We are in the midst of a global mental health crisis, and mental illnesses are on the rise. But what causes mental illness? And why are mental health problems so hard to treat? Drawing on decades of research, Harvard psychiatrist Dr. Chris Palmer outlines a revolutionary new understanding that for the first time unites our existing knowledge about mental illness within a single framework: mental disorders are metabolic disorders of the brain. Brain Energy will transform the field of mental health, and the lives of countless people around the world.

Richard Dawkins' brilliant reformulation of the theory of natural selection has the rare distinction of having provoked as much excitement and interest outside the scientific community as within it. His theories have helped change the whole nature of the study of social biology, and have forced thousands to rethink their beliefs about life.

Hilarious, fascinating, and a roller coaster of dizzying, historical what-ifs, Napoleon's Hemorrhoids is a potpourri for serious historians and casual history buffs. In one of Phil Mason's many revelations, you'll learn that Communist jets were two minutes away from opening fire on American planes during the Cuban missile crisis, when they had to turn back as they were running out of fuel. You'll discover that before the Battle of Waterloo, Napoleon's painful hemorrhoids prevented him from mounting his horse to survey the battlefield.

In Your Brain Is a Time Machine, brain researcher and best-selling author Dean Buonomano draws on evolutionary biology, physics, and philosophy to present his influential theory of how we tell and perceive time. The human brain, he argues, is a complex system that not only tells time but creates it; it constructs our sense of chronological flow and enables "mental time travel" - simulations of future and past events.

How do today's most successful tech companies - Amazon, Google, Facebook, Netflix, Tesla - design, develop, and deploy the products that have earned the love of literally billions of people around the world? Perhaps surprisingly, they do it very differently from the vast majority of tech companies. In Inspired, technology product management thought leader Marty Cagan provides listeners with a master class in how to structure and staff a vibrant and successful product organization and how to discover and deliver technology products that your customers will love.

Dr. Arline T. Geronimus coined the term “weathering” to describe the effects of systemic oppression—including racism and classism—on the body. In Weathering, based on more than 30 years of research, she argues that health and aging have more to do with how society treats us than how well we take care of ourselves. She explains what happens to human bodies as they attempt to withstand and overcome the challenges and insults that society leverages at them, and details how this process ravages their health. And she proposes solutions.

How do we understand nature? Benevolent and supportive? Wild and threatening? Reassuring or unpredictable? We all have a different experience of, and relationship with, nature. This audiobook includes immersive sound design to further ground the listener in nature and complement the lessons explored in the narration.

Hannah Arendt would’ve recognized the extremes of our century from her own: the disenchantment with politics; the rise of conspiracy theories; self-censorship; powerlessness; racism; mass displacement; tyranny and occupation. She had lived through it already.

What is life? This is among the most difficult open problems in science, right up there with the nature of consciousness and the existence of matter. All the definitions we have fall short. None help us understand how life originates or the full range of possibilities for what life on other planets might look like. In Life as No One Knows It, physicist and astrobiologist Sara Imari Walker argues that solving the origin of life requires radical new thinking and an experimentally testable theory for what life is.

Why do we assume romantic relationships are more important than friendships? What do we lose when we expect a spouse to meet all our needs? And what can we learn about commitment, love, and family from people who put deep friendship at the center of their lives? In The Other Significant Others, NPR's Rhaina Cohen invites us into the lives of people who have defied convention by choosing a friend as a life partner—these are friends who are home co-owners, co-parents or each other’s caregivers.

Poetry and science, as Popova writes in her introduction, "are instruments for knowing the world more intimately and loving it more deeply." In 15 short essays on subjects ranging from the mystery of dark matter and the infinity of pi to the resilience of trees and the intelligence of octopuses, Popova tells the stories of scientific searching and discovery. These stories are interwoven with details from the very real and human lives of scientists—many of them women, many underrecognized—and poets inspired by the same questions and the beauty they reveal.

Sensitively introduced and edited by Kate Edgar, Sacks’s longtime editor, the letters deliver a portrait of Sacks as he wrestles with the workings of the brain and mind. We see, through his eyes, the beginnings of modern neuroscience, following the thought processes of one of the great intellectuals of our time, whose words, as evidenced in this book, were unfailingly shaped with generosity and wonder toward other people.

In 2018, lumps of frozen soil, collected from the bottom of the world's first deep ice core and lost for decades, reappeared in Denmark. When geologist Paul Bierman and his team first melted a piece of this unique material, they were shocked to find perfectly preserved leaves, twigs, and moss. That observation led them to a startling discovery: Greenland's ice sheet had melted naturally before, about 400,000 years ago.

With the imagery of a poet and the reflection of a philosopher, David Whyte turns his attention to 52 ordinary words, each its own particular doorway into the underlying currents of human life. Beginning with "Alone" and closing with "Work", each chapter is a meditation on meaning and context, an invitation to shift and broaden our perspectives on the inevitable vicissitudes of life: pain and joy, honesty and anger, confession and vulnerability, the experience of feeling besieged and the desire to run away from it all.

This fascinating yet disquieting audiobook finds that we are running out of dirt, and it's no laughing matter. An engaging natural and cultural history of soil that sweeps from ancient civilizations to modern times, Dirt: The Erosion of Civilizations explores the compelling idea that we are, and have long been, using up Earth's soil. Once bare of protective vegetation and exposed to wind and rain, cultivated soils erode bit by bit, slowly enough to be ignored in a single lifetime but fast enough over centuries to limit the lifespan of civilizations.

Earth has been reinventing itself for more than four billion years, keeping a record of its experiments in the form of rocks. Yet most of us live our lives on the planet with no idea of its extraordinary history, unable to interpret the language of the rocks that surround us. Geologist Marcia Bjornerud believes that our lives can be enriched by understanding our heritage on this old and creative planet. Contrary to their reputation, rocks have eventful lives—and they intersect with our own in surprising ways.

Many of us feel trapped in a grind of constant change: rolling news cycles, the chatter of social media, our families split along partisan lines. We feel fearful and tired, on edge in our bodies, not quite knowing what has us perpetually depleted. For Katherine May, this low hum of fatigue and anxiety made her wonder what she was missing. Could there be a different way to relate to the world, one that would allow her to feel more rested and at ease, even as seismic changes unfold on the planet?

The Light Eaters is a deep immersion into the drama of green life and the complexity of this wild and awe-inspiring world that challenges our very understanding of agency, consciousness, and intelligence. In looking closely, we see that plants, rather than imitate human intelligence, have perhaps formed a parallel system.

Sometimes you slip through the cracks: unforeseen circumstances like an abrupt illness, the death of a loved one, a breakup, or a job loss can derail a life. These periods of dislocation can be lonely and unexpected. For May, her husband fell ill, her son stopped attending school, and her own medical issues led her to leave a demanding job. Wintering explores how she not only endured this painful time, but embraced the singular opportunities it offered. Ultimately Wintering invites us to change how we relate to our own fallow times.

Addressing the fundamental questions about how to live, Meditations for Mortals offers a powerful new way to take action on what counts: a guiding philosophy of life Oliver Burkeman calls “imperfectionism.” It helps us tackle challenges as they crop up in our daily lives: our finite time, the lure of distraction, the impossibility of doing anything perfectly.
