Closing the Gap: Improving Health Outcomes for Black Americans

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.

From Buzz to Burnout: How Alcohol Affects the Brain and Body

At the best of times, alcohol makes us feel great — relaxed and gregarious, warm and fuzzy, happy and confident. But at the worst of times, it can morph into a serious problem, damaging our relationships, our health, and our lives as a whole. As we close out Dry January, a popular movement to abstain from drinking for a month, we explore our relationship with alcohol. Why we consume it, how it affects us, and when it’s time to quit. We talk with surgeon and recovering alcoholic Charles Knowles about how booze affects our brains and health, and what finally pushed him to go sober for good; we hear about a trend known as “California sober,” and why so many people are embracing it; and we find out how zero-proof cocktail bars are helping some people socialize while sober. Charles Knowles was barely a teen when he discovered the power of alcohol to transform him from a shy outsider into the life of the party. But as he got older, and sank deeper into drinking, alcohol stopped being fun — and started affecting his health and his life. We talk with Knowles, a surgeon and physician, about what makes some people more vulnerable to problematic drinking, how alcohol affects our brains, and how his life changed once he stopped drinking. Knowles’ new book is “Why We Drink Too Much: The Impact of Alcohol on Our Bodies and Culture.” For a lot of former drinkers, "sobriety" means total abstinence — no alcohol, or any other substances that produce a similar buzz. But recently, a new, more permissive version of sobriety has been gaining popularity: "California sober." It involves embracing cannabis and psychedelics as a means of avoiding alcohol and hard drugs. Reporter Andrew Stelzer tracks the origins of this phenomenon, why some people find it helpful, and what researchers have to say about it.. One of the hardest parts about sobriety for a lot of people is dealing with the social impact. Not only is alcohol a social lubricant — it’s often at the center of social events themselves. But recently, some entrepreneurs have been creating alternatives in the form of zero-proof cocktail bars. Pulse reporter Alan Yu visits Philadelphia’s Bar Palmina to find out who goes there, and why.

Challenger at 40: How the Disaster Shaped the Future of NASA

On January 28, 1986, a frigid cold day with an icy blue sky, the Space Shuttle Challenger exploded just 73 seconds after launching from Cape Canaveral, Florida. The accident killed all seven crew members aboard and was the first fatal in-flight spacecraft disaster in NASA's history. For many, the explosion came as an absolute shock. Millions of people were watching live, including school children who were especially eager to catch a glimpse of Christa McAuliffe, a teacher from New Hampshire and the first civilian in space. On this episode, we remember the Challenger tragedy with author Adam Higginbotham who details what went wrong and the aftermath in his book, “Challenger: A True Story of Heroism and Disaster on the Edge of Space.”

Triumph, Tragedy and Ennui: Three NASA Missions That Shaped the Future of Space Exploration

Space exploration relies heavily on the interest of the public — the voters, and taxpayers, who are ultimately footing the bill. But that support and excitement can be fickle. When space missions go well, and deliver new insights, the payoff is cheering crowds and increased support. But when they don’t, the result can be reduced funding, canceled missions — and even deaths. That means, with each mission, the pressure is on to push boundaries, break new ground, and get everything right. Even a small mistake or malfunction could potentially lead to absolute disaster. On this episode, we look back at three historic NASA missions and how they shaped the course of space exploration. From the awe-inspiring triumph of the first spacecraft landing on Mars in 1976, to a devastating national tragedy in 1986, to the long-game Pluto mission launched in 2006. It was the mission that was supposed to reignite the public's interest in the work of NASA — the Space Shuttle Challenger, an orbiter that, in January 1986, would carry six astronauts and one civilian, a teacher named Christa McAuliffe, into space. But on the day of lift-off, tragedy struck — the Challenger exploded 73 seconds after launch, killing all seven crew members. We talk with author Adam Higginbotham about what led up to the mission, what went wrong, and the lasting impact it had on both NASA and the public's perception of space exploration. He’s the author of “Challenger: A True Story of Heroism and Disaster on the Edge of Space.” In 2006, NASA launched New Horizons — an interplanetary space probe slated to become the first spacecraft to perform a flyby of Pluto, a journey of roughly 10 years. Pulse reporter Alan Yu tells the story of the mission's difficult beginnings, what we learned, and the dramatic moment that almost derailed everything.

The Weird Menopause Symptoms No One Ever Told You About — And How to Treat Them

If you go by pop culture depictions, menopause seems like no big deal — a few hot flashes, some comical bouts of hormone-fueled rage, and the “big change,” as it was once called, is over. But for many of the 2 million American women who enter menopause each year, the symptoms can be a lot more serious and long-lasting, ranging from vertigo and joint pain to brain fog and heart problems. On this episode, we take a deep dive into perimenopause and menopause – what’s going on biologically? What can be done to ease symptoms? And why do so many women struggle to receive help from their doctors? We talk with menopause experts about hormone replacement therapy, and why it was demonized for many years; find out what researchers have discovered about the causes of brain fog; and hear about new efforts to deal with medically induced menopause. In this excerpt from our live event, Reimagining Menopause, host Maiken Scott talks with two certified menopause providers — Robyn Faye, an OB-GYN at Jefferson Health in Philadelphia, and Arina Chesnokova, assistant professor in of Obstetrics and Gynecology at the University of Pennsylvania’s Perelman School of Medicine — about the ins and outs of hormone therapy, which symptoms it alleviates, when it’s safe and when it’s not. Watch the full discussion here. Reporter Alan Yu talks with researchers about what’s behind one of the most vexing symptoms of menopause for many women — brain fog. For women who have cancer when they’re younger, especially breast or ovarian cancer, chemotherapy and other medications needed to treat the disease can affect hormones - and suddenly plunge them into menopause, years before they might naturally experience it. We explore what their options are, and why so many say they were not prepared for this change.

