Talk of the Nation

NEAL CONAN, HOST:

Over the past couple of weeks we've seen some important changes on immigration - the president announced a new plan to defer deportation for some young undocumented immigrants, and yesterday the Supreme Court decision on Arizona's controversial immigration law. Much of writer Luis Alberto Urrea's career has focused on life along the U.S.-Mexican border and on the lives of the people who cross it. Now those stories are beginning to change a bit.

The Colorado River touches the lives of Americans coast to coast. The river begins in the Rocky Mountains and flows into Mexico's Sea of Cortez. Along the way, it feeds over a dozen tributaries across the American Southwest.

Many in the West rely on the Colorado for drinking water, and farmers depend on it to irrigate millions of acres of farmland. And if you've ever felt the cool relief of air conditioning in Las Vegas, there's a good chance the electricity was provided by the "mighty Colorado."

When Colum McCann came to the U.S. from Ireland in the early 1980s, he set out on a cross-country bicycle trip to get to know his new country and its stories. He's spent the years since telling those tales through prose. With his project, Story Swap, he's helping diverse communities better understand each other by sharing their own stories.

Wander through one of this country's fine museums of natural history and you'll see animals you'll never see in a zoo: the wooly mammoth, the dodo bird, animals extinct for centuries. But for Stewart Brand extinct doesn't mean gone forever. He's working on a new project, "Revive and Restore," to de-extinct animals we never thought we'd see alive.

The Supreme Court has delivered a split ruling on Arizona's immigration law, striking down several key elements but upholding the "show me your papers" provision. The controversial provision allows local police to check the immigration status of people they stop in the normal course of their duties.

E.O Wilson and Sylvia Earle see the through very different lenses. Wilson started with his eyes to the ground, following ants as they lead him to the study of biodiversity and human nature. Earle dove into the Gulf of Mexico to focus on aquatic plants. That underwater view ultimately led her to study the relationship between degrading seas and life everywhere.

As the climate changes, scientists are documenting measurable shifts in the natural world — from a tremendous loss in Arctic sea ice and an increase in extreme weather like drought, floods and heatwaves, to the migration of plants and animals to new latitudes.

Ever wonder why you worked so hard to avoid the lasagna at dinner only to give in to your craving for not one but two helpings of cake for dessert? Well, new research may hold some answers to this vexing question. A new study in the Journal of Consumer Psychology confirms what we've been - what we've known for some time, and that is each of us has an internal reservoir of self-control. We have a reservoir of self-control that it depletes. Every time we resist a temptation, we use a little bit of it up.

A pair of Canadian skyscrapers have been dubbed the "Marilyn Monroe" towers due to their shapely form. In Abu Dhabi, twin towers are shielded from the sun by computer-controlled shading screens. Architect Antony Wood discusses features of some tall buildings that make them standouts across the world.
