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.
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.
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.
On Jan. 9, people in and around Charleston, W.Va., began showing up at hospitals: They had nausea, eye infections and some were vomiting. It was later discovered that around 10,000 gallons of toxic chemicals had leaked into the Elk River, just upstream from a water treatment plant that serves 300,000 people. Citizens were told not to drink or bathe in the water, and while some people are now using water from their taps, many still don't trust it or the information coming from public officials.
Back in 1958, a young biologist at Cornell University made a stunning discovery.
He took a single cell from a carrot and then mixed it with some coconut milk. Days went by and the cell started dividing. Little roots formed. Stems started growing. Eventually, a whole new carrot plant rose up from the single cell.
Imagine if you could perform a similar feat with animal cells, even human cells.
Scientists have reconstructed the genetic code of a strain of bacteria that caused one of the most deadly pandemics in history nearly 1,500 years ago.
They did it by finding the skeletons of people killed by the plague and extracting DNA from traces of blood inside their teeth.
This plague struck in the year 541, under the reign of the Roman emperor Justinian, so it's usually called the Justinian plague. The emperor actually got sick himself but recovered. He was one of the lucky ones.
