Washington's 2002 sniper shootings, which killed 10 people, triggered symptoms tied to post-traumatic stress in some area residents, finds a new study from the Centers for Disease Control and Prevention.
Of 1,205 people interviewed by phone about six months after the attacks, 7 percent reported symptoms suggestive of post-traumatic stress; women who lived within five miles of one of the shooting sites were four times likelier to report increased symptoms than women who lived farther away. The study appears in the October edition of the American Journal of Preventive Medicine.

It may take people as little as 100 milliseconds to form an impression of another person -- to decide whether he or she is attractive, trustworthy, competent and likable, according to research published in the journal Psychological Science. That's less time than it takes to form a rational thought. Princeton University researchers drew that conclusion after asking 200 people to make judgments about 66 faces.
