If forests are the lungs of the planet, then animals migrating across oceans, streams, and mountains—eating, pooping, and dying along the way—are its heart and arteries, pumping nitrogen and phosphorus from deep-sea gorges up to mountain peaks, from the Arctic to the Caribbean. Without this conveyor belt of crucial, life-sustaining nutrients, the world would look very different.

Charles Darwin’s theories, first published more than 150 years ago, still set the paradigm of how we understand the evolution of life—but scientific advances of recent decades have radically altered that understanding. In fact the currently accepted history of life on Earth is flawed and out of date. Now two pioneering scientists, one already an award-winning popular author, deliver an eye-opening narrative that synthesizes a generation’s worth of insights from new research.

In Waves in an Impossible Sea, physicist Matt Strassler tells a startling tale of elementary particles, human experience, and empty space. He begins with a simple mystery of motion. When we drive at highway speeds with the windows down, the wind beats against our faces. Yet our planet hurtles through the cosmos at 150 miles per second, and we feel nothing of it. How can our voyage be so tranquil when, as Einstein discovered, matter warps space, and space deflects matter? The answer, Strassler reveals, is that empty space is a sea, albeit a paradoxically strange one.

When we talk about human history, we often focus on great leaders, population forces, and decisive wars. But how has the earth itself determined our destiny? Our planet wobbles, driving changes in climate that forced the transition from nomadism to farming. Mountainous terrain led to the development of democracy in Greece. Atmospheric circulation patterns later on shaped the progression of global exploration, colonization, and trade. Even today, voting behavior in the southeast United States ultimately follows the underlying pattern of 75 million-year-old sediments from an ancient sea.

In Bite, zoologist Bill Schutt makes a surprising case: it is teeth that are responsible for the long-term success of vertebrates. The appearance of teeth, roughly half a billion years ago, was an adaptation that allowed animals with backbones, such as fish, amphibians, reptiles, birds, dinosaurs and mammals—including us—to chow down in pretty much every conceivable environment.

Robert Macfarlane brings his glittering style to a profound work of travel writing, reportage, and natural history. Is a River Alive? is a joyful, mind-expanding exploration of an ancient, urgent idea: that rivers are living beings who should be recognized as such in imagination and law. Macfarlane takes listeners on three unforgettable journeys teeming with extraordinary people, stories, and places: to the miraculous cloud-forests and mountain streams of Ecuador, to the wounded creeks and lagoons of India, and to the spectacular wild rivers of Canada.

The past is past, but it does leave clues, and Thomas Halliday has used cutting-edge science to decipher them more completely than ever before. In Otherlands, Halliday makes sixteen fossil sites burst to life.

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.

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.

Dip below the ocean’s surface and you are soon confronted by forms of life that could not seem more foreign to our own: sea sponges, soft corals, and serpulid worms, whose rooted bodies, intricate geometry, and flower-like appendages are more reminiscent of plant life or even architecture than anything recognizably animal. Yet these creatures are our cousins. As fellow members of the animal kingdom — the Metazoa— they can teach us much about the evolutionary origins of not only our bodies, but also our minds.

The world is changing at a relentless pace. How can we slow down and act from a place of respect for all living things? The Sacred Balance shows us how.

The James Webb Space Telescope is transforming the universe right before our eyes—and here, for the first time, is the inside account of how the mission originated, how it performs its miracles of science, and what its revolutionary images are revealing. Pillars of Creation tells the story of one of the greatest scientific achievements in the history of civilization, a $10 billion instrument with a staggeringly ambitious goal: unlocking the secrets of the cosmos.

What is life? In this penetrating and wide-ranging book, world-renowned physicist and science communicator Paul Davies searches for answers in a field so new and fast-moving that it lacks a name; it is a domain where biology, computing, logic, chemistry, quantum physics, and nanotechnology intersect.

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.

Who are we? How do scientists define Homo sapiens, and how does our species differ from the extinct hominins that came before us? In this accessible account palaeoarchaeologist Paul Pettitt shows how the latest scientific advances, especially in genetics, are revolutionizing our understanding of human evolution. Pettitt reveals the extraordinary story of how our ancestors adapted to unforgiving and relentlessly changing climates, leading to remarkable innovations in art, technology, and society that we are only now beginning to comprehend.

Carl Zimmer investigates one of the biggest questions of all: What is life? The answer seems obvious until you try to seriously answer it. Is the apple sitting on your kitchen counter alive, or is only the apple tree it came from deserving of the word? If we can’t answer that question here on Earth, how will we know when and if we discover alien life on other worlds? The question hangs over some of society’s most charged conflicts - whether a fertilized egg is a living person, for example, and when we ought to declare a person legally dead.

