Parts of Nigeria are under a 24-hour curfew, after demonstrations against a government policy to end fuel subsidies turned into a fiery rampage in the city of Minna. The BBC reports that "hundreds of rioters set fire to government and political party offices and also targeted the homes of local politicians."

The AP lays out the basics of how we got here:

Did pollsters underestimate the strength of Rep. Ron Paul's New Hampshire support because they didn't include enough younger voters or independents in their samples?

Yes, argues Stefan Hankin, a Washington, D.C. based pollster in a piece on the Campaign and Elections website.

As we've said before, to figure out what the Federal Reserve means when it reports about how the economy is doing and whether policymakers think it's doing better or worse, you need to carefully compare the central bank's latest words to what it has said in preceding months.

U.S.-Pakistan ties are virtually frozen. And now, relations between Afghan President Hamid Karzai and Washington are once again getting frosty.

Over the weekend Karzai surprised the Americans with the demand that the largest U.S.-run prison be turned over to Afghan control much sooner that planned.

It's the latest in a series of announcements by the Afghan government that sometimes appear designed to embarrass and annoy U.S. officials, as well as complicate American plans to withdraw troops from Afghanistan.

Nicotine patches and gums have been helping smokers quit for decades. Right?

Even President Obama, once the Smoker in Chief, has kicked the habit with the help of nicotine replacement therapy, according to his doctor's latest report.

After a third-place finish in New Hampshire, the state he poured his heart and soul into and placed all his bets on, Jon Huntsman doesn't need any more bad news. Just a cursory look at the headlines, and you find they're mostly talking about the end. Even the Christian Science Monitor doesn't mince words, asking, "Is Jon Huntsman toast?"

An explosion in Tehran Wednesday killed an Iranian nuclear scientist while he was driving his car. It's the fifth such death in five years, and Iranian officials immediately blamed Israel. The attack is the latest manifestation of escalating tensions between Iran and the West.

When Pope Benedict XVI goes to Latin America in March, Mexico is an obvious choice with nearly 100 million Catholics.

But communist-run Cuba is also on his itinerary. The 84-year-old pontiff does not travel often, and this leg of his trip will be a strong show of support for Cuba's church leaders and their growing role in pushing President Raul Castro's government for change.

More than anywhere else in Cuba, the Santa Rita church in Havana's Miramar district is the place where religion and politics intersect.

Tuesday was an exciting night for Mitt Romney in New Hampshire. In mid-Ohio, not so much.

By about 9 a.m. Wednesday, the bankruptcy of a local barbecue restaurant chain was one of several stories ranked higher in the "most popular stories" list on The Columbus Dispatch's website than anything coming out of the GOP primary.

For many people, the election so far just hasn't been that interesting — and it might be even less so if Romney again rakes in the chips in South Carolina next week, adding to the perception that his nomination is virtually a done deal.

Computer chips and technology are invading all sorts of previously dumb devices. Phones are now smart. Cars are becoming connected computers on wheels. Call it the computerization of everything. But how we interact with these machines is bound to evolve.

At this year's Consumer Electronics Show in Las Vegas, touch pads are everywhere — in phones, in tablets and laptop screens. And Brad Feld has had enough.
