First lady Michelle Obama wears many hats in the White House. In addition to being President Obama's closest confidante, she's also a mother whose two daughters are growing up in one of the most public homes in America.

And as first lady, Mrs. Obama has taken on her own signature public issues, as well.

Her Let's Move campaign has brought attention to the growing epidemic of childhood obesity. She has encouraged children to eat right and get plenty of exercise.

Chin up. Literally.

A big group of plastic surgeons say that chin enhancement was the fastest growing surgical procedure they performed for cosmetic purposes in the U.S. last year — up 71 percent to 20,680 operations.

Now, it's still a small number, overall, compared with breast augmentation, the No. 1 procedure at 307,180. But those surgeries rose only 4 percent in 2011 compared with 2010.

Chin work was most popular out west, which is true for most cosmetic procedures. The Northeast came in second.

The Secret Service, which has been offering protection to presidents since 1902, has long enjoyed one of the most sterling reputations of any government agency.

That reputation has been tarnished by allegations that agents hired prostitutes in Colombia in advance of President Obama's trip there.

Saxophonist Andrew Love of the Memphis Horns has died. Love, who had Alzheimer's disease, died on April 12 at his home in Memphis. He was 70 years old.

For its "distinguished ... reporting on significant issues of local concern," reporter Sara Ganim and The Patriot News of Harrisburg, Pa., have won a 2012 Pulitzer Prize for uncovering the so-called Penn State scandal.

Other prize winners, which were just announced, include:

The United Nations Security Council issued a strong condemnation after North Korea's failed satellite launch attempt. Such condemnations were also issued in 2006 and 2009. In a piece in Foreign Affairs, Dartmouth College government professor Jennifer Lind argues that North Korea gets too many second chances.

Want extra salt with that fast-food meal? Then buy it in the United States, where chicken dishes, pizzas, and even salads are loaded with far more salt than in Europe and Australia, according to new research.

The McDonald's Chicken McNuggets in the United States have more than twice as much salt as their sister nuggets in the United Kingdom. That's 1.6 grams of salt for every 100 grams of American nugget, compared with 0.6 grams in the U.K.

The World Bank's executive directors have chosen Dr. Jim Yong Kim to be the development agency's next president.

This is TALK OF THE NATION. I'm Neal Conan in Washington. We don't know much about Saturday's talks in Istanbul between Iran and the group of six major powers, but all sides used positive terms like constructive and agreed to a second round in Baghdad.

While diplomacy continues, the United States warns that the window for talks is closing. There's open talk of preemptive air strikes in Israel, and ever-tightening sanctions continue to squeeze Iran's economy.

The documentary Bully caught national attention when it received an R rating for harsh language from the Motion Picture Association of America. Harvey Weinstein, co-chairman of The Weinstein Company — which distributed the film — discusses the decision to re-edit the film for release with a PG-13 rating.

Foreclosure filings in March fell to their lowest level in four years. Some analysts see the market healing and turning around, yet others argue the next wave of foreclosures are just around the corner. NPR's Chris Arnold discusses how housing markets are faring across the nation.

The fact that there has been a salmonella outbreak among people who eat sushi isn't super surprising; raw seafood does pose more health risks than cooked fish.

But the fact that the fish implicated in the outbreak is something called "tuna scrape" sure got our attention here at The Salt.

According to the Food and Drug Administration's recall notice, tuna scrape is "tuna backmeat, which is specifically scraped off from the bones, and looks like a ground product." In other words, tuna hamburger.

The Justice Department and 41 Native American tribes recently announced a roughly $1 billion settlement. The agreement settles long-standing disputes over whether the federal government mismanaged tribal money and resources.
