Communities around the world are increasingly overrun by invasive critters. Gray squirrels, which are native to North America, are an ecological nuisance in England. And nutria — or swamp rats, colloquially — from South America are destroying wetlands in the Gulf Coast states.
The physical condition of England's King Richard III has been a subject of debate for centuries. Now scientists say 3-D skeletal modeling shows the monarch who lived 500 years ago had a common form of scoliosis and that he's been a victim of spin on a historic scale.
There are lots of entrepreneurs who would love to fly drones — tiny unmanned aircraft — all over the country. They dream of drones delivering packages and taking photos, but there's a battle in the courts right now standing in their way. The battle is about whether it's legal for drones to take to the sky.
The question at the core of the battle: Who owns the air?
You might call it the ultimate long shot — a group of space enthusiasts trying to re-establish contact with a wayward satellite launched in 1978. Figuratively speaking, it's been off the radar for decades.
"The initial contact was a tone followed by specific commands," project organizer Keith Cowing told NPR's Nell Greenfieldboyce by email. "We learned a lot simply by being able to talk to it and get it to do things.
"May not sound like much but that was a huge unknown," he adds.
Shakespeare calls Richard III "rudely stamp'd," with the king's "hunchbacked" form revealing the twisted soul within. Actors have reveled in playing the monarch as a limping, deformed creature with a withered arm.
But when the bones of the 15th century king were unearthed from beneath a British parking lot in 2012, the skeleton showed no evidence of a hunch. Instead, the vertebrae lay in a curve suggesting that Richard might have had scoliosis.
These days, you can hop on the Internet and buy yourself a consumer-grade brain scanning device for just a few hundred dollars. Technically, they're called brain computer interfaces, or BCIs. As these devices develop, researchers are thinking a few steps ahead — they're worried about how to keep marketers from scanning our brains.
Wildlife biologists have discovered the longest known terrestrial migration in Africa: some 350 miles across southern Africa by huge herds of zebras. Large mammal migration in Africa has generally been hindered by the subdivision and fencing of land. However, this one remains possible because it takes place in a unique, multi-country wildlife corridor.
ROBERT SIEGEL, BYLINE: Now more about the history of cap and trade and how conservatives and environmentalists came together to establish that approach to reducing emissions. To tell us that story, joining us is C. Boyden Gray who assist in the formulation of the policy during the administration of President George H. W. Bush. He was later U.S. ambassador to the European Union. Ambassador Gray, welcome to the program.
