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 encore 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.”

Erica Gerard tried to find the right antidepressant for over two decades, one where the benefits outweighed the side effects. Finally, she decided to get off her medication. 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 prescribed Prozac in college after years of feeling sad, lonely and disconnected from her peers. The medication helped — but it also left her constantly exhausted and feeling as though she was watching her own life from behind a screen. After more than two decades, she decided she wanted to stop taking the medication. She documented her journey for The Pulse, and what she learned about tapering off safely.

A new federal initiative aimed at getting Americans off antidepressants has put a spotlight on this issue. Psychiatrist Jonathan Slater joins us to discuss the complexities of de-prescribing these medications. He says there’s a lack of training and guidelines for tapering off safely, adding that the process requires individualized, monitored care with psychological support. 

When a mental health issue made it impossible for British author Madeline Dyer to focus on her writing career, a physician suggested she should try an antidepressant. She was reluctant to give it a shot, fearing it would make her less creative. The medication ended up helping her a lot, but she says it impacted her genre of choice.

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, our relationships with others, and life trajectories and careers. Vieten joins us to talk about her research, and her new book, “Imagine That: Transform How You Think, Feel, and Live with the Science of Imagination.”

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 writer David Epstein about his new book “Inside the Box: How Constraints Make Us Better.”
He explains how restrictions led to the invention of everything from impressionism to the iPod, and how to develop rules and limits for your own creative work that could encourage innovation.

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. We explore how emotions, stress, sleep, and diet impact pain, a new option for easing labor pain, and emerging research that could reduce the addictive properties of opioids.

We often think of pain as a physical ailment — but newer research shows that pain has as much to do with our brains as it does our bodies. We talk with pain researcher and psychologist Rachel Zoffness about how emotions shape — and construct — our experience of pain, and how identifying the unique biopsychosocial factors contributing to pain can ultimately help patients overcome it. Her new book is "Tell Me Where It Hurts: The New Science of Pain and How to Heal."

Giving birth is one of the most painful things many people will experience — which is why a majority of expectant mothers choose epidurals, IV opioids, or both to manage their pain. But recently, another option has been making its way into the delivery room— nitrous oxide, also known as laughing gas. Reporter Andrew Stelzer explains how N02  stacks up against its competitors, and why a growing number hospitals in the U.S. are offering it as an option.

Opioids work well on all kinds of pain — but, as the last few decades have shown, they also pose a severe risk of addiction. We talk with neuroscientist and addiction researcher Anjali Rajadhyaksha about a recent discovery that could make opioids safer.
