248. Mariah Blake with Mónica Guzmán: A Legacy of Chemicals & Cover-Ups
From Silent Spring to Erin Brockovich, people have been captivated — and devastated — by stories of harmful chemicals and the many ways that they have altered and even ended human lives. From investigative journalist Mariah Blake comes a new book that recounts a small town being poisoned, a corporate cover up, and a grassroots movement to fight back. In 2014, after losing several friends and relatives to cancer, an insurance underwriter in Hoosick Falls, New York, suspected that the local water supply was polluted. When he tested his tap water, he discovered dangerous levels of “forever chemicals” (synthetic chemicals that are resistant to breaking down and can lead to adverse health and environmental effects). This set off a chain of events that revealed at least 100 million Americans’ drinking water was tainted. The discovery of bad water was a shock to some, but perhaps more shocking was the discovery that the United States government and the manufacturers of these toxic chemicals — used in everything from cookware to lipstick to children’s clothing — had known about these hazards for decades but had hidden them from the public. In her new book They Poisoned the World, investigative journalist Mariah Blake tells this story, tracing its roots all the way back to the Manhattan Project and through the postwar America. Drawing on years of reporting and tens of thousands of documents, Blake weaves the history of forever chemicals with the story of how a lone village took on the chemical giants all the way to the nation’s capital — and won. Mariah Blake is an investigative journalist whose writing has appeared in The Atlantic, Mother Jones, The New Republic, and other publications. She was a Murrey Marder Nieman Fellow in Watchdog Journalism at Harvard University. Mónica Guzmán is author of I Never Thought of it That Way: How to Have Fearlessly Curious Conversations in Dangerously Divided Times; founder and CEO of Reclaim Curiosity; Senior Fellow for Public Practice at Braver Angels; and host of A Braver Way podcast. Mónica serves on the Board of Directors for the Institute for Multipartisan Education. She received an honorary doctorate degree from Wheaton College, and completed study and research fellowships at the Nieman Foundation for Journalism at Harvard, the Henry M. Jackson Foundation, and the University of Florida. A Mexican immigrant, Latina, and dual US/Mexico citizen, she lives in Seattle with her husband and two kids and is the proud liberal daughter of conservative parents.

244. Mary-Frances O’Connor with Dr. Anthony Back: Grief and the Body
Despite grief being one of the most universal of human experiences, there is still much that we do not know about it. Can we die of a broken heart? What happens in our bodies as we grieve; how do our coping behaviors affect our physical health, immunity, and even cognition? While we may be more familiar with psychological and emotional ramifications of loss and sorrow, we often overlook its impact on our physical bodies. In The Grieving Body: How the Stress of Loss Can Be an Opportunity for Healing, the follow-up to its successful predecessor The Grieving Brain (2022), grief expert, neuroscientist, and psychologist Dr. Mary-Frances O’Connor focuses on how the painful ordeal of grief impacts the body. O’Connor shares scientific research, charts, and graphs coupled with personal stories, revealing new insights on grief’s physiological impact and helping illuminate the toll that loss takes on our cardiovascular, endocrine, and immune systems and the larger implications for our long-term well-being. The Grieving Body is for anyone who has experienced loss and who may want to learn more about what they are going through and how to support them. Mary-Frances O’Connor, PhD, is a professor of psychology at the University of Arizona, where she directs the Grief, Loss and Social Stress (GLASS) Lab, investigating the effects of grief on the brain and the body.

240. Amorina Kingdon: Sing Like Fish – How Sound Rules Life Underwater
The ocean has proven endlessly mysterious and fascinating to all manner of people across the globe, but for centuries true knowledge of the depths was simply out of reach. As modern technologies advance, science has debunked much once held to be true – including the idea of the “silent world” of the ocean. What was once thought to be a muffled marine landscape with little to no perceptible sounds has now been revealed to be a complex interplay of aquatic acoustics. In her debut book Sing Like Fish: How Sound Rules Life Under Water, science journalist Amorina Kingdon turns up the volume on groundbreaking discoveries in ocean soundscapes, why this research is important to our ecosystems, and how human impact is playing more of a role than science realized. Sing Like Fish explores how the complexity of oceanic noise goes far deeper than the familiar hits like whale song and crashing currents. Sound travels four times faster in water than in air and its reach in environmental impact is as expansive as the seas themselves. Kingdon educates readers on a plethora of natural sonic relationships that have been recorded under the surface – from individual snapping shrimp and communicating fish to rumbling seismic activity bouncing off the seafloor in regions light cannot reach and the biodiversity concerts that live as coral reefs. These revelations also cast into sharp relief the repercussions of humanity’s presence in our seas. Marine noise pollution takes the form of everything from recreational boating and cruise tourism to the global shipping industry to military forces and oil exploration. As science continues to uncover the splendor and nuance of the ocean as an audible entity, Sing Like Fish reinforces the importance of understanding, protecting, and reveling in the symphony of our seas. Amorina Kingdon is an award-winning writer and science journalist with a focused fascination in marine biology and coastal environments. She previously served as staff writer and contributor to Hakai Magazine. Her science writing has been anthologized in Best Canadian Essays 2020 (Biblioasis), and her fiction works have been included in PRISM Magazine, Flash Fiction Magazine, and Speculative North.

239. Lynne Peeples with Bill Radke: Shining New Light on Our Rest and Routines
Whether it’s staying up late in front of the screens or waking up before dawn for that early morning flight – it’s easy to tell when something big has thrown off our routines. But what about the little things that add up over the course of a day, a week, or our lives overall? How do small adjustments to our daily practices affect our long-term relationship with the balance between our bodies and the busy technology-driven world we live in? In her new book, author and science journalist Lynne Peeples explores how our often hectic habits can impact our physical, mental, and social health. The Inner Clock: Living In Sync with Our Circadian Rhythms peeks behind the blackout curtains to consider how learning more about our internal systems could help provide an extra boost to ourselves, our performance, and our planet. Drawing from emerging new fields of research and exciting first-hand experiments, Peeples seeks to understand how the science of circadian rhythms could potentially be applied to a wide range of areas. How could taking a walk in the morning and going to bed at the same time each night keep your body in sync? Why are some doctors prescribing treatments at specific times of day? And how might a better understanding of our circadian rhythms improve educational outcomes, optimize sports performance, and support the longevity of our planet? From jet lag and time zones to artificial light and underground bunkers to new perspectives on mental illness treatment and more, The Inner Clock encourages readers to hone their senses toward what really makes our internal clocks tick and how we may be able to reset them for the better. Lynne Peeples is an author and journalist exploring the fields of science, health, and the environment. Peeples has appeared on platforms including MSNBC, HuffPost Live, BBC News, Nature Podcast, and more.
