Cinema owners who don't have a digital projector in their movie house can't show Paramount Pictures' latest release: The Wolf of Wall Street. This year Paramount became the first big studio to distribute a major release in the U.S. entirely in a digital format, and other studios are likely to follow.

Your Nose Knows Which Foods Are Fattiest

A lot of us can agree that low-fat ice cream is a sad substitute for the real deal. It's not as creamy, and it just doesn't taste as good.

Now researchers are saying it may even smell different.

Researchers from the Monell Chemical Senses Center have found that people can actually smell differences in dietary fat in food.

There's new evidence that widely prescribed testosterone drugs — touted for men with flagging libidos and general listlessness — might increase the risk of heart attacks.

A study of more than 55,000 men found a doubling of heart attack risk among testosterone users older than 65, compared with men who didn't take the drug.

The Starling That Dared To Be Different

You've seen them. We've all seen them.

Hundreds of starlings are sitting side by side by side — up on a power line yakking, preening — when all of a sudden, boom! Up they go, all of them. What happened? A sudden noise? A falcon in the neighborhood? Whatever it was, all the birds know. All the birds go. Starlings find safety in numbers. They like sameness. Exceptional starlings, I imagine, get eaten.

Well, that's what I used to think. Then, today, I saw my first unlike-all-the others starling. At least I think I did.

New York could soon become the first state in the nation to write comprehensive regulations for the largely lawless world of virtual currencies.

The biggest one, Bitcoin, has many boosters, but it has also been connected with some spectacular crimes. On Monday, federal prosecutors announced the arrests of two men accused of using Bitcoin to help their clients buy and sell over $1 million in illegal drugs.

The asteroid belt, a ring of rubble between Mars and Jupiter, has sometimes been written off as discarded leftovers from the solar system's start. But new research published in the journal Nature shows that the belt actually formed during an unruly later era, when planets themselves were on the move.

Much Of North Dakota's Natural Gas Is Going Up In Flames

A remarkable transformation is underway in western North Dakota, where an oil boom is changing the state's fortunes and leaving once-sleepy towns bursting at the seams. In a series of stories, NPR is exploring the economic, social and environmental demands of this modern-day gold rush.

North Dakota's oil boom isn't just about oil; a lot of natural gas comes out of the ground at the same time. But there's a problem with that: The state doesn't have the pipelines needed to transport all of that gas to market. There's also no place to store it.

A lot of parents like to think their kids will simply outgrow baby fat. But the risk of becoming a severely overweight adult can actually start as early as kindergarten, research suggests.

"As parents, as a society, as clinicians, we need to think about a healthy weight really early on," says Solveig Cunningham, who led the study. But that doesn't mean putting young children on calorie-restricted diets.

Neanderthal Genes Live On In Our Hair And Skin

Originally published on Thu January 30, 2014 10:11 am

Neanderthals died out long ago, but their genes live on in us. Scientists studying human chromosomes say they've discovered a surprising amount of Neanderthal DNA in our genes. And these aren't just random fragments; they help shape what we look like today, including our hair and skin.

These genes crept into our DNA tens of thousands of years ago, during occasional sexual encounters between Neanderthals and human ancestors who lived in Europe at the time. They show up today in their descendants, people of European and Asian descent.

A Milk Mystery: Did Gloomy Weather Make Us Love The Stuff?

A new study on lactose tolerance among early farmers in Spain challenges a leading theory that humans developed an appetite for milk to avoid calcium deficiency.

Humans have a love-hate history with milk.

For thousands and thousands of years, adults couldn't digest dairy products without an upset stomach and a trip to the bathroom.

And then one day, poof!

A few changes in our DNA gave about a third of the world's population – mostly Europeans — the ability to knock back cheese, pizza and chocolate ice cream without a care in the world.

But why? Why did this ability to digest lactose suddenly crop up in our European ancestors about 10,000 years ago? That's been a big mystery for scientists.
