Petitions have been a common form of protest throughout modern history, at times bringing attention to causes through little more than handwritten letters and word of mouth.

But like a lot of other things, petitions are going viral. And one website in particular has contributed to the phenomenon.

Change.org offers tools to let individuals start their own online campaigns, a way to bring instant awareness to issues that range from the environment to human rights.

The Defense Department is bracing for billions of dollars in budget cuts — and that has defense contractors looking for new markets. Homeland Security is one of the most promising, particularly border security, which hasn't suffered any big cuts. So companies are lining up in hopes of landing a contract.

At a border security trade show in Phoenix, Ariz., there's enough surveillance equipment on the floor of the convention center to spot a federal appropriation from 5 miles away.

Real estate is about location, location, location. And foreclosure is no different. Depending on the state, it can take an average of three months or three years to process a foreclosure. And the disparity in how states deal with foreclosures is getting bigger.

The fate of thousands of troubled homeowners in Central Florida rests in the hands of Lee Haworth, foreclosure administrative judge for Florida's 12th Judicial Circuit. "We were hit pretty hard," Haworth says.

Last February, a group of young people were arrested for spray-painting graffiti on the walls of their school in the southern Syrian city of Daraa. They were beaten and interrogated. A year ago this Sunday, people went out to protest those arrests. And so began the Syrian uprising — an uprising that in some parts of Syria has turned into an armed insurgency and seen government troops respond with untold brutality. In all, thousands of people have died, with no clear end in sight.

One night in 1995 completely reshaped the lives of Phil and Laura Donney. Their parents were arguing, and their father stabbed their mother, killing her. Phil was 7; his sister was 4.

Ken Donney was sent to prison, and the children went to live with their mother's sisters.

Phil, 23, recently sat down with his aunt, Abby Leibman, the twin sister of his mother, Nina Leibman.

"What was it like becoming a parent to my sister and I overnight?" Phil asks.

An extraordinary special investigation by a federal judge has concluded that two Justice Department prosecutors intentionally hid evidence in the case against Sen. Ted Stevens, one of the biggest political corruption cases in recent history.

A blistering report released Thursday found that the government team concealed documents that would have helped the late Stevens, a longtime Republican senator from Alaska, defend himself against false-statements charges in 2008. Stevens lost his Senate seat as the scandal played out, and he died in a plane crash two years later.

Shell Oil Co. has chosen a site near Pittsburgh for a major, multibillion-dollar petrochemical refinery that could provide a huge economic boost to the region.

Dan Carlson, Shell's general manager of new business development, said Thursday that the company signed a land option agreement with Horsehead Corp. to evaluate a site near Monaca, about 35 miles northwest of Pittsburgh.

Early on Thursday, lawmakers in New York approved a bill that will make the state the first to require DNA samples from almost all convicted criminals — and make its DNA database one of the largest in the nation.

For perhaps the first time in recent history, male reproductive health is at the forefront of political debate.

In at least six states, lawmakers — all women and all Democrats — have proposed bills or amendments in the last few weeks that aim to regulate a man's access to reproductive health care. It's their way of responding to the ongoing debate around contraception and abortion, said Jennifer Lawless, director of the Women & Politics Institute at American University.

Giant and colossal squids can be more than 40 feet long, if you measure all the way out to the tip of their two long feeding tentacles. But it's their eyes that are truly huge — the size of basketballs.

Now, scientists say these squids may have the biggest eyes in the animal kingdom because they need to detect a major predator, the sperm whale, as it moves toward them through the underwater darkness.

A telescope in Arizona has taken some of the clearest pictures ever of distant celestial objects, including the first images of the innermost planet in a planetary system 127 light years from Earth. They achieved this astronomical tour de force using something called adaptive optics, a technique that eliminates the blurring caused by the Earth's atmosphere.

If you're trying to escape the turmoil in Syria for the calm in Jordan, you have two choices.

You can go the legal way. Just get in a car and try to drive across the border. But that's not very easy these days. The Syrian government isn't letting many people out.

Or you can try the illegal way. Wait until nightfall, climb through a barbed-wire fence. It sounds dodgy, but if you make it over, you'll actually be welcomed by the Jordanian army. Troops will take your name, give you a drink of water, let you rest.

Voting along party lines, the Marion County Election Board decided that Richard Lugar, the Republican senator from Indiana, was ineligible to vote in his home precinct.

The Indianapolis Star reports that the board agreed with its staff attorney that according to state law Lugar had abandoned his residency when he sold his house and moved to the Washington area.

Mitt Romney and the superPAC supporting him spent more than 15 times as much as Rick Santorum and the superPAC backing him on television ads in Alabama and Mississippi, according to an NPR analysis of data collected by Kantar Media's CMAG unit and reported by the Washington Post.

Santorum won both primaries on Tuesday; Romney finished third in both states.

"Researchers from the University of Rochester and North Carolina State University have for the first time sent a message using a beam of neutrinos — nearly massless particles that travel at almost the speed of light," U of R reports.

And they pushed the message — which simply spelled out the world "Neutrino" — through "240 meters of stone" (787 feet).

Who better to introduce the true sound of Portland, Ore. than the man behind many of its best musical acts?

Chinese cartoonists have used the Internet in recent years to take aim at the Communist Party. Using Twitter-like microblogs, they try to slip past censors and skewer their government in ways that would have been unthinkable a generation ago.

One of their targets this month is an old-fashioned Communist propaganda campaign extolling the virtues of Lei Feng, a model People's Liberation Army soldier who was devoted to his fellow workers and China's leaders — and who has been dead for half a century.