A cataclysmic planetary phenomenon is gathering force deep within the Earth. The magnetic North Pole will eventually trade places with the South Pole. Satellite evidence suggests to some scientists that the move has already begun, but most still think it won't happen for many decades. All agree that it has happened many times before and will happen again. But this time it will be different. It will be a very bad day for modern civilization.

For centuries, humans ignored sound in the “silent world” of the ocean, assuming that what we couldn’t perceive, didn’t exist. But we couldn’t have been more wrong. Marine scientists now have the technology to record and study the complex interplay of the myriad sounds in the sea. Finally, we can trace how sounds travel with the currents, bounce from the seafloor and surface, bend with the temperature and even saltiness; how sounds help marine life survive; and how human noise can transform entire marine ecosystems.

In The Universe in a Box, cosmologist Andrew Pontzen explains how physicists model the universe’s most exotic phenomena, from black holes and colliding galaxies to dark matter and quantum entanglement, enabling them to study the evolution of virtual worlds and to shed new light on our reality.

Gravity is the weakest force in the everyday world, yet it is the strongest force in the universe. It was the first force to be recognized and described, yet it is the least understood. It is a "force" that keeps your feet on the ground, yet no such force actually exists. Gravity, to steal the words of Winston Churchill, is "a riddle, wrapped in a mystery, inside an enigma". And penetrating that enigma promises to answer the biggest questions in science: What is space? What is time? What is the universe? And where did it all come from?

The Strange Order of Things is a pathbreaking investigation into homeostasis, the condition that regulates human physiology within the range that makes possible not only the survival but also the flourishing of life. Antonio Damasio makes clear that we descend biologically, psychologically, and even socially from a long lineage that begins with single living cells; that our minds and cultures are linked by an invisible thread to the ways and means of ancient unicellular life and other primitive life-forms.

Vince Beiser explores the Achilles’ heel of “green power” and digital technology–that manufacturing computers, cell phones, electric cars, and other technologies demand skyrocketing amounts of lithium, copper, cobalt, and other materials. Around the world, businesses and governments are scrambling for new places and new ways to get those metals, at enormous cost to people and the planet. Beiser crisscrossed the world to talk to the people involved and report on the damage this race is inflicting, the ways it could get worse, and how we can minimize the damage.

A nature therapy session for the soul—encounter the benevolence of the living world through 12 essays on the Earth-healing powers of self-compassion and empathy.

As a young girl, Hannah Stowe was raised at the tide’s edge on the Pembrokeshire coast of Wales, falling asleep to the sweep of the lighthouse beam. Now in her midtwenties, working as a marine biologist and sailor, Stowe draws on her professional experiences sailing tens of thousands of miles in the North Sea, North Atlantic, Mediterranean, Celtic Sea, and the Caribbean to explore the human relationship with wild waters. Why is it, she asks, that she and so many others have been drawn to life at sea—and what might the water around us be able to teach us?

After water and air, sand is the natural resource that we consume more than any other - even more than oil. Every concrete building and paved road on Earth, every computer screen and silicon chip, is made from sand. And, incredibly, we're running out of it. The World in a Grain is the compelling true story of the hugely important and diminishing natural resource that grows more essential every day, and of the people who mine it, sell it, build with it - and sometimes, even kill for it.

The Colorado River is an essential resource for a surprisingly large part of the United States, and every gallon that flows down it is owned or claimed by someone. David Owen traces all that water from the Colorado’s headwaters to its parched terminus, once a verdant wetland but now a million-acre desert. He takes listeners on an adventure downriver, along a labyrinth of waterways, reservoirs, power plants, farms, fracking sites, ghost towns, and RV parks, to the spot near the US-Mexico border where the river runs dry.

Understanding how brains produce consciousness is one of the great scientific challenges of our age. Some philosophers argue that consciousness is something "extra", beyond the physical workings of the brain. Others think that if we persist in our standard scientific methods, our questions about consciousness will eventually be answered. And some suggest that the mystery is so deep, it will never be solved.

One of our great contemporary scientists reveals the 10 profound insights that illuminate what everyone should know about the physical world.

For most of us, the only thing we know about flies is that they're annoying, and our usual reaction is to try to kill them. In Super Fly, the myth-busting biologist Jonathan Balcombe shows the order Diptera in all of its diversity, illustrating the essential role that flies play in every ecosystem in the world as pollinators, waste-disposers, predators, and food source; and how flies continue to reshape our understanding of evolution.

Indigenous worldviews, and the knowledge they confer, are critical for human survival and the wellbeing of future generations. Wahinkpe Topa (Four Arrows) and Darcia Narvaez present and discuss 28 powerful excerpted passages from Indigenous leaders, including Mourning Dove, Robin Wall Kimmerer, Winona LaDuke, and Xiuhtezcatl Martinez.
