One in every four Americans receives their news digitally from mobile devices, which are helping to expand the consumption of journalism across multiple sources, according to a new report released Monday.

The 2012 State of the News Media Report, conducted by Pew Research Center's Project for Excellence in Journalism, provides an in-depth examination of how Americans read news as their consumption habits transition from the printed form to the digital.

Four years since they first began making music together, the Brooklyn-based duo Tanlines is finally releasing an album: Mixed Emotions, out tomorrow. The band is Eric Emm, who sings and plays guitar, and Jesse Cohen, who plays drums, keyboards and an assortment of electronic instruments. Cohen is also the chattier of the two.

"We use a lot of different drum kits that are in a computer," Cohen explains. "We also play a lot of stuff live, and a lot of time you can't really tell which is real and which is fake. That's sort of a thing that we like to play with."

When the Supreme Court hears arguments over President Obama's health care law next week, one item on the table will be a program that has been in place for nearly 50 years.

Medicaid, a joint federal-state program that provides health care for the poor, was signed into law by Lyndon Johnson. Under the Affordable Care Act, it will be greatly expanded and provide coverage for millions of uninsured, including low-income adults without children.

Only 7 percent of plastic waste in the United States is recycled each year, according to the Environmental Protection Agency. A startup company in Niagara Falls says it can increase that amount and reduce the country's dependence on foreign oil at the same time.

It all starts with a machine known as the Plastic-Eating Monster. Thousands of pounds of shredded milk jugs, water bottles and grocery bags tumble into a large tank, where they're melted together and vaporized. This waste comes from landfills and dumps from all over the United States.

Don Draper, the main character on the hit TV show Mad Men, is said to have been inspired by a real Madison Avenue ad man: George Lois. Lois was a leader in the "Creative Revolution" in advertising during the 1950s, and became one of the most influential art directors in advertising history. His work helped make brands like Xerox, Lean Cuisine and Jiffy Lube famous. Lois is perhaps best known for creating iconic Esquire magazine covers, many of which now reside in the Museum of Modern Art.

The next primary election takes place in President Obama's home state of Illinois on Tuesday. While Republicans are looking to capture delegates in the presidential race, there are several House races on the ballot — mostly due to redistricting.

In one of the most closely watched of those races, U.S. Rep. Jesse Jackson Jr. is facing a challenge from fellow Democrat and former Rep. Debbie Halvorson.

With Greece entering its fifth year of recession and dealing with harsh austerity measures imposed as part of a eurozone bailout deal to save it from default, its society is in upheaval. Opinion polls suggest the old political system is collapsing, and extremist parties are gaining popularity ahead of spring elections.

At a recent protest in Athens, a large bronze bell tolled as thousands of policemen in full uniform marched solemnly through the streets. They ominously waved their handcuffs at Parliament, shouting, "Take your bailout plan and get out of here."

When Susy Mansfield needed a hip replacement in 2009, her orthopedic surgeon chose a relatively new and untested kind of artificial hip made entirely of metal.

"He said, 'You're young. Metal is good for younger people. It's going to last a lot longer,' " says Mansfield, who was 57 at the time.

Two eras clash on Monday at the U.S. Supreme Court, when a law written in 1939 is applied to in vitro fertilization. At issue is whether children conceived through in vitro fertilization after the death of a parent are eligible for Social Security survivors benefits.

At least 100 such cases are pending before the Social Security Administration.

And I'm Steve Inskeep. Welcome, David.

There's a protest planned for this morning outside the courthouse in Sanford, Florida. People say they want justice for the family of Treyvon Martin. Last month, that black teenager was shot by a white neighborhood watch volunteer. The shooter says he acted in self-defense, although the teen he shot was unarmed. And newly released recordings of 911 calls offer painful details of the killing.

We've spent much of the weekend trying to understand a nightmare moment of the U.S. presence in Afghanistan. An American soldier apparently walked off his post and killed 16 Afghan men, women and children. Staff Sergeant Robert Bales - we know his name now - is being held in solitary confinement in Fort Leavenworth, Kansas. NPR Pentagon correspondent Tom Bowman has been gathering details of the shooter's life, and he's on the line now. And, Tom, what have you learned?

We are sorry to report that Lehigh is out of the NCAA tournament. They lost in the second round after a huge upset of Duke in the first. Murray State is gone, too.

But as the tournament gets down to 16 teams, one of those teams is Ohio University. Traditionally not one of the powerhouse teams we talk about year in, year out. In fact, it's been more than four decades - 48 years to be precise - since the school has made it this far in the tournament.

NPR's Mike Pesca reports on the team's quest.

U.S. officials think that this may finally be the time that economic sanctions against Iran will start to have a major effect. The U.S. and its European allies have been hoping that tighter and tighter sanctions will push Iran to negotiate an agreement over the future of its nuclear program. Israel has said it can't wait forever before ordering a military strike, but U.S. officials believe that the sanctions can produce results. Here's NPR's Tom Gjelten.

Former House Speaker and presidential candidate Newt Gingrich has been calling his opponent Mitt Romney the weakest front-runner in modern times.

On CNN, he clarified it when he said the former Massachusetts governor is probably the "weakest front-runner since Leonard Wood in 1920."

So, who was Leonard Wood?

There's a number hovering around the GOP presidential race: 1,144. That's the magic number of delegates needed to secure the party's nomination.

Former Massachusetts Gov. Mitt Romney has a little less than half that number right now, but he's still ahead of his closest rival, former U.S. Sen. Rick Santorum.

Santorum is a threat, however, so the two candidates seem to be sharpening their math skills.

When Philip Seymour Hoffman took the stage on March 15 in the new revival of Arthur Miller's Death of a Salesman, he became the fifth actor in 63 years to walk the boards of Broadway in the shoes of the blustery, beleaguered salesman, Willy Loman. In the last six decades, each incarnation of the play has resonated with a new generation of theatergoers.

Typically, college newsletters aren't thrilling reads, but an article in a recent University of California, Berkeley, newsletter tells the story of two alums who connected in way fit for a movie.

It starts in 1949, after Betty Werther graduated from Berkeley. As a graduation gift, her grandmother sent her to Europe with a friend. They traveled to Paris, ostensibly to study at the Sorbonne.

Their studies didn't last long. Werther and her friend strapped on backpacks and hit the road.

Things are looking pretty good at the Dodgers spring training complex in Glendale, Ariz. They have Cy Young Award winning Clayton Kershaw anchoring their pitching staff and at the plate, the National league MVP runner-up, Matt Kemp.

"Hopefully, we can start out the way we finished last year and be consistent throughout the whole year," Kemp said.

Everyone has had enough of what's been happening off the field.

For thousands of years, dogs have been our companions. After countless generations of selective breeding, they've become hard-wired to follow human commands: sit, lie down, jump, even shake.

So far, most other animals don't come close. But what if they could?

In 1954 a Russian geneticist named Dmitry Belyaev wanted to isolate the genes that make dogs so easy to train. He started a fox farm in Siberia and set out to do with foxes in one lifetime what took dogs thousands of years.
