This upcoming weekend, a team of German explosive experts and members of the army are scheduled to defuse an unexploded bomb found in the city of Koblenz in Germany. The bomb — with 3,000 pounds of explosives — is a remnant of World War II that emerged in the Rhine River because of low water levels.

As if that wasn't curious enough, authorities ordered half of the city's residents — 45,000 people — to leave, while they get the job done.

Der Spiegel reports:

Keeping off the pounds is tough at any age. Now seniors are getting a helping hand from the Centers for Medicare and Medicaid Services, which has announced that it will cover screening and counseling for obesity as a free preventive service for Medicare beneficiaries.

A new Pennsylvania law could curb municipalities' ability to zone and regulate hydraulic fracturing — or "fracking." And that raises questions about how much say a local government should have over what goes on within its borders.

State lawmakers are grappling with how to update Commonwealth's decades-old Oil and Gas Act to catch up with a natural gas drilling boom.

For the past few years, the travel site Expedia has conducted a survey about the world's vacation habits and like in years past, this year's survey found that the United States is one of the countries that gives its workers fewer vacation days and one of the countries in which workers leave the most number of vacation days unused.

CNN Money reports:

The U.S. economy is experiencing its strongest across-the-board growth of the year, as private companies hire more people, some manufacturers expand and the stock market surges on a plan to ease Europe's financial crisis. The Dow Jones industrial average gained 490 points Wednesday, an increase of more than 4 percent.

But analysts say the economy isn't growing robustly enough to lower unemployment, stem government layoffs or revive a housing market that remains extremely weak.

Newt Gingrich traveled across South Carolina this week appearing at a number of town-hall-style meetings where he talked to voters and answered questions — mostly the same questions at every stop. He talked about the improving the economy, creating a new immigration policy, repealing President Obama's health care reform plan and transforming Washington.

This is a pretty heartbreaking story: An 80-year-old man donated a suit to a Goodwill store in western Illinois. The problem is that he didn't realize until it was too late that his $13,000 life savings were in the suit's pocket.

The AP reports:

The major central banks of the world moved Wednesday to prevent a banking crisis in Europe. They're providing more liquidity to the European banking system in hopes that big banks there will remain solvent and continue to make loans. The coordinated move by the central banks sent stock markets soaring. But it will not even begin to fix Europe's fundamental economic problems.

Melissa Block and Guy Raz read emails from listeners about a report on Kentucky's Berea College, about Melissa's remembrance of Vermont poet Ruth Stone, and about the other person responsible for that mega-hit earworm "Moves Like Jagger."

Guy Raz talks to Felix Salmon, a finance blogger for Reuters. Salmon explains Wednesday's actions by six central banks to improve access to U.S. dollars internationally.

In Chicago, city officials and demonstrators say the recent Occupy Chicago protests are a sort of dry run for next year's simultaneous NATO and G-8 summit meetings.

Secretary of State Hillary Clinton is in Myanmar, also known as Burma, to see if the county's leaders are serious about political reform. Myanmar has long been under international sanctions because of the repressive nature of the military junta that held power until recently. But there are signs that a new civilian government is loosening the military's grip.

Can you say blip?

Apparently that's what last month's all-time low popularity numbers were for President Obama's health overhaul law, according to this month's tracking poll by the Kaiser Family Foundation.

Overall, the federal Affordable Care Act still remains slightly more unpopular (44 percent) than popular (37 percent), but that's down from last month's 51-34 split.

The Justice Department says the man who shot and wounded President Ronald Reagan in 1981 still poses a threat to public safety.

Prosecutors are fighting an effort by John Hinckley to win more freedom from a mental hospital where he's been confined for decades.

During a hearing in Washington, the prosecutors said the government has been watching Hinckley.

Secret Service agents followed Hinckley last summer, when he said he was going to the movies during visits to his mother's home in Williamsburg, Va.

The first civil lawsuit brought by an alleged victim of Jerry Sandusky is from a man who says he was sexually abused as a young boy more than 100 times by the former Penn State assistant football coach.

Vita Lee has lived in her Northwest Atlanta home for 53 years. But after a second mortgage was taken out on her home, she faced foreclosure and police planned to evict her yesterday.

But as Atlanta's WSB-TV reports, once Fulton County sheriff's deputies and the movers looked at the 103-year-old Lee, they declined to move forward with the eviction.

These new technologies are "challenging our Constitutional categories in really dramatic ways," says George Washington University law professor Jeffrey Rosen. "And what's so striking is that none of the existing amendments give clear answers to the most basic questions we're having today."

The United States is doing a pretty miserable job of treating people with HIV.

The latest numbers show that only 28 percent of the nation's 1.2 million HIV-infected people are getting effective treatment — that is, antiviral medications to keep the virus in check.

When you buy food that is labeled fair trade, you do so to support farmers who meet certain social and environmental standards. But some companies now disagree about whether a new take on fair trade can really be called "fair."

Leading central banks around the world took coordinated moves Wednesday to provide more liquidity in the global financial system and calm rising fears in Europe over access to credit. As Europe's sovereign debt crisis worsens, bank lending has tightened, and nervous investors are reluctant to make loans to European banks.

Republican voters may have saved the best for last in terms of the latest obstacle they've placed between Mitt Romney and what was supposed to have been his inevitable march to the 2012 Republican presidential nomination — Newt Gingrich.

Essentially written off after his campaign seemingly imploded last summer and because of the manifest personal baggage he brings to a presidential campaign, Gingrich stuck around long enough to have his moment, to catch fire after Herman Cain flamed out.

Police in two of the nation's largest cities moved in overnight to sweep away the camps of Occupy protesters. In Philadelphia, protesters marched through the streets; about 50 were arrested.

Steve Inskeep talks with Frank Stoltze of member station KPCC, who was been watching the developments in L.A.

Now, the Occupy protests have focused on economic issues, which are also motivating a massive strike in Britain today. It is being described as the largest national strike in a generation. It is estimated that as many as 2 million public sector workers may be taking part, the latest in a wave of protests over austerity measures.

NPR's Philip Reeves is covering that story in London. And Philip, where are you?

The Federal Reserve joined other major central banks Wednesday in a coordinated effort to shore up the global financial system. The move comes at a time when credit is becoming tighter, especially in Europe, because of doubts about the health of big banks.

A Democratic state representative in Arizona thinks it's wrong for a Scottsdale gun club to be giving folks, including children, a chance to have their photos taken with Santa Claus while "holding pistols and military-style rifles," The Associated Press says.

State Rep. Steve Farley says "to involve machine guns and Santa in a celebration in the birth of Jesus Christ is the worst kind of heresy I can imagine."
