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.

Why Animals Talk is an exhilarating journey through the untamed world of animal communication. Following his international bestseller, The Zoologist’s Guide to the Galaxy, acclaimed zoologist Arik Kershenbaum draws on extensive original research to reveal how many of the animal kingdom’s most seemingly confusing or untranslatable signals are in fact logical and consistent—and not that different from our own.

Homo Deus explores the projects, dreams, and nightmares that will shape the 21st century - from overcoming death to creating artificial life. It asks the fundamental questions: Where do we go from here? And how will we protect this fragile world from our own destructive powers? This is the next stage of evolution. This is Homo Deus.

In this classic volume, Peter Matthiessen exquisitely combines nature and travel writing to bring East Africa to vivid life. He skillfully and magically portrays the sights, scenes, and people he observed firsthand in several trips over the course of a dozen years: the daily lives of herdsmen and hunter-gatherers; the drama of the predator kills; the hundreds of exotic animals; the breathtaking landscapes; the area's turbulent natural, political, and social histories; and more.

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.

Our ability to think about the future is one of the most powerful tools at our disposal. In The Invention of Tomorrow, cognitive scientists Thomas Suddendorf, Jonathan Redshaw, and Adam Bulley argue that its emergence transformed humans from unremarkable primates to creatures that hold the destiny of the planet in their hands. Drawing on their own cutting-edge research, the authors break down the science of foresight, showing us where it comes from, how it works, and how it made our world.

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 mid-1970s, scientists began using DNA sequences to reexamine the history of all life. Perhaps the most startling discovery to come out of this new field is horizontal gene transfer (HGT), or the movement of genes across species lines. For instance, we now know that roughly eight percent of the human genome arrived not through traditional inheritance from directly ancestral forms, but sideways by viral infection - a type of HGT. In The Tangled Tree David Quammen chronicles these discoveries through the lives of the researchers who made them.

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 A Human History of Emotion, Richard Firth-Godbehere takes listeners on a fascinating and wide ranging tour of the central and often under-appreciated role emotions have played in human societies around the world and throughout history — from Ancient Greece to Gambia, Japan, the Ottoman Empire, the United States, and beyond.

Scratch beneath the surface of a coffee bean, a red pepper flake, a poppy seed, a mold spore, a foxglove leaf, a magic-mushroom cap, a marijuana bud, or an apple seed, and we find a bevy of strange chemicals. We use these to greet our days (caffeine), titillate our tongues (capsaicin), recover from surgery (opioids), cure infections (penicillin), mend our hearts (digoxin), bend our minds (psilocybin), calm our nerves (CBD), and even kill our enemies (cyanide). But why do plants and fungi produce such chemicals? And how did we come to use and abuse some of them?

In his provocative new book, evolutionary biologist Jerry A. Coyne lays out in clear, dispassionate detail why the toolkit of science, based on reason and empirical study, is reliable, while that of religion - including faith, dogma, and revelation - leads to incorrect, untestable, or conflicting conclusions.

A fascinating investigation of the origin of humans based on incredible new discoveries and advanced scientific technology.

In Hurricane Lizards and Plastic Squid, biologist Thor Hanson tells the remarkable story of how plants and animals are responding to climate change: adjusting, evolving, and sometimes dying out. Anole lizards have grown larger toe pads, to grip more tightly in frequent hurricanes. Warm waters cause the development of Humboldt squid to alter so dramatically that fishermen mistake them for different species. Brown pelicans move north, and long-spined sea urchins south, to find cooler homes.

Over more than 25 years of teaching and research, Christine Desdemaines-Hugon has become an unrivaled expert in the cave art and artists of the Dordogne region. In Stepping-Stones she combines her expertise in both art and archaeology to convey an intimate understanding of the "cave experience." Her keen insights communicate not only the incomparable artistic value of these works but also the near-spiritual impact of viewing them for oneself.

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.

It is now known that we live in a galaxy with more planets than stars. The Milky Way alone encompasses 30 trillion potential home planets. Scientists Trefil and Summers bring listeners on a marvelous experimental voyage through the possibilities of life-unlike anything we have experienced so far - that could exist on planets outside our own solar system.

Can there be freedom and free will in a deterministic world? Renowned philosopher Daniel Dennett emphatically answers "yes!" Using an array of provocative formulations, Dennett sets out to show how we alone among the animals have evolved minds that give us free will and morality. Weaving a richly detailed narrative, Dennett explains in a series of strikingly original arguments - drawing upon evolutionary biology, cognitive neuroscience, economics, and philosophy - that far from being an enemy of traditional explorations of freedom, morality, and meaning, the evolutionary perspective can be an indispensable ally.

Where did I come from? Why do I have two arms but just one head? How is my left leg the same size as my right one? Why are the fingerprints of identical twins not identical? How did my brain learn to learn? Why must I die? Questions like these remain biology's deepest and most ancient challenges. They force us to confront a fundamental biological problem: How can something as large and complex as a human body organize itself from the simplicity of a fertilized egg?

Scientists are confident that life exists elsewhere in the universe. Yet rather than taking a realistic approach to what aliens might be like, we imagine that life on other planets is the stuff of science fiction. The time has come to abandon our fantasies of space invaders and movie monsters and place our expectations on solid scientific footing. But short of alien's landing in New York City, how do we know what they are like?
