Let me take a second here.

Not very long, was it?

But a second tied up delegates to the UN's International Telecommunication Union, who postponed a decision this week on whether to abolish the extra second that's added to clocks every few years to compensate for the earth's natural doddering.

The earth slows down slightly as we spin through space. No one falls off, but earthquakes and tides routinely slow the earth by a fraction of a fraction of a second, which makes clocks minutely wrong. If not corrected, it could make a minute of difference a century.

The race for the 2012 Republican presidential campaign has been anything but predictable.

It's been the first contest in memory, for instance, with a candidate, Mitt Romney, who was reputedly the inevitable nominee but so suspect in many Republicans' eyes that they kept searching for an alternative. That has led to nearly every candidate in the crowded field, at one time or another, challenging for frontrunner status.

The final results for Egypt's parliamentary elections are in, and while there are no surprises, the Muslim Brotherhood exceeded expectations by capturing 47 percent of the vote.

The final election results were read out Saturday with little ceremony, but the final tally cemented what most people in Egypt already know: Islamist groups are the new political powerhouse in post-revolutionary Egypt.

CLAY JOHNSON: You know, our minds are really wired to be affirmed and to be told that we're right. And that's the central premise of "The Information Diet." It's really, who wants to hear the truth when they can hear that they're right?

Under current law, candidates' campaigns are not allowed to coordinate with superPACs, although they clearly benefit from their messages. As result, candidates have performed feats of verbal gymnastics in order to talk about them. Host Scott Simon speaks with NPR's Peter Overby about the role of superPACs in the presidential race.

Conference championship Sunday is almost as big as the Super Bowl, but without all those distracting halftime wardrobe malfunctions. Host Scott Simon is joined by NPR's sports correspondent Tom Goldman to discuss the upcoming games.

SCOTT SIMON, HOST:

This is WEEKEND EDITION from NPR News. I'm Scott Simon, and the polls are open in South Carolina; first southern state to hold a primary in the race for the Republican presidential nomination of 2012, the stakes are critical. The state has picked the eventual nominee in every year since 1980, and it's sure been a turbulent week with Rick Perry dropping out, Iowa declaring Rick Santorum the winner of its caucuses and Newt Gingrich closing in on Mitt Romney.

Police have closed down dozens of toy shops for selling Barbie dolls in Iran, part of a decades-long crackdown against "manifestations of Western culture." Host Scott Simon looks at what's being called a "cultural Trojan horse."
