These days, probiotic yogurt and other "gut-friendly" foods line supermarket shelves. But what's the best way to feed our all-important microbiome - and what is a microbiome, anyway? In this engaging book, science journalist Katherine Harmon Courage investigates these questions, presenting a deep dive into the ancient food traditions and the latest research for maintaining a healthy gut.

First published more than 50 years ago, this award-winning classic brings Rachel Carson's unique vision to a new generation of listeners. The Sense of Wonder is Carson's intimate account of adventures with her young nephew, Roger, as they enjoy walks along the rocky coast of Maine and through dense forests and open fields, observing wildlife, strange plants, moonlight, and storm clouds, and listening to the "living music" of insects in the underbrush.

In The Lives of a Cell, Dr. Lewis Thomas opens up to the listener a universe of knowledge and perception that is perhaps not wholly unfamiliar to the research scientist; but the world he explores is also one of men and women, of complex interrelationships, old ironies, peculiar powers, and intricate languages that give identity to the alienated and direction to the dependent. This remarkable work offers a subtle, bold vision of humankind and the world around us - a sense of what gives life - from a writer who seems to draw grace and strength from the very substance of his subject.

In this Very Short Introduction audiobook, marine biologist Philip Mladenov provides an accessible and up-to-date overview of marine biology, offering a tour of marine life and marine processes that ranges from the unimaginably abundant microscopic organisms that drive the oceans' food web to the apex predators that we exploit for food; from polar ocean ecosystems to tropical coral reefs; and from the luxurious kelp beds of the coastal ocean to deep-ocean hydrothermal vents where life exists without the energy of the sun.

Sociogenomics brings together advances in molecular genetics and traditional social and behavioral science. The key tool is the polygenic index, which allows us to analyze DNA to measure a child's genetic potential. Today, we can estimate a child's adult height, how far they will go in school, and their weight as an adult—all from a cheek swab, finger prick, or vial of saliva. Dalton Conley and other researchers are using this new science to shed light on the ways in which genes shape our world, influencing how each person both creates and responds to the environment around them.

We’ve come a long way. The earliest human had a brain as small as a child’s fist; ours are four times bigger, with spectacular abilities and potential we are only just beginning to understand. This is How the Mind Changed, a seven-million-year journey through our own heads, packed with vivid stories, groundbreaking science, and thrilling surprises. Discover how memory has almost nothing to do with the past.

Until very recently, if you were to ask most doctors, they would tell you there were only two kinds of medicine: the quack kind, and the evidence-based kind. The former is baseless, and the latter based on the best information human effort could buy. Well, Eric Topol isn't most doctors, and he suggests you entertain the notion of a third kind of medicine, one that will make the evidence-based state-of-the-art stuff look scarcely better than an alchemist trying to animate a homunculus in a jar.

Insects surround us. They fuel life on Earth through their roles as pollinators, predators, and prey, but rarely do we consider the outsize influence they have had on our culture and civilization. Their anatomy and habits inform how we live, work, create art, and innovate. From ancient etchings to avant-garde art, from bug-based meals to haute couture, The Insect Epiphany proves that our world would look very different without insects, not just because they are crucial to our ecosystems, but because they have shaped and inspired so many aspects of what makes us human.

Science journalist Sally Adee breaks open the field of bioelectricity—the electric currents that run through our bodies and every living thing—its misunderstood history, and why new discoveries will lead to new ways around antibiotic resistance, cleared arteries, and new ways to combat cancer.

Throughout his distinguished and unconventional career, engineer-turned-molecular-biologist Douglas Axe has been asking the questions that much of the scientific community would rather silence. Now, he presents his conclusions in this brave and pioneering book. Axe argues that the key to understanding our origin is the "design intuition" - the innate belief held by all humans that tasks we would need knowledge to accomplish can be accomplished only by someone who has that knowledge.

The Log from the Sea of Cortez is the exciting day-by-day account of Steinbeck's trip to the Gulf of California with biologist Ed Ricketts. Drawn from the longer Sea of Cortez, it is a wonderful combination of science, philosophy, and high-spirited adventure.

In this glorious celebration of the night, New York Times bestselling nature writer Leigh Ann Henion invites us to leave our well-lit homes, step outside, and embrace the dark as a profoundly beautiful part of the world we inhabit. Because no matter where we live, we are surrounded by animals that rise with the moon, and blooms that reveal themselves as light fades. Henion explores her home region of Appalachia, where she attends a synchronous firefly event in Tennessee, a bat outing in Alabama, and a moth festival in Ohio.

Respected physician Paul Offit tells a fascinating story of modern medicine and pays tribute to one of the greatest lifesaving breakthroughs—vaccinations—and the medical hero responsible for developing nine of the big fourteen vaccines which have saved billions of lives worldwide.

In this myth-busting book, Daniel Lieberman, professor of human evolutionary biology at Harvard University and a pioneering researcher on the evolution of human physical activity, tells the story of how we never evolved to exercise - to do voluntary physical activity for the sake of health. Using his own research and experiences throughout the world, Lieberman recounts without jargon how and why humans evolved to walk, run, dig, and do other necessary and rewarding physical activities while avoiding needless exertion.

We human beings share 98 percent of our genes with chimpanzees. Yet humans are the dominant species on the planet - having founded civilizations and religions, developed intricate and diverse forms of communication, learned science, built cities, and created breathtaking works of art - while chimps remain animals concerned primarily with the basic necessities of survival. What is it about that two percent difference in DNA that has created such a divergence between evolutionary cousins?

At every moment, within our bodies and all around us, trillions of microscopic combatants are waging a war that shapes our health and life on Earth. Countless times per second, viruses known as phages attack and destroy bacteria while leaving all other life forms, including us, unscathed. Vastly outnumbering the viruses that do us harm, phages power ecosystems, drive evolutionary innovation, and harbor a remarkable capacity to heal life-threatening infections when conventional antibiotics fail. Yet most of us have never heard of them, thinking of viruses only as enemies to be feared.

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?

Life is the most extraordinary phenomenon in the known universe; but how does it work? Even in this age of cloning and synthetic biology, the remarkable truth remains: nobody has ever made anything living entirely out of dead material. Life remains the only way to make life. Are we missing a vital ingredient in its creation? Like Richard Dawkins' The Selfish Gene, which provided a new perspective on how evolution works, Life on the Edge alters our understanding of life's dynamics.

Walter Tschinkel has spent much of his career investigating the hidden subterranean realm of ant nests. This book takes you inside an unseen world where thousands of ants build intricate homes in the soil beneath our feet. Tschinkel describes the ingenious methods he has devised to study ant nests, showing how he fills a nest with plaster, molten metal, or wax and painstakingly excavates the cast.
