In 2013, after George Zimmerman was acquitted for killing 17-year-old Trayvon Martin, a young woman in California named Alicia Garza wrote an emotional Facebook post that ended with the words "Our Lives Matter, Black Lives Matter." Her friend, Patrisse Cullors, turned that into a hashtag.

The roar of a car bomb has been the prelude to Karim Wasfi's performances of late.

It's the end of a tough week in Baltimore. Tensions continue in the Freddie Gray case. And now the murder rate has spiked to a 40-year high. One man who understands well what the city is going through is Kurt Schmoke. He's a native son and was elected as Baltimore's first black mayor in 1987. He served three terms, grappling with high unemployment, poor schools and violent crime.

Now the president of the University of Baltimore, Schmoke shares his memories of the city and his thoughts about moving it forward with Morning Edition.

Gen. Martin Dempsey has spent more than a decade dealing with Iraq, and as his tenure as chairman of the Joint Chiefs winds down, he sees a conflict that will long outlast his time in uniform.

Dempsey helped train the Iraqi military from 2005 to 2007 in what he describes as a "debacle" in the early stages. He saw the rapid rise of the self-described Islamic State, also known as ISIS or ISIL. And now he oversees the U.S.-led bombing campaign against the extremist group in both Iraq and Syria.

And he has no illusions it will be quick or easy.

Maybe you've noticed a dish that keeps popping up in more restaurants across the U.S.

Peru is one of the countries that lays claim to ceviche, which is made of raw fish and chilies, cured in lime juice.

So how do you know you're tasting a perfect ceviche?

"In the first bite, you want to find a strong citrus flavor balanced with the fish, and a little bit spicy, but a fresh spicy given by a fresh chili," says chef Gaston Acurio.

Actor Wilbur Fitzgerald rated highly (surprise, surprise):

But most of you who responded are not actors. And it turns out, you don't need professional training to impress man or machine.

Around this time 70 years ago, following the liberation of Nazi concentration camps in Europe, the world was coming to grips with the scale of the holocaust, and how to deal with crimes so horrendous, they're almost incomprehensible.

That process is still ongoing.

Right now in Germany, a 93-year-old former Nazi who served at Auschwitz is on trial. Holocaust survivor Eva Kor flew to Germany to testify about her experience in the camp.

The self-declared Islamic State gained a real grip on Iraq and Syria this week, capturing the cities of Ramadi and parts of Mosul in Iraq, and the ancient town Palmyra, Syria.

Most recently, ISIS has claimed credit for a suicide bomb attack inside Saudi Arabia on a Shiite mosque during Friday prayers. That attack killed at least 19 and could represent a significant escalation of the extremist group's operations in the kingdom.

The challenge of strategizing the best route to work against the herd of other drivers can be as routine as the daily commute itself. A number of apps are out there to help shortcut one's route and evade traffic jams. But which ones are the most accurate? And how?

The All Tech Considered team put a few competing traffic apps to the test in Robert Siegel's usual short commute from Arlington, Va., to NPR's D.C. headquarters.

The Test Drive

This ride is about 15 minutes in no traffic. But it's now morning rush hour.

After the Republican presidential candidates finish their first debate this summer, many will head to Atlanta for a summit hosted by Erick Erickson, conservative activist and editor-in-chief of RedState.com.

This year, Erickson's RedState Gathering is scheduled for the same weekend as the Iowa Straw Poll.

Jeb Bush has already indicated he will go to the RedState Gathering rather than Iowa. Scott Walker, Carly Fiorina, Bobby Jindal, Marco Rubio and Rick Perry are also going. Most will try to attend both events, Erickson says.
