Everyone has heard the story of DNA as the story of Watson, Crick, and Rosalind Franklin, but knowing the structure of DNA was only part of a greater struggle to understand life's secrets. Life's Greatest Secret is the story of the discovery and cracking of the genetic code, the thing that ultimately enables a spiraling molecule to give rise to the life that exists all around us. This great scientific breakthrough has had far-reaching consequences for how we understand ourselves and our place in the natural world.

In this tour of the animal kingdom, evolutionary biologist Lee Alan Dugatkin reveals a new field of study, uncovering social networks that existed long before the dawn of human social media. He accessibly describes the latest findings from animal behavior, evolution, computer science, psychology, anthropology, genetics, and neurobiology, and incorporates interviews and insights from researchers he finds swimming with manta rays, avoiding pigeon poop, and stopping monkeys from stealing iPads.

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.

More than 10,000 years ago spectacularly large mammals roamed the pampas and jungles of South America. This book tells the story of these great beasts during and just after the Pleistocene, the geological epoch marked by the great ice ages. Megafauna describes the history and way of life of these animals, their comings and goings, and what befell them at the beginning of the modern era and the arrival of humans.

For many of us, the great scientific discoveries of the modern age—the Big Bang, evolution, quantum physics, relativity—point to an existence that is bleak, devoid of meaning, pointless. But in The Sacred Depths of Nature, eminent biologist Ursula Goodenough shows us that the scientific world view need not be a source of despair. Indeed, it can be a wellspring of solace and hope. This volume reconciles the modern scientific understanding of reality with our timeless spiritual yearnings for reverence and continuity.

Among scientists who write, no one illuminates as well as Stephen Jay Gould does the wonderful workings of the natural world. Now in a new volume of collected essays—his sixth since Ever Since Darwin—Gould speaks of the importance of unbroken connections within our own lives and to our ancestral generations. Along with way, he opens to us the mysteries of fish tails, frog calls, and other matters, and shows once and for all why we must take notice when a seemingly insignificant creature is threatened, like the land snail Partula from Moorea, whose extinction he movingly relates.

This book looks at the weird and wonderful world of parasites, the most abundant form of life on Earth. Parasites come in all forms and sizes and inhabit every free-living organism. Parasitism is now, and always has been, a way to survive under changing environmental conditions. From arctic oceans to tropical forests, Scott Gardner, Judy Diamond, and Gabor Racz investigate how parasites survive and evolve, and how they influence and provide stability to ecosystems.

In Life Between the Tides, Adam Nicolson investigates one of the most revelatory habitats on earth. Under his microscope, we see a prawn's head become a medieval helmet and a group of "winkles" transform into a Dickensian social scene, with mollusks munching on Stilton and glancing at their pocket watches. Or, rather, is a winkle more like Achilles, an ancient hero, throwing himself toward death for the sake of glory? For Nicolson, the world of the rockpools is infinite and as intricate as our own.

Morange covers everything from the first cell theory to the origins of the concept of ecosystems, and offers perspectives on areas that are often neglected by historians of biology, such as ecology, ethology, and plant biology. He highlights the contributions of technology, the important role of hypothesis and experimentation, and the cultural contexts in which some of the most breathtaking discoveries in biology were made. Unrivaled in scope and written by a world-renowned historian of science, A History of Biology is an ideal introduction for students and experts alike.

It was September 18, 2001. In the early morning darkness, a lone figure dropped several letters into a mailbox. Seventeen days later, a Florida journalist died of inhalational anthrax. It killed five people, disfigured at least 18 more, and launched the largest investigation in the FBI's history. These anthrax attacks marked the first time a sophisticated biological weapon was released in the United States. Recounting the Anthrax Attacks explores the origins of the innovative forensics used in this case, while also explaining their historical context.

For much of recorded history, people considered the heart to be the most important organ in the body. In cultures around the world, the heart—not the brain—was believed to be the location of intelligence, memory, emotion, and the soul. Over time, views on the purpose of the heart have transformed. Modern medicine and science dismissed what was once the king of the organs as a mere blood pump subservient to the brain, yet the heart remains a potent symbol of love and health and an important part of our cultural iconography.

Susanne Schötz is hard at work on breaking the cat code. She is a professor at Lund University in Sweden, where a long-standing research program is proving that cats do actually use vocal communication-with each other and with their human caretakers. Understanding the vocal strategies used in human-cat communication will have profound implications for how we communicate with our pets and has the potential to improve the relationship between animals and humans within several fields, including animal therapy, veterinary medicine, and animal sheltering.

Every cow just wants to be happy. Every chicken just wants to be free. Every bear, dog, or mouse experiences sorrow and feels pain as intensely as any of us humans do. In a compelling appeal to reason and human kindness, Matthieu Ricard here takes the arguments from his best sellers Altruism and Happiness to their logical conclusion: Compassion toward all beings, including our fellow animals, is a moral obligation and the direction toward which any enlightened society must aspire.

In Methusaleh's Zoo, Steven Austad tells the stories of some extraordinary animals, considering why, for example, animal species that fly live longer than earthbound species and why animals found in the ocean live longest of all. Austad—the leading authority on longevity in animals—argues that the best way we will learn from these long-lived animals is by studying them in the wild.

The Internet and smartphone are just the latest in a 250-year-long cycle of disruption that has continuously changed the way we live, the way we work, and the way we interact. The coming Augmented Age, however, promises a level of disruption, behavioral shifts, and changes that are unparalleled. While consumers today are camping outside of an Apple store waiting to be one of the first to score a new Apple Watch or iPhone, the next generation of wearables will be able to predict if we're likely to have a heart attack and recommend a course of action.

With rapid advances in genomic technologies, genetic testing has become a key part of both clinical practice and research. Scientists are constantly discovering more about how genetics plays a role in health and disease, and healthcare providers are using this information to more accurately identify their patients' particular medical needs. Genetic information is also increasingly being used for a wide range of non-clinical purposes, such as exploring one's ancestry.

In December 1929, in a cave near Peking, a group of anthropologists and archaeologists that included a young French Jesuit priest named Pierre Teilhard de Chardin uncovered a prehuman skull. The find quickly became known around the world as Peking Man and was acclaimed as the missing link between erect hunting apes and our Cro-Magnon ancestors. It also became a provocative piece of evidence in the roiling debate over creationism versus evolution.

For Irwin Shapiro, science starts with questions. This book provides a broad and entertaining survey of major scientific discoveries that have changed our views of nature and, in turn, spawned further questions. Shapiro, an award-winning scientist and beloved teacher, separates his inquiry into three parts: looking up at the universe; looking down at the earth and its fossils; and looking in at the story of life. His framework encourages listeners to view science as a detective story—to observe and question nature and natural phenomena, and to base all conclusions on scientific evidence.

Collections of preserved plant specimens, known as herbaria, have existed for nearly five centuries. These pressed and labeled plants have been essential resources for scientists, allowing them to describe and differentiate species and to document and research plant changes and biodiversity over time—including changes related to climate. Maura C. Flannery tells the history of herbaria, from the earliest collections belonging to such advocates of the technique as sixteenth-century botanist Luca Ghini, to the collections of poets, politicians, and painters, and to the digitization today.

For billions of years, microbes have produced and consumed greenhouse gases that regulate global temperature and in turn other aspects of our climate. The balance of these gases maintains Earth's habitability. Methane, a greenhouse gas produced only by microbes, may have kept Earth out of a deep freeze billions of years ago. Likewise, variations in carbon dioxide, another greenhouse gas released by microbes and other organisms, help to explain the comings and goings of ice ages over the last million years. Now we face a human-made climate crisis with drastic consequences.
