Two Americans have won the 2012 Nobel Prize in Chemistry. Robert Lefkowitz and Brian Koblika were awarded the prize for their work on protein receptors that tell cells what's going on around the human body. Their research has allowed drug makers to develop medication with fewer side effects. The pair with share the $1.2 million award.

Canada is not used to high profile spy cases. But today there is news that the country has tried its first successful case using the Security of Information Act. And it's quite the case.

The CBC reports that a Navy sub lieutenant pleaded guilty to selling secrets to Russia. Canadian Forces Sub-Lt. Jeffrey Paul Delisle, the CBC reports, simply walked into the Russian Embassy in Ottawa and offered to work for them.

JP Morgan Chase CEO Jamie Dimon, wearing a dark suit possibly made of sackcloth, didn't hold back when discussing the derivative trades that led to massive losses for his company.

"We made a stupid error," he said before a lunchtime audience at the Council on Foreign Relations in Washington on Wednesday. "We screwed up."

Then he got more specific: "I should have caught it ... I didn't."

The company estimates it lost $5.8 billion, thanks to a London-based trader, nicknamed the "London whale," who took large, risky positions in credit derivatives.

The Romney campaign is putting more meat on the bones of its defense policy, and the result is a muscular, almost hawkish posture.

Dov Zakheim, Mitt Romney's special adviser for foreign policy and national security, went toe-to-toe with Richard Verma, who plays a similar role for the Obama campaign, at a forum Wednesday.

The two tussled for over an hour in a foreign policy debate of sorts at a Washington, D.C., hotel.

In 2006, Roger Arias went into his garage searching for a long-lost treasure. He remembered a story about his grandmother and a Spanish translation of "The Star-Spangled Banner."

"I dug through my boxes and sure enough, there was a folder," he says. "It said 'The National Anthem,' and she had version 1 through 10. She kept every one of them."

When Pope John XXIII announced the creation of the Second Vatican Council (also known as Vatican II) in January 1959, it shocked the world. There hadn't been an ecumenical council — an assembly of Roman Catholic religious leaders meant to settle doctrinal issues — in nearly 100 years.

"Many people maintained that with the definition of papal infallibility in 1870, councils were no longer needed. So it was a big surprise," Georgetown University professor Rev. John W. O'Malley says.

It's been a tumultuous time for American orchestras. Labor disputes have shut down the Minnesota Orchestra and Indianapolis Symphony, and strikes and lockouts have affected orchestras in Chicago, Atlanta and Louisville in the past year.

Though it's been around for three decades, 3-D printing has finally started to take off for manufacturing and even for regular consumers. It's being used for making airplane parts on demand and letting kids make their own toys. One designer is pushing the limits of 3-D printing by using it to make an acoustic guitar.

Measurement has long been a cornerstone of quality improvement, whether it's on the factory floor or the hospital ward.

And making the quality scores of doctors and hospitals publicly available is central to the idea that health care can become a service that patients shop for intelligently. The results can also ratchet up professional peer pressure for improvement.

But does public reporting lead doctors and hospitals to game the system by withholding care from the sickest patients?
