Enough With Baby Talk; Infants Learn From Lemur Screeches, Too

Even infants too young to discern the meaning of words seem better able to learn while listening to the sound of human speech than while listening to nonsense — speech run backward. Little surprise there, perhaps, but a study shows that recordings of lemur calls spark learning, too.

Radiocative Water Leak At Fukushima Worse Than First Thought

The plant that was badly damaged in the 2011 earthquake and tsunami was found to be leaking contaminated water last month.

Drone It To Me, Baby

Drones are for spying, right? Right. But if Jasper van Loenen's idea works, drones will also become private moving vans. Crows won't like this. Trees won't like this. I'm not sure I like this. But you've got to see Jasper's instant-drone deliver a bicycle wheel across campus ...

Don't Call It A Mind-Meld: Human Brains Connect Via Internet

In what they call "direct brain-to-brain communication in humans," researchers at the University of Washington say they've successfully passed signals from one mind to another via the Internet, without using surgical implants.

Wise Old Whooping Cranes Keep Captive-Bred Fledglings On Track

A decade ago, cranes that had never before migrated followed the lead of an ultralight plane to learn the route south. Several generations later, old cranes are teaching young birds to navigate that same route. It's a clue that migration is a combination of nature and nurture, researchers say.

Antibiotic Use On The Farm: Are We Flying Blind?

No one knows exactly how farmers use antibiotics. Many public health experts say the government should collect and publish detailed information because antibiotic-resistant bacteria are an increasingly urgent problem. But many farm groups are opposed.

NASA, Hubble & Outer Space: The Art Of Astronomy (Rebroadcast)

NASA's images and footage are used in everything from TV to movies, and they've inspired visual artists and musicians for decades. We explore how images of space are created and used in everything from scientific study to pop culture.


Another 'Grand Canyon' Discovered Beneath Greenland's Ice

Greenland is covered in an ice layer that's up to 2 miles thick. But below the ice, there's a vast terrain of bedrock. Now scientists have found a mega-canyon there, twice the size of the one in Arizona. The hidden canyon is drawing oohs and aahs from scientists around the world.

Some Rattlesnakes Losing Their Warning Rattle In S. Dakota

There are few things more chilling than the sound of a nearby rattlesnake. That distinctive sound serves as a warning that trouble could be on the way. The only thing worse than hearing a rattlesnake within striking distance — is not hearing it at all. A herpetologist in South Dakota's Black Hills has discovered a growing number of Prairie Rattlesnakes with atrophied tail muscles; he believes it's a genetic issue that multiplies because those snakes that can rattle usually end up being killed. But others think the situation could be an evolutionary development to avoid detection.

A Single Protein May Help Explain Memory Loss In Old Age

Age-related fumbles of memory are often feared as early signs of Alzheimer's dementia, but recent research confirms an important difference. The underlying biology of the two sorts of memory loss aren't the same. And the age-related form may be reversible someday.
