Rick Santorum headed in a different direction after his wins on Tuesday.
Here's NPR's Wade Goodwyn in Dallas.
WADE GOODWYN, BYLINE: North Texas was a good choice for former Pennsylvania Senator Rick Santorum to keep his campaign's momentum going. He met with evangelical pastors in the morning, Tea Partiers in the afternoon and a Republican women's group at night.
(SOUNDBITE OF MEETING)
UNIDENTIFIED WOMAN: It is our pleasure to introduce to you Rick Santorum. Give him a Texas welcome.
And that settlement is, of course, a priority for President Obama. But so is the debt crisis in Europe. Today, he hosts Italy's new prime minister, the technocrat who succeeded the controversial-but-flamboyant Silvio Berlusconi last fall. Mario Monti has not yet turned around Italy's economy, but as NPR's Sylvia Poggioli reports, he's changed the government's image abroad.
We're going to look now at American military strategy for the war in Afghanistan. There's been some confusion lately about whether American forces would end their combat mission sooner than planned and also about how long the U.S. will remain in Afghanistan. So to try to make sense of it all, we're joined by NPR Pentagon correspondent Tom Bowman.
Russia's support for Syrian President Bashar Assad has put it at odds with other countries in the Arab world.
Russia drew a lot of flack from Arab countries and the West when it vetoed a U.N. Security Council resolution aimed at pressuring Assad to stop his crackdown on protesters. That has some analysts in Russia doubting whether the Kremlin really has a cogent strategy for the Middle East.
The dilemma for Russia policy in the Arab world can be illustrated by two very different events that took place this week.
Tai chi, the Chinese martial art involving slow and rhythmic movement, has been shown to benefit older people by maintaining balance and strength. Now, researchers have found that tai chi also helps patients who suffer from Parkinson's disease.
Leona Maricle was diagnosed with Parkinson's two years ago. At the time, she was teaching math, and she says she had experienced the telltale tremors of Parkinson's for a number of years. She learned how to cope.
Turn on the news on any given day, and you're likely to hear about the Dow Jones industrial average. It is the most frequently checked, and cited, proxy of U.S. economic health. But a lot of people — maybe most — don't even know what it is. It's just the stock prices of 30 big companies, summed up and roughly averaged. That's it.
And what does the daily movement of this number have to do with the lives of most Americans? Not much.
American lawmakers are furious about a mounting diplomatic crisis in Egypt, where dozens of nongovernmental workers, including 19 Americans, could face trial.
The United States says Egypt needs to let pro-democracy groups continue their work to help the country's transition, but Egypt accuses them of operating illegally.
The work of democracy promotion groups has raised suspicions in many countries, but Lorne Craner, who runs the International Republican Institute, says he has never seen anything like what's going on now in Egypt.
Labor unions plan to rally in front of the Arizona State Capitol on Thursday afternoon to protest four bills quickly moving through the state Legislature that could make last year's Wisconsin labor laws look modest by comparison.
Three of the four bills restrict the way unions collect dues and the way workers get paid for union activities. The fourth bans collective bargaining between governments and government workers: state and local. Unlike Wisconsin, it affects all government employees, including police and firefighters.
Stroll along a street in downtown Shanghai for very long, and you're likely to run into someone wearing Converse Chuck Taylor All Stars. One recent afternoon, Xu Jing was heading back from lunch to her job at an ad company in a pair of raspberry-colored Chuck Taylors.
"They have a young image, upbeat and outdoorsy, sporty," said Xu, 27, explaining the appeal. "Young people with an artistic sense prefer Converse."
Xu was accompanied by Chen Xiaolei, a co-worker who owns three pairs of Chuck Taylor high-tops.
You didn't have to look hard to see this one coming.
Catholics and GOP candidates have attacked the Obama administration's plans to require most employers — including religious hospitals and schools — to provide coverage of prescription contraceptives. Now the debate is moving to Capitol Hill.
Fresh off his hat trick in Minnesota, Colorado and Missouri, former Pennsylvania Sen. Rick Santorum campaigned in Texas on Wednesday, speaking to a group of pastors at Bella Donna Chapel in the town of McKinney.
Forty miles north of Dallas, where black prairie dirt meets the fresh poured concrete of suburbia, this is Rick Santorum country.
Here are two things you don't often hear mentioned in the same sentence: social media and nuclear weapons.
Rose Gottemoeller, acting undersecretary of state for arms control, quickly links those two unlikely partners in conversation. She's behind a campaign to discover how new communications tools can help rid the world of some of the dangers of nuclear weapons.
Crowdsourcing Nuclear Problems
Gottemoeller is an avid user of Twitter, and it made her wonder how Twitter and other methods of crowdsourcing a problem can help her in her work.
Down a quiet Beijing alleyway on a recent day, as the winter wind whistles, two men stand guard over a pile of bricks hidden behind a corrugated iron fence.
The pile of rubble was once the home of the man known as the father of modern Chinese architecture, Liang Sicheng. The Orwellian reason for its demolition? "For maintenance," according to a Xinhua news agency report, citing the developer, Fuheng Real Estate company.
Morning Edition has been asking people what music makes them move, in order to create The Ultimate NPR Workout Mix. The mix already includes a good selection of Kanye West, 2Pac and Madonna — which is just fine for some people.
The Earth's continents are in constant motion. On at least three occasions, they have all collided to form one giant continent. If history is a guide, the current continents will coalesce once again to form another supercontinent. And a study in Nature now shows how that could come about.
You can think of continents as giant puzzle pieces shuffling around the Earth. When they drift apart, mighty oceans form. When they come together, oceans disappear. And it's all because continents sit on moving plates of the Earth's crust.
Republican presidential candidate Mitt Romney's losses on Tuesday, while not very meaningful in the race to accumulate delegates, have raised questions once again about his ability to inspire passion from his party's base and about his viability in the general election.
Rival Rick Santorum's victories in Colorado, Missouri and Minnesota dealt a setback, if not exactly a body blow, to Romney — whom Santorum routinely dismisses as a candidate with a big machine but no core.
Ask Detroit teachers about their biggest challenge and many will say, "You can't teach kids who don't come to class." Last year, the average Detroit public high school student missed at least 28 days of school.
Now, as part of its effort to get parents more involved, the district has launched a major initiative to improve attendance. The effort includes parent workshops and attendance agents charged with pushing parents to send their kids to school every day.
Dolphins have been stranding themselves along the shores of Cape Cod, Mass., since the Pilgrims' times, and this winter is no different. What is different is how long the latest round of strandings has lasted — almost a month. So far, rescuers have counted 147 strandings and 38 successful rescues and releases.
Anti-government protests in Russia are taking many different forms, from mass rallies and marches to defiant street art and music.
Just recently, members of a feminist punk group were arrested in Moscow's Red Square after they performed a song ridiculing Prime Minister Vladimir Putin. The group, which calls itself Pussy Riot, says it's planning more stunts before March's presidential elections.
Most moms probably don't want their babies around pot growers, but San Francisco-based writer-photographer Lisa Hamilton is totally cool with it.
In fact, her baby, Ada, is a little over a year old and has probably already seen more of California than most Californians. And that, to Hamilton, is a problem.
For her, the basic issue is exemplified by something like this: We can see what a stranger in Japan is having for lunch on Instagram. But we can't so easily see where that lunch came from, or who harvested the ingredients.
