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.

The landscape of cancer treatment and prevention is a vastly different place than it was even a decade ago. Thanks to a relatively new focus on molecular medicine, researchers are gaining a deeper understanding of the mechanisms involved in the disease, poising them on the brink of huge breakthroughs. What Science Knows About Cancer reports from the front lines of the war on cancer with a clear and scientifically precise - yet thoroughly accessible - guide to how the disease develops, thrives, and can potentially be conquered.

Half of all species could disappear by the end of the century, and scientists now concede that most of America’s endangered animals will survive only if conservationists keep rigging the world around them in their favor. So Jon Mooallem ventures into the field, often taking his daughter with him, to move beyond childlike fascination and make those creatures feel more real. Wild Ones is a tour through our environmental moment and the eccentric cultural history of people and wild animals in America that inflects it.

In what he says is the most important piece of environmental writing in his long and award-winning career, Mark Kurlansky, best-selling author of Salt and Cod, The Big Oyster, 1968, and Milk, among many others, employs his signature multi-century storytelling and compelling attention to detail to chronicle the harrowing yet awe-inspiring life cycle of salmon.

Until recently, microglia were thought to be merely the brain’s housekeepers, helpfully removing damaged cells. But a recent groundbreaking discovery revealed them to be capable of terrifying Jekyll and Hyde behavior. When triggered - and anything that stirs up the immune system in the body can activate microglia - they can morph into destroyers, impacting a wide range of issues from memory problems and anxiety to depression and Alzheimer’s. Under the right circumstances, however, microglia can be coaxed back into being angelic healers.

Acclaimed scientist Hope Jahren has built three laboratories in which she's studied trees, flowers, seeds, and soil. Her first book might have been a revelatory treatise on plant life. Lab Girl is that, but it is also so much more. Because in it, Jahren also shares with us her inspiring life story, in prose that takes your breath away.

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.

Biologist Rob Dunn reveals the crucial influence that other species have upon our health, our well-being, and our world in The Wild Life of Our Bodies - a tour through the hidden truths of nature and codependence. Dunn illuminates the nuanced relationships that exist between homo sapiens and other species, relationships that underpin humanity's ability to thrive and prosper in every circumstance. Fans of Michael Pollan's The Omnivore's Dilemma will be enthralled by Dunn's powerful, lucid exploration of the role that humankind plays within the greater web of life on Earth.

The existence of free will - our ability to choose between one course of action and another, to determine our own destiny - is a foundation stone of Western society, dictating our notions of fairness and justice, punishment and reward, our very identity as individuals and humans. But as world-renowned scientist Robert Sapolsky shows, there is not a shred of evidence to suggest that free will exists, even while everything in our biology leads us to believe that it does.

Despite advances in health care, infectious microbes continue to be a formidable adversary to scientists and doctors. Vaccines and antibiotics, the mainstays of modern medicine, have not been able to conquer infectious microbes because of their amazing ability to adapt, evolve, and spread to new places. Terrorism aside, one of the greatest dangers from infectious disease we face today is from a massive outbreak of drug-resistant microbes.

Sweating may be one of our weirdest biological functions, but it’s also one of our most vital and least understood. In The Joy of Sweat, Sarah Everts delves into its role in the body - and in human history. Everts’ entertaining investigation takes listeners around the world - from Moscow, where she participates in a dating event in which people sniff sweat in search of love, to New Jersey, where companies hire trained armpit sniffers to assess the efficacy of their anti-sweat products. Along the way, Everts traces humanity’s long quest to control sweat.

What defines who we are? For decades, the answer has seemed obvious: our genes, the "blueprint of life." In The Master Builder, biologist Alfonso Martinez Arias argues we've been missing the bigger picture. It's not our genes that define who we are, but our cells.

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.

Don and Mimi Galvin seemed to be living the American dream. After World War II, Don's work with the Air Force brought them to Colorado, where their 12 children perfectly spanned the baby boom: the oldest born in 1945, the youngest in 1965. In those years, there was an established script for a family like the Galvins—aspiration, hard work, upward mobility, domestic harmony. But behind the scenes was a different story: psychological breakdown, sudden shocking violence, hidden abuse. By the mid-1970s, six of the 10 Galvin boys, one after another, were diagnosed as schizophrenic.

Why do people believe bunk? And what causes them to embrace such pseudoscientific beliefs and practices? Noted skeptic Massimo Pigliucci sets out to separate the fact from the fantasy in this entertaining exploration of the nature of science, the borderlands of fringe science, and - borrowing a famous phrase from philosopher Jeremy Bentham - the nonsense on stilts.

Seashells, stretching from the deep past into the present day, are touchstones leading into fascinating realms of the natural world and cutting-edge science. In Spirals in Time, marine biologist Helen Scales shows how seashells have been sculpted by the fundamental rules of mathematics and evolution; how they gave us color, gems, food, and new medicines. Spirals in Time shows why nature matters and reveals the hidden wonders that you can hold in the palm of your hand.

The Ancestor's Tale is a pilgrimage back through time - a journey on which we meet up with fellow pilgrims as we and they converge on our common ancestors. Chimpanzees join us at about six million years in the past, gorillas at seven million years, orangutans at 14 million years, as we stride on together, a growing band. The journey provides the setting for a collection of some 40 tales.

This pathbreaking book explores how life can begin, taking us from cosmic clouds of stardust, to volcanoes on Earth, to the modern chemistry laboratory. Seeking to understand life's connection to the stars, David Deamer introduces astrobiology, a new scientific discipline that studies the origin and evolution of life on Earth and relates it to the birth and death of stars, planet formation, interfaces between minerals, water, and atmosphere, and the physics and chemistry of carbon compounds.

Cutting-edge techniques across biology, chemistry, physics, and geology have transformed our understanding of the deep past, including the discovery of a previously unknown mass extinction. This compelling evidence, revealing a series of environmental crises resulting in the near collapse of life on Earth, illuminates our current dilemmas in exquisite detail.

All of us would like to live longer, or to slow the debilitating effects of age. In How We Age, Coleen Murphy shows how recent research on longevity and aging may be bringing us closer to this goal. Murphy, a leading scholar of aging, explains that the study of model systems, particularly simple invertebrate animals, combined with breakthroughs in genomic methods, have allowed scientists to probe the molecular mechanisms of longevity and aging.
