Beginning in the 1950s, American and Soviet scientists engaged in a dangerous race to build and detonate the world’s largest bomb. The results exceeded all expectations about how big a bomb could be built. The United States led the way, but then left the field clear for the Soviet Union to break all records. The bomb-makers on both sides were flying blind as they pushed the technology far into unknown territory. Trace this chilling story, fully told for the first time.
The loneliest animals are the most endangered species on the planet. Collected and protected by dedicated scientists, these animals represent the end of the line for their species. In many cases, intensive captive breeding programs have been launched with the aim of sustaining these animals and the hope of returning them to the wild. Viewers are taken into high-security, high-tech labs where scientists attempt to breed new generations and into the field to discover what forces have led to the demise of entire species.
Robots and algorithms can now build cars, write articles, and translate texts — all work that once required a human. So what will we humans do for work? Andrew McAfee looks at recent labor data to say: We ain't seen nothing yet.

Last year, a federal program called the Earned Income Tax Credit took about $60 billion from wealthier Americans and gave it to the working poor. And here's the surprising thing: This redistribution of wealth has been embraced by every president from Ronald Reagan to Barack Obama.
"This program worked," says Richard Burkhauser, an economist at Cornell University and the American Enterprise Institute. "And there's not a hell of a lot of these programs where you can see the tremendous change in the behavior of people in exactly the way that all of us hoped it would happen."
Sorry to disappoint, but science writer Carl Zimmer says we're not going to bring back dinosaurs. But, he says, "science has developed to the point where we can actually talk seriously about possibly bringing back more recently extinct species."
It's called "de-extinction" — and it's Zimmer's cover story for National Geographic's April issue.
