Five months after the implosion of Enron, Feb. 12, 2002, Enron's chief executive, Ken Lay, finally stood in front of Congress and the world and placed his hand on a bible.

At that point everyone had questions for Lay. It was clear by then that Enron was the product of a spectacular ethical failure, that there had been massive cheating and lying. The real question was, how many people had been dishonest? Who was in on it?

She'll still get about $50 million a year in taxpayers' money to run her palaces and travel the world, but there's word from the U.K. that Queen Elizabeth II has had her "pay" frozen until at least 2015.

Hard times, after all, require sacrifices.

Many doctors complain that the few patients who refuse immunizations put all patients at risk, and some refuse them treatment. New York Times Ethicist Ariel Kaminer addresses the question of whether it's ethical for pediatricians to refuse routine care to families with unvaccinated children.

When Freeman Hrabowski became president of The University of Maryland, Baltimore County in 1992, he made it his mission to close the achievement gap. UMBC now sends more African-African students to graduate school in science and technology than any other predominantly white university in the U.S.

Herman Cain quit the presidential primary over the weekend and an Atlanta TV station reports that he may endorse his former rival, Newt Gingrich. NPR's Ken Rudin talks about Cain's decision to quit, and how it will change the primary field.

Teens sharing totally inappropriate naked photos on their phones: Sexting sounded so plausible, it just had to be true.

But now it turns out that's the vast majority of teenagers aren't sexting at all.

The Occupy movement has refocused the national conversation to income inequality. As we've reported in the past, this Tumbler blog puts a face on who the 99 percent are.

But who are the 1 percent?

Today, Gallup released analysis that looked at households who earned more than $500,000 annually and found that in many cases they were a "mirror image" of the 99 percent.

Unmanned aircraft — or drones — are playing a large role in U.S. military operations in Afghanistan but they're starting to show up in increasing numbers in U.S. as well. Drones are already used to patrol the border with Mexico and now they may soon be coming to a police department near you.
