How flying got so bad (or did it?)

We often hear that air travel is worse than it's ever been. Gone are the days when airplanes touted piano bars and meat carving stations — or even free meals. Instead we're crammed into tiny seats and fighting for overhead space.

The two companies driving the modern economy

At the core of most of the electronics we use today are some very tiny, very powerful chips. Semiconductor chips. And they are mighty: they help power our phones, laptops, and cars. They enable advances in healthcare, military systems, transportation, and clean energy. And they're also critical for artificial intelligence, providing the hardware needed to train complex machine learning.

Do immigrants really take jobs and lower wages?

We wade into the heated debate over immigrants' impact on the labor market. When the number of workers in a city increases, does that take away jobs from the people who already live and work there? Does a surge of immigration hurt their wages?

The Vapes of Wrath

The Vapes of Wrath

When the vape brand Juul first hit the market back in 2015, e-cigarettes were in a kind of regulatory limbo. At the time, the rules that governed tobacco cigarettes did not explicitly apply to e-cigarettes. Then Juul blew up, fueled a public health crisis over teen vaping, and inspired a regulatory crackdown. But when the government finally stepped in to solve the problem of youth vaping, it may have actually made things worse.

Why is everyone talking about Musk's money?

We've lived amongst Elon Musk headlines for so long now that it's easy to forget just how much he sounds like a sci-fi character. He runs a space company and wants to colonize mars. He also runs a company that just implanted a computer chip into a human brain. And he believes there's a pretty high probability everything is a simulation and we are living inside of it.

What's with all the tiny soda cans? And other grocery store mysteries, solved.

There's a behind the scenes industry that helps big brands decide questions like: How big should a bag of chips be? What's the right size for a bottle of shampoo? And yes, also: When should a company do a little shrinkflation?

Bringing a tariff to a graphite fight

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.

How much national debt is too much?

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.

The history of light (classic)

The history of light (classic)

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.
