If you pick up a cushion from any sofa or piece of furniture that has foam, you're likely to find a small white tag that reads: "This article meets all flammability requirements of California Bureau of Home Furnishings technical bulletin 117."

The law, referred to as TB 117, was passed in California in 1975. It says that the foam inside upholstered furniture must be able to resist a flame, such as from a cigarette lighter or a candle. Rather than make different furniture just for California, big furniture makers adhere to those standards in all 50 states and even Canada.

The Olympics start in July, but American sprinter Allyson Felix is still deciding which events she'll focus on in London. She's won Olympic silver medals twice in her beloved 200 meters, a distance in which she's also a three–time world champion.

Felix won an Olympic gold in 2008, on the 4x400-meter relay team. But this time around, she wants an individual gold, too.

New Success At 100 Meters

Xerox is one of America's most venerable companies. Founded in 1906, its name is virtually synonymous with "photocopy."

But in recent years, in an era of email and paperless offices, Xerox has struggled to stay relevant. Today, the company is trying to turn itself around and thrive in the digital age.

Leading Xerox through that transformation is Ursula Burns, a woman who has undergone tremendous change in her own life. Burns, 53, grew up in New York City's Lower East Side, an area she has described as a tough, drug-infested ghetto.

Pom Wonderful Pomegranate products may be loaded with antioxidants, but there's not sufficient evidence that it can treat, prevent, or reduce the risk of specific conditions such as heart disease or erectile dysfunction according to a ruling handed down by Chief Administrative Law Judge Michael Chappell.

A big study of a colon cancer test called flexible sigmoidoscopy may provide a good example of how a cheaper, easier-on-the-patient and possibly better technology isn't always the one American doctors choose to use.

On Tuesday, family and loved ones in Chowchilla, Calif., remember a school bus driver who many consider an American hero. Thirty-six years ago, Ed Ray was driving his regular school bus route when it was hijacked. Everyone aboard was driven 100 miles, forced into a storage van, and buried alive. Audie Cornish speaks with Lynda Carrejo-Labendeira, who was on the bus that day.

While we assume our judicial system occasionally makes mistakes, until recently no one had been tracking the number people in this country who are convicted and later exonerated. Now the National Registry of Exonerations has begun compiling these cases. Audie Cornish talks with the registry's editor, Samuel Gross, about some of the group's findings from the over 2,000 exonerations they've compiled.
