Video games can be more than brain candy. Mounting evidence suggests that keeping the brain active can keep it healthy—staving off the effects of Alzheimer's disease in the elderly, counteracting ADHD in the young, and enhancing memory, attention, and motor skills for everyone in between. As researchers debate how well shoot-'em-up or Sudoku skills carry over to other tasks, multiple companies rush to cash in on the hype.

All men may be created equal, but our brains don't believe it. Two Princeton University researchers examined the brain activity of 24 people as they viewed photographs of various social groups. It turns out we stereotype the elderly and disabled as "high warmth, low competence," which inspires pity, but nonetheless activates a "social" part of the brain we use to think about people. Photos of homeless people and drug addicts, on the other hand, activate regions associated with disgust instead. Our brains barely register these outcasts as human.
