Psychologists study which cognitive operations underpin a given conscious perception. Neuroscientists track the neural correlates of consciousness in the brain, the organ of the mind. But why the brain and not, say, the liver? How can the brain, three pounds of highly excitable matter, a piece of furniture in the universe, subject to the same laws of physics as any other piece, give rise to subjective experience? Koch argues that what is needed to answer these questions is a quantitative theory that starts with experience and proceeds to the brain.

Carl Zimmer investigates one of the biggest questions of all: What is life? The answer seems obvious until you try to seriously answer it. Is the apple sitting on your kitchen counter alive, or is only the apple tree it came from deserving of the word? If we can’t answer that question here on Earth, how will we know when and if we discover alien life on other worlds? The question hangs over some of society’s most charged conflicts - whether a fertilized egg is a living person, for example, and when we ought to declare a person legally dead.

Offering innovative ideas for protecting coastlines and cleaning the toxic seas, Scales insists we need more ethical and sustainable fisheries and must prevent the other existential threat of deep-sea mining, which could significantly alter life on earth. Inspiring us all to maintain a sense of awe and wonder at the majesty beneath the waves, she urges us to fight for the better future that still exists for the Anthropocene ocean.

Humans are the most inquisitive, emotional, imaginative, aggressive, and baffling animals on the planet. But how well do we really know ourselves? How to Be Animal rewrites the remarkable human story and argues that at the heart of our psychology is a profound struggle with being animal.

Understanding someone who belongs to another species can be transformative. No one knows this better than author, naturalist, and adventurer Sy Montgomery. To research her books, Sy has traveled the world and encountered some of the planet's rarest and most beautiful animals. From tarantulas to tigers, Sy's life continually intersects with and is informed by the creatures she meets. This restorative memoir reflects on the personalities and quirks of 13 animals - Sy's friends - and the truths revealed by their grace.

Once relegated to the fringes of society, transhumanism (the use of technology to enhance human intellectual and physical capability) is now poised to enter our cultural mainstream. It has found adherents in Silicon Valley billionaires Ray Kurzweil and Peter Diamandis. Google has entered the picture, establishing a bio-tech subsidiary aimed at solving the problem of aging. In To Be a Machine, journalist Mark O'Connell takes a headlong dive into this burgeoning movement.

What is it like to be a dog? A bat? Or a dolphin? To find out, neuroscientist Gregory Berns and his team began with a radical step: they taught dogs to go into an MRI scanner - completely awake. They discovered what makes dogs individuals with varying capacities for self-control, different value systems, and a complex understanding of human speech. And dogs were just the beginning. In What It's Like to Be a Dog, Berns explores the fascinating inner lives of wild animals from dolphins and sea lions to the extinct Tasmanian tiger.

In this startling study of human emotion, Dacher Keltner investigates an unanswered question of human evolution: If humans are hardwired to lead lives that are "nasty, brutish, and short," why have we evolved with positive emotions like gratitude, amusement, awe, and compassion that promote ethical action and cooperative societies? Born to Be Good takes us on a journey through scientific discovery, personal narrative, and Eastern philosophy.

This practical and groundbreaking guide reveals seven paths to fighting the effects of stress - to strengthen our natural defenses so that our minds remain sharp, and our bodies resilient, no matter what life throws at us.

"Consciousness is what makes the mind-body problem really intractable." So begins Thomas Nagel's classic 1974 essay "What is it Like to be a Bat?" Nagel's essay initiated the now widespread attention to consciousness as a central problem for philosophy, psychology, and neuroscience; it also influenced the recognition of the consciousness of nonhuman creatures as an important subject of study.

In What It's Like to Be a Bird, David Sibley answers the most frequently asked questions about the birds we see most often. This special brand-new audio edition is geared as much to nonbirders as it is to the out-and-out obsessed, covering more than 200 species. While its focus is on familiar backyard birds—blue jays, nuthatches, chickadees—it also examines certain species that can be fairly easily observed, such as the seashore-dwelling Atlantic puffin.

Where will we live? How will we get around? What will we look like? These are just some of the questions bestselling author and popular science broadcaster Jay Ingram answers in this exciting examination of the science and technologies that will affect every aspect of human life. In this book, Ingram explores the future of our technological civilization. He reports on cutting-edge research in organ and limb regeneration, advances in prosthetics, the merging of the human and the synthetic, and gene editing.

From eye-witness accounts of elephants apparently mourning the death of family members to an experiment that showed that hungry rhesus monkeys would not take food if doing so gave another monkey an electric shock, there is much evidence of animals displaying what seem to be moral feelings. But despite such suggestive evidence, philosophers steadfastly deny that animals can act morally, and for reasons that virtually everyone has found convincing.

When Karin enters a high-ranked university to start her PhD she is brimming with hope and positively overflowing with grit determination to prove she is worthy. After all, she knows that only the extraordinarily learned and the astonishingly intelligent ever hold chairs and professorships. She knows researchers are idealists yearning to enrich the stock of human knowledge. She knows university is the apotheosis of civilised culture... She knows very little.

How to Be Animal tells a remarkable story of what it means to be human and argues that at the heart of our existence is a profound struggle with being animal. We possess a psychology that seeks separation between humanity and the rest of nature, and we have invented grand ideologies to magnify this. As well as piecing together the mystery of how this mindset evolved, Challenger's book examines the wide-reaching ways in which it affects our lives, from our politics to the way we distance ourselves from other species.

You're invited to discover the wonder and drama of the history of the cosmos. Follow the journey of one proton who comes into existence at the beginning of creation and makes it all the way through history to today. By becoming a part of atoms and molecules that turn up at some of the universe's most important moments, our friend Proton witnesses emerging galaxies, the origin of life, evolution, the first human beings, the birth and life of Jesus, the beginnings of the Christian church, all the way up to the present day. Through it all, the plans of the Creator continue to unfold.

What is it like to be a swift, flying at over one hundred kilometres an hour? Or a kiwi, plodding flightlessly among the humid undergrowth in the pitch dark of a New Zealand night? And what is going on inside the head of a nightingale as it sings, and how does its brain improvise? Bird Sense addresses questions like these and many more, by describing the senses of birds that enable them to interpret their environment and to interact with each other.

If you have a taste for honey or an adventurous side, maybe you have thought of becoming a beekeeper. What would you really be in for, though?

Anyone can do it, as long as they know to be prepared. You can't just wake up one day and decided to be a beekeeper and start immediately, without knowing what you are doing.

The most valuable investment any society makes is in its children, the next generation. The more we learn about the fetus the better we are able to understand the problems and abnormalities that can occur during development. Dr. Peter Nathanielsz, the first to demonstrate that the fetal brain delivers the signals that start the process of birth, reviews the recent explosion of information on fetal development during the second half of pregnancy.
