One of the guests in the congressional gallery at last week's State of the Union address was Roxana Delgado, an advocate for soldiers returning home with traumatic brain injuries. Her husband, an army sergeant who NPR profiled in June, 2010, had been dramatically affected by the concussion he received from a roadside blast in Iraq.

Many investors are expecting Facebook to file papers for an initial public offering sometime later this week. The company, which was founded in a Harvard dorm room less than a decade ago, is expected to be valued at nearly $100 billion by Wall Street.

And if these early reports are true this is shaping up to be the biggest Internet IPO ever.

Republican presidential hopeful Newt Gingrich is changing another of his positions in an effort to woo socially conservative voters.

Over the weekend he told churchgoers in Florida that as president he'd work to ban research using stem cells derived from human embryos.

Gingrich has long been a strong backer of federal funding for scientific research. In 2001 his support extended to research on stem cells derived from human embryos left over from in vitro fertilization efforts.

But apparently that's no longer the case.

Talk about lost in translation: Today's British press is buzzing with a story in the British tabloid The Daily Mail, which reports that two British travelers were denied entry into the U.S., after authorities uncovered two tweets.

In one Leigh Van Bryan quipped, "Free this week, for quick gossip/prep before I go and destroy America." And in another Van Bryan said that he was going to "dig up Marilyn Monroe."

If creatures from another planet are listening in on what our politicians and pundits have to say, they might think Democrats and Republicans are about as far apart politically as possible.

But there's new research that supports what many people already suspect: Most "real" Republicans and Democrats (that is, average Americans who have busy lives and aren't running for office or talking on TV), aren't that different when it comes to politics.

With Mitt Romney poised to win the Florida Republican primary, and maybe by a significant margin if the latest polls are correct, it's worth asking: how did the former Massachusetts governor manage to stop Newt Gingrich's surge coming out of South Carolina?

As reports come in about an escalation in fighting around Damascus and the deploying of army troops in the city's suburbs, the State Department just announced that Secretary of State Hillary Rodham Clinton will go to the United Nations on Tuesday to join other nations in condemning the Assad regime's use of violence.
