From NPR News, this is ALL THINGS CONSIDERED. I'm Audie Cornish. Toyota, Honda, Hyundai recently announced that they're planning to build hydrogen-powered cars in the next few years. These cars could rival all electric and plug-ins as cleaner alternatives to gasoline-powered cars. NPR's Richard Harris took a drive in a hydrogen car to learn about the advantages and drawbacks of the technology.

Lera Boroditsky once did a simple experiment: She asked people to close their eyes and point southeast. A room of distinguished professors in the U.S. pointed in almost every possible direction, whereas 5-year-old Australian aboriginal girls always got it right.

There is a widespread narrative in higher education that goes something like this: Colleges and universities have always accepted the best and brightest students; then, due to pressure from outside forces (some of them named "John F. Kennedy"), diversity was thrust upon the academy. In turn, schools meted out race-based scholarships, relaxed standards for certain students in order to fulfill quotas and — poof! — diversity.
A Harvard economist finds there are psychological connections between the bad financial planning of many poor people and the poor time management of busy professionals. In both cases, he finds the experience of scarcity causes biases in the mind that exacerbate problems.
Some metal alloys will "remember" a shape when you heat them to the same temperature they were originally shaped at. So a straight wire made from one of these "shape memory alloys" might change back into a spring when heated, or vice versa. But the alloys that exist today change shape at low temperatures. Materials scientists at Sandia National Laboratory have developed new alloys that don't change shape until they reach hundreds of degrees, opening the door to thousands of new applications.
Archeologists who study the people who lived in the Arctic thousands of years ago are in a race against time. Coastal settlements are being washed away by erosion, storm surges and other climate changes related to global warming. Clues to the past that were frozen intact in permafrost for thousands of years are melting and being destroyed by the elements. Archeologists are looking to climate scientists to predict where the erosion will be the fastest so they can pinpoint their research on the places that will disappear the soonest.
It was a rainy night in October when my nephew Lewis passed the Frankenstein statue standing in front of a toy store. The 2 1/2-year-old boy didn't see the monster at first, and when he turned around, he was only inches from Frankenstein's green face, bloodshot eyes and stitched-up skin.
The 4-foot-tall monster terrified my nephew so much that he ran deep into the toy store. And on the way back out, he simply couldn't face the statue. He jumped into his mother's arms and had to bury his head in her shoulder.
