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.
It's not so far-fetched. Some schools around the country are already using computer programs to help teach students to write.
There are two big arguments for automated essay scoring: lower expenses and better test grading. Using computers instead of humans would certainly be cheaper, but not everyone agrees on argument No. 2.
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. I hope I'll make it easier to understand how science works, and just how cool the process of discovery and innovation really is.
A lot of science involves failure, but there are also the brilliant successes, successes that can lead to new inventions, new tools, new drugs — things that can change the world
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:
A: How he did it.
B: Where Democrats failed.
My colleague Ron Elving, NPR's senior Washington editor, took a good shot at answering Question A Wednesday morning.
New research out today indicates that a popular medical test may increase the risk for some forms of cancer. A large international study found that CAT scans, which are also known as CT scans, can increase the risk for leukemia and brain cancer in children.
NPR's Rob Stein joins us now to talk about the new findings. And, Rob, I understand the concerns about these scans have been building for a long time. So what's the specific source of worry here?
