A quarter of young adults are turning to AI chatbots like ChatGPT for mental health advice, highlighting a massive shift in how people seek support. Dr. Ateev Mehrotra discusses his research and the urgent need to balance AI's capacity for providing accessible, cost-effective care with its potential to unwittingly cause harm.

In a world teeming with health data—from smart watch accelerometry to millions of hospital system electronic records—how do researchers find out which medical treatments truly work? Biostatistician Rebecca Hubbard discusses the messiness of real-world data, the limits of randomized control trials and how both of these powerful—but imperfect—methods are essential for building trustworthy evidence in public health.

Measles has been declared eliminated in the U.S. for 25 years, but a surge in cases is threatening that status. Jennifer Nuzzo, director of the Pandemic Center at Brown University, joined Humans in Public Health to break down the outbreak, the chaotic federal response and how her team's tracker is stepping in to provide reliable, life-saving data.

We all understand the power a song can have to recall vivid memories, seemingly sending us back in time. Professor Ellen McCreedy is a musician whose gerontology research harnesses music’s power to recall memories. She’s testing an intervention that brings personalized music playlists to nursing homes in order to help ease dementia symptoms for patients, without using medication. Driven to give dementia sufferers—and their caregivers—moments of having themselves back again, McCreedy joined Humans in Public Health to discuss her work, its challenges and the grandmother who originally inspired her.

Since the 1980s, the U.S. has experimented with various forms of managed health care. But none of them has managed to control costs or improve health outcomes, argues Senior Fellow Hayden Rooke-Ley.

What happens when private equity firms buy hospitals and doctor’s offices? In this episode of Humans in Public Health, host Megan Hall sits down with health care economist Yashaswini Singh to unpack how private equity is reshaping the American health care system—often behind the scenes. From rising costs to shifting priorities in patient care, Singh explains why the recent collapse of Steward Health Care is just the tip of the iceberg. Whether you’ve heard the term “private equity” or not, this conversation will change the way you think about your next doctor’s visit.

They’re not just in your nail polish. Per- and polyfluoroalkyl chemicals are everywhere—in our homes, clothing, the personal care products we use, and in our bodies. Postdoctoral researcher Amber Hall explains the dangers PFAS pose, especially to developing humans, and helps us learn how to avoid them. The burden of protecting our children’s health from toxic chemicals, she argues in the latest episode of Humans in Public Health, shouldn’t be borne by individuals. Regulation, Hall says, is needed to push through product-level change and protect the public’s health.
