The Pulse

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 ...

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 pept...

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.

• People with ADHD often struggle with task initiation — especially when it comes t...

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 mil...

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.

• The Pulse host Maiken Scott adds some pops of color to her all-black wardrobe with h...

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 p...

We all know we’re supposed to eat healthy — but what exactly does that mean? On this episode, what’s on your plate, why it matters, and how to make sense of conflicting nutrition advice. We talk with paleoanthropologist Daniel Lieberman about what human evolution can teach us about how we should eat, look at a typical teen’s sugar intake, and explore barriers to serving healthy and fresh school lunches.

As summer winds down, some people are celebrating the approach of fall, while others are dreading the shorter, colder days. We know that weather can affect our mood — maybe we're extra irritable when it's hot, or gloomy when it's gray — but it can also influence our overall health. On this episode, a look at how weather affects well-being and health, from its impact on menstrual cycles to chronic conditions like asthma ...

A judge declared a mistrial in the murder trial of Lindsay Clancy after jurors said they were deadlocked over whether she should be held criminally responsible for strangling her three children in January 2023: Cora, 5, Dawson, 3, and Callan, who was just 8 months old. 

The shocking case touched a nerve with millions of people who have been following the trial and asking: How could a mother kill her three young children?

On this episode, a look back at our search for life on Mars. We hear about the Viking mission to Mars — the first to land a craft on the Red Planet — and the controversy over what it discovered, what drove a national obsession with the “Martian civilization” in the early 1900s, and how NASA repairs its rovers from millions of miles away.

• Back in the early 1900s, a strange phenomenon was sweeping the natio...

Journalist Jon Ronson's new book starts with a series of panicked text messages from his son — who had been lured to a massive, gothic-looking castle in Connecticut. A female friend had been invited to a party by a wealthy older man from Tinder. But there was no party. Instead, they were asked to join a reality show that was going to be called "101 Princesses" where women compete for the castle owner’s affection. Ronson...

Sometimes, modern life can feel like an endless cacophony of distractions. We spend our days being inundated with noise and traffic, news and emails, obligations and hectic schedules. Many of us long to escape to nature or the wilderness — someplace simpler, quieter — where we can find peace and reconnect with what's really important. But can we ever truly get away? We tend to think of the wilderness as land that's unto...

Do animals feel love, anger, or empathy? Researchers have long dismissed such ideas as anthropomorphism, arguing that attributing human emotions to animals was unscientific.

But as we learn more about animal sentience, that’s starting to change — and, in the process, we’re learning more than ever about the complex inner lives of animals, including why we may be more alike than we once thought.

What followed was a harrowing journey she was not prepared for. On this episode, what people should consider before quitting. We also explore whether new tools could help doctors better match patients with medications.

• Journalist Erica Gerard was first pres...

In some ways, our imagination is like an all-access pass. It can transport us to a different place, it allows us to picture a beautiful beach, or a lush flower garden. We can envision what our lives may look like in the future or revisit the past. Psychologist Cassandra Vieten argues that using our imagination is not about immersing ourselves in a fantasy world. It’s a powerful tool that affects our physical and mental health...

We tend to think that creativity flourishes in the absence of limits, when we have all of the freedom to innovate and dream big. But what if the opposite is true? What if constraints — from strict rules to tight deadlines — actually make us more creative?

On this episode, we explore how limitations force us to think differently, solve problems in unexpected ways, and allow us to create our best work. We talk with science...

Millions of people in the U.S. have chronic pain that’s unresponsive to medical interventions. But there are new and comprehensive ways of treating pain.

Investigators have long relied on science to help solve crimes, from fingerprint and blood splatter analysis to the psychology of criminal minds. But not every investigative technique rests on solid scientific ground. On this episode, how science is used in criminal investigations, and what happens when these methods aren’t as reliable as we might think.
