Before the discovery of insulin, diabetes was treated almost exclusively through diet, from subsistence on meat, to reliance on fats, to repeated fasting and near-starvation regimens. After two centuries of conflicting medical advice, most authorities today believe that those with diabetes can have the same dietary freedom enjoyed by the rest of us, leaving the job of controlling their disease to insulin therapy and other blood-sugar-lowering medications.

In the summer of 1921, Philo T. Farnsworth was not all that different from any other farmer's son in rural Idaho, until he came up with an idea that would change the world–and thrust him into a titanic struggle with one of the most monolithic monopolies in the world. Farnsworth's story of divine inspiration facing off against corporate avarice is a compelling–though seldom told–saga from the 20th century that is still relevant in the 21st.

Riveting and timely, a look at the research that is transforming our understanding of the cosmos in the quest to discover whether we are alone.

For years Charlie Burrell and his wife, Isabella Tree, farmed Knepp Castle Estate and struggled to turn a profit. By 2000, with the farm facing bankruptcy, they decided to try something radical. They would restore Knepp’s 3,500 acres to the wild. Using herds of free-roaming animals to mimic the actions of the megafauna of the past, they hoped to bring nature back to their depleted land. But what would the neighbors say, in the manicured countryside of modern England where a blade of grass out of place is considered an affront?

From University of Washington professor Chantel Prat comes The Neuroscience of You, a rollicking adventure into the human brain that reveals the surprising truth about neuroscience, shifting our focus from what’s average to an understanding of how every brain is different, exactly why our quirks are important, and what this means for each of us.

A little over 100 years ago, East Africa was terra incognita to most whites: a land largely unmapped, sparsely settled by Europeans, and teeming with wildlife. It was the hunter-adventurer's paradise, and by the early 20th century, a small, lionhearted clan of explorers and big-game hunters began leading safaris there for money.

Award-winning author, Stephen Hawley Martin, spent three years interviewing more than one hundred experts, ranging from noted quantum physicist, Henry Stapp, Ph.D., to the Director of the Windbridge Institute, Julie Beischel, Ph.D., to the Director of the Division of Perceptual Studies [DOPS] at the University of Virginia School of Medicine, Jim B. Tucker, M.D. The topics covered included research into near death experiences [NDEs], research into veracity of reports by psychic mediums, research concerning ESP and documented paranormal activity as well as children’s memories of past lives ...

In one of the most spellbinding accounts of men who go down to the sea in ships, the modern listener is given a seat in the whale boat of Owen Chase as he and his fellow crew and their captain make way in three boats after the wreckage of the Whaleship Essex. The account of how the Essex was wrecked inspired the infamous book Moby Dick and countless movies, including In the Heart of the Sea.

Beginning with Mt. Vesuvius, whose eruption in Roman times helped spark the science of geology, and ending in a lab in the West of England where mathematical models and lab experiments replace direct observation, Richard Fortey tells us what the present says about ancient geologic processes. He shows how plate tectonics came to rule the geophysical landscape and how the evidence is written in the hills and in the stones. And in the process, he takes us on a wonderful journey around the globe to visit some of the most fascinating and intriguing spots on the planet.

As development and subsequent habitat destruction accelerate, there are increasing pressures on wildlife populations. But there is an important and simple step toward reversing this alarming trend: Everyone with access to a patch of earth can make a significant contribution toward sustaining biodiversity. Bringing Nature Home has sparked a national conversation about the link between healthy local ecosystems and human well-being, and this audio edition will help broaden the movement. By acting on Douglas Tallamy's practical recommendations, everyone can make a difference.

Religious fundamentalists and biblical literalists present any number of arguments that attempt to disprove evolution. Those with a sympathetic ear often fail to critically examine these creationist claims, leading to an ill-informed public and, perhaps more troubling, ill-advised public policy. As Aron Ra makes clear, however, every single argument deployed by creationists in their attacks on evolution is founded on fundamental scientific, religious, and historical falsehoods - all of them.

Straight out of Joshua Tree, California, Desert Oracle is “The Voice of the Desert”: a field guide to the strange tales, singing sand dunes, sagebrush trails, artists and aliens, authors and oddballs, ghost towns and modern legends, musicians and mystics, scorpions and saguaros, out there in the sand. Desert Oracle is your companion at a roadside diner, around a campfire, in your tent or cabin (or high-rise apartment or suburban living room) as the wind and the coyotes howl outside at night.

Published in 1951, The Sea Around Us is one of the most remarkably successful books ever written about the natural world. This classic work remains as fresh today as when it first appeared. Carson's writing teems with stunning, memorable images - the newly formed Earth cooling beneath an endlessly overcast sky, the centuries of nonstop rain that created the oceans, giant squids battling sperm whales hundreds of fathoms below the surface, and incredibly powerful tides moving 100 billion tons of water daily in the Bay of Fundy.

Humanity has reached a critical moment. Our world is unsettled and rapidly changing, and we face existential risks over the next century. Various outcomes - good and bad - are possible. Yet our approach to the future is characterized by short-term thinking, polarizing debates, alarmist rhetoric, and pessimism. In this short, exhilarating book, renowned scientist and best-selling author Martin Rees argues that humanity’s prospects depend on our taking a very different approach to planning for tomorrow.

Teeming with unsuspected life, an extraordinary, interconnected ecosystem deep below the waves has a huge effect on our daily lives, influencing climate and weather systems, with the potential for much more—good or bad, depending on how it is exploited. Currently, the fantastic creatures that live in the deep—many of them incandescent in a world without light—and its formations capture and trap vast quantities of carbon that would otherwise poison our atmosphere, and novel bacteria as yet undiscovered hold the promise of potent new medicines.

In the past two decades, our understanding of the navigational and physiological feats that enable birds to cross immense oceans, fly above the highest mountains, or remain in unbroken flight for months at a stretch has exploded. What we've learned of these key migrations is nothing short of extraordinary. This breathtaking work of nature writing also introduces listeners to those scientists, researchers, and bird lovers trying to preserve global migratory patterns in the face of climate change and other environmental challenges.

For the last fifty years, we have been fighting a losing war on food. We have cut fat, reduced carbs, eliminated sugar, and attempted every conceivable diet only to find that eighty-eight million American adults are prediabetic, more than a hundred million have high blood pressure, and nearly half now qualify as obese. The harder we try to control what we eat, the unhealthier we become. Why?
