In one of this year's most intense international competitions, the United States has come out as best in the world — and this time, we're not talking about soccer.

This week, the top-ranked math students from high schools around the country went head-to-head with competitors from more than 100 countries at the International Mathematical Olympiad in Chiang Mai, Thailand. And, for the first time in more than two decades, they won.

In Northern Ireland, "the Troubles" — the long and bloody conflict between Catholic Irish nationalists and pro-British Protestants — formally came to an end with a peace agreement in 1998.

If you turned on a radio in 1979, there was very good chance you'd hear the music of Rickie Lee Jones. At only 24, she leapt onto the world stage with her big single "Chuck E.'s in Love." Rolling Stone called her "the dutchess of coolsville."

President Obama responded sharply this week when a reporter asked if he was "content" to celebrate the nuclear deal with Iran when at least three and possibly four Americans are being held in Iranian jails.

"Nobody's content," he said, "and our diplomats and our teams are working diligently to try to get them out."

At least one former American hostage thinks the deal is worth signing, despite the remaining hostages.

It's easy to think we're being virtuous when we fill up the blue recycling bin and put it on the curb. But it's clear we have embraced some magical thinking when it comes to what can be recycled.

Morning Edition asked its social media followers to share what puzzles them the most about the recycling process. Then, NPR's Dianna Douglas visited a waste management plant in Elkridge, Md., to get the answers from Michael Taylor, director of recycling operations for the plant.

On Thursday, President Obama became the first sitting president in U.S. history to visit a federal prison, taking a tour of the El Reno Federal Correction Institution in Oklahoma. Earlier in the week, he addressed the NAACP in Philadelphia, calling for reforms in the criminal justice system — with the hopes of helping people who have served time turn their lives around.

Oshea Israel, whom listeners first met through StoryCorps in 2011, has done just that.

Syria's civil war has created the worst refugee crisis in the world, with more than 4 million people fleeing the country. Millions more have been displaced inside Syria, though we rarely hear from them.

Over the past year, NPR's Morning Edition has spoken three times with Saeed al-Batal, a photographer and filmmaker who doesn't use his real name for security reasons.

The "E" in Wisconsin Gov. Scott Walker's newly unveiled presidential logo is a stylized American flag — as it turns out, one that looks remarkably similar to the logo for America's Best Contacts & Eyeglasses.

The company's CEO, Reade Fahs, said he doesn't mind but also that it's unlikely the governor hasn't seen the 18-year-old logo. "It's on hundreds of stores across the country. So assuming he's got good vision, he probably would have spotted it in his campaign travels. And we have lots of stores in Wisconsin too."
