The Fourth Amendment is the part of the Bill of Rights that prohibits "unreasonable searches and seizures." But — what's unreasonable? That question has fueled a century's worth of court rulings that have dramatically expanded the power of individual police officers in the U.S. Today on the show, how an amendment that was supposed to limit government power has ended up enabling it.To access bonus episodes and listen to Throughline sponsor-free, subscribe to Throughline+ via Apple Podcasts or at plus.npr.org/throughline.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

It's hot. A mother works outside, a baby strapped to her back. The two of them breathe in toxic dust, day after day. And they're just two of thousands, cramped so close together it's hard to move, all facing down the mountain of cobalt stone.Cobalt mining is one of the world's most dangerous jobs. And it's also one of the most essential: cobalt is what powers the batteries in your smartphone, your laptop, the electric car you felt good about buying. More than three-quarters of the world's cobalt supply lies in the Democratic Republic of Congo, whose abundant resources have drawn greed and grifters for centuries. Today on the show: the fight for control of those resources, and for the dignity of the people who produce them.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

Whether it's pesticides in your cereal or the door plug flying off your airplane, consumers today have plenty of reasons to feel like corporations might not have their best interests at heart. At a moment where we're seeing unprecedented product recalls, and when trust in the government is near historic lows, we're going to revisit a time when a generation of people felt empowered to demand accountability from both companies and elected leaders — and got results. Today on the show, the story of the U.S. consumer movement and its controversial leader: the once famous, now infamous Ralph Nader.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

Of all the amendments to the U.S. Constitution, the 14th is a big one. It's shaped all of our lives, whether we realize it or not: Roe v. Wade, Brown v. Board of Education, Bush v. Gore, plus other Supreme Court cases that legalized same-sex marriage, interracial marriage, access to birth control — they've all been built on the back of the 14th. The amendment was ratified after the Civil War, and it's packed full of lofty phrases like due process, equal protection, and liberty. But what do those words really guarantee us?Today on the show: how the 14th Amendment has remade America – and how America has remade the 14th.Clarification: A previous version of this episode did not make clear that the 14th amendment guarantees equal protection and due process to all people in the United States, regardless of citizenship.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

Tipping is a norm in the United States—and it's always been controversial. The practice took off after the Civil War, as employers sought cheap labor from formerly enslaved people: if tips were expected, companies could get away with paying laughably low wages. But the practice was always controversial, and has been vehemently challenged since it first came to the U.S. from Europe. We speak with Nina Martyris, a journalist who's written about the history of tipping in the United States, to find out how tipping—once deemed a "cancer in the breast of democracy"— went from being considered wholly un-American to becoming a deeply American custom.To access bonus episodes and listen to Throughline sponsor-free, subscribe to Throughline+ via Apple Podcasts or at plus.npr.org/throughline.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

Hezbollah is a Lebanese paramilitary organization and political party that's directly supported by the Islamic Republic of Iran. In the wake of the October 7, 2023 Hamas-led attack on Israel, and Israel's invasion of Gaza, Hezbollah and Israel have been exchanging missile fire across the border they share, causing growing fears of a regional conflict with the U.S. and Israel on one side and Iran along with its allies in Hezbollah, Hamas, and the Houthi rebels of Yemen on the other.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

What is school for? Over a hundred years ago, a man named Harold Rugg published a series of textbooks that encouraged students to confront the thorniest parts of U.S. history: to identify problems, and try and solve them. And it was just as controversial as the fights we're seeing today. In this episode: a media mogul, a textbook author, and a battle over what students should – or shouldn't – learn in school.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

What was the worst year to be alive on planet Earth? We make the case for 536 AD, which set off a cascade of catastrophes that is almost too horrible to imagine. A supervolcano. The disappearance of shadows. A failure of bread. Plague rats. Using evidence painstakingly gathered around the world - from Mongolian tree rings to Greenlandic ice cores to Mayan artifacts - we paint a portrait of what scientists and historians think went wrong, and what we think it felt like to be there in real time. (Spoiler: not so hot.) We hear a hymn for the dead from the ancient kingdom of Axum, the closest we can get to the sound of grief from a millennium and a half ago.The horrors of 536 make us wonder about the parallels and perpendiculars with our own time: does it make you feel any better knowing that your suffering is part of a global crisis? Or does it just make things worse?" This week we're sharing a bonus episode from Radiolab: Worst. Year. Ever. Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

In 2011, the world was shaken by the Arab Spring, a wave of "pro-democracy" protests that spread throughout the Middle East and North Africa. The effects of the uprisings reverberated around the world as regimes fell in some countries, and civil war began in others. This week, we revisit the years leading up to the Arab Spring and its lasting impact on three people who lived through it.To access bonus episodes and listen to Throughline sponsor-free, subscribe to Throughline+ via Apple Podcasts or at plus.npr.org/throughline.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

For most of its early history, Israel was dominated by left-leaning, secular politicians. But today, the right is in power. Its politicians represent a movement that uses a religious framework to define Israel and its borders, and that has aggressively resisted a two-state solution with Palestinians. And its government – led by Prime Minister Benjamin Netanyahu — is waging a war in Gaza which, according to the Gaza Health Ministry, has killed over 30,000 people, many of them children. The government launched the war in response to the October 7th, 2023 Hamas-led attack that, according to Israeli authorities, killed over 1,200 Israelis with an additional 250 being taken hostage.This is not the first time that tension has erupted into violence. But the dominance of right-wing thinkers in Israeli politics is pivotal to how the war has unfolded. On today's episode: the story of Israel's rightward shift.Correction: In a previous version of this episode, we said incorrectly that Benjamin Netanyahu was born in 1948. He was born in 1949.To access bonus episodes and listen to Throughline sponsor-free, subscribe to Throughline+ via Apple Podcasts or at plus.npr.org/throughline.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy
