Undecided voters in Ohio got a lot of attention this week from President Obama and GOP rival Mitt Romney. Coal may be the key to many swing voters in the Buckeye State, which remains a top coal producer.

It's an issue weighing on coal miner Rick Carpenter's mind at the Barnesville Pumpkin Festival in southeastern Ohio.

"Save coal — fire Obama. Yeah, I've got one of those signs in my yard," he says.

In 1939, Jessie Lee Bond died. His death certificate says he drowned accidentally, but his family has always maintained that he was lynched after an argument with white shop owners — shot and thrown into the river.

No one has ever been charged with his death.

Decades later, his now-91-year-old brother, Charlie Morris, told StoryCorps in Memphis, Tenn., that he was at school when he was called down to the office and told that his brother had been murdered.

Tunisia was the birthplace of the Arab Spring last year, and many regard it as the most Western-looking nation in the Arab world. Yet it's also waging a roaring debate over how to define freedom of expression in an evolving society.

Tunisian protesters attacked the U.S. Embassy recently in response to the anti-Muslim video Innocence of Muslims. This was just the latest of several episodes in which hard-line Muslims have acted out publicly to what they see as attacks on their religion.

NASA's newest Mars rover, Curiosity, has snapped photos of rocky outcroppings that jut out from the alien soil, and scientists say they look like the remnants of an ancient stream bed where water once flowed on the surface of the red planet.

The exposed rocks look like broken slabs of concrete sidewalk, about four inches thick, and are made of rounded bits of gravel in a sandy matrix. The rock has eroded a little bit, and some of the smooth pebbles — about the size of M&M candies — have fallen down into a little pile.
