Interest in natural gas vehicles soared in the 1990s and then faded. Twenty years later, the cost of gasoline is going up while the cost of natural gas is going down. And that difference in price explains the resurgent interest in natural gas vehicles.

In Indiana, Fair Oaks Dairy Farm does more than just produce milk — it is also in the transportation business. The farm owns 60 trucks, which deliver milk to a processor halfway across the state. Last September, most of the trucks were converted to natural gas.

Greece has taken almost all the action needed to secure a second bailout from eurozone countries, according to the head of the European currency group. The first loan can now be paid out by March 20, as long as Greece completes a bond swap between Athens and private investors, which should cut the nations privately-held debt in half.

David Greene talks to materials chemist Donald Sadoway from the TED (Technology, Entertainment and Design) conference in Long Beach, Calif. Sadoway is the co-inventor of the liquid metal battery. It's inexpensive, super efficient, sustainable and can provide large scale energy storage.

The district of Baba Amr in the city of Homs had been the heart of the Syrian uprising, where mass protests turned into an armed resistance. Activists say government troops are combing the area, arresting any male over the age of 12.

This is MORNING EDITION, from NPR News. I'm Renee Montagne.

The next big day for Republican presidential hopefuls is Super Tuesday. But on the way to Tuesday, the candidates are making stops in Washington state. Republican caucuses there are set for tomorrow morning.

And as NPR's Martin Kaste reports, with the fight for the nomination still tight, for once the caucuses in Washington state may actually mean something to the presidential race.

Budget cuts approved by Congress in the past two years are trickling down to local communities, and officials there are not happy. They say that reductions in community development block grants will hurt the nation's most vulnerable neighborhoods.

Two years ago, the federal government gave out about $4 billion in such grants to low- and moderate-income communities. This year, the figure is $3 billion — a 25 percent cut. And as that pie has shrunk, those whose slices have shrunk even more are hungry for answers.

Many religious traditions stress the importance of charity. But Mormons are remarkable for the amount and the precision with which they give to their church.

The Church of Jesus Christ of Latter-day Saints teaches that each Mormon in good standing should tithe 10 percent of his or her income. The money goes right to church headquarters in Salt Lake City and then is distributed back to congregations around the world.

"That's written in stone, and preached from the pulpit," says Gordon Dahl, an economist at the University of California, San Diego, who is Mormon.

U.S. District Judge Richard Cebull says he will apologize to President Obama and ask for a panel of judges to investigate his conduct after a Montana newspaper reported he had sent a racially inflammatory message using his courthouse email account last month.

The Great Falls Tribune reported the judge had forwarded the following message to six of his friends February 20:

A panel of three judges from an Atlanta federal appeals court decided Thursday to put off action on lawsuits against measures in Alabama and Georgia. Oral arguments are set for April 25 before the Supreme Court over the constitutionality of Arizona's enforcement policy.

Prosecutors have officially charged 17-year-old T.J. Lane in the shooting rampage at an Ohio high school.

The charges — three counts of aggravated murder, two counts of aggravated attempted murder and one count of felonious assault — were filed in juvenile court, but the AP adds that this could be the first step toward charging him as an adult.

A hearing is set next week in Geauga County to determine whether he'll be charged as an adult.