From Soy to Carbs: How Food can Ease Menopause Symptoms

Capsule wardrobes have become a popular way to streamline and organize your closet — basically, paring it down to a few staple pieces that you can combine in multiple ways, and freshen up with seasonal accessories. Registered Dietitian Jenn Salib Huber says this is how women should think about nutrition during perimenopause and menopause. Rather than obsessing over calorie counts and macronutrients, they should focus on staples like soy and fish that are not only delicious but can also alleviate symptoms like hot flashes or brain fog. Huber joins us to discuss her new cookbook, “Eat to Thrive During Menopause.” She offers advice for getting the most out of your meals, tells us which ingredients are “must-haves” during menopause, and shares some of her favorite recipes.

Engineering Happiness into our Daily Lives

Think about the last time you were really happy — where were you? What were you doing? Who were you with? And, most importantly, how can you recreate that feeling? Happiness can feel like lightning in a bottle — beautiful in the moment, but hard to find and harder yet to sustain. So what is it that makes for a happy life? And how do we engineer our lives for greater contentment, fulfillment, and joy? On this episode: the science of happiness and how we can experience more of it every day. We talk with psychologist Eric Zillmer about why certain places bring us joy, and how to engineer happiness in our lives. We hear about one reporter’s experiment to bring more moments of serendipity in her life. And, writer Daniel Coyle explains why community is at the heart of what it means to flourish. Drexel University psychologist Eric Zillmer created a “happiness map” of Philadelphia with the help of his students. He says it holds greater lessons on why certain places bring us joy, and how we can reverse-engineer happiness into our days. Zillmer directs the happiness lab at Drexel University. Writer Daniel Coyle built his career on exploring what it is that makes people successful — but when both of his parents died a few years ago, Coyle found himself unmoored, questioning what makes for a happy and meaningful life. The resulting journey led to his newest book, “Flourish: The Art of Building Meaning, Joy, and Fulfillment.” We talk with Coyle why he says community is at the heart of flourishing, how to create the right conditions for happiness, and why he says life isn’t a treasure hunt — it’s the process of treasure creation.

How Noise Affects Our Health

For a lot of us, noise is a constant factor — an inescapable soundtrack playing on loop in the background. Kids screaming, sirens blaring, the roar of traffic, the sounds of music, lawn mowers, construction, and so much more. We ignore it when we can, or wear headphones to block out the racket. But all that noise can actually damage our hearing and, subsequently, our overall health. On this encore episode, we explore what researchers are learning about the connections between noise, hearing loss, and our well-being. We find out whether constant headphone listening could put our hearing at risk, and why live concerts are so loud, along with how to protect your ears. Also, why stigma remains around hearing aids, even though so many people need them. SHOW NOTES: We talk with exposure scientist Rick Neitzel about the long-neglected topic of noise pollution and its effects on our health. He explains the physiological effects of noise, theories on how it causes harm, and some of the most common sources of damaging sound exposure. Meg Wallhagen — a geriatric nurse practitioner and hearing loss researcher — explains age-related hearing loss, and why there still remains a stigma against hearing aids.

Of all the podcasts I subscribe to (mostly public radio shows, but not exclusively), “The Pulse” is the one I find consistently interesting and worth hearing to the episode’s end. The subject matter is fresh, even unexpected at times, and well produced. The host, Maiken Scott, is easy to listen to. Other podcast producers, who seem to think just throwing a couple talkers before a microphone to improvise, would do well to study this one to see how it’s done.
Illegally fired its talent and lost

Ted Post

The Pluse and WHYY illegally fired one of their staff for having his own stand up show. Then they wasted hundreds of thousands of dollars of listener’s donated funds on lawyers to fight this. Well, WHYY and The Pulse lost! Amazingly disappointing that an NPR member station would spend its funds fighting its own employees union.
HSCT works for MS

Thank you for sharing Jessie’s story. This could have been my story…except my husband has stayed by my side throughout my MS journey. I went to Mexico in April 2017 for HSCT. I had been living with MS for over 16 years and didn't fit the trial criteria in the US. There are thousands of us who have gone and are doing great! Dr Ruiz is using a non-myelo protocol because it is less risky and still highly effective. I have been off all meds for 4 and a half years, I can run or bike for miles, lift weights and have no MS progression, my MRIs are stable. Freedman is uninformed and can’t accept that his theories are wrong!
Evolved in the wrong direction

I started listening years ago, the topics are always interesting, showing things under various lights. It’s been almost a year that the quality has declined. Each story told to illustrate a topic drags on for 10-15 min before getting to the point, not bringing anything interesting to the table while doing so. Each episode has become a drag. Sad, as this show used to be so interesting.
