The digital age has taken its toll on another long-held tradition: Encyclopaedia Britannica is going out of print and from now on will be all digital.
Its final printed product will be the 2010 edition, which The New York Times describes as a "a 32-volume set that weighs in at 129 pounds and includes new entries on global warming and the Human Genome Project."
With two wins in the Deep South, Mitt Romney could solidly establish himself as the inevitable GOP candidate. If you believe polls, that could very well happen in Mississippi and Alabama, which are holding nominating contests tonight.
Now, the polls are so close that Rick Santorum and Newt Gingrich could also pull together wins that keep their campaigns going.
"We did it again," declared Rick Santorum during his victory speech in Lafayette, La.
Indeed, the former Pennsylvania senator swept the Republican presidential primaries in Alabama and Mississippi and once again threw Mitt Romney, who has from the very beginning been the presumptive nominee, on the defensive.
Of course, there are two other contests going this evening: Hawaii and American Samoa are holding caucuses, and if Romney takes both of those, he may very well end the night with the most delegates.
The Federal Reserve has released the results of its much-anticipated stress test of the nation's biggest banks. The Fed says most of the nation's 19 biggest financial institutions passed the tests, although four did not. To find out what this means, we turn to NPR's Jim Zarroli. Jim, first, why is the Fed running stress tests? What are they supposed to show about the banks?
Los Angeles has become the nation's first city to require male adult film actors to wear condoms. The city council's new ordinance has riled the region's billion-dollar-plus porn industry. Filmmakers are warning that the measure will harm the local economy and threaten the health of industry performers.
Condoms are now required on all film shoots that receive a city permit, but the law does not apply to adult films shot in studios. Those don't require city permitting in the first place. But a proposed ballot measure in November looks to extend the law throughout the county.
The documentary Bully follows several middle- and high-school students who are different, awkward or for some other reason the targets of bullying. One of the kids at the center of the film is Alex, from Sioux City, Iowa.
In the film, Alex, a small boy, says people think he's not normal, and most kids don't want to be around him. And some kids at his school, or on the school bus especially, make his life miserable.
Director Lee Hirsch says Alex immediately struck him as someone who was having a hard time — and no one seemed to notice or really care.
As part of a new campaign, dozens of citizen groups around the country are searching voter registration lists, looking for problems.
They're also training poll watchers to monitor this fall's elections.
Leaders of the effort — spawned by the Tea Party movement — say they want to make sure that elections are free from voter fraud. But critics say it's part of a campaign to suppress the votes of minorities, students and others who tend to vote Democratic.

Computer screens at the Birmingham office of the National Weather Service show forecast models. Meteorologists use the information to predict severe weather. During Alabama's tornado outbreak on April 27, 2011, forecasters were forced to take shelter when one of the twisters came close to their offices.
For many, the only way they learn a tornado is approaching are sirens. In the spring and summer, tornado sirens go off a lot more when twisters roar across Alabama, which has been hit by 900 since 2000, accounting for a quarter of all U.S. tornado deaths.
"I am still surprised that so many people rely on just one source of getting warned, and that has to change," said Jim Stefkovich, meteorologist in charge of the Birmingham office of the National Weather Service.
