Federal Reserve Chairman Ben Bernanke acknowledged that the economy is improving on Wednesday, but he isn't convinced the recovery is self-sustaining. He reaffirmed the Fed's position that the economy will likely need super-low interest rates well into 2014.

Federal health officials have added new safety alerts to statins, a class of drugs used to lower cholesterol levels. The Food and Drug Administration cited rare side effects, including memory loss, diabetes and muscle pain. Robert Siegel talks to Rob Stein about the news.

Former Massachusetts governor Mitt Romney, who narrowly won Michigan's Republican primary on Tuesday, traveled south to campaign in Toledo, Ohio on Wednesday. Ohio holds its primary next week on Super Tuesday.

In defiance of Congress, the Obama administration has issued new rules on how it will comply with a defense law mandating that many al-Qaida suspects be sent into military custody: It will issue waivers in many cases. Meanwhile, the Senate Judiciary Committee held a hearing Wednesday on the trouble with waivers and the need for flexibility in dealing with suspects.

Robert Siegel talks to three former GOP party chairmen and governors about the results of Tuesday's primaries in Michigan and Arizona. Haley Barbour of Mississippi says the campaign should now focus on social issues. Marc Racicot of Montana agrees, but says attention must be paid to those who care about such issues, and Jim Gilmore of Virginia says he feels a connection must be made between the GOP and blue collar voters.

On Wednesday evening, President Obama is expected to host a dinner at the White House honoring veterans of the Iraq War. Veterans still face challenges after their homecoming, including a higher-than-average unemployment rate.

No one ever said economic forecasting was easy:

On the last day of February 2007, Federal Reserve Chairman Ben Bernanke told Congress that "the fundamentals are very strong" for the U.S. economy.

And about those problems starting to show up in the housing market? "We don't see it as being a broad financial concern or a major factor in assessing the course of the economy," he said back then.

That's it. They win. He's giving up his privacy.

Trying to maintain privacy in contemporary America is just too time consuming, too complicated, too exhausting. He can't tell the good guys from the bad guys anymore. He doesn't know whom to trust.

Davy Jones, who thrilled many a young girl's heart back in the '60s as a member of the Monkees, has died.

TMZ broke the news. It reports being told by the medical examiner's office in Martin County, Fla., of the 66-year-old singer's death. The English-born Jones apparently lived in that part of Florida.

The Boston Globe reports this morning that Wall Street Journal reporter Daniel Pearl was baptized posthumously in a Mormon temple in Idaho last year.

Pearl was Jewish and was captured and killed by terrorists while reporting in Pakistan in 2002.

Reuters and The Associated Press are reporting that Egyptian authorities have decided that seven Americans who it has accused of engaging in illegal "political activity" may now leave the country.

Two controversial studies on bird flu will once again be reviewed by an expert committee that advises the government on what to do with biological research that could pose potential dangers.

The move is just the latest development in a fierce ongoing debate about genetically altered flu viruses created in laboratories at Erasmus Medical Center in the Netherlands and at the University of Wisconsin-Madison.

An ominous excerpt from the latest BBC News report on what's happening in Syria:

"The Syrian army is advancing on opposition positions in Homs, which has been under artillery bombardment for nearly a month, reports say. Security officials said the city's besieged district of Baba Amr would be 'cleaned' within the next few hours."

One week after saying "you'll have to ask President Obama" when asked if he believes the president is a Christian, Rev. Franklin Graham has issued an apology for "any comments I have ever made which may have cast any doubt on the personal faith of our president, Mr. Obama."

Writer Nick Flynn was working in a homeless shelter in his 20s when his father – an alcoholic and self-proclaimed writer who left when Flynn was a baby – showed up as a client. Flynn wrote about the experience in his 2004 memoir, Another B------- Night in Suck City.

His story is now a movie called Being Flynn, starring Paul Dano as the young Nick Flynn and Robert De Niro as his father, Jonathan.

On Wednesday's Fresh Air, Nick Flynn and Paul Weitz, the film's director, talk about adapting Flynn's memoir for the big screen.

As a kid, Joy Johnston was Daddy's little girl.

Her father, Patrick, worked in the trucking trade, took care of his family and loved singing to his daughter.

When Joy got older, she moved to Atlanta for work and her parents retired to New Mexico. When she flew in for a visit in 2008, she noticed her father was changing. He would pay for gas but not fill up the tank. He would ask his wife, Jane, "Where's Jane?"

As orchards go, truffle orchards are upside-down and backwards. The magic happens beneath the oak and hazel trees, where a richly flavored mushroom sprouts from fungal colonies laced about the trees' roots. They're called black Perigord truffles, or tuber melanosporum.

These truffles are notoriously hard to cultivate, even in France, where Perigords orginate. Now, in the rolling hills and clay soils of eastern Tennessee and western North Carolina, a growing number of farmers are hoping to establish southern Appalachia as the new truffle capital of the world.

Our brains are filled with billions of neurons, entangled like a dense canopy of tropical forest branches. When we think of a concept or a memory — or have a perception or feeling — our brain's neurons quickly fire and talk to each other across connections called synapses.

How these neurons interact with each other — and what the wiring is like between them — is key to understanding our identity, says Sebastian Seung, a professor of computational neuroscience at MIT.

News that Google will place its dozens of services under one privacy policy — a change that also means the company will compile and collate each user's data from all those products — has some of its customers scrambling to restrict their privacy settings before the new policy goes into effect on March 1.
