The Pulse

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.
On this episode, we explore what researchers have discovered about what’s really going on inside other species’ heads. We talk with a primatologist about why she believes baboons and other animals possess a theory of mind; investigate whether crabs, lobsters, and shrimp are capable of experiencing pain; and hear about one beagle’s journey from lab subject to pet.

Host Maiken Scott and reporter Alan Yu visit  the Chamounix Equestrian Center in Philadelphia to test an app that claims to detect pain in horses.

When primatologist Christine Webb was in college, she was taught that it was "unscientific" to investigate animal emotions — but that attitude has started to change. We talk with Webb about what’s causing that shift, what she learned from her mentor, the famed primatologist Frans de Waal, and the challenges involved with stepping outside our human biases to understand the inner lives of animals. Webb is an assistant professor in the Department of Environmental Studies at New York University, and her new book is “The Arrogant Ape: The Myth of Human Exceptionalism and Why it Matters.”

Reporter Sophia Schmidt pays a visit to the Elmwood Park Zoo in Norristown, Pennsylvania to meet an unlikely pair of besties: Hunter, the red-tailed hawk, and Stan, the turkey vulture. We hear about why Hunter and Stan’s relationship is so rare, how they became friends (and, sometimes, more than friends), and what biological factors could be driving their behavior.

It’s easy enough to believe that animals like cats and dogs have feelings — but what about less cuddly creatures, like crabs, lobsters, and shrimp? Pulse reporter Liz Tung talks with researchers who’ve been investigating the question of sentience in decapod crustaceans, and whether or not they’re capable of feeling pain.

We talk with journalist Melanie Kaplan about her investigation into the world of animal research, spurred by her adoption of Hammy — a beagle who spent the first four years of his life in a lab. Her book is, “Lab Dog: A Beagle and His Human Investigate the Surprising World of Animal Research.”

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 encore episode, we talk with lawyer-turned-researcher James Kimmel about his 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.

Artificial Intelligence is already guiding surgeons in operating rooms; it’s used to read image scans or take notes during your doctor’s visit. And the pace of AI integration is only getting faster. So what will health care look like in the next 10 to 20 years? Will we consult with an AI-powered doctor before we see our primary care physician or a specialist? Will it give more patients access to cutting-edge care? On this episode; a conversation with physician Robert Wachter on the future of medicine. He’s the chair of the Department of Medicine at the University of California, San Francisco and author of “A Giant Leap: How AI Is Transforming Healthcare and What That Means for Our Future."

For those deep in the dating trenches, love and attraction can feel like uncrackable riddles. How do I make myself attractive to others? How do you know if someone’s into you? What should I look for in a partner — and how do I know if I’ve found “the one”?
On this episode, we train a scientific lens on the mysteries of love. We talk with psychologist Paul Eastwick about the latest research on attraction, relationships, and finding love; learn about how dating apps are transforming the courting process; and hear about two couples who found love in unexpected places.

Researcher Paul Eastwick discusses what fuels romantic attraction, why dating apps aren’t necessarily the best way to gauge compatibility, and what makes for a good and healthy relationship. Eastwick is the principal investigator for the attraction and relationships research laboratory at the University of California, Davis. His new book is “Bonded by Evolution: The New Science of Love and Connection.”

By most measures, Danielle and Kevin Robinson’s longtime marriage is what the kids would call “relationship goals” — they laugh constantly, share the same interests, and get along like a house on fire. But, in the beginning, not everyone thought they were a match — including Kevin. Pulse reporter Liz Tung tells the story of how they got together, and what their romance shows about compatibility, and different kinds of attraction.

When it comes to love stories, Celine Broeckaert and Frank Verstraete have a pretty unique one — they fell in love while writing a book about quantum physics. We hear the story of how the unlikely pair — Broeckaert a playwright and filmmaker, and  Verstraete a quantum physicist — met, what it was about working on the book that bonded them together, and how the right partner can bring a new magic to the familiar. Their book is “Why Nobody Understands Quantum Physics: The Story of the Science That Shapes Our World.”

When it comes to serious health issues like obesity, heart disease, and cancer, Black Americans have higher rates and worse outcomes than most other groups in the U.S. It’s a problem that’s gained growing attention over the past few decades, as public health experts have worked to untangle the causes of these disparities, and to find ways of mitigating their effects. Now those efforts face serious headwinds, with federal funding cuts and pressure against DEI measures threatening to roll back progress. But in the face of these challenges, providers are doubling down on offering care that builds trust and delivers better outcomes. On this special production of The Pulse, we find out what that work looks like on the ground. From becoming an ally to patients to mentoring the next generation of Black physicians, we’ll hear how providers are expanding access to quality care. We’ll also explore how the birth of Medicare led to the desegregation of hospitals.

Dr. Fatima Cody Stanford is changing the way we talk about obesity, and how we treat it. She explains why she got into obesity medicine in the first place, why she never gives her patients a goal weight, and how being invited to a patient’s 90th birthday party was a great reminder of why her work matters.

Pulse producer Nichole Currie gets into the kitchen with her aunt Gladys McLean to learn how to enjoy traditional Southern recipes while eating a healthy and nutritious diet.

Physician, surgeon, and now-congressional candidate Ala Stanford gained national recognition during the pandemic, when she stepped up to provide COVID testing, and later vaccines, to underserved communities. She talks about how her own upbringing shaped her as a physician and leader —- and why increasing access and trust are key for better care.
