The Pulse – Details, episodes & analysis

When someone wrongs us, getting revenge can feel like the only right move — the only way for us to balance the scales, to set the world right again. But the consequences can be disastrous, especially when payback becomes an all-consuming obsession. 

On this episode, we talk with lawyer-turned-researcher James Kimmel about his new book, "The Science of Revenge: Understanding the World's Deadliest Addiction — and How to Overcome It." We discuss the evolutionary roots of revenge, the neuroscience behind why it feels so good, and how Kimmel eventually traded vengeance for forgiveness. We also find out what caused a murder of crows to target an unsuspecting woman, and what was behind their years-long grudge.

Creativity plays a role in every facet of our lives, from childhood education, to everyday problem-solving, to the artistic works we enjoy and the innovations shaping our future. We explore what human creativity is, how it works, and some of the unexpected ways it’s remaking our world.

On this episode, we mark the 20th anniversary of YouTube with an exploration of how the video-streaming platform has transformed everything from global pop culture, to social movements, to how we seek out and consume information. We hear about new research on how short-form videos affect our brains, how algorithms dictate culture, and what makes YouTube so helpful — and addictive.

Over the past few years, remote working has transformed millions of people's lives — giving them more time for family, more control over their schedules, and a better work-life balance. But now, a growing number of companies — including tech giants like Google and Meta — are making their employees return to the office, citing concerns about productivity, innovation, creativity, and employee engagement. But how does working in the office measure up when compared to working remotely? On this episode, we explore the future of remote work, and hear about the latest research on which settings and models are best. When does it pay off to bring workers back, and when is working remotely more fruitful? We hear stories about how digital nomads are reshaping what work looks like — and the places they live; how working from home affects productivity; and how workplace psychologists say office design could lure employees back to the workplace.

Science is all about observing the world. But how do you study something you can't see, smell, or hear — like the tiniest particles all around us? How do you test a new energy source when it doesn't really exist yet? These are the challenges that the world of physics often faces. You can come up with theories, using modeling and calculations, and devise some kind of experiment on paper to investigate things. But then you have to translate those ideas into tangible, real-world experiments, which is often incredibly challenging. On this episode, we peek behind the curtain of multimillion-dollar physics experiments that are changing the way we understand our world — and hear about some of the big challenges they face. We dig into the origins of the James Webb Space Telescope, talk with xkcd cartoonist Randall Munroe about some of his more outlandish — and complicated — physics calculations, and hear from accelerator physicist Suzie Sheehy about the physics experiments that changed the world.

Whether you're a student or a doctor, a plumber or a truck driver, a university lecturer or a radio reporter, artificial intelligence is changing the way we work. For some workers, A.I. is taking over tedious and time-consuming tasks, freeing them up to focus and get more done. For others, it's led to questions about what A.I. means for the future of work — or whether, in a few years, they will have jobs at all. What are the limits of A.I.'s abilities? How can it help us do our jobs better rather than simply replacing us? What checks and balances do we need to control its development? And are there any jobs that will not be affected? On this episode, we explore how A.I. is transforming the way we work — for good and for bad. We hear stories about the future of robot plumbers, the push to integrate A.I. into medical education, how physicians are responding to its increasing presence in medicine, and the dystopian threat of neurotechnology.

It seems like every day, new skin care products hit the market: lotions, serums, collagen boosters, light therapy, at-home lasers — potions and procedures designed to coax our skin into peeling and healing, plumping and renewing. Their promise: wrinkle-free faces, poreless, dewy skin, and an eternally youthful glow.

But there's no one magic bullet to flawless skin. And what is this chase really about?

On this episode, we get into the science of skin care, looking at what works, what doesn't, and what dermatologists have to say about the latest frontiers in our quest for eternal youth. We hear stories about a new treatment that uses stem cells to rejuvenate skin, some shady aspects of the Botox business, and why K-beauty has taken global skin care by storm.

If you've tried to book a doctor's appointment lately, chances are, it's been challenging. Many practices are not taking new patients, or open slots are weeks or months away. For some patients, it has meant gritting their teeth through pain and anxiety.

For others — like people living in rural areas or trying to see in-demand specialists like psychiatrists or neurologists — it can feel almost impossible to get an appointment at all, posing real threats to their health. Medical organizations warn that we're experiencing a physician shortage — and that things will only get worse.

On this episode, we look at this, and other, shortages plaguing the world of medicine, from medications to donated blood. We investigate what's causing this scarcity, and some potential solutions. We'll hear stories about the surprising origin of the physician shortage, and why we still have unemployed MDs sitting at home; what's behind the recent shortages of several high-profile medications; and how researchers are trying to address the chronic shortage of donated blood.

For centuries, writers and philosophers have imagined what a perfect world might look like — if only we had a chance to start over, build it all from scratch. The term "utopia" comes from ancient Greek. It literally means "no place," but it's also a pun on "eutopia," meaning "good place." In other words, it's a good place that doesn't exist. But that hasn't stopped a never-ending stream of dreamers and seekers — from political and economic theorists, to dictators, hippies, and religious zealots — from trying to create utopias of their own.

So, what is it that makes the idea so seductive? Who is attracted to a more perfect world? And what happens when it all goes wrong? On this episode, we explore modern attempts at real-life utopias. We'll hear about an AI researcher's doomed mission to establish a post-apocalyptic community in the Scottish Highlands, what it's like growing up in a utopian community, and the dark side of efforts to build sustainable smart cities around the world.

When you're at the doctor's office or a hospital, it's easy to get frustrated. Why is this taking so long? Why do the nurses look so tired? Why does my doctor seem distracted? Who's making sure my diagnosis is right?

There are people, stories, and entire worlds that could provide answers to these questions — but as patients, we don't get to see them. So, on this episode, we'll take you behind the waiting room doors, to talk about some of the big issues that affect the health care workforce. We'll hear stories about the decades-long fight over residents' work hours, the history of travel nursing, and what two long-time ER nurses have to say about burnout. We'll also meet some of the crucial, but little-known, professionals who work behind the scenes in medicine.
