In 2017, author Shanna Swan and her team of researchers completed a major study. They found that over the past four decades, sperm levels among men in Western countries have dropped by more than 50 percent. They came to this conclusion after examining 185 studies involving close to 45,000 healthy men. The result sent shockwaves around the globe - but the story didn’t end there.

Temple Grandin’s professional training as an animal scientist and her history as a person with autism have given her a perspective like that of no other expert in the field. Grandin and coauthor Catherine Johnson present their powerful theory that autistic people can often think the way animals think—putting autistic people in the perfect position to translate “animal talk.”

Why evolution is more than just a theory: it is a fact. In all the current highly publicized debates about creationism and its descendant "intelligent design", there is an element of the controversy that is rarely mentioned: the evidence, the empirical truth of evolution by natural selection.

Just in the last three years a flood of new scientific findings, driven by revelations discovered in the human genome, has provided compelling new answers to many long-standing mysteries about our most ancient ancestors, the people who first evolved in Africa and then went on to colonize the whole world. Nicholas Wade weaves this host of news-making findings together for the first time into an intriguing new history of the human story before the dawn of civilization.

Are there other dimensions beyond our own? Is time travel possible? Can we change the past? Are there gateways to parallel universes? All of us have pondered such questions, but there was a time when scientists dismissed these notions as outlandish speculations. Not any more. Today, they are the focus of the most intense scientific activity in recent memory. In Hyperspace, Michio Kaku offers the first book-length tour of the most exciting (and perhaps most bizarre) work in modern physics.

More than 200 million years ago, geological forces split apart the continents. Isolated from each other, the two halves of the world developed radically different suites of plants and animals. When Christopher Columbus set foot in the Americas, he ended that separation at a stroke. Driven by the economic goal of establishing trade with China, he accidentally set off an ecological convulsion as European vessels carried thousands of species to new homes across the oceans.

This survival guide for new pilots identifies the pitfalls waiting inside the killing zone, the period from 50 to 350 flight hours when they leave their instructors behind and fly as pilot in command for the first time. Although they're privately certified, many of these unseasoned aviators are unaware of the potential accidents that lie ahead while trying to build decision-making skills on their own - many times falling victim to inexperience.

With acuity, humor, and respect for human diversity, The Shortest History of Sex reveals where the many facets of our sexuality—chemical, anatomical, behavioral, social—come from. Chasing down our evolutionary family tree, from the first aquatic creatures to primate societies, David Baker sheds light on our baffling array of passions, impulses, and fetishes, and guides us toward a clear understanding of one of the deepest, most abiding forces of human nature.

In The Way of the Hermit, Ken shares the remarkable story of his life for the very first time. Told with humor and compassion, his unique insights allow us to glimpse the awe and wonder of a life lived in nature and offer wisdom on how each of us can escape the pressures and stresses of modern life.

In May 2016, Fort McMurray, the hub of Canada’s oil industry and America’s biggest foreign supplier, was overrun by wildfire. The multi-billion-dollar disaster melted vehicles, turned entire neighborhoods into firebombs, and drove 88,000 people from their homes in a single afternoon. Through the lens of this apocalyptic conflagration—the wildfire equivalent of Hurricane Katrina—John Vaillant warns that this was not a unique event, but a shocking preview of what we must prepare for in a hotter, more flammable world.

Ants number in the ten quadrillions, and they have been here since the Jurassic era. Inside an anthill, you'll find high drama worthy of a royal court; and between colonies, high-stakes geopolitical intrigue is afoot. Just like us, ants grow crops, raise livestock, tend their young and infirm, and make vaccines. And, just like us, ants have a dark side: They wage war, despoil environments, and enslave rivals - but also rebel against their oppressors.

Earth is 4.5 billion years old. In just a fraction of that time, one species among countless others has conquered it. Us. We are the most advanced and most destructive animals ever to have lived. What makes us brilliant? What makes us deadly? What makes us sapiens? In this bold and provocative audiobook, Yuval Noah Harari explores who we are, how we got here, and where we're going.

Two-thirds of us have experienced at least one adverse childhood experience, or ACE, such as abuse, neglect, parental substance dependence, or mental illness. Even though these events may have occurred long ago, they have the power to haunt us long into adulthood, and now we have found that they may even contribute to lifelong illness. Dr. Nadine Burke Harris, the founder/CEO of the Center for Youth Wellness and recipient of the Arnold P. Gold Foundation Humanism in Medicine Award, expands on similar topics as in her popular TED talk.

Come dive into one of the curiously delightful conversations overheard at National Geographic’s headquarters, as we follow explorers, photographers, and scientists to the edges of our big, weird, beautiful world. Hosted by Peter Gwin and Amy Briggs.

Plants play a critical role in how we experience our environment. They create calming green spaces, provide oxygen for us to breathe, and nourish our senses. In The Nature of Plants, ecologist and nursery owner Craig Huegel demystifies the complex lives of plants and provides listeners with an extensive tour into their workings.

Quantum theory is weird. As Niels Bohr said, if you aren’t shocked by quantum theory, you don’t really understand it. For most people, quantum theory is synonymous with mysterious, impenetrable science. And in fact for many years it was equally baffling for scientists themselves. In this tour de force of science history, Manjit Kumar gives a dramatic and superbly written account of this fundamental scientific revolution.

Celebrated storyteller and historian Edward Dolnick leads us through a compelling true adventure as the paleontologists of the first half of the 19th century puzzled their way through the fossil record to create the story of dinosaurs we know today. The tale begins with Mary Anning, a poor, uneducated woman who had a sixth sense for finding fossils buried deep inside cliffs; and moves to a brilliant, eccentric geologist named William Buckland.
