When it comes to sleep, most of us know what to do, we just don’t do it. We know we should put our phones down, create a bedtime routine, and skip the late-day caffeine. Yet one in eight Americans has chronic insomnia, and over half report frequent sleep difficulties. So what’s the disconnect?

In this episode, I sit down with Morgan Adams, a certified sleep coach who spent years battling insomnia herself. After two breast cancer dia...

What can the dying teach us about living well? In this episode, I sit down with Micaelah Morrill, a death doula who helps people and families navigate the final chapter of life with grace and meaning. We met at a Death Café, an open forum where strangers talk honestly about mortality, loss, and what it means to make peace with death.

Our conversation explores what it’s like to sit beside the dying, the lessons we can learn from thei...

At this year’s Cambridge Science Carnival, hosted by the MIT Museum, I set up with one big question: “If science could solve one problem for humanity in the next 50 years, what would you choose—and why?”

Fourteen curious minds, from ages 11 to 64, took the mic to share their answers. From eliminating waste and ensuring clean water, to achieving world peace and even resurrecting dinosaurs, their responses reflect a wide spectrum of h...

In this episode, I’m trying something new with the podcast: more conversation, less script. Inspired by the “Talk of the Table” format from morning shows, I wanted to see what would happen if I stepped out from behind the interview questions and just reacted in real time on timely and topical subjects.

To experiment, I brought back past guest Katie Concannon, who many listeners liked for her humor and authenticity. Armed with topic...

Today, more than ever, we find ourselves in front of a camera—whether it’s a Zoom meeting at work, a video podcast, or content for social media. We live in a visual age, and if you don’t stand out on camera, your message may not reach your audience.

This episode explores how to show up effectively on camera and why it matters. I talk with my friend Anthony Thomas—actor, model, video podcast host, and YouTuber—who shares valuable ti...

In 2022, I joined The Anthony Thomas Podcast to discuss my sci-fi thriller, The Empathy Academy. The novel follows a teenager, Montgomery Hughes, who infiltrates a controversial academy designed to genetically “correct” unethical behavior—only to discover a dark side to the ethics-intervention school.

What started as a guest appearance took an unexpected turn when, halfway through the episode, I flipped the script and began intervie...

Can an AI truly understand us? Does it have thoughts, creativity, or self-awareness? The movie Her was set in 2025—the year we’re living in now. So I decided to interview artificial intelligence itself. In this fascinating 45-minute conversation, I put OpenAI's ChatGPT on the hot seat to explore what AI is actually capable of today, what it fundamentally lacks, and what the future might hold.

Modern psychiatry began with noble intentions: to heal, guide, and support. But has it lost its way?

In this episode of Curiously, I explore this question and much more with Dr. Bruce Levine, a clinical psychologist and outspoken critic of his profession.

Drawing from his latest book, A Profession Without Reason, Levine examines how psychiatry often medicalizes natural traits like curiosity, defiance and rebellion, sometimes to har...

Exercise is good for us. It helps us sleep better, maintain our weight, and lowers the risk of many physical and mental conditions. So, after playing sports in high school and college, I stayed active. I did triathlons and marathons, attended spin classes and yoga classes, and for the last two years, I’ve been working out at Orange Theory, an exercise studio that involves high-intensity work on treadmills, rowing devices and weight...

About 450 million years ago, plants started to colonize the planet. Unable to hide from challenging environmental conditions or run away from insects or herbivores, plants had to get creative to manage diverse ecological pressures. To deal with these challenges, plants exploited their own metabolic systems to produce natural chemicals that helped them survive, from attracting pollinators to deterring herbivores and fighting pathoge...
