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. These individuals, all over 80, have the memory performance of someone in the 50s. The question is: how? One of the leading experts studying SuperAgers is University of Chicago neurologist Emi…

On Big Brains, we get to speak to a lot of groundbreaking scholars and experts, but some conversations we walk away knowing we’ve just heard from someone who is really changing the world. We certainly felt that way years ago after talking to University of Chicago scholar James Robinson, and it turns out…the Nobel Prize committee agreed in 2024 when…

How old is the universe—and how fast is it expanding? These are part of one of the biggest—and most contested—questions in science, and the answers could change our understanding of physics. In this episode, we talk with renowned UChicago astronomer Wendy Freedman, who’s spent decades trying to solve these very questions. There are two ways to meas…

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 …

More and more women in the United States are saying no to motherhood. Alarmingly, in 2023, the U.S. fertility rate reached the lowest number on record. But the idea of non-motherhood is actually not a new phenomenon, nor did it come out of the modern feminist movement. For centuries, women have made choices about limiting births and whether or not …

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 o…

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. Without the human-generated art of hundreds of thousands of people, these programs wouldn’t work. But those artists are not getting compensated, in fact many of them…

In the near future, birth defects, traumatic injuries, limb loss and perhaps even cancer could be cured through bioelectricity—electrical signals that communicate to our cells how to rebuild themselves. This innovative idea has been tested on flatworms and frogs by biologist Michael Levin, whose research investigates how bioelectricity provides the…

Can you heal faster just by tricking your brain? Could you lose weight with only a change of mindset? Could you think yourself into being younger? If you think the answer to all these questions is no, you haven’t read the research from renowned Harvard University psychologist Ellen Langer. Our podcast is taking a quick summer break, but we wanted t…

We've all been stuck at some point in our lives — whether we've been stuck at a job and wanting to make a career change, stuck in a location and wanting to move somewhere new, or stuck in relationships or friendships. But the method to getting “unstuck” and achieving a breakthrough might be easier than you think. Using research-backed tools, New Yo…

There is a science to what we remember and what we don't. For instance, why do we remember certain pieces of artwork, some brands’ logos, or even people's faces? University of Chicago psychologist Wilma Bainbridge has been studying what makes things memorable for over a decade. Through her research, she has found that there is a common thread about…

If aliens landed on Earth tomorrow, how would we talk with them? Well, we already have a kind of creature on this planet we could attempt to talk to first, and in the last few years a team of renowned scientists have been exploring the ocean studying sperm whales to get that conversation going. David Gruber is a professor of biology and environment…

We all know that extreme weather events like hurricanes are getting worse due to climate change, but what scientists would really like to know is: By how much worse exactly? This year a team of researchers argued that hurricanes have become so much more extreme due to climate change that we need to add a new category 6 to the Saffir-Simpson scale, …

We've all heard the phrase "Manifest Your Destiny" when it comes to wanting that new promotion, figuring out a new career path or just trying to achieve that long-term goal. It turns out that the act of manifestation is not merely pseudoscience—it actually has a body of research in neuroscience to back it up. Dr. James Doty has been exploring this …

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—coul…

Every dog owner has faced the hard realization that their dog won’t live as long as they do, but we’ve all probably wondered: Why do some dogs live longer than others? It turns out that several factors are at play, according to the largest research study of dogs, known as The Dog Aging Project. Prof. Daniel Promislow of the University of Washington…

For more than a century, scientists have been studying Alzheimer’s disease and developing theories about its underlying cause. The leading theory for decades has been that abnormal amyloid plaques in the brains of those who suffer from the disease are the central cause. But, according one renowned Alzheimer’s researcher, this myopic focus is not on…

Mosquito-borne diseases are one of the greatest global health threats, infecting around 700 million people every year with Zika virus, dengue fever, malaria and yellow fever — which can all be deadly if left untreated. Unfortunately, the mosquito population is not slowing down, and factors like climate change and increased global travel are broaden…

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. But is that strategy effe…

The Supreme Court’s decision on whether Colorado can take former President Donald Trump off the ballot in the 2024 election may be one of the most consequential in its history. The case will turn on the court’s interpretation of Amendment 14, Section 3 of the Constitution, which bars any previous elected official from holding office if they partici…

Language shapes our world. But when we speak, there is actually a secret conversation happening beyond our words. It’s happening not with our mouths—but with our hands. Prof. Susan Goldin-Meadow is a distinguished scholar of psychology at the University of Chicago. Her research into deaf children who were never taught sign language led her to study…

The United States is facing a real mental health crisis. In the last few years, one possible treatment has gotten a lot of press: psychedelic drugs. But what is actually happening in a person’s brain when they take a psychedelic? Could understanding the biology and the chemistry allow us to make better and safer versions of these drugs—and maybe ev…

The Big Brains team is taking some time off during the holidays but for all those travelers out there heading home, we wanted to make sure you still had your favorite podcast in your feed. So, we’re resharing one of our most popular episodes ever. It’s about the science of happiness. What is the key to living a happy and fulfilling life? The answer…

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? Most of us probably believe we have free will. We feel like we make decisions, and that each of us is responsible for the consequences of our actions. But what if that’s all just an illusion?…

Climate change can feel like an impossible crisis these days. Every week there is some new report about the irreversible damage we’re doing to our planet and the havoc it will bring to people’s lives. We all know cutting emissions is the solution, yet governments and companies seem no closer to meeting the goals that scientists say we must hit. It …
