All Things Considered

Weekdays, 4-6:30pm and Weekends, 5-6pm

Since its debut in 1971, this afternoon radio newsmagazine has delivered in-depth reporting and transformed the way listeners understand current events and view the world. Every weekday, hosts Melissa Block, Michele Norris, and Robert Siegel present breaking news mixed with compelling analysis, insightful commentaries, interviews, and special -- sometimes quirky -- features. Guy Raz hosts a one-hour edition of the program on Saturday and Sunday.

At the State Department on Wednesday, officials from 68 countries and organizations gathered for a two-day summit to coordinate plans to fight ISIS. This was the first full meeting of the Global Coalition on the Defeat of ISIS since 2014, and a chance for the Trump administration to flesh out what it wants to do differently.

So far, it is mainly stepping up a fight that the Obama administration put in motion.

Angela Chen makes money hawking her ties to important people, running a consulting firm that helps companies connect with Asia's power players.

The February deal, which was first reported by Mother Jones, underscores one of the problems posed by Trump's ongoing business interests.

On a cold and windy day off the coast of Alabama, a team of researchers from Worcester Polytechnic Institute in Massachusetts gathers, conducting the first test outside a laboratory for a potential new solution to a challenging problem: cleaning oil spills from water.

The invention, the Flame Refluxer, is "very simple," says Ali Rangwala, a professor of fire protection engineering: Imagine a giant Brillo pad of copper wool sandwiched between layers of copper screen, with springy copper coils attached to the top.

The German city of Trier has never been particularly fond of its most famous son, Karl Marx, who helped turn communism into an ideology that changed the course of history.

Conservative and Catholic, the picturesque city on the French border took an ambivalent view of the radical revolutionary, born into a Jewish family in 1818.

There's a wall-long mural in the manufacturing area of SilencerCo, in West Valley City, Utah, that shows a crowd of people with muzzled mouths. One's holding a sign that says, "Fight the Noise." Another says: "Guns don't have to be loud."

As a leading manufacturer and seller of gun silencers — or suppressors, as they're more accurately called — SilencerCo wants to quiet guns. Congress may soon help in the effort.

The biopic Selena tells the story of Mexican-American pop star Selena Quintanilla Perez, a Tejano music singer who made a rare crossover to mainstream American audiences. The movie debuted 20 years ago Tuesday, two years after the singer was killed by the former president of her fan club.

For more now, we turn to NPR legal affairs correspondent Nina Totenberg. Hey there, Nina.
