  1. The Complexity of Motherhood

    The Complexity of Motherhood

    How do you sum up the experience of motherhood, and all of the changes it brings, both big and small? It’s a transformation that affects everything — hormones, body image, relationships, feelings, money, career — even the answers to larger, existential questions like, “Who am I in this world, and what is my role?” On this episode, we explore the impact of motherhood. We talk with a psychologist about “matrescence” — a term used to describe the multi-faceted transformation ushered in by motherhood — and why it comes as a surprise to so many mothers. We find out how motherhood rewires the brain, and how those changes affect the way we think and behave. And we hear about a new play that challenges ideas about motherhood and women’s health. After interviewing women about their experiences of motherhood, Aurélie Athan came across a term that seemed to describe all of the changes: Matrescence. Athan is a reproductive psychologist and a professor at Teachers College at Columbia University in New York City. When health-and-science journalist Chelsea Conaboy first became a mother, she was surprised to find that the maternal instinct she’d heard about for years wasn’t kicking in. That led Conaboy to investigate some of our long-held beliefs about motherhood — and how they influence our ways of thinking and behaving. Her book is called “Mother Brain: How Neuroscience Is Rewriting the Story of Parenthood.” We talk with writer and actor Andrea Peterson about her new play, (plan c) — a dark comedy that explores the gray areas of motherhood, from medical issues to fears about maintaining independence to relationship troubles. The world premiere of (plan c) with Pygmalion Productions is running now at the Rose Wagner Black Box Theater in Salt Lake City, Utah. When Katie Pratt was 3 years old, she was diagnosed with a Chiari malformation, a rare brain condition in which the cerebellum bulges through an opening in the skull into the spinal canal. Katie’s mom, Wendy, had a hunch about what the solution would be — but it wasn’t until doctors opened up Katie’s skull that they discovered she was right. Katie interviews her mom about the experience, and her incredible flash of mother’s intuition.

    Healing with Psychedelics: Veterans, PTSD, and the Science of Mind-Altering Drugs

    For decades, psychedelics like LSD, psilocybin, and MDMA were regarded as dangerous drugs of abuse — but that’s started changing as research increasingly reveals their ability to help treat serious mental health issues. On this episode, we listen back to past conversations about the science behind these drugs’ therapeutic potential, along with powerful stories of healing. When Marcus Capone retired from the Navy SEALS in 2013 after more than a decade of service, he found himself at loose ends, and battling a deep depression. He cycled through antidepressants and other prescription medications, but nothing worked — until his wife suggested a radical alternative: psychedelic-assisted therapy. Capone describes his experience with ibogaine, how it changed him, and why he thinks it worked when nothing else did. Capone is the co-founder and chairman of VETS: Veterans Exploring Treatment Solutions, and is featured in the documentary “In Waves and War” now on Netflix. Psychiatrist and researcher Rachel Yehuda explains the science behind psychedelic-assisted therapy, and what she’s learned about its potential to treat PTSD in veterans. She leads the PTSD clinical research program at the James J. Peters VA Medical Center in New York City. MDMA — otherwise known as ecstasy or molly — is best known as a party drug, but in recent years, scientists have begun investigating it as a treatment for PTSD. We talk with science journalist Rachel Nuwer about the history of MDMA, the science behind its therapeutic potential, and how it helped change one woman’s life. Nuwer’s book is called “I Feel Love: MDMA and the Quest for Connection in a Fractured World.” Cluster headaches can be debilitating — but a little over a decade ago, a group of sufferers, who call themselves “Clusterbusters,” began investigating the potential of psilocybin, otherwise known as magic mushrooms, to treat their intractable pain. We talk with sociologist Joanna Kempner about her research into the group and their mission, documented in her book “Psychedelic Outlaws: The Movement Revolutionizing Modern Medicine.”

