On July 1, the European Union says it will stop buying oil from Iran. Europe is one of the most important markets for Iran's oil, and in anticipation of the boycott, Iranian oil exports worldwide are already down by more than 25 percent.

As a result, it appears as if Iran will only face even greater difficulties when it comes to exporting oil, the lifeblood of its economy.
Imagine a school where every child gets instant, personalized writing help for a fraction of the cost of hiring a human teacher — and where a computer, not a person, grades a student's essays.

This summer, my big idea is to explore the big ideas of science. Instead of just reporting science as results — the stuff that's published in scientific journals and covered as news — I want to take you inside the world of science.

NPR Morning Edition host Steve Inskeep is taking a Revolutionary Road Trip across North Africa to see how the countries that staged revolutions last year are remaking themselves as they write new social rules, rebuild their economies and establish new political systems. Steve and his team are traveling some 2,000 miles from Tunisia's ancient city of Carthage, across the deserts of Libya and on to Egypt's megacity of Cairo.

Children who get CT scans are at slightly increased risk for brain cancer and leukemia, according to a large international study released Tuesday.
CT scans create detailed images of the inside of the body. So they're great for diagnosing all sorts of medical problems — so great that their use has soared in recent years. More than 80 million are being done every year in the United States.
The morning after Republican Gov. Scott Walker of Wisconsin handily rebuffed Democratic efforts to oust him, politicos in the state and beyond pored over exit poll data and turnout numbers to tease out:
