(SOUNDBITE OF SOUND EFFECTS)
WERTHEIMER: Any fan of "Dr. Who" recognizes that sound. It's a whirling blue police call box, a tardis, transporting the main character on the long running BBC program. The plot line has the Doctor regenerating ever so often. Which means a new actor comes in to play the title role, and now the 50-year-old science fiction show has just named its 12th Doctor.
Over the weekend the tiny town of Fancy Farm, Kentucky was the scene of a political brawl worthy of the Hatfields and McCoys. No one was run out of town, but Mitch O'Connell, the Senate Republican leader, who is asking Kentuckians for a sixth term, did get pretty roughed up - verbally. You'd hardly guess it all began as a church picnic.

Ecologist William Burnidge checks a map of Fox Ranch that details the different areas rancher Nathan Andrews can graze his cattle.
The world's soil is in trouble. Ecologists say without dramatic changes to how we manage land, vast swathes of grassland are at risk of turning into hard-packed desert. To make sure that doesn't happen, researchers are testing out innovative ways to keep moisture in the soil.
In eastern Colorado, one way could be in the plodding hooves of cattle.
Conventional wisdom tells you that if ranchland ground has less grass, the problem is too many cows. But that's not always the case. It depends on how you manage them, if you make sure they keep moving.
When Sally O'Neill's doctor told her she had an early form of cancer in one of her breasts, she didn't agonize about what she wanted to.
The 42-year-old mother of two young girls wanted a double mastectomy.
"I decided at that moment that I wanted them both taken off," says O'Neill, who lives in a suburb of Boston. "There wasn't a real lot of thought process to it. I always thought, 'If this happens to me, this is what I'm going to do.' Because I'm not taking any chances. I want the best possible outcome. I don't want to do a wait-and-see."
