DAVID GREENE, HOST:
And I'm David Greene. We have learned this morning that North Korea has agreed to a moratorium on nuclear tests and uranium enrichment activities. This is according to State Department officials just back from a trip to China, where they met with North Korean negotiators. NPR's Michele Kelemen has more on what could be a step towards reviving nuclear disarmament talks.
Media baron Rupert Murdoch's son James, 39, is leaving his job as executive chairman of News Corp.'s newspaper arm, the company said Wednesday. He'll focus instead on the international TV business at the company, which has been embroiled in a scandal over phone and e-mail hacking in Britain.
At this year's fishing contest on Lake Winnebago in Wisconsin, they weren't just fishing for sturgeon. People arriving to fish parked their cars too closely, and the ice gave way. No one was hurt but three dozen vehicles were pulled out of the lake.
Pakistani journalist Pir Zubair Shah has been following drone strikes in the border region between Pakistan and Afghanistan for more than half a decade. He talks to Morning Edition's Steve Inskeep about his recent article in Foreign Policy magazine titled "My Drone War."
NPR's business news starts with an invitation from Apple.
Journalists were invited yesterday by Apple for a product event next month. And that was enough to send the company shares to another all-time high. There's wide speculation the event will introduce the next generation of its iPad tablet. The iPad 3 is expected to have a faster processor and a high definition display.

And that brings us to our last word in business on this Leap Day: a rare proposal. Traditionally in many European countries Leap Day was considered the only day when a woman could propose to a man. And one restaurant in Swindon, England seems to be capitalizing on that.
GOP presidential hopeful Mitt Romney turned back challenges from former Pennsylvania Senator Rick Santorum in Arizona., where Romney won easily, and in Michigan, where he eeked out a close win in the state where he was born. Before Tuesday night, Romney's last primary win was in Florida a month ago.
And while Mitt Romney was eking out that win in Michigan, he pretty much walked away with yesterday's Arizona primary. Romney was expected to win in Arizona, but he walloped his closest challenger - that would be Rick Santorum - by 20 percentage points. Helped, in part, by the support of the last Republican presidential nominee, Arizona Senator John McCain.
And while all the attention was on Michigan throughout the night, NPR's Ted Robbins reports that in the all-important delegate count, the Arizona win counts for nearly as much.
