The tough economy has taken its toll on most states, putting budgets deep in the red and putting people out of work.

But North Dakota has a low 3.5 percent unemployment rate and a state budget with a billion dollar surplus. That's because of a major oil boom in the western part of the state, a discovery of at least 2 billion barrels to be gained by fracking — the controversial process of injecting fluid deep into underground rock formations to force the oil out.

Chris Whitney lived in San Francisco in the 1980s, when there wasn't much known about AIDS. But then he tested positive for HIV in 1985. He explains what happened next to his frien Erin Kuka.

"The first person I told was the person I was dating at the time, and that was pretty much the last conversation I had with him," Whitney says. "You know, the fear just took over. That kind of made me really wary about opening up to people.

AIDS activists haven't always been happy with Barack Obama. But many of them were on this Worlds AIDS Day.

A Pew Hispanic Center study released today finds that two-thirds of undocumented immigrants in the United States have lived in the country for more than 10 years. The study also found that 46 percent of undocumented immigrants had minor children.

In its press release, Pew says this research is important because it comes on the heels of a hot debate on immigration during the Republican presidential debates.

Children in foster care are significantly more likely than other kids to be given mind-altering drugs, according to a study of five states released Thursday by the Government Accountability Office.

The report, which focused on children in the Medicaid program, also found that foster kids were more likely to be prescribed five or more psychotropic drugs at an age and at doses that exceed the maximum FDA-approved levels — both of which carry serious health risks.

This is just a guess, but the single part of America's food system that inspires the most horrified fascination is probably the slaughterhouse. One reason may be that these factories that turn cattle, hogs and chickens into packaged meat are generally off-limits to the public and photographers.
