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.
Reddit, billed by its founders as "the front page of the Internet," has long been known as a place of unbridled free speech on the Web where users, known as Redditors, post text, pictures and videos.
But that unbridled free speech sometimes spills over into harassment, sexism and racism. Over the past couple of years, Reddit has been at the center of several controversies concerning harassment, including the release of hundreds of private celebrity photos. It's also become infamous for its unbridled vitriol.
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.
