Sharks are some of the most fascinating and ecologically important, yet most threatened and misunderstood animals on Earth. More often feared than revered, their role as predators of the deep has earned them a reputation as a major threat to humans. But the truth is that sharks are not a danger to us—they’re in danger from us. In Why Sharks Matter, marine conservation biologist Dr. David Shiffman urges us to overcome our misconceptions and embrace sharks as the imperiled and elegant ocean guardians they really are.

With over 17,000 known diseases affecting humans, and countless poisons, carcinogens and toxins in our environment, it's a miracle that our bodies manage to keep us alive. And that is, of course, if they don't betray us themselves, whether through cancers or autoimmune conditions. Biomedical researcher Professor John Tregoning tells the unlikely story of how, against all odds, we manage to stay alive. Taking an organ-by-organ tour of the human body, Tregoning embarks on his own experimental quest, testing 'life-extending' diets and exercise regimes to separate fact from fad.

From the cup of coffee that jump-starts the day to dangerously addictive drugs, the recreational use of plants with psychoactive properties has a long history among humans. But, as with many things, it turns out that other animals got there first. From parrots to primates, consuming medicinal chemicals is an instinctive behavior that helps countless organisms fight infection and treat disease. But the similarities don't end there: Like us, many creatures also consume substances that have no apparent benefit...except for inducing intoxication.

Ageing - not cancer, not heart disease - is the world’s leading cause of death and suffering. We accept as inevitable that as we get older our bodies and minds begin to deteriorate, and we are increasingly likely to be struck by dementia or disease. Ageing is so deeply ingrained in human experience that we never think to ask: is it necessary?

In PULL, Brennan Spiegel, M.D. presents a groundbreaking exploration of how gravity influences conditions of body and mind that have puzzled medical professionals for centuries. Starting with a simple observation at a family dinner and culminating in a new approach to gravity-based health and wellness, PULL is a captivating journey through the human body’s inner struggle to keep us upright and healthy.

Few people know much about stem cell research beyond the ethical questions raised by using embryos. But in the last decade, stem cell research has made huge advances toward eliminating some of our most intractable diseases. Now this sweeping and accessible book introduces us to this cutting-edge science, which will revolutionize medicine and change the way we think about and treat disease.

Suddenly, research findings require a paradigm shift in our view of the microbial world. The Human Microbiome Project at the National Institutes of Health is well under way, and unprecedented scientific technology now allows the censusing of trillions of microbes inside and on our bodies as well as in the places where we live, work, and play. This intriguing, up-to-the-minute book for scientists and nonscientists alike explains what researchers are discovering about the microbe world and what the implications are for modern science and medicine.

Survival of the Beautiful is a revolutionary new examination of the interplay of beauty, art, and culture in evolution. Taking inspiration from Darwin's observation that animals have a natural aesthetic sense, philosopher and musician David Rothenberg probes why animals, humans included, have innate appreciation for beauty - and why nature is, indeed, beautiful.

As human beings, we are fascinated by what makes us tick. We know that nature gave us certain biological appetites to ensure our survival, among those the need for water, food, sex, and love, but meeting these alone is not enough to ensure happiness. Scientists, and now managers, are realizing that people have a biological need to experience social rewards like praise, the thrill of innovation, and the satisfaction of acquiring new skills.

Though you may not be able to see them with the naked eye, parasites inhabit our everyday lives. From headlice to bird droppings, litterboxes to unfiltered water, you have brushed up against the most common way of life on our planet. In this unique book, John Janovy Jr., one of the world's preeminent experts on parasites, reveals what can humans learn from the most reviled yet misunderstood animals on Earth: lice, tapeworms, flukes, and maggots that can eat a lizard from the inside, and how these lessons help us negotiate our own complicated world.

The award-winning journalist Lisa Margonelli investigates the environmental and economic impact termites inflict on human societies in this fascinating examination of one of nature's most misunderstood insects.

The Origin of Humankind is Richard Leakey's personal view of the development of Homo sapiens. At the heart of his new picture of evolution is the introduction of a heretical notion: Once the first apes walked upright, the evolution of modern humans became possible and perhaps inevitable. From this one evolutionary step comes all the other evolutionary refinements and distinctions that set the human race apart from the apes.

Why are we the way we are? Why do some of us find it impossible to calm a quick temper or to shake anxiety? The debate has always been divided between nature and nurture, but as psychology professor Daniel P. Keating demonstrates in Born Anxious, new DNA science points to a third factor that allows us to inherit both the nature and the nurture of previous generations - with significant consequences.

Flush is both an urgent exploration of the world’s single most squandered natural resource, and a cri de coeur (or cri de colon?) for the vast, hidden value in our “waste.” Award-winning journalist and microbiologist Bryn Nelson, PhD, leads listeners through the colon and beyond with infectious enthusiasm, helping to usher in a necessary mental shift that could restore our balance with the rest of the planet and save us from ourselves.

Embracing the Wide Sky is a unique and brilliantly imaginative portrait of how we think, learn, remember and create, brimming with personal insights and anecdotes, and explanations of the most up-to-date, mind-bending discoveries from fields ranging from neuroscience to psychology and linguistics. This is a profound and provocative book that will transform our understanding and respect for every kind of mind.

While anger is a normal emotion, when it goes unmanaged, it can wreak havoc on everyone else's life, including your own. Whenever you are unable to control the fits of anger, the end results are often destructive, leading to problems in personal relationships, at work, and overall affecting your entire existence. Anger can damage your relationships and health when you don't express it at all, if you express it unsafe ways, or if you express it at the wrong time.

Every Living Thing centres on the rivalry pledged between two scientists, Linnaeus and Buffon, who, from 1743 to 1778 raced each other to complete an inventory of all life on Earth. Their focus was on scientific immortality and the core conception of our relationship to the natural world. Their catalogues were starkly different and showed a divergence of opinion on the creation of nature and humanity. Buffon advocating for a natural system of classification, while Linnaeus was dedicated to naming and classifying objects of nature.
