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 Wave producer Hannah Chinn reports.Listen to the whole Tech Camp series. Interested in more military science and/or tech episodes?

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.Interested in more space news?

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 our website for you to guess which is AI-generated and which is human-generated. Check out the full set of stories here.Interested in more science and technology news?

During a total solar eclipse the world around you is very different. The sun gets totally blotted out and suddenly, it feels like night time. The temperature drops. Birds stop singing. These surreal celestial events happen every year or so around the globe – including tomorrow. To get you prepped, we’re talking to eclipse chasers about what makes these few minutes of darkness worthwhile and break down how to view an eclipse. That includes using special specs, so we’re linking the American Astronomical Society’s list of trustworthy eclipse glasses. To nerd out even more, check out NASA’s eclipse website.Interested in more space news?

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 technical report calling for a stop to the science.In this encore episode for our Tech Camp series, host Regina Barber talks to Carl Zimmer, a science reporter at The New York Times, about his reporting on mirror cells — and why creating them could lead to devastating consequences for life on Earth.Check out Carl's full article.Curious about other controversial research?

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.Interested in more science-based biological solutions?
