Celiac disease is thought to affect roughly one percent of the population. The good news: it can be treated by quitting gluten. The bad news: many celiac patients haven't been diagnosed. The weird news: millions of people without celiac disease have quit gluten – which may be a big mistake.

Smart government policies, good industrial relations, and high-end products have helped German manufacturing beat back the threats of globalization.

Public bathrooms are noisy, poorly designed, and often nonexistent. What to do?

He's been U.S. Treasury Secretary, a chief economist for the Obama White House and the World Bank, and president of Harvard. He's one of the most brilliant economists of his generation (and perhaps the most irascible). And he thinks the Trump Administration is wrong on just about everything.

A language invented in the 19th century, and meant to be universal, it never really caught on. So why does a group of Esperantists from around the world gather once a year to celebrate their bond?

We explore votes for English, Indonesian, and … Esperanto! The search for a common language goes back millennia, but so much still gets lost in translation. Will technology finally solve that?

There are 7,000 languages spoken on Earth. What are the costs — and benefits — of our modern-day Tower of Babel?

John Urschel was the only player in the N.F.L. simultaneously getting a math Ph.D. at M.I.T. But after a new study came out linking football to brain damage, he abruptly retired. Here's the inside story — and a look at how we make decisions in the face of risk versus uncertainty.

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.…

Standing in line represents a particularly sloppy — and frustrating — way for supply and demand to meet. Why haven't we found a better way to get what we want? Is it possible that we secretly enjoy waiting in line? And might it even be (gulp) good for us?

The bad news: roughly 70 percent of Americans are financially illiterate. The good news: all the important stuff can fit on one index card. Here's how to become your own financial superhero.

It's hard enough to save for a house, tuition, or retirement. So why are we willing to pay big fees for subpar investment returns? Enter the low-cost index fund. The revolution will not be monetized.

The human foot is an evolutionary masterpiece, far more functional than we give it credit for. So why do we encase it in "a coffin" (as one foot scholar calls it) that stymies so much of its ability — and may create more problems than it solves?

Good intentions are nice, but with so many resources poured into social programs, wouldn't it be even nicer to know what actually works?

Over 40 percent of U.S. births are to unmarried mothers, and the numbers are especially high among the less-educated. Why? One argument is that the decline in good manufacturing jobs led to a decline in "marriageable" men. Surely the fracking boom reversed that trend, right?

How a pain-in-the-neck girl from rural Virginia came to run the most powerful university in the world.

Charles Koch, the mega-billionaire CEO of Koch Industries and half of the infamous political machine, sees himself as a classical liberal. So why do most Democrats hate him so much?

Steve Levitt, Scott Turow and Bridget Gainer are panelists. For the "Freakonomics" co-author, the attorney and novelist, and the Cook County commissioner it's "game on!" as they tackle competition of all kinds: athletic, sexual, geopolitical, and the little-known battle between butter and margarine that landed in the Supreme Court. WBEZ's Trici ...…

A breakthrough in genetic technology has given humans more power than ever to change nature. It could help eliminate hunger and disease; it could also lead to the sort of dystopia we used to only read about in sci-fi novels. So what happens next?

Steve Hilton was the man behind David Cameron's push to remake British politics. Things didn't work out so well there. Now he's trying to launch a new political revolution – from sunny California.

Nearly two percent of America is grassy green. Sure, lawns are beautiful and useful and they smell great. But are the costs — financial, environmental and otherwise — worth the benefits?

A series of academic studies suggest that the wealthy are, to put it bluntly, selfish jerks. It's an easy narrative to swallow — but is it true? A trio of economists set out to test the theory. All it took was a Dutch postal worker's uniform, some envelopes stuffed with cash, and a slight sense of the absurd.…

As CEO of Microsoft, Steve Ballmer was famous for over-the-top enthusiasm. Now he's brought that same passion to the N.B.A. -- and to a pet project called USAFacts, which performs a sort of fiscal colonoscopy on the American government.

On the Internet, people say all kinds of things they'd never say aloud -- about sex and race, about their true wants and fears. Seth Stephens-Davidowitz has spent years parsing the data. His conclusion: our online searches are the reflection of our true selves. In the real world, everybody lies.

A kitchen wizard and a nutrition detective talk about the perfect hamburger, getting the most out of garlic, and why you should use vodka in just about everything.

Some people argue that sugar should be regulated, like alcohol and tobacco, on the grounds that it's addictive and toxic. How much sense does that make?

In pursuit of a more perfect economy, we discuss the future of work; the toxic remnants of colonization; and whether giving everyone a basic income would be genius — or maybe the worst idea ever.

If we could reboot the planet and create new systems and institutions from scratch, would they be any better than what we've blundered our way into through trial and error? This is the first of a series of episodes that we'll release over several months. Today we start with — what else? — economics. You'll hear from Nobel laureate Angus Deaton, ...…

The biggest problem with humanity is humans themselves. Too often, we make choices — what we eat, how we spend our money and time — that undermine our well-being. An all-star team of academic researchers thinks it has the solution: perfecting the science of behavior change. Will it work?

By day, two leaders of Britain's famous Nudge Unit use behavioral tricks to make better government policy. By night, they repurpose those tricks to improve their personal lives. They want to help you do the same.

Hear live journalism wrapped in a game show package and hosted by Stephen J. Dubner. In this episode, Tim Ferriss, Eugene Mirman and Anne Pasternak are panelists. The self-help guru, the comedian and the Brooklyn Museum director talk about brainwaves, sugar, stars and — thanks to fact-checker AJ Jacobs — barf bags.…

Economists preach the gospel of "creative destruction," whereby new industries -- and jobs -- replace the old ones. But has creative destruction become too destructive?

Most of us feel we face more headwinds and obstacles than everyone else — which breeds resentment. We also undervalue the tailwinds that help us — which leaves us ungrateful and unhappy. How can we avoid this trap?

The pizza-and-gaming emporium prides itself on affordability, which means its arcade games are really cheap to play. Does that lead to kids hogging the best games — and parents starting those infamous YouTube brawls?

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.…

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.
