It's Christmas Eve, and many Latinos will celebrate the holiday tonight by unwrapping a delicious little present: tamales.

At its essence, a tamale consists of masa (a type of starchy corn dough) that's been wrapped in leaves, then steamed or boiled. Some come bundled in corn husks, others in plantain, banana or mashan leaves. Some are sweetened with molasses, others spiced with mole. Some are plain, others filled with meats or vegetables.

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.

Every caucus season, swarms of politicians and journalists descend on Iowa. Inevitably the question arises: Why should this state have so much influence?

This year, one particularly harsh article about Iowa is getting almost as much attention in the state as the candidates themselves. The article, written by Iowa resident Stephen Bloom, raises some old questions about the state's role in selecting the nation's president.

The Justice Department has blocked a new South Carolina voting law, saying it violates the 1965 Voting Rights Act. The state law requires voters to present a photo ID in order to vote. The Justice Department says the law disenfranchises minorities, but the state says it protects against voter fraud. For more, Robert Siegel talks to NPR's Pam Fessler.

In an always-connected world, the line between work and life is often blurred. Now, Volkswagen has announced that it is shutting down after-hours email for German employees who are handed Blackberrys.

The BBC has details:

"Under the arrangement servers stop routing emails 30 minutes after the end of employees' shifts, and then start again 30 minutes before they return to work.

"The staff can still use their devices to make calls and the rule does not apply to senior management.
