Does Prayer Really Work?

The science behind faith.

  1. On a brilliant February morning in San Francisco, I’m talking to Elisabeth Targ, a psychiatrist with impeccable research credentials who’s conducting studies that disturb some people and fascinate others: the ability of prayer to heal life-threatening disease.
