Students wait to pass through a security checkpoint at the University of Pittsburgh's Cathedral of Learning on Tuesday. Security has tightened at the school after a string of false bomb threats on the campus.
Since mid-February, the University of Pittsburgh has received more than 50 bomb threats, and while they've all been false alarms, they have succeeded in disrupting campus life. Tighter security measures are now in place, but the threats continue, and students are wondering how they'll be able to make up class work and prepare for final exams.
A concert in Pyongyang in February 2012 commemorates the birthday of North Korea's late leader, Kim Jong Il. The backdrop shows a North Korean rocket that was launched in April 2009 — and was followed a month later by a nuclear test.
As North Korea reaches the final stage of preparations for a long-range rocket launch, concern is growing that it is in the early stages of preparing its underground test site for another nuclear explosion.
Pyongyang established the pattern three years ago when it tested a similar rocket and then followed it a month later with a nuclear test.
This time around, there may be a more urgent need to test a nuclear device. The bomb is very likely the result of a significant expansion of North Korea's nuclear weapons program.
President Obama has a chance to make fun of his opponents — and himself — when he addresses the annual White House Correspondents' Association gala later this month. Last year he joked about Donald Trump and the "birther" issue.

Former Massachusetts Gov. Mitt Romney laughs while addressing supporters at his Super Tuesday campaign rally in Boston on March 6.
At the end of the month, President Obama will deliver a string of punch lines at the White House Correspondents' Dinner. It's an annual tradition, a chance for the man at the top of the pyramid to poke fun at his political opponents and himself.
Humor is an essential tool in any politician's kit — all the more so in an age of instant, constant media. It can disarm an opponent, woo a skeptical voter or pierce an argument. This year, both Obama and presumptive GOP nominee Mitt Romney are using it to try to win the upper hand in the presidential race.
A fisherman uses a lantern while dip-netting for elvers on a river in southern Maine. Elvers are young, translucent eels that are born in the Sargasso Sea and swim to freshwater lakes and ponds, where they grow to adults before returning to the sea.

Fishermen in Maine and South Carolina are reaping profits upward of $2,000 per pound for elvers.
There's a gold rush under way on the East Coast of the U.S. for tiny baby eels known as elvers. Fishermen in Maine and South Carolina are reaping profits upward of $2,000 per pound for the fish that are considered a delicacy in Japan.
Elvers have an almost ghostly appearance in the water — their bodies are a cloudy white, skinny as a cocktail straw and no longer than your finger. They look like tiny snakes as they squiggle through the water.

Convicted murderer Charles Manson, sentenced to life in prison for his role in the grisly deaths of seven people in 1969, will not be released from prison, California's parole board decided Wednesday. The hearing, which Manson did not attend, may have been the 77-year-old's last chance at freedom. His next bid for a parole hearing isn't likely to be heard until 2027.

The U.S. Food and Drug Administration said today it is calling on the nation's pork, beef, and poultry producers to reduce their use of antibiotics. But some watchdog groups say this voluntary guidance doesn't go nearly far enough.
The issue has been contentious for decades. Just last month, a federal judge ruled that the FDA had to go ahead with a plan it proposed in 1977 that would ban the use of some antibiotics as a growth promoter in animals.

The bulk of the U.S. military force in Afghanistan is slated to leave the country by 2014. But the Pentagon is willing to keep some Americans there to train Afghan forces, according to a report by NPR's Tom Bowman.
Here's Tom's report for NPR's Newscast:
"Afghan Defense Minister Adbul Rahim Wardak says his country is looking for an enduring long-term relationship with the United States. And part of the relationship centers on training and equipping Afghan soldiers and police."

North Koreans in Pyongyang rehearse for the commemoration of the 100th anniversary of Kim Il Sung's birth on April 15.
As North Korea gears up to launch a long-range rocket, political changes are afoot, too: Pyongyang has consolidated its succession process, giving a new title to its new leader, Kim Jong Un, who came to power in December after his father's death.
The rocket launch, which could come as early as Thursday in North Korea, has been condemned by the international community as being in violation of U.N. Security Council resolutions. So why now?
The fallout from the consumer backlash to so-called "pink slime" continues to hurt meat sales. Now, some companies are taking steps to label the product they call "lean, finely textured beef" in hopes that they can earn back consumer trust.
Tyson and Cargill, two multinational firms that sell ground beef containing the processed trimmings, say they have submitted labeling requests to the U.S. Department of Agriculture in hopes that some customers will feel better about buying ground beef containing LFTB if it's labeled.
The Federal Reserve's policymakers seem to be reluctant to consider any more efforts to inject a monetary stimulus into the U.S. economy — but that doesn't mean you should expect the central bank to raise interest rates any time soon.

After hearing that football coach Bobby Petrino had not only lied about who he was with when he had a motorcycle accident on April 1, but that he was also having an affair with that young woman, had paid her $20,000 and had arranged for her to get a job with the university, Arkansas Razorbacks fans are saying they agree with the decision to fire him.
For President Obama, the Buffett Rule is the political equivalent of a Swiss army knife, a tool he clearly intends to use any number of ways as he fights to be re-elected and deny the White House to Republican Mitt Romney.
From the Democrats' perspective, the proposed rule, which would require that superwealthy taxpayers with at least $1 million in taxable income after deductions, pay taxes at a minimum 30 percent rate, has so much going for it, they can hardly stop talking about it.

Silver chalices made in Syria in the sixth or seventh century. They are known as the Attarouthi Treasure, named after the prosperous Byzantine merchant town of Attarouthi.
The yearlong tumult of the Arab Spring has reached all the way to the Metropolitan Museum of Art in New York.
A stunning and timely new show, "Byzantium and Islam: Age of Transition," covers exactly the places caught up in modern day revolts, and many of the developments from more than a millennium ago are closely linked to the events of today.
As al-Jazeera and other news outlets report being told by activists that Syrian government forces are shelling the city of Homs and attacking and arresting opponents of President Bashar Assad in other places, former U.N. Secretary General Kofi Annan continues to press for a true ceasefire to take effect on Thursday.
