A disease that once ravaged the world, killed countless children, even famously affected President Franklin Roosevelt, has now been eradicated in all but three countries: Nigeria, Pakistan and Afghanistan. The disease is polio. And at the United Nations last week, Secretary General Ban Ki-Moon met leaders of those three countries, who pledged to step up efforts to wipe out polio entirely.
Thousands of people gathered at the New York Hall of Science this weekend for what's called the World Maker Faire. It was the third an annual celebration of 21st century Do-It-Yourself culture, with workshops, speakers and demonstrations.
But, as reporter Stan Alcorn discovered, the main attraction is the makers themselves.
STAN ALCORN, BYLINE: At the center of the World Maker Faire is Katy Perry.
JESSE GREEN: Katy Perry is the unicorn that we made for a friend's wedding.
The role of James Bond has been played by six different actors in the Bond film franchise that started in 1962. Each actor brought his own strengths to the rakish British spy, from brooding physicality (Sean Connery, Daniel Craig) to smooth charm (Roger Moore, Pierce Brosnan).
For every actor who has portrayed Bond, there are fans who think he defined the character, and that the others merely toiled in his shadow. Craig will try to solidify his place in the Bond pantheon next month when the franchise releases its 23rd film, Skyfall.
