As a botanist and professor of plant ecology, Robin Wall Kimmerer has spent a career learning how to ask questions of nature using the tools of science. As a Potawatomi woman, she learned from elders, family, and history that the Potawatomi, as well as a majority of other cultures indigenous to this land, consider plants and animals to be our oldest teachers.

La Ruota di Medicina degli indiani d'America è la Ruota della Natura e racchiude in sé l'intera cultura e le tradizioni dei nativi americani: è la simbolica testimonianza della loro spiritualità, del rapporto vivo e vero che essi intrattengono da sempre con la natura. La Ruota di medicina ci fa scoprire che la natura non è un oggetto al nostro servizio, ma un sistema complesso e vivente che continuamente si trasforma, i cui equilibri dipendono anche da noi e dal nostro comportamento quotidiano nei suoi confronti.

Genetic engineering, which refers to the direct manipulation of DNA, became a reality in the 1970s. In this audiobook, we take a look at how far the field has come, starting with a revolutionary gene-editing tool called CRISPR that’s taking the research world by storm. We then examine how CRISPR and other approaches are being investigated to treat disease, the fantastic-sounding research being done in synthetic biology, controversial efforts in modifying crops and saving species, as well as the numerous ethical issues raised in these areas.

This fascinating and highly accessible book presents fantastic but totally feasible projections of what your brain may be capable of in the near future. It shows how scientific breakthroughs and amazing research are turning science fiction into science fact. In this brave new book, you'll explore.

From increasingly severe storms to collapsing coral reefs to the displacement of Syrian citizens, in this audiobook we examine the effects of Earth’s changing climate on weather systems, ecosystems, and human habitability and what this means for our future.

This audiobook, Tomorrow's Medicine, looks at some of the more fascinating areas where technology that could transform health is being developed, including cybernetics, regenerative medicine, nanotechnology, and genetically tailored treatments. Although many of these advances may not be ready to treat humans for many years, some of them may someday profoundly change - and extend - our lives. As exciting as the possibilities are to extend both the length and quality of life, immortality - or at least agelessness - may be forever out of our reach.

Anxiety and depression are two of the most common conditions affecting mental health and overall quality of life, but there are tools for managing them. In this audiobook, we’ll explore how depression shows up in the brain, different manifestations of depression and anxiety, various talk therapies, technological innovations, lifestyle interventions, and more.

We humans are a strange bunch. We have self-awareness and yet often act on impulses that remain hidden. How did we get here? What is to become of us? To these age-old questions, science has in recent years brought powerful tools and reams of data, and in this audiobook, Becoming Human, we look at what this data has to tell us about who we are.

In this audiobook, The Human Odyssey, we explore the evolution of those characteristics that make us human. The first section looks at our family tree and why some branches survived and not others. Swings in climate are emerging as a factor in what traits succeeded and failed; meanwhile, DNA analyses show that Homo sapiens interbred with other human species, which played a key role in our survival.

From the colonial era through the mid-twentieth century, America's flocks played a key role in the nation's development. Furthermore, much consternation centered around the sheep the United States lacked, so that dependency on foreign wool became a full-blown crisis in wartime. But more than just providers of wool, sheep were valued for their meat, for their byproducts after slaughter, and even for their efficiency at lawn maintenance.

America's Great Plains once possessed one of the grandest wildlife spectacles of the world, equaled only by such places as the Serengeti, the Masai Mara, or the veld of South Africa. Pronghorn antelope, gray wolves, bison, coyotes, wild horses, and grizzly bears: less than 200 years ago these creatures existed in such abundance that John James Audubon was moved to write "it is impossible to describe or even conceive the vast multitudes of these animals".

Filled with catchall research, American Hemp examines what this new domestic crop can be used for, what makes it a superior product, and what made it illegal in the first place; the book also delves into the many health and medical benefits of the plant. Hobbs weighs in on how hemp can improve existing industries, from farming to energy to 3D printing, plus how it can make a serious impact on climate change by removing toxins from the soil and by decreasing our dependence on plastics and fossil fuels.

In the tradition of Peter Matthiessen's Wildlife in America or Aldo Leopold, Brenda Peterson tells the 300-year history of wild wolves in America. It is also our own history, seen through our relationship with wolves. The earliest Americans revered them. Settlers zealously exterminated them. Now, scientists, writers, and ordinary citizens are fighting to bring them back to the wild. Peterson, an eloquent voice in the battle for 20 years, makes the powerful case that without wolves, not only will our whole ecology unravel, but we'll lose much of our national soul.

Roderick Nash's classic study of changing attitudes toward wilderness during American history, as well as the origins of the environmental and conservation movements, has received wide acclaim since its initial publication in 1967. For the fifth edition, Nash has written a new preface and epilogue that brings Wilderness and the American Mind into dialogue with contemporary debates about wilderness.

Wild American ginseng, America's most famous medicinal plant, is in trouble. In plain prose, James McGraw explains why as he translates the latest in ecological and conservation science findings on this unassuming understory herb. As the world's foremost authority on wild ginseng, McGraw is uniquely poised to present this story based on more than twenty years of uninterrupted field research.

Award-winning author Thom Hatch presents the definitive biography of George Bird Grinnell (1849-1938), who was recognized in his time as "The Father of American Conservation." This book chronicles not only Grinnell's life, but also offers a history of his accomplishments in saving the wildlife and natural resources of this country. A remarkable man, Grinnell was known as a model of intellectual diversity, integrity, and professional dedication.

On June 5, 1981, the scientific community received a wake-up call from the CDC in the form of a terrible new illness that the world would soon know as AIDS. Three decades later, remarkable progress has been made, but much more remains to be understood and to be done. In this audiobook, we explore where the disease came from, how it works, how it spreads, the search for a vaccine, and cultural and sociological factors.

The onset of cold weather brings out the boots, coats, gloves - and the stoplight-red “Flu Shots Available Here” signs in drugstore windows. For many scientists and public health specialists alike, flu season has become a little like Russian Roulette. The likelihood of a deadly pandemic outbreak of influenza is not far from reality considering the nature of some of the different viral strains. In this book, we delve into the science of the flu, starting with past pandemics and what we can learn from them.

We humans tend to think that we are unique in our intelligence, social skill, and depth of emotion, but we think too much of ourselves. The animal kingdom teems with hidden stories of the weird and fascinating, and in Amazing Animals, we gather recent research on animal behavior, including surprising discoveries of how animals think and feel, from man’s best friend to some of the earth’s oddest creatures.

How did life begin on Earth? Does it exist elsewhere? What would those life forms be like? These fundamental questions about the nature of life and our own cosmic significance are endlessly fascinating. In this book, we present several theories on the origin of life, some of its extreme and surprising forms, and the ongoing search for signs - or sentience - on distant worlds.
