Consciousness is the most fascinating but tantalizingly difficult topic in biology. Although many people now believe that mammals, birds, and possibly all vertebrates are conscious, there are also claims that many other animals such as crabs and insects may be conscious too. Such claims, if true, would have major implications for what we eat, how we control pests, and for our relationship with the animal world. Now, more than ever, it is important to question the evidence and ask: what do we really know about animal consciousness?

As a tutor of Biology of about 20 years experience I quite often came across students who were struggling with the basics. Most often the subject of the basic biological molecules; proteins, carbohydrates and lipids, was causing them some confusion. Admittedly, for biology students who don't study chemistry, this subject can be a challenge. So what I have done in this book is give a summary of the most important points about these molecule groups in the easily understandable format, of a series of questions and answers. I have also included a chapter of key words, that I explain, before the...

A compelling investigation into one of our most coveted and cherished ideals, and the efforts of modern science to penetrate the mysterious nature of this timeless virtue. We all recognize wisdom, but defining it is more elusive. In this fascinating journey from philosophy to science, Stephen S. Hall gives us a dramatic history of wisdom, from its sudden emergence in four different locations (Greece, China, Israel, and India) in the fifth century B.C. to its modern manifestations.

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.

Para cada célula humana em nosso organismo, há outras nove impostoras, pegando carona. Você não é formado apenas de carne e osso, sangue e músculo, mas também de bactérias e fungos. Não é um indivíduo, mas uma colônia–um ecossistema. Somos apenas 10% humanos. Até pouco tempo atrás, os micróbios eram vistos como invasores, inimigos, parasitas. Estávamos decididos a exterminá-los. Mas a ciência vem revelando uma história bem diferente: os micro-organismos comandam nosso corpo e evoluíram numa relação de estreita simbiose com os humanos–e é impossível ser saudável sem eles.

Understanding why we age and how to prevent age-related physical and mental decline can help us to live in the moment and enjoy our health at any age. In this audiobook, we explore the latest thinking in why we age, strategies to help maintain good health, as well as research into the limits of human longevity.

What is our immune system, and how does it work? A vast array of cells, proteins and chemicals spring into action whenever our bodies are damaged, but immunity is not something you can see, touch, or feel. It can fight off malicious bacteria and viruses, locate cancerous growths, and even rewire our brains—but sometimes our own tissues can get caught in its crossfire, with catastrophic consequences. Humans may be the most disease-ridden animals on the planet. Professor John Trowsdale shows how the immune system protects us, and how our bodies invest huge resources to keep it running.

In this sweeping history of more than 3,000 years, beginning with ancient Egypt, scientist Marcus Byrne and writer Helen Lunn capture the diversity of dung beetles and their unique behavior patterns. Dung beetles' fortunes have followed the shifts from a world dominated by a religion that symbolically incorporated them into some of its key concepts of rebirth, to a world in which science has largely separated itself from religion and alchemy.  

When the woman he loved was diagnosed with a metastatic cancer, science writer George Johnson embarked on a journey to learn everything he could about the disease and the people who dedicate their lives to understanding and combating it. What he discovered is a revolution under way—an...

Our world is infinitely richer than previously guessed, yet it is so ravaged by human activity that half its species could be gone by the end of the century. In this dazzlingly intelligent and ultimately hopeful work, biologist E.O. Wilson describes what treasures of the natural world we are about to lose forever—in many cases animals, insects, and plants we have only just discovered—and what we can do to save them. Wilson explores the ethical and religious bases of the conservation movement and deflates the myth that environmental policy is antithetical to economic growth.

Imagine knowing years in advance whether you are likely to get cancer, or having a personalized understanding of your individual genes, organs, and cells. Imagine being able to monitor your body's well-being, or have a diet tailored to your microbiome. The Secret Body reveals how these and other stunning breakthroughs and technologies are transforming our understanding of how the human body works, what it is capable of, how to protect it from disease, and how we might manipulate it in the future.

The award-winning and surprisingly hopeful story of one woman's search for resiliency in a warming world Several years ago, ecologist Lauren E. Oakes set out from California for Alaska's old-growth forests to hunt for a dying tree: the yellow-cedar. With climate change as the culprit, the death...

Important and provocative, The Undead examines why even with the tools of advanced technology, what we think of as life and death, consciousness and nonconsciousness, is not exactly clear - and how this problem has been further complicated by the business of organ harvesting.

Sea turtles are the ancient mariners of our planet. Long before human sailors braved the open seas, these gentle reptiles were already navigating the vast blue expanse with a precision that continues to astound scientists today. For more than 100 million years, sea turtles have survived continental shifts, ice ages, and mass extinctions. They are living fossils whose epic migrations link the distant past with our uncertain present, journeys written in sand, salt, and instinct.

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.
