Illinois and Singapore have found that the aging brain reflects cultural differences in the way that it processes visual information. This study appears this month in the journal Cognitive, Affective & Behavioral Neuroscience. This paper and another published by the same group in 2006 are the first to demonstrate that culture can alter the brain?s perceptive mechanisms.
Contrary to popular opinion, children play a key role in strengthening local communities and making people feel safe in their neighbourhoods, according to a study funded by the Economic and Social Research Council (ESRC).
Being obese increases the risk of breast cancer in post-menopausal women, shortens the time between return of the disease and lowers overall survival rates. Italian researchers speaking at Experimental Biology 2007 in Washington, DC, now report evidence on how leptin, a hormone found in fat cells, significantly influences breast cancer development and progression in mice.
Using breast cancer cells, researchers have demonstrated that cancer phenotype can be reversibly altered by manipulations other than genetic means.
The culture of a school can dampen — or exacerbate — the violent or disruptive tendencies of aggressive young teens, new research indicates. A large-scale study from the University of Illinois found that while personal traits and peer interactions have the most direct effect on the aggressive behavior of middle school students, the school environment also influences student aggression.

Chemicals in cruciferous vegetables, such as broccoli, watercress, cabbage and cauliflower, appear to not only stop human prostate cancer cells from growing in mice but also may cut off the formation of blood vessels that “feed” tumors, says a University of Pittsburgh Cancer Institute study.
