   A survivor's view from inside a tornado

   What’s the dumbest thing Perry Samson says he’s ever done? Getting caught inside a tornado. But when you’re an atmospheric scientist who studies supercell thunderstorms—with a special interest in the ones that cause tornadoes—that sort of thing is a bit of an occupational hazard. Lucky for Perry, he also made a split-second decision while in the tornado that may be the smartest thing he’s ever done. So today on the show: What we can learn from nature at its wildest.

   Could future wars be fought by AI?

   This year, the Department of Defense announced that they’d entered agreements with eight artificial intelligence companies. It follows decades of popular media exploring the idea of artificial intelligence in war – from the computer threatening global thermonuclear conflict in the movie WarGames to the Skynet neural net in Terminator. In 2026, when Anthropic’s Claude and OpenAI’s ChatGPT are just a click away, the concept of AI-supported war is suddenly much closer to reality. So what does it really mean for militaries to use AI? And what are the potential implications if they succeed? Short…

   How to see the year's best meteor shower tonight

   Right now the best shooting star show of the year is happening: the peak of the Perseid meteor shower. People have been viewing this annual event pretty much as long as we’ve been recording history. But what are we really looking at when we gaze up to see these faint streaks of light shoot across the sky? And what can you do to get the best view of them? We dive into those questions on this edition of Spacing Out, which also gets into the latest news about the Sun and the tea behind the SpaceX rocket crashing into the moon.

   Can you spot AI-written stories? Listen and find out

   Can you tell the difference between a human-written short story and an AI-generated one? Most people can’t. In a series of experiments led by a team at Villanova University, researchers found two things: First, most people said they preferred human written stories, but couldn’t tell the difference between AI and human writing; and second, when presented with two similar short stories, one written by a human and one generated by AI, readers tended to prefer the AI-generated piece – especially if they had been told the AI story was written by a human. We excerpted two of the short stories on…

   Mirror cells could threaten life on Earth. Why are we building them?

   For people with two hands, one is usually dominant. On a molecular level, earthly life takes this to the extreme. All of the DNA in living things twists to the right, whereas the protein building blocks favor a kind of left-handed chemistry. The rules of life are based on this chemistry. In recent years, scientists have worked toward a kind of mirror version of life. Currently, the technology doesn't exist to make mirror life at the cellular level — and likely won't for at least a decade. Still, a group of scientists is concerned enough about the possibility that they've published a 299-page…

    More food and money, less disease: Senegal's surprising eco-experiment

    In Senegal, rice farmers are trying to kill three birds with one stone – er, fish. Rice and fish are already a natural combination; they’re even the main ingredients of thieboudienne, the delicious national dish. But could that combination also reduce a debilitating disease, boost food security AND help farmers make more money? A team of researchers are conducting an ambitious experiment to see whether growing rice and fish together can be a win-win-win for Senegal, and NPR’s Jonathan Lambert came along for the ride.
