Graphite is sort of the one-hit wonder of minerals. And that hit? Pencils. Everyone loves to talk about pencils when it comes to graphite. If graphite were to perform a concert, they'd close out the show with "pencils," and everyone would clap and cheer. But true fans of graphite would be shouting out "batteries!" Because graphite is a key ingredient in another important thing that we all use in our everyday lives: lithium ion batteries. Almost all of the battery-ready graphite in the world comes from one place: China. That's actually true of lots of the materials that go into batteries, like ..read more

Most economic textbooks will tell you that there can be real dangers in running up a big national debt. A major concern is how the debt you add now could slow down economic growth in the future. Economists have not been able to nail down how much debt a country can safely take on. But they have tried. Back in 2010, two economists took a look at 20 countries over the course of decades, and sometimes centuries, and came back with a number. Their analysis suggested that economic growth slowed significantly once national debt passed 90% of annual GDP... and that is when the fight over debt and gr ..read more

For thousands of years, getting light was a huge hassle. You had to make candles from scratch. This is not as romantic as it sounds. You had to get a cow, raise the cow, feed the cow, kill the cow, get the fat out of the cow, cook the fat, dip wicks into the fat. All that--for not very much light. Now, if we want to light a whole room, we just flip a switch. The history of light explains why the world today is the way it is. It explains why we aren't all subsistence farmers, and why we can afford to have artists and massage therapists and plumbers. (And, yes, people who make podcasts about th ..read more

There is a constant arms race between law enforcement and criminals, especially when it comes to technology. For years, law enforcement has been frustrated with encrypted messaging apps, like Signal and Telegram. And law enforcement has been even more frustrated by encrypted phones, specifically designed to thwart authorities from snooping. But in 2018, in a story that seems like it's straight out of a spy novel, the FBI was approached with an offer: Would they like to get into the encrypted cell phone business? What if they could convince criminals to use their phones to plan and document th ..read more

We are living in a kind of golden age for online fraudsters. As the number of apps and services for storing and sending money has exploded – so too have the schemes that bad actors have cooked up to steal that money.

On today's episode, we ride through the streets of San Francisco with a long-time junkman, Jon Rolston. Jon has spent the last two decades clearing out houses and offices of their junk. He's found all sorts of items: a life-time supply of toilet paper, gold rings, $20,000 in cash. Over the years, he's developed a keen eye for what has value and what might sell. He's become a kind of trash savant. As we ride with Jon, he shows us the whole ecosystem of how our reusable trash gets dealt with — from metals (ferrous and non-ferrous) to tires to cardboard. And we see how our junk can sometimes ge ..read more

By one estimate, 40 percent of American workers get laid off at least once in their careers. And when that happens, companies will often say, "It's not personal. It has nothing to do with you or your performance. We're just changing priorities, making a strategic shift." It's like the business version of: "It's not you, it's me." And just like a breakup, it feels terrible. This happened to a man we're calling V, who was working at the same company as his husband when he got laid off. And for V, the experience felt shocking. It left him and his husband with a lot of unresolved questions. On ..read more

Last month, the world narrowly avoided a cyberattack of stunning ambition. The targets were some of the most important computers on the planet. Computers that power the internet. Computers used by banks and airlines and even the military. What these computers had in common was that they all relied on open source software. A strange fact about modern life is that most of the computers responsible for it are running open source software. That is, software mostly written by unpaid, sometimes even anonymous volunteers. Some crucial open source programs are managed by just a single overworked pro ..read more

A man with a clipboard tells her that her home no longer belongs to her. It didn't matter that she'd been paying her mortgage for 17 years, and was current on it. She was a nurse with a good job and had raised her kids here. But this was a foreclosure sale, and she was going to lose her house. Karen had fallen victim to what's called a zombie second mortgage. Homeowners think these loans are long dead. But then the l ..read more
