You can see some progress in Haiti two years since the 7.0-magnitude quake hit. But Port-au-Prince is a tour of unrelenting misery and often disturbing images. Things are happening — slowly. You can tell the pace of progress by looking into people's eyes — emptiness looks back at you. Pain is etched on their faces.

You see it in Elicia Andre. We met her back in December at the homeless encampment run by Catholic Relief Services in Port-au-Prince, where she sought refuge after the quake. The charity had just given her $500 to rent an apartment for a year.

Standard & Poor's downgraded the sovereign debt of France, Italy, Spain and six other European countries on Friday. The move was highly expected, but it's still a blow to France and sending shock waves across Europe. France is the eurozone's second-largest economy, and its downgrade could even threaten Europe's master plan to stop its debt crisis.

There's two stories about space junk today: First, the AP reports that the International Space Station had to fire its engines to move out of the way of some space junk.

"NASA officials said debris from an old U.S. private communication satellite would have come within three miles of the orbiting outpost on Friday had the station not changed its orbit," the AP reports.

The dynamic duo of PBS host Tavis Smiley and professor/activist Cornel West was it again in Washington Thursday evening during a live television broadcast of a program addressing poverty.

The two have made a traveling roadshow out of their roles as the loudest African-American critics of President Obama.

Four years ago, Texas Rep. Ron Paul finished fifth in the New Hampshire presidential primary with just under 8 percent of the vote.

On Tuesday, he got nearly 23 percent of the vote in this year's New Hampshire primary — finishing second to former Massachusetts Gov. Mitt Romney in the Republican contest. That came a week after Paul's third-place finish in the Iowa caucuses.

A year ago today, India saw its last recorded case of polio in an 18-month-old girl in West Bengal named Rukhsar Khatoon. She recovered without lasting paralysis.

One year without another case is an impressive milestone in the decades-long effort to wipe the poliovirus from the face of the planet. Only a few years ago, India reported more polio cases than anywhere else — as many as 100,000 cases a year.

When you open a tub of yogurt, do you pour off that cloudy layer of liquid that collects on the top? If so, you're not just wasting nutritious protein and lactose – you're tossing out what some scientists see as a valuable raw material.

Strange though it might seem, researchers at the Fraunhofer Institute for Process Engineering in Germany announced this week that they're turning whey into plastic-like films.

Bob Jones University used to be a "station of the cross for aspiring presidential candidates," NPR's Ari Shapiro reports on Friday's All Things Considered. Candidates like Ronald Reagan, Bob Dole and Pat Buchanan all spoke at the school, a "bastion of the most conservative brand of evangelical Christianity," Shapiro says.
