What’s The Truth About Alcohol’s Benefits And Risks? with Tim Stockwell
We have long heard the claims that a glass of red wine is good for your heart, but it turns out that the research that fueled this wisdom was actually skewed. Some studies made it appear like moderate drinkers were healthier than people who didn't drink at all, leading the public to believe that alcohol was healthier than it is. While drinking alcohol occasionally might not have catastrophic effec
What Happens When We Die? with Sam Parnia
For centuries, death has been seen as a final, inescapable line—a moment when the heart stops and the brain ceases to function.

The Illusion of Moral Decline
This year’s election might have been the most contentious in modern memory. It's not just that politics have changed, but it seems that people have too. You’ve probably heard this phrase: “People aren’t as kind as they used to be”. Maybe you’ve experienced the feeling that people are acting meaner to each other, year after year. But is it true? Are people really less kind than they used to be?With
Can We Predict The Unpredictable? with J. Doyne Farmer
What if we could predict the economy the way we predict the weather? What if governments could run simulations to forecast the effects of new policies—before they happen? And what if the key to all of this lies in the same chaotic systems that explain spinning roulette wheels and rolling dice?J. Doyne Farmer is a University of Oxford professor, complexity scientist, and former physicist who once b
Unlocking The Secrets Of ‘SuperAgers’, with Emily Rogalski
https://haarc.center.uchicago.edu/We used to think aging inevitably led to memory loss, but a small group of people—known as SuperAgers—are defying the odds.

There are two ways to measure how fast the universe is expanding, also known
What Are We Getting Wrong About Young Voters?, with Cathy Cohen
One of the biggest questions of every election is: What’s going on with young voters? There is endless speculation on the news about what young people care about, but very little good research examining their views on the candidates and the issues that matter most to them. The first-of-its-kind GenForward Survey changed that when it was created in 2016 at the University of Chicago.Led by renowned

How Homeownership Shaped Race In America, with Adrienne Brown
Race has played a huge role in the creation of mass homeownership in the United States. Discriminatory housing practices including redlining, exclusionary zoning and whitewashing led to great disparities in home ownership among White and Black homeowners. Despite the passage of the Fair Housing Act in 1968, the damage had been done to communities of color and the rates of Black homeownership. Mass
Fighting Back Against AI Piracy, with Ben Zhao and Heather Zheng
If you’ve spent any time playing with modern AI image generators, it can seem like an almost magical experience; but the truth is these programs are more like a magic trick than magic.

Why We Die—And How We Can Live Longer, with Nobel Laureate Venki Ramakrishnan
They’re perhaps the oldest questions in the science: Why do we die? And could we find a way to live forever? But for decades, anti-aging research was a “backwater” of the scientific community, consider too fanciful and unrealistic. That is until the last few years. Modern advances in biology have taught us a lot about how we age and why we die—could that knowledge help us turn back the clock?In hi

Where Has Alzheimer’s Research Gone Wrong? with Karl Herrup
For more than a century, scientists have been studying Alzheimer’s disease and developing theories about its underlying cause.

Why Shaming Other Countries Often Backfires, with Rochelle Terman
How do you stop a government from continuing to commit human rights abuses? You could take them to an international court of justice, or file a complaint at the UN. But none of those bodies have any enforcement power. Short of going to war, the only option on the table in most international situations is to name and shame.

Do We Really Have Free Will? With Robert Sapolsky
Here’s the question you’re going to be asking for the next 30 minutes: Did I freely choose to listen to this podcast, or did I actually have no choice at all?
