In this classic work that continues to inspire its many fans, James Lovelock deftly explains his idea that life on Earth functions as a single organism. Written for the non-scientist, Gaia is a journey through time and space in search of evidence with which to support a new and radically different model of our planet. In contrast to conventional belief that living matter is passive in the face of threats to its existence, the book explores the hypothesis that the Earth's living matter - air, ocean, and land surfaces - forms a complex system that has the capacity to keep the Earth a fit place for life.

The Blind Watchmaker, knowledgably narrated by author Richard Dawkins, is as prescient and timely a book as ever. The watchmaker belongs to the 18th-century theologian William Paley, who argued that just as a watch is too complicated and functional to have sprung into existence by accident, so too must all living things, with their far greater complexity, be purposefully designed. Charles Darwin's brilliant discovery challenged the creationist arguments; but only Richard Dawkins could have written this elegant riposte.

A revelation for Moby-Dick devotees and neophytes alike, Ahab's Rolling Sea is a chronological journey through the natural history of Melville's novel. From white whales to whale intelligence, giant squids, barnacles, albatross, and sharks, Richard J. King examines what Melville knew from his own experiences and the sources available to a reader in the mid-1800s, exploring how and why Melville might have twisted what was known to serve his fiction.

While plenty of entertaining books have been written about the history of alcohol and other intoxicants, none have offered a comprehensive, convincing answer to the basic question of why humans want to get high in the first place. Drunk elegantly cuts through the tangle of urban legends and anecdotal impressions that surround our notions of intoxication to provide the first rigorous, scientifically grounded explanation for our love of alcohol.

Humans are a puzzling species. On the one hand, we struggle to survive on our own in the wild, often failing to overcome even basic challenges, like obtaining food, building shelters, or avoiding predators. On the other hand, human groups have produced ingenious technologies, sophisticated languages, and complex institutions that have permitted us to successfully expand into a vast range of diverse environments. What has enabled us to dominate the globe, more than any other species, while remaining virtually helpless as lone individuals?

Every Wednesday, Gretchen Reynolds singlehandedly influences how millions of Americans work out. In her Phys Ed column for The New York Times, she debunks myths, spurs conversation, and creates arguments among her readers by questioning widely held beliefs about exercise. Expanding upon her popular columns, Reynolds tackles the questions we all have and (sometimes) ask about exercise.

Perhaps the most influential science book ever written, On the Origin of Species has continued to fascinate for more than a century after its initial publication. Its controversial theory that populations evolve and adapt through a process known as natural selection led to heated scientific, philosophical, and religious debate, revolutionizing every discipline in its wake. With its clear, concise, and surprisingly enjoyable prose, On the Origin of Species is both captivating and edifying.

Fifty years ago, a young astronomer named Frank Drake pointed a radio telescope at nearby stars in the hope of picking up a signal from an alien civilization. Thus began one of the boldest scientific projects in history, the Search for Extraterrestrial Intelligence (SETI). But after a half century of scanning the skies, astronomers have little to report but an eerie silence---eerie because many scientists are convinced that the universe is teeming with life.

The cells in our bodies consist of molecules, made up of the same carbon, oxygen, and hydrogen atoms found in air and rocks. But molecules, such as water and sugar, are not alive. So how do our cells - assemblies of otherwise "dead" molecules - come to life, and together constitute a living being? In Life’s Ratchet, physicist Peter M. Hoffmann locates the answer to this age-old question at the nanoscale.

Informed by cutting-edge scientific research and sparkling with memorable characters - from the modern druids who worship at Stonehenge each solstice to the Amish farmers who may have the right idea about healthy sleep patterns - Linda Geddes’s Chasing the Sun analyzes all aspects of our relationship to the sun. The fascinating stories, innovative science, and unique perspectives in this book make it clear that the ancients were right to put the sun at the center of our world and that it is crucial that we remember this bond as we shape our lives today.

Breathless is story of SARs-CoV-2 and its fierce journey through the human population, as seen by the scientists who study its origin, its ever-changing nature, and its capacity to kill us. David Quammen expertly shows how strange new viruses emerge from animals into humans as we disrupt wild ecosystems and how those viruses adapt to their human hosts, sometimes causing global catastrophe. He explains why this coronavirus will probably be a “forever virus,” destined to circulate among humans and bedevil us endlessly, in one variant form or another.

It seems like every time a new mother turns on her computer, radio, or television she is greeted with news of yet another scientific study about infancy. Ignoring good information isn't the right course, but just how does one tell the difference between solid studies, preliminary results, and snake oil? In this friendly guide through the science of infancy, Science of Mom blogger and PhD scientist Alice Callahan explains how nonscientist mothers can learn the difference between hype and evidence.

Hay fever. Peanut allergies. Eczema. Either you have an allergy or you know someone who does. Billions of people worldwide—an estimated 30 to 40 percent of the global population—have some form of allergy. Even more concerning, over the last decade the number of people diagnosed with an allergy has been steadily increasing, placing an ever-growing medical burden on individuals, families, communities, and healthcare systems. Medical anthropologist Theresa MacPhail, herself an allergy sufferer whose father died of a bee sting, set out to understand why.

Seventy years ago, Erwin Schrdinger posed a simple, yet profound, question: What is life?. How could the very existence of such extraordinary chemical systems be understood? This problem has puzzled biologists and physical scientists both before, and ever since. Living things are hugely complex and have unique properties, such as self-maintenance and apparently purposeful behaviour which we do not see in inert matter. So how does chemistry give rise to biology?

In The Equations of Life, biologist Charles S. Cockell makes the forceful argument that the laws of physics narrowly constrain how life can evolve, making evolution's outcomes predictable. If we were to find something very much like a lady bug eating something very much like an aphid on a distant planet, we shouldn't be surprised. The forms of life are guided by a limited set of rules, and, as a result, there is a narrow set of solutions to the challenges of existence.

In this fascinating and thought-provoking book, author Nick Lane brings together the latest research findings in the exciting field of mitochondria research to reveal how our growing understanding of mitochondria is shedding light on how complex life evolved, why sex arose (why don't we just bud?), and why we age and die. This understanding is of fundamental importance, both in understanding how we and all other complex life came to be, but also in order to be able to control our own illnesses, and delay our degeneration and death.

A giant of archaeology, Colin Renfrew has immeasurably improved our understanding of human history. In this passionately argued work, he offers a concise summary of prehistory - human existence that predates the development of written records - while challenging the very definition of prehistory itself.

Evolution is one of the most important processes in life. It not only explains the detailed history of life on earth, but its scope also extends into many aspects of our own contemporary behavior - who we are and how we got to be here, our psychology, our cultures - and greatly impacts modern advancements in medicine and conservation biology. Perhaps its most important claim for science is its ability to provide an overarching framework that integrates the many life sciences into a single unified whole. Yet, evolution has been, and continues to be, regarded with suspicion by many.

If you are at all interested in life on our planet, then you need to know about insects. They are the most successful group of animals ever to have lived on Earth. Making up three quarters of all animal species, insects conquered the planet long ago. They were among the very first animals to appear on land and were the first to take to the air. Their total biomass is at least 10 times that of all humans and our livestock combined.

Perfect for fans of horror and science alike, Rise of the Zombie Bugs offers a chilling yet enlightening look at the hidden world of parasites. It's a must-listen for anyone curious about the true terrors lurking in nature's undergrowth and the unnerving beauty of evolution's darker side.
