The U.S. has fallen into polarized, partisan, political bickering. Online, liberals and conservatives seem to despise each other. But nobody seems to stop to ask: How did we get our liberal and conservative views in the first place? We formed our opinions by carefully weighing the issues and thoughtfully choosing a stance, right? Well, no; turns out over half of our political leanings are determined, incredibly, by our genes. In this episode: How we figured that out, and what it means for our future. Learn more about your ad choices. Visit megaphone.fm/adchoices

Every month, over a billion people open their phones and fire up Google Maps. Its original function—offering driving directions, with real-time traffic tracking—was disruptive enough in 2008, when most people had to pay $10 a month for traffic data. But since that time, it’s become a global business directory, a transit timetable, crowdedness monitor, a Street View miracle—and now, in its newest release, an augmented-reality viewer of the cityscape around you. The question is: How is Google doing it, and why is it free? Meet the man who runs Google’s entire Geo division. Learn more about your ad choices. Visit megaphone.fm/adchoices

Genealogy has been around a while. So has DNA evidence. But what if you combined the two? What if you could use DNA from a crime scene, compare the unknown killer’s genetics with public databases of other people’s DNA, figure out who his relatives are, and thereby determine his identity? That’s the system that CeCe Moore invented five years ago. So far, she’s cracked over 270 cold cases using this method—and brought closure to hundreds of grieving families.

65 million years ago an asteroid struck the earth. In the ensuing planetary darkness, the dinosaurs went extinct. But the dinosaurs didn’t have a space program! Now we can spot incoming asteroids with steadily improving confidence. If we see one on a collision course with the Earth, we know from the movies that the solution is to nuke it...Right? Actually, NASA has a better idea. If you can just nudge an asteroid slightly off its current path, maybe 25 or 50 years before it hits us, it won’t hit the earth. It will sail harmlessly past us. In 2022, NASA put that idea to the test. It sent a tiny spacecraft 7 million miles into space, for the express purpose of crashing into a known asteroid—to see if we could bump it into a different path. We quickly found out. This is the story of the DART (Double Asteroid Redirection Test) mission. Hear from Dr. Richard Binzel, MIT professor. Dr. Elena Adams, lead engineer for NASA’s DART mission, and Dr. Lori Glaze, director of NASA’s planetary science division. Learn more about your ad choices. Visit megaphone.fm/adchoices

In 1915, British explorer Sir Ernest Shackleton’s historic expedition to Antarctica stalled when floating ice trapped, crushed, and finally sank his ship, Endurance. Shackleton’s men survived 21 months on the ice, alone and freezing, and became one of the most incredible adventure stories ever recorded. The ship itself, Endurance, was not seen again for 106 years. Every attempt to find it wound up thwarted by exactly the same enemy: crushing sheets of pack ice. Finally, in 2022, an international team of explorers and scientists found the wreck—and it’s in absolutely pristine condition. This is the story of how they found it.
