Six weeks after revealing she has breast cancer, E! News host Giuliana Rancic says she will have a double mastectomy. The 37-year-old made the announcement Monday on NBC's "Today" show.

Two women in their 80s put the Transportation Security Administration on the defensive this week by going public about their embarrassment during screenings in a private room at Kennedy Airport.

More than three decades after launching, NASA's workhorse spacecraft is inching closer to leaving the solar system behind.

Currently 11 billion miles away from the sun, Voyager 1 has been exploring the fringes of the solar system since 2004. Scientists said Monday the spacecraft has entered a new region in the solar system that they have dubbed the "stagnation zone."

A United Nations-appointed expert is urging Vietnam's government to close down rehabilitation centers for drug users and sex workers following criticism of abuses by an international rights group, calling them "counterproductive."

But the new figures are certain to become a sensitive issue in Britain, as tough economic times and bleak forecasts for the future raise questions about the wisdom of hosting the Olympics.

Scientists have found the biggest black holes known to exist — each one 10 billion times the size of our sun.

A team led by an astronomer at the University of California at Berkeley discovered the two gigantic black holes in clusters of galaxies 300 million light years away. That's relatively close on the galactic scale.

Clarence Pfundheller was standing in front of his locker on the USS Maryland when a fellow sailor told him they were being bombed by Japanese planes.

"We never did call him a liar but he could stretch the truth pretty good," Pfundheller said. "But once you seen him, you knew he wasn't lying."

South Korea says it has decided to resume sending aid to North Korea through the U.N. children's agency UNICEF.
