The serial entrepreneur Miki Agrawal loves to talk about the bodily functions that make most people flinch. That's why she's building a business around the three P's: periods, pee, and poop.

In their chase for a global audience, American movie studios spend billions to make their films look amazing. But almost none of those dollars stay in America. What would it take to bring those jobs back -- and would it be worth it?

What happens when a public-health researcher deep in coal country argues that mountaintop mining endangers the entire community? Hint: it doesn't go very well.

The psychologist Angela Duckworth argues that a person's level of stick-to-itiveness is directly related to their level of success. No big surprise there. But grit, she says, isn't something you're born with — it can be learned. Here's how.

We assembled a panel of smart dudes -- a two-time Super Bowl champ; a couple of NFL linemen, including one who's getting a math Ph.D. at MIT; and our resident economist -- to tell you what to watch for, whether you're a football fanatic or a total newbie.

For years, economists promised that global free trade would be mostly win-win. Now they admit the pace of change has been "traumatic." This has already led to a political insurrection -- so what's next?

Just a few decades ago, more than 90 percent of 30-year-olds earned more than their parents had earned at the same age. Now it's only about 50 percent. What happened -- and what can be done about it?

The Daily Show host grew up as a poor, mixed-race South African kid going to three churches every Sunday. So he has a sui generis view of America — especially on race, politics, and religion — and he's not afraid to speak his mind.

Starting in the late 1960s, the Israeli psychologists Amos Tversky and Danny Kahneman began to redefine how the human mind actually works. Michael Lewis's new book The Undoing Project explains how the movement they started -- now known as behavioral economics -- has had such a profound effect on academia, governments, and society at large.

What if the thing we call "talent" is grotesquely overrated? And what if deliberate practice is the secret to excellence? Those are the claims of the research psychologist Anders Ericsson, who has been studying the science of expertise for decades. He tells us everything he's learned.

In this busy time of year, we could all use some tips on how to get more done in less time. First, however, a warning: there's a big difference between being busy and being productive.

By some estimates, medical error is the third-leading cause of death in the U.S. How can that be? And what's to be done? Our third and final episode in this series offers some encouraging answers.

How do so many ineffective and even dangerous drugs make it to market? One reason is that clinical trials are often run on "dream patients" who aren't representative of a larger population. On the other hand, sometimes the only thing worse than being excluded from a drug trial is being included.

We tend to think of medicine as a science, but for most of human history it has been scientific-ish at best. In the first episode of a three-part series, we look at the grotesque mistakes produced by centuries of trial-and-error, and ask whether the new era of evidence-based medicine is the solution.

The restaurant business model is warped: kitchen wages are too low to hire cooks, while diners are put in charge of paying the waitstaff. So what happens if you eliminate tipping, raise menu prices, and redistribute the wealth? New York restaurant maverick Danny Meyer is about to find out.

Some of our most important decisions are shaped by something as random as the order in which we make them. The gambler's fallacy, as it's known, affects loan officers, federal judges -- and probably you too. How to avoid it? The first step is to admit just how fallible we all are.

"Tell Me Something I Don't Know" is a live game show hosted by Stephen J. Dubner of "Freakonomics Radio." He has always had a mission: to tell you the things you thought you knew but didn't, and things you never thought you wanted to know, but do. Now, with "TMSIDK," he has a new way of doing just that. This new show is still journalism, still factual -- but disguised in the most entertaining, unexpected, and occasionally ridiculous conversation you're likely to hear.Audience contestants come on stage and try to wow a panel of experts with a fascinating fact, a historical wrinkle, a new line of research -- anything, really, as long as it's interesting, useful and true (or at least true-ish). The panel -- an ever-changing mix of comedians, brainiacs, and other high achievers -- poke and prod the contestants, and ultimately choose a winner. And there's a real-time, human fact-checker on hand to filter out the bull.This debut episode features Barnard College president Debora Spar, N

Societies where people trust one another are healthier and wealthier. In the U.S. (and the U.K. and elsewhere), social trust has been falling for decades -- in part because our populations are more diverse. What can we do to fix it?

The U.S. president is often called the "leader of free world." But if you ask an economist or a Constitutional scholar how much the occupant of the Oval Office matters, they won't say much. We look at what the data have to say about measuring leadership, and its impact on the economy and the country.

A tiny behavioral-sciences startup is trying to improve the way federal agencies do their work. Considering the size (and habits) of most federal agencies, this isn't so simple. But after a series of early victories -- and a helpful executive order from President Obama -- they are well on their way.
