Neuroscientists Study Effects of Viewing Violence
Watching violence lowers activity in areas of the brain that suppress aggressive behavior, shows new research from Columbia University. Using fMRIs while experiment subjects watched violent scenes, scientists observed quickly diminished activity and interconnectedness in the frontolimbic network of the brain. With repeated viewings of violence, the supplementary motor cortex, an area of the brain associated with planning were activated. These results did not occur when subjects watched scenes of horror or physical activity, suggesting that viewing violent media may increase viewer aggression by inhibiting normal suppression and activating action-planning in the brain.

Close Families Raise Independent Children
Research on young adults aged 23 to 27 shows that those who regularly interact and spend time with their parents lead more independent lives than those who don't. These individuals were more likely to be financially self-sufficient, have a stable relationship and make independent choices. Meanwhile distant children were more likely follow a rebellious, but still dependent, pattern of decision-making.

Depression Treatment Extends Lives of Older Adults with Diabetes
Older diabetics with depression who receive mental health care have lower mortality rates than those who do not, shows a study of 584 patients ranging in age from 60 to 94. Subjects were randomly assigned to either normal care or depression intervention and therapy. At a five-year follow-up, fewer patients who had received depression care had died. Researchers suggest this is because depression may affect an individual's ability to stick to a proper diet and take medication properly.
