A problem with sanctions is they don't always work as intended.

If the U.S. and Europe don't buy Iran's oil, but other countries pick up the slack, for example, nothing is accomplished. Or if some Iranian oil is taken off the market but the price goes up, Iran could earn just as much from its oil even though it is selling less.

Kano, the largest city in Nigeria's Muslim north, is an ancient, sprawling city of more than 9 million. Last Friday, the Muslim day of prayers was shattered by a series of coordinated bomb blasts.

Just down the street from one of the main market areas in the city, the street remains blocked off from a police station hit in the attacks. The radical Islamist sect Boko Haram claimed responsibility.

Sagir Ali, a security guard at a parking lot at the market, says he watched as nearby government offices were attacked.

The practice of hydraulic fracturing — pumping fluid into underground rock to push up natural gas — has its detractors, especially among environmentalists. But it's becoming clear that whatever its drawbacks, "fracking," as it's called, is producing a lot of gas — maybe too much gas.

Fracking was once a small part of the natural gas industry, a technique to get hard-to-reach deposits in underground shale. Then the technology improved, and the dinner bell rang. Everybody wanted in. Now there's so much gas on the market that the price is at a 10-year low.

Now that Joe Paterno has passed on from Happy Valley, we must ponder whether we will ever see his like again.

But please: I am now, you understand, talking about Coach Paterno. Let us, for the moment, put aside how the old citizen whose credo was "Success With Honor" acted with regard to pedophilia: so without sensitivity, so irresponsibly, so –– ultimately –– cold-bloodedly. That will sully Paterno's memory forever.

Americans who've been traveling abroad are all too often stunned by the size of their mobile phone bill. Even if they aren't actively using their phone, they can rack up hundreds, sometimes thousands, of dollars in charges — resulting in what consumer advocates call "bill shock."

Los Angeles resident Lisa French thought she was being careful when she took her smartphone on a trip to Japan.

"I was advised not to make any phone calls, as phone calls oversees are very, very expensive," she says.

When Waterbury, Vt., got walloped by the remnants of Hurricane Irene, the small town sustained an estimated $9 million in damages to personal property, and countless millions more in lost business revenue. Five months later, the waters have receded, but Waterbury's future remains uncertain.

On Main Street, a church bell still chimes every day, but daily life in Waterbury hasn't been the same since Irene.

"It's palpable," says Bill Shepeluk, Waterbury's municipal manager. "You can sense that it's not as vibrant as it was."

We members of the global food village seem to have something in common: We're pretty darned skeptical food manufacturers' health claims.

Newt Gingrich celebrated his win in the South Carolina primary with a fundraising blitz — a two-day push to raise as much money as possible. The campaign says it brought in $2 million. That money will come in handy in Florida. But the need for quick fundraising shows the precarious state of the Gingrich campaign's finances.

Apple's just-released financial results for the quarter ended Dec. 31 have some eye-popping numbers:

-- "Record quarterly net profit of $13.1 billion," double the $6 billion of the same quarter a year earlier.