    What Greenland Can Teach Us About The Earth’s Past and Future

    Politicians are eyeing Greenland as an important strategic location, perfectly situated between Europe and North America. President Donald Trump has said he remains highly interested in acquiring or controlling Greenland as a national security and economic asset. But for a lot of researchers, Greenland is a beautiful and fragile place that holds important clues to the Earth’s past and future. So what are they learning about the large, icy island?  On this episode, we’ll explore some of the research happening in Greenland. We’ll hear about archeologists digging up Viking graves to find out why a settlement disappeared sometime in the 15th century, and talk to an adventurous climate scientist who tracks and follows meltwater that’s flowing from Greenland’s ice sheet into the sea. Also, what are the riches buried under the ice that everybody is interested in? We’ll find out how mining for Greenland’s rare earth metals could affect this ecosystem. We talk with writer and photographer Neil Shea about his travels to Greenland and the intriguing historical mystery he found there — the Viking settlement that thrived and then vanished 500 years later. Shea explains how and why Erik the Red first pioneered the settlement, the global shifts that put them into decline, and lingering clues as to how and why they disappeared. Shea’s book about his Arctic adventures is “Frostlines: A Journey Through Entangled Lives and Landscapes in a Warming Arctic.” President Trump's intense interest in Greenland has raised the question — what is it about Greenland that makes it so valuable? One answer, according to journalist Vince Beiser, is its rare earth metals. We talk with Beiser about what makes these metals so valuable, the challenges involved with mining them, and his predictions for what will happen next. Beiser's book is “Power Metal: The Race for the Resources That Will Shape the Future.” Greenland isn’t just valuable strategically and economically — it’s also a key hub for research on climate change. We talk with Rutgers University geography professor Åsa Rennermalm about why Greenland — and, in particular, its massive ice sheet — is so important to this research, her experiences roughing it in the tundra, and what the recent political discourse could mean for the future of her research.

    Inside the Boom of Urgent Care: How It’s Changing American Medicine

    The number of urgent care centers in the U.S. has doubled over the past decade, and it isn’t hard to see why — they fill a void in the market. Urgent care offers quick and convenient access to medical care when patients can’t get an appointment to see their primary care doctor, but their issue doesn’t seem to warrant an ER visit. But the rapid rise of urgent care has come with some growing pains — questions over the quality of care, and how they’re affecting doctor-patient relationships. On this encore episode, we explore the rise of urgent care. We hear about what draws providers to urgent care, and how they feel about the work; the role of private equity funding; and why some specialty care providers are borrowing from this model. Comedian Aaron Weber talks about his popular bit on urgent care — and what kind of response he got from audience members who work in the industry. Urgent care may occupy an important niche in the health care ecosystem, but let’s be honest — it isn’t the sexiest job. So what makes physicians and other providers decide to work in urgent care? Pulse reporter Liz Tung talked with some of them to find out. We usually think of urgent care centers as handling minor issues like cuts, scrapes, and colds — but recently, some centers have been springing up that cater to specialized needs. Pulse producer Nichole Currie explores the emergence of urgent care centers for cancer patients. Mayo Clinic neurologist Joseph Servin explains what urgent cares reveal about our fragmented health care system, and why it can be a bad thing when they become neurology patients’ first stop.

    The Problem with Being Perfect: How Unrealistic Standards Hurt Our Minds and Bodies

    We often think of perfectionism as a virtue; a kind of shorthand for high standards, a solid work ethic, and attention to detail. But in reality, perfectionism can be a paralyzing force — like sand wedged in the gears of our minds. It slows us down, makes us question our choices, and traps us in an endless cycle of tweaking and re-tweaking, unable to move on to the next task. It can even have consequences for our health, as we push ourselves beyond our limits, in pursuit of impossible standards. And it’s on the rise, especially among teens and young adults. On this episode, we explore what causes perfectionism, how we can escape its grip, and why letting go of unrealistic expectations doesn’t have to mean abandoning excellence. We hear from recovering perfectionists about what finally forced them to let go of their impossible  standards, and how their lives have changed since. We talk with a longtime perfectionism researcher about what’s at the root of perfectionism, and some of its more dire consequences. And we learn about a new movement that’s pushing high school kids to invest less in their academic achievements — and more in how they matter to others. For most of her life, Gitanjali Trevorrow-Seymour was a perfectionist — and as an adult, her exacting standards seemed to have paid off, in the form of a successful career, beautiful home, and loving family. But a few years ago, she reached a turning point that prompted her to question her pursuit of perfection — and the toll it was taking on her life and health. We talk with Trevorrow-Seymour about what finally caused her to change, and what it’s like living on the other side of perfectionism. It’s something we all hear as kids: “Practice makes perfect.” But for budding cellist Joshua Roman, it was more than just a saying — it was the only way to become the best. His relentless work ethic  paid off when, at the tender age of 22, Roman became the youngest lead cellist in the Seattle Symphony Orchestra’s history. But everything changed for Roman several years ago, when he contracted a debilitating case of long COVID, and found himself struggling to function. Pulse producer Nichole Currie talks with Roman about how his newfound limitations have changed his life and forced him to face his perfectionism. Researcher Gordon Flett breaks down the dark side of perfectionism — from burnout to health effects — explaining where it comes from, why it’s on the rise in young people, and how to deal with it. Flett is a professor emeritus of psychology at York University in Toronto, and the author of several books on perfectionism. For a lot of high school kids, college admissions are a major driver of stress — not to mention depression, anxiety, and low self-esteem. Pulse reporter Alan Yu talks with perfectionism researchers about the dangers of America’s “achievement culture,” along with journalist Jennifer Wallace about a potential solution — the Mattering Movement.
