Fortunately, scientists have made great strides in sorting out the underlying causes of depression: it is almost certainly a defect in some combination of key genes, plus the right triggering environment. And researchers are well along in developing some promising therapies, pharmacological and otherwise, to supplement what is already available...
Last summer, though, scientists at the University of Wisconsin reported on a long-term study of 400 boys that had been going on for more than a quarter-century. The scientists had collected DNA from the boys and recorded their behavior at regular intervals. As with the earlier research, scientists...
What could possibly turn kids this young into brutal killers? The recipe for violence is almost certainly a mix of bad genes and a bad environment, and the evidence is strong that the recipe is cooked up very early in life. Until about a decade ago, most experts assumed that...
The finding thrilled some scientists--here, finally, was an explanation for criminality--and appalled others, who feared that if genes dictate behavior, it could lead to genetic typecasting of entire races. But lots of violent men don't have the defective gene, while many noncriminals do. Here, too, the simple...
But this study is hardly the last word on the genetic roots of violence. There are almost certainly other genes involved and other kinds of life stress that can contribute to violence. Moffitt and her colleagues are already planning more experiments to isolate other factors that might be involved. As...
