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.

One of the biggest discoveries in physics, the quest for the Higgs boson demonstrates the value of a good theory. In July 2012, a Higgs-like particle was found near the energies scientists predicted. Now, armed with better evidence and better questions, the scientific process continues. In this audiobook, we’ve gathered our best reporting to explain that process - the theories, the search, the discovery, and the ongoing questions.

Noted transcendentalist Henry David Thoreau spent two years, two months, and two days chronicling his near-isolation in the small cabin he built in the woods near Walden Pond on land owned by his mentor, the father of Transcendentalism, Ralph Waldo Emerson. Immersing himself in nature and solitude, Thoreau sought to develop a greater understanding of society amidst a life of self-reliance and simplicity. Originally published in 1854, Walden remains one of the most celebrated works in American literature.

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 definitive account of how a discarded strand of hair found in Thomas Jefferson’s Bible led to a sweeping, multi-year genomic investigation, drawing on technological advances in DNA to finally resolve a 200-year national controversy. “Written with the gravitas of history and the pace of a...

What is human consciousness, and how is it possible? This question fascinates thinking people from poets and painters to physicists, psychologists, and philosophers. From Bacteria to Bach and Back is Daniel C. Dennett's brilliant answer, extending perspectives from his earlier work in surprising directions, exploring the deep interactions of evolution, brains, and human culture.

Terrible lizards. That’s what the word dinosaurs means. Yet dinosaurs are not true lizards, and they are not necessarily terrible, either. Paleontologists have overturned many misconceptions, and in Dinosaurs!, we look at what the latest research tells us and what we still have to learn about these endlessly fascinating creatures. 

Vital research is starting to challenge long-standing assumptions about gender identity and biological sex, such as work that indicates the brain is a “mosaic” of traits rather than a “male” and “female” brain. Growing knowledge of the genetic complexities of sexual determination is changing the way the medical community treats intersex individuals, and in this audiobook, The New Science of Sex and Gender, we not only examine the latest studies in biology, medicine, and psychology but also, more importantly, their bearing on healthcare, identity, and access. 

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. 

This binaural audio recording features the American Goldfinch birdsong recorded in its natural habitat in Iowa’s Yellow River State Forest near a delicate babbling river stream together with other birds, insects, and ground creatures. The American Goldfinch is a small passerine bird native to North America, making it a key species in the local avifauna. American Goldfinch birdsong consists of bright melodious chirps, often delivered in flight and coinciding with each undulation.

Before 1910 the American chestnut was one of the most common trees in the eastern United States. An important natural resource, chestnut wood was preferred for woodworking, fencing, and building construction, as it was rot resistant and straight grained. The hearty and delicious nuts also fed wildlife, people, and livestock.

When Dr. David Hosack tilled the country's first botanical garden in the Manhattan soil more than 200 years ago, he didn't just dramatically alter the New York landscape; he left a monumental legacy of advocacy for public health and wide-ranging support for the sciences. In melodic prose, historian Victoria Johnson eloquently chronicles Hosack's tireless career to reveal the breadth of his impact. The result is a lush portrait of the man who gave voice to a new, deeply American understanding of the powers and perils of nature.

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".

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.

Rachel Herz uncovers the fascinating and surprising facts that affect food consumption. Why You Eat What You Eat mixes the social with the scientific to uncover how psychology, neurology, and physiology shape our relationship with food and how food alters the relationships we have with ourselves and with one another.

Each year across the United States, there are mysterious and unexplainable firsthand encounters by average people. These encounters beg the question, do monsters exist? From east to west across the US, professionals are actively researching these encounters to prove once and for all that these creatures do exist. American Cryptids takes you on a journey across the country, visiting each state along the way.

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.
