Peptides are having a moment – but how much do we actually know about them? On this episode, we explore the potential benefits and risks. We investigate the science behind peptides, find out what lagging research and regulation could mean for regular users, and learn about how — and whether – to use peptides in a responsible way.
We talk with Stanford pathology professor Katrin Svensson about what exactly peptides are, what led to their explosion in popularity, and the dangers of unregulated use, both for consumers and for the field of peptide research.
Reporter Bruce Gil dives into the world of consumer peptides, exploring what's driving their growing popularity, the science behind them, and the thorny regulatory landscape. He also talks with regular users about why they started using peptides, and what effects they’ve had on their health.
Many people are interested in peptides, and want access. A growing fleet of clinics and medical providers provide peptide treatments targeting everything from weight loss to muscle growth to cognitive function and mental health. We talk with Evan Miller, the CEO of a chain of clinics called Gameday Men's Health, about how he got into peptides, and what patients should look out for when they’re seeking out peptide treatments.
Peptides are also a hot commodity in skincare products. Dermatologist Elizabeth Houshmand breaks down the different categories of peptides in creams and serums, and how consumers can tell if a product has actually been studied or not.

Most Americans say that spending time with loved ones is one of the most important things in their lives — and yet, amid the hustle and bustle of our day-to-day, relationships often take a backseat to other commitments. We find ourselves canceling date nights to finish work, rescheduling family calls to catch up on chores — maybe even choosing to scroll on our phones over a night out with friends. It can be hard making time for friends and family — and easy to tell ourselves they’ll still be there tomorrow — but there’s a cost to neglecting our personal connections. New research is revealing just how important those ties are, and why nurturing them is an investment not only in our relationships, but in our own health and well-being. On this encore episode, we explore the science of human connection, from why it matters to how we can make it a priority in our lives.
On this episode, we explore ADHD in adults — how to spot it, how to treat it, and how to function with it. We talk with a leading psychologist about what’s behind ADHD’s often frustrating symptoms, hear about what it’s like receiving a diagnosis late in life, and find out why people with ADHD are often very sensitive.
It’s a story that’s unfolding across America, from Texas to Tennessee, Kansas to the Rust Belt — rural hospitals are struggling or closing, leaving residents, towns, and entire regions without access to important healthcare services, from cancer screenings to maternity care. For some people, it can even mean a several-hour drive to the nearest emergency room — and in life-or-death situations, those extra miles can make a big difference.
On this encore episode, we explore the world of color — from how we perceive it, to our efforts to describe and differentiate its many shades. We talk with a lexicographer about efforts to standardize synthetic colors, and how we describe them, and investigate how we know that the colors we see are the same as the ones everyone else sees.
Cereal was born as a health food — but quickly, sweet, crunchy flavor, bright colors, and fun shapes became more important than the nutritional value. That didn’t stop cereal companies from leaning into health claims, though. From Cheerios to Frosted Flakes and Wheaties, brands made bold promises to lower cholesterol, promote weight loss, boost fiber and even help prevent cancer. These healthy messages were also paired with eye-catching designs and beloved mascots. It was all a powerful marketing formula, one that sold a dream to buyers — that indulging in sugary cereal could also be a healthy choice. But, over the years, the healthy veneer has chipped off the cereal box.
