Update at 10:12 a.m. ET. It's Official:

"It's time for a development professional to lead the world's largest development agency," President Obama just said as he announced he is nominating Dartmouth College President Jim Yong Kim to head the World Bank.

Our original post:

"President Barack Obama will nominate Dartmouth College President Jim Yong Kim to head the World Bank," The Associated Press reports, citing "senior administration officials" as its sources.

On Saturday Louisiana holds its Republican presidential primary, and Friday all four remaining candidates will be campaigning in the state. Rick Santorum and Newt Gingrich, both of whom have won other Southern primaries, have been in and out of Louisiana all week, hoping to keep their slim chances at the GOP nomination alive with another win there.

Neither a balky sound system nor a gale that delayed Santorum's motorcade dampened the enthusiasm of members of the Mandeville Tea Party earlier this week.

Along with the word that U.S. Army Staff Sgt. Robert Bales will be formally charged with murder today for the deaths of unarmed Afghan men, women and children on March 11, was the news that the death toll had grown to 17. Until Thursday afternoon, U.S. military officials had consistently said that 16 people were killed.

As The Associated Press has reported, officials made the change without offering a public explanation for it.

Tough defense by Louisville led to the defeat Thursday night of Michigan State in the NCAA men's basketball tournament, NPR's Mike Pesca said earlier on Morning Edition.

The Spartans, who lost to Louisville 57-44, are the first of the four No. 1 regional seeds to be sent home.

Syracuse, another No. 1 seed, managed to hang on with a 64-63 win over Wisconsin. In Thursday's other two games, Florida beat Marquette 68-58 and Ohio State thumped Cincinnati, 81-66.

Trayvon Martin was "a typical teenager who would end up in a casket, buried in white suit with a powder blue vest," the Miami Herald writes.

Thousands of people are expect to descend on the Mall in Washington, D.C., on Saturday to celebrate not believing in God. It's being called a sort of "Woodstock for Atheists," a chance for atheists to show their power in numbers and change their image.

The "Reason Rally" could attract up to 30,000 people; organizer David Silverman says it marks a coming-of-age for nonbelievers.

"We'll look back at the Reason Rally as one of the game-changing events when people started to look at atheism and look at atheists in a different light," Silverman says.

This is the first of two stories we're doing on Harrisburg. Read the second story here.

Eric Papenfuse owns a bookstore in Harrisburg, Pa. He used to be on the city agency in charge of basic municipal services — sewer, water, trash.

The Supreme Court will hear oral arguments next week on, among other things, whether the 2010 health law can require most Americans to have health insurance starting in 2014.

The so-called individual mandate is the centerpiece of the law, and the conventional wisdom says the rest of the law will crumble if it is found to be unconstitutional.

But many policy wonks say that's not necessarily the case.

And now, let's get down to the campaign trail. In the race for the Republican nomination, the scene has shifted to Louisiana which is holding its primary tomorrow. Today, all four of the remaining GOP candidates are campaigning in the state.

Most of the media focus is on Rick Santorum and Newt Gingrich. Both men have won other southern primaries, and both have been in and out of Louisiana all week long, hoping a victory there will keep their slim chances of winning the GOP nomination alive. Here's NPR's Brian Naylor.

Let's go now to Florida, where late yesterday Governor Rick Scott announced that a new state attorney has been assigned to investigate the shooting death of Trayvon Martin. The announcement came as thousands rallied in Sanford demanding justice for Martin. The teen was shot as he walked unarmed in Sanford, a suburb of Orlando. The shooter, George Zimmerman, is a volunteer neighborhood watch captain and he claims self-defense. He's also not been arrested. As NPR's Kathy Lohr reports, the cry is growing louder for an arrest to be made.

DAVID GREENE, HOST:

Now, even if the shooter, George Zimmerman, is arrested for the death of Trayvon Martin, a conviction could be hard to get because of the controversial law that Kathy mentioned in her report. Let's take a closer look at that law. It's called Stand Your Ground and it allows people to use deadly force to defend themselves when confronted with a threat of violence. It's been on the books in Florida for several years. And as NPR's Greg Allen reports from Miami, it was a source of controversy long before the Martin shooting.

North Korea agreed, last month, to freeze uranium enrichment and missile tests in exchange for large amounts of food aid from the United States. American officials thought they had an understanding, but then last week North Korea announced it would be launching a satellite using a long-range missile. As NPR's Mike Shuster reports from Seoul, all this is now threatening to overshadow next week's global nuclear security summit in Seoul, which President Obama is planning to attend.

Mohamed Mehra, the self-confessed gunman who terrorized the French city of Toulouse, was killed yesterday in a shootout with French police. Authorities had hoped to bring him in alive, to find out what drove him to commit the attacks that left seven dead, including three children at a Jewish school. Now, France is left to wonder whether its intelligence services missed signs that could've prevented the tragedy. NPR's Eleanor Beardsley sends this report.

Thousands of Portuguese workers walked off the job yesterday. They were protesting austerity measures tied to the country's $100 billion bailout from the European Union and International Monetary Fund.

Let's go to Lisbon now. Lauren Frayer reports that among protesters a sense of despair and confusion are more prevalent than anger.

Pope Benedict XVI begins a visit Friday that takes him to Mexico, a country with around 100 million Catholics, and to Cuba, a place where church leaders have played an increasingly active role in seeking change.

There are sensitive issues in both countries that the pope is likely to address in some form. In Mexico, it's the brutal drug war that has claimed roughly 50,000 lives over the past five years.

On Friday's Morning Edition, Elizabeth Blair investigates one of television's pressing questions: Why has Mad Men been off the air so long? It's returning this Sunday night with a two-hour season premiere, but it's still puzzled some viewers that it has been off for such a long time.
