With the 2012 presidential election on the horizon, NPR's Debbie Elliott heads to Camden, S.C., to hear from the close-knit Gaither-James family. Like other African-Americans — considered the political base for President Obama — they're concerned about the economy and today's political climate.

Have you ever been at a bar where it was just too loud to hit on anybody? Birds feel your pain.

A big part of being a bird is singing, often to attract other birds. Sometimes it's hard to do that amid all the noise in a city. For birds, it's like living in a bar, scientist Peter Marra says.

"Those sounds compete with low-frequency sounds," Marra says, and that makes it hard for birds that sing at a lower pitch to hook up.

But there's no stopping love, and Marra has found that those birds are changing their tune.

This year has something unpleasant in common with the years 1979 and 1986. In 1979, a nuclear reactor at Three Mile Island in Pennsylvania melted down. In 1986, the Soviet reactor at Chernobyl blew up and burned.

This year's meltdown occurred in Fukushima in Japan, and nuclear power isn't likely to be the same as a result.

Nuclear power had enjoyed 25 years of relative quiet, but the Fukushima accident reminded people that despite improvements in safety, nuclear plants could still go horribly wrong.

For some, though, nothing has changed much.
