AUDIE CORNISH, HOST:

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.

How Language Seems To Shape One's View Of The World

"It's on the left," he says. "No, it's southeast of here," she says.

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.

How Scarcity Trap Affects Our Thinking, Behavior

Originally published on Thu January 2, 2014 7:52 am

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.

A Bet, Five Metals And The Future Of The Planet

This famous bet — between a biologist and an economist — was over population growth. It started three decades ago, but it helped set the tone for environmental debates that are still happening today.

The biologist at the heart of this bet was Paul Ehrlich at Stanford. He wrote a best-selling book in 1968 called The Population Bomb. It was so popular he appeared on The Tonight Show with Johnny Carson.

Why The Cod On Cape Cod Now Comes From Iceland

With local cod so scarce, Chef Toby Hill of Lyric Restaurant in Yarmouth Port, Mass., tries out a dogfish salad — served here with garlic aioli on toast — instead. Dogfish is still plentiful in New England waters, but wholesale fisheries say there's not much demand for it in the U.S.

Good luck finding local cod in Cape Cod, Mass.

The fish once sustained New England's fishing industry, but in recent years, regulators have imposed severe catch limits on cod, and the fish remain scarce.

"I've never seen cod fishing this bad," says Greg Walinsky, who has been fishing on Cape Cod for more than 30 years. "It looks to me like it's over. And I can't catch any codfish."

It's so bad, many fishermen say, that for the first time, they cannot catch enough cod to even reach shrinking government quotas.

How Mass-Produced Meat Turned Phosphorus Into Pollution

A dead carp floats in water near the shore at Big Creek State Park on Sept. 10 in Polk City, Iowa. Like many agricultural states, Iowa is working with the EPA to enforce clean-water regulations amid degradation from manure spills and farm-field runoff.

It's a quandary of food production: The same drive for efficiency that lowers the cost of eating also can damage our soil and water.

Take the case of one simple, essential chemical element: phosphorus.

More Than 300 Sharks In Australia Are Now On Twitter

A shark warning is displayed near Gracetown, Western Australia, in November. An Australian man was killed by a shark near the area that month, sparking a catch-and-kill order.

Sharks in Western Australia are now tweeting out where they are — in a way.

Government researchers have tagged 338 sharks with acoustic transmitters that monitor where the animals are. When a tagged shark is about half a mile away from a beach, it triggers a computer alert, which tweets out a message on the Surf Life Saving Western Australia Twitter feed. The tweet notes the shark's size, breed and approximate location.

Researchers Create New 'Memory' Metals That Could Improve Safety

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 Race Against Time In Warming Arctic Coasts

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.
