President Obama is back in Washington Saturday after visiting five different states, all of which are likely to be hotly contested in November. He expanded on some of the ideas he outlined in Tuesday's State of the Union address and offered a preview of the argument he'll be making in the general election. NPR's Scott Horsley reports.

An illegal Jewish outpost in the occupied West Bank is at the center of a swirling battle over settlements. The collection of trailers and makeshift buildings is called Migron, and the Israeli Supreme Court has said that it must be dismantled by the end of March. NPR's Lourdes Garcia-Navarro reports.

Martin Mull and Fred Willard are comic partners in many minds. They helped create Fernwood Tonight in the late 1970s, and while they went on to solo careers in films and stage, they were reunited to play one of TV's first gay couples on Roseanne. Host Scott Simon sat down with the duo for the public television show Backstage With.

Former House Speaker Newt Gingrich made appearances before two communities in Florida Friday whose votes he hopes to win in next Tuesday's GOP primary. He spoke to Latino home builders and business people in the morning, and had a rally with a group of Republican Jewish voters in the afternoon. NPR's Brian Naylor reports.

The future of the state of the U.S. housing market was a primary focus for the White House this week. On Tuesday's State of the Union address, President Obama unveiled a new plan to try to correct the housing downturn. It would allow qualifying homeowners the chance to refinance their mortgages at historically low rates.

This week, Egyptians marked the first anniversary of the uprising that led to the ouster of President Hosni Mubarak. Deepening political divisions between pro-Islamist and secular protesters marred the event, erupting into violent scuffles. NPR's Soraya Sarhaddi Nelson reports.

Last week we spoke with Christian Bale who stars in the new film, The Flowers of War. Also, Gwen Thompkin's personal appreciation of Etta James moved many listeners to tears, laughter and reflection. Host Scott Simon reads listener reaction to last week's program.

The women's finals in the Australian Open are already over. In baseball, power-hitter Prince Fielder has returned to his childhood team, the Detroit Tigers, for which his father played. Host Scott Simon talks sports with Howard Bryant of ESPN the Magazine and ESPN.com.

A niche industry of tour companies is taking people into wolves' habitat at Yellowstone National Park. Montana Public Radio's Dan Boyce went on an expedition with a man who recognizes the problems wolves bring to the landscape even as he makes his living off of them.

What do you do when the conversation lags? Our friend Richard Glover of the ABC in Sydney, Australia might know. This week he and sports author and journalist Peter FitzSimons set a new Guinness World Record for Longest Radio or TV interview: 24 hours, with only an occasional loo break.

I will watch the Super Bowl next weekend, along with several billion other people. I expect to cheer, shout and have some guacamole.

But as a fan, I'm finding it a little harder to cheer, especially for my favorite football and hockey players, without thinking: They're hurting themselves.

Not just breaks and sprains but dangerous, disabling brain damage.

Think you know how to avoid overeating? Think again.

Research suggests that choices, like how much to eat during a meal, are often made subconsciously. Trouble is, our brains are hard-wired to mislead us in lots of little ways, which can have a big impact on our diets.

Take the Delboeuf effect, an optical illusion first documented in 1865. It starts with two dots of equal size. But surround one dot with a large circle and the other dot with a small one, and suddenly the second dot looks bigger.

The argument over whether voters should have to present photo identification at the polls usually splits along party lines. Republicans who favor the requirement say it prevents ballot fraud. Democrats and election rights groups who oppose it say it is meant to suppress turnout.

And people of all political stripes wonder what all the fuss is about.

NBC's new drama, Smash, plumbs the drama behind the curtain. The series is the story of a Broadway musical — from the first idea, to auditions, rehearsals and the big premiere.

Theresa Rebeck is the show's creator and executive producer. She's also a screenwriter, playwright and a Broadway veteran — with a hit play "Seminar," that's now on Broadway.

Rebeck tells Weekend Edition host Scott Simon that Smash is a "workplace drama — it's just that the workplace is a musical."

After his second-place finish in the South Carolina primary, Mitt Romney arrived in Florida armed with money and organization. He's used both to stop Newt Gingrich's momentum. With three days until the primary, polls give Romney a solid lead over Gingrich in Florida.

Florida is a big state, but Romney and Gingrich's paths have crossed often this week. There were the two debates, and in Miami, like Gingrich, Romney spoke to the Hispanic Leadership Network Friday.

British writer Penelope Lively was in her late 30s before she began her career writing children's books. Now, four decades and 20 works of fiction later, she has just released the novel How It All Began, in which she explores the capricious role that chance plays in our lives.

Lively's lifetime habit of storytelling began when she was growing up in Egypt during World War II. She spent a lot of time alone and amused herself by making up stories, which often involved embellishing the classics with her own personal touch.

In Mexico, where criminals are armed to the teeth with high-powered weapons smuggled from the United States, it may come as a surprise that the country has some of the most restrictive gun laws in the world.

Law-abiding Mexicans who want a gun to defend themselves have no good options. Either they fight government red tape to get a legal permit, or they buy one on the black market.

After an outbreak of violence, one embattled community in northern Mexico called Colonia LeBaron has begun to ask if it's time for the country to address its gun laws.

Politics may be show business for ugly people, but you don't have to be ugly about it yourself.

It's become a cliche to describe the endless series of Republican presidential debates as a reality show. But lately a lot of politicians have been acting as though they were looking to secure a spot on the "now trending" lists of Internet search engines.

Secretly donating sperm to lesbians in New Zealand? Seriously?
