Wind power is all the rage in Oklahoma and could be a boon in a state that has been hit hard by unemployment. The problem is finding qualified people to work in the industry.

Dunkin Donuts is aiming to nearly double its outlets in China. To help meet its goal, the donut chain has come up with pork donuts. The company even recruited NBA star LeBron James to pitch the new treats to Chinese consumers.

Mitt Romney won six of the 10 Super Tuesday contests. Rick Santorum won three while Newt Gingrich won one. Ron Paul was the only candidate who did not win at least one contest.

President Obama held a wide-ranging news conference Tuesday. He bluntly challenged Republican critics of his Iran policy — saying the stakes are too high to let politics intrude. The news conference was designed to steal some of the spotlight from GOP presidential hopefuls on Super Tuesday.

GOP presidential candidate Rick Santorum won three Super Tuesday contests: Oklahoma, North Dakota and Tennessee. He just missed in Ohio. Mitt Romney went on to win there.

Mitt Romney won the GOP presidential primary in Ohio Tuesday night. Unlike most of the other states voting on Super Tuesday, Ohio will be a pivotal swing state in the general election.

RENEE MONTAGNE, HOST:

Let's devote the next few minutes to the subject that President Obama began his press conference on, the U.S. housing market. The president pointed out that in many ways the U.S. economy is looking up. But...

PRESIDENT BARACK OBAMA: There are still millions of Americans who can't find a job. There are millions more who are having a tough time making the rent or the mortgage, paying for gas or groceries. So our job in Washington isn't to sit back and do nothing. And it's certainly not to stand in the way of the recovery.

When the state of California added the compound 4-methylimidazole, also known as 4-MI or 4-MEI, to its list of known carcinogens in 2011, it created a problem for the soda industry.

The caramel color they used to give colas that distinctive, brown hue contained levels of 4-MI that would have warranted a cancer warning label on every can sold in the state.

Tina Brown, editor of The Daily Beast and Newsweek, tells us what she's been reading in a feature that Morning Edition likes to call "Word of Mouth." This month, Brown selects two pieces of writing profiling individuals at the center of political change in their respective countries.

A Penetrating New Profile Of Russia's Putin

Nearly four years ago, the bank collapsed in the biggest bankruptcy in U.S. history — a record $639 billion. That set off a chain reaction and sent the economy spiraling. Lehman Bros. says now, it will continue to liquidate its holdings, and will start paying back creditors next month.

Rebekah Speight spotted the familiar profile on a McNugget left on her child's plate. After stashing it in the freezer for three years, she auctioned it off on eBay. Her church's summer camp will benefit from the winning $8,000 bid.

Navy Secretary Ray Mabus says he wants personnel to adapt to the 21 century. He announced the Navy will give sailors breathalyzer tests and drug tests before they report to duty on a ship. The Marines will adapt a similar program next month.

People have been avoiding checked-baggage fees by carrying on bags — that includes bags too big for the overhead bins. Now United and Delta Airlines are enlarging the bins. There is some fear, however, this will prompt people to bring bags that are even larger.

Russia's opposition is turning to the streets to protest Sunday's presidential election which returned Vladimir Putin to power. The protesters may have agreed on a set of very catchy slogans, but they're not a cohesive political movement.

NPR's Dan Charles has been looking into the problem of weeds that America's most widely used weed-killer won't kill anymore. It's a sneak preview of a story that will air later this week.

RENEE MONTAGNE, HOST:

OK. And we all noticed rising costs at the gas pump. But those costs will also mean rising prices for airline tickets.

As NPR's Annie Baxter reports, that's already happening.

ANNIE BAXTER, BYLINE: If you've been looking for a great deal on airline tickets recently, you've probably been disappointed.

BOB MANN: Carriers have raised prices successfully twice, so far this year and that's out of four attempts. And I would expect another attempt literally within in a week.

First responders never know what they'll find when they get called to an accident site. Sometimes crews have to rescue dairy cows from collapsed barns, evacuate horses during wildfires or move pigs off the highway after an accident. These first responders often don't have the proper training to handle large animals.

Republican presidential candidates have a chance to win hundreds of convention delegates after voters cast their ballots in Super Tuesday contests. The delegate count wouldn't be enough for any candidate to clinch the nomination, but it would help. Mitt Romney is hoping to return to front-runner status but Rick Santorum, Newt Gingrich and Ron Paul are trying to prevent that.

Morning Edition has four reports on Monday's campaigning leading up to Super Tuesday's 10 primaries and caucuses.

NPR's Don Gonyea was traveling with former Senator Rick Santorum in Ohio.
