Republican presidential candidates (from left) Jon Huntsman, Herman Cain, Rep. Michele Bachmann, Mitt Romney, Gov. Rick Perry, Rep. Ron Paul, Newt Gingrich and Rick Santorum prepare to debate during the event sponsored by CNN and the Tea Party Express at the Florida state fairgrounds on Sept. 12 in Tampa.
It was one year ago that the Tea Party movement helped Republicans take control of the U.S. House of Representatives. With the presidential election a year away, the movement finds itself searching for ways to have the same kind of impact this time around.
The Tea Party celebrated on election night last year with candidates like Rand Paul, who captured a Senate seat in Kentucky.
"Tonight there's a Tea Party tidal wave, and we're sending a message to them," Paul said in his victory speech.
The sudden bankruptcy of commodities trading firm MF Global has thrust a familiar name in to the spotlight: Jon Corzine. Previously, Corzine was governor of New Jersey, a U.S. senator and chairman and CEO of the investment firm Goldman Sachs. Corzine resigned last week as chairman and CEO of MF Global as investigators search for hundreds of millions of dollars missing from clients' accounts.
Some Oregon residents are voting in a special primary Tuesday to replace a U.S. representative who resigned after a scandal. To try to make voting more accessible, election workers are taking iPads to places like nursing homes and community centers. Voters will be able to enlarge the font size, tap their selection and print out a completed ballot.
NASA's next Mars rover, Curiosity, seen in this artist's rendering, will use 8 pounds of plutonium-238 as its power supply. That's a significant portion of the remaining space fuel. NASA and the Department of Energy have offered to split the costs of producing the fuel, but Congress has so far opposed that arrangement.
NASA's Voyager spacecraft, seen in this artist's rendering, runs on plutonium-238. It's the farthest man-made object from Earth NASA has ever sent out.
When NASA's next Mars rover blasts off later this month, the car-sized robot will carry with it nearly eight pounds of a special kind of plutonium fuel that's in short supply.
NASA has relied on that fuel, called plutonium-238, to power robotic missions for five decades.
But with supplies running low, scientists who want the government to make more are finding that it sometimes seems easier to chart a course across the solar system than to navigate the budget process inside Washington, D.C.
From Los Angeles to New York City and Miami to Dallas, professional basketball fans face November without the NBA. The league keeps canceling games because of the ongoing lockout as players and owners squabble over future contracts.
Most NBA cities have other professional sports to turn to with hoops on hiatus. But some markets, like downtown Oklahoma City, only have one game in town.

Copernicus' heliocentric theory, which said Earth and the other planets revolve around the sun, ran counter to the Bible and astronomy texts of the day. Published in 1543, his ideas were taught in the 16th century but were "immediately dismissed as absurd," says science historian Robert Westman.
It doesn't happen often, but there are times when a single book turns the world on its head. Isaac Newton's Principia unraveled the mystery of gravity. Charles Darwin's On the Origin of Species explained how evolution worked.
But before either of these, there was On the Revolutions of the Heavenly Spheres by Nicolaus Copernicus. It was published in 1543. In it, Copernicus made the astounding claim that Earth revolves around the sun, not the other way around.
The U.S. Supreme Court, an institution steeped in tradition, steps into the turbulent world of new technology Tuesday. At issue before the court is whether police must get a warrant from a judge before they can attach a GPS tracking device to a car so they can monitor a suspect's every movement for an indefinite period of time.
The case could have enormous implications for privacy rights in the information age.

Of Art And Nature: A model shows one of the three ponds that will surround Crystal Bridges. The museum got its name from the two galleries that will actually serve as bridges over the ponds. Architect Moshe Safdie says his design is meant to help blend the experience of the museum's art with that of its natural surroundings.
The American art world's biggest event in decades is happening this week — but it's not where you'd expect it to be.
Bentonville, Ark. is home to Wal-Mart headquarters and, starting Nov. 11, it will also be home to the Crystal Bridges Museum of American Art, and what some critics are calling one of the world's best collections of American art.
David Horcajada fishes a beer can out of his backpack at a Madrid square.
"Five years ago, believe me, there were really few people drinking on the streets," he says. "Right now, everybody is drinking on the street because people cannot afford to pay for drinks at bars. So since we're Spanish and we do drink, we party a lot, so it doesn't matter if we don't have money. We'll keep doing it."
A frame grab from a video posted on YouTube on November 4, shows two young boys sitting next to the body of a dead man identified as Yahya Hamad from Baba Amer neighborhood in Homs, where a rights watchdog has said that several victims were killed by Syrian security forces despite a Damascus pledge to withdraw forces from protest hubs.
More than 100 protesters have been killed in the past five days in clashes with government forces, Syrian activists said. Despite a ceasefire agreement with Arab League and despite protests from international governments, Bashar Asad's regime has continued its relentless assault against the opposition.
