This is the story behind one of the most valuable — and perhaps, most improbable — technologies humanity has ever created. It's a breakthrough called extreme ultraviolet lithography, and it's how the most advanced microchips in the world are made. The kind of chips powering the latest AI models. The kind of chips that the U.S. is desperately trying to keep out of the hands of China. For years, few thought this technology was even possible. It still sounds like science fiction: A laser strong enough to blast holes in a bank vault hits a droplet of molten tin. The droplet explodes into a burst of extreme ultraviolet light. That precious light is funneled onto a wafer of silicon, where it etches circuits as fine as a strand of DNA. Only one company in the world that can make these advanced microchip etching machines: a Dutch firm called ASML. Today on the show, how this breakthrough in advanced chipmaking happened — and how it almost didn't. How the long-shot idea was incubated in U.S. nuclear weapons laboratories and nurtured by U.S. tech giants. And, why a Dutch company now controls it.

Over the past two decades, there's been a sort of tectonic economic shift happening under our feet. More and more companies have switched from selling goods one by one to selling services, available as a subscription. These days everything from razor blades to meal kits to car washes have become subscriptions. But all that convenience has also come with a dark side – some companies have designed their offerings to be as easy as possible to sign up for and also as difficult as possible to cancel. Many consumers are now paying for way more subscriptions than they even know about. On today's show, we discover how we all fell into this subscription trap – who is winning and who is losing in this brave new subscription based world – and what both the government and the free market are doing to try and fix it. This episode was hosted by Alexi Horowitz-Ghazi and Jeff Guo. It was produced by James Sneed.

For our story on this year's Nobel in Economics, check out our daily show, The Indicator! Let's face it. Economics is filled with terms that don't always make sense to the average person. Terms that sometimes mean what you think they mean, but sometimes not at all. Not even close. We surveyed 188 economists. And we asked them: What are the most misunderstood terms in the field of economics? On today's show, their answers! Hear stories about near recessions, a problem with insurance, econ at your local movie theater, and... an economics term that will make undergrads blush. Strap in, and bring your popcorn! This episode was hosted by Amanda Aronczyk and Alexi Horowitz-Ghazi. It was produced by Sam Yellowhorse Kesler with help from Sean Saldana. It was edited by Jess Jiang, engineered by Valentina Rodríguez Sánchez and fact-checked by Sierra Juarez.

You might have seen ads for online banking services that seem to offer a lot of great stuff — accounts you can open in minutes and without a minimum balance or monthly fees. The ads seem to say: "These aren't your parents' boring old banks." But the truth is: Even though they might resemble banks, they aren't. These "bank-like" companies are a type of "fintech" or financial technology company. And this is a story about the potential risks of putting your money into these apps. Banks go through a whole regulatory gauntlet in order to exist. But, in the past several years, there has been a rise in fintechs that skirt regulations. And many of these pose a real threat to even the most savvy of depositors. When a little known tech company filed for bankruptcy a few months ago, thousands of people couldn't access the millions of dollars they saved. On today's show, we meet some of the people affected and learn what the fintech industry reveals about banking regulation. Today's show was hosted by Erika Beras and Sally Helm. It was produced by Sam Yellowhorse Kesler and Sofia Shchukina with help from James Sneed. It was edited by Jess Jiang and fact-checked by Kevin Volkl. It was engineered by Valentina Rodríguez Sánchez with help from James Willetts.

Maybe you got a boring slip of paper in the mail. Maybe you got a spammy-looking email promising you money. Surprise! You're in a class action. If you've done any commerce in the last decade, there's a good chance that someone somewhere was suing on your behalf and you have real money coming your way... if you know what to do. Class action settlements are on the rise. And, on today's show, we're helping decipher the class action from the perspective of the average class member. How do class actions work? Why are these notices sometimes undecipherable? And, what do you stand to gain (or lose) by responding? This episode was hosted by Kenny Malone and Nick Fountain.

Last weekend we were all thrown for a loop when President Joe Biden dropped out of the presidential race and endorsed Kamala Harris for the nomination. Just like everyone else, we are trying to quickly wrap our heads around what it means now that Harris is almost certainly going to be the Democratic nominee for president. We expect to see the Harris campaign come out with some official policy proposals in the coming weeks and months. But for now, all we've got are clues, little breadcrumbs that she has dropped throughout her career that might lead us to a rough idea of what economic policies she might support. Today on the show, we're going to visit three key moments from Harris' political career that might give us an idea of how her economic agenda might look. First, the 2019 presidential primary debates, where she laid out her own economic policies. Next, a vote in her Senate years that shows where she might fall on future trade agreements. And finally, a fight with some of the country's biggest banks from her very first year as Attorney General of California. This episode was hosted by Keith Romer and Nick Fountain. It was produced by Emma Peaslee, edited by Jess Jiang with help from Meg Cramer, and fact checked by Sierra Juarez and Sofia Shchukina. Engineering by Kwesi Lee.

As 20 years of war draw to a close, a divide separates those who served and those who haven't. The "civ-mil divide" can leave veterans alienated and civilians unfamiliar with what it means to serve.

A century ago, people relied on nature to make basic things: toothbrushes were made of silver, combs were made of ivory, and clothes were made of cotton. In a lot of ways, life as we know it today, is possible because of plastic. We can now afford phones, computers and medical devices in part because of one chemist's discovery a century ago. But his descendants have some regrets.

When regulations were imposed to protect Alaska's fisheries it led to a dangerous race to catch fish as fast as possible. A new system to manage sustainable fishing is making the job safer.
