This is TALK OF THE NATION. I'm Neal Conan at the Aspen Institute. News from the Middle East often focuses on problems: violence in Syria; political infighting in Egypt; bombs in the new Iraq; nuclear facilities in Iran; ongoing conflict between Israel and Palestinians.
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.
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.
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.
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.
What if you needed a new toothbrush and all you had to do was hit print? What if doctors could print out transplantable organs and pastry chefs turned to a printer, not a kitchen, for their next creation? Ira Flatow and a panel of guests discuss 3D printing technology, how far it's come and what a 3D-printed-future could look like.
Philadelphia's Mütter Museum has a lot of heart, and other organs too. Items in this collection of medical specimens include a gangrenous hand, a wallet made of human flesh, and a colon the size of a medium suitcase. And that's just the stuff on display, imagine what's in the basement.
This is SCIENCE FRIDAY. I'm Ira Flatow. Last week, China launched its Shenzhou spacecraft into orbit, carrying three taikonauts, one of whom was a woman, China's first female astronaut. A few days later, the spaceship crept up on the Tiangong space lab in orbit and docked with it, making China one of only three countries to have pulled off such a feat after the U.S. and the Soviet Union.
