Stress is our internal response to an experience that our brain perceives as threatening or challenging. Trauma is our response to an experience in which we feel powerless or lacking agency. Until now, researchers have treated these conditions as different, but they actually lie along a continuum. Dr. Elizabeth Stanley explains the significance of this continuum, how it affects our resilience in the face of challenge, and why an event that's stressful for one person can be traumatizing for another.

From the development of the U-2 to the Stealth fighter, the never-before-told story behind America's high-stakes quest to dominate the skies. Skunk Works is the true story of America's most secret and successful aerospace operation. As recounted by Ben Rich, the operation's brilliant boss for nearly two decades, the chronicle of Lockheed's legendary Skunk Works is a drama of Cold War confrontations and Gulf War air combat, of extraordinary feats of engineering and human achievement against fantastic odds.

In The Open-Air Life, Swedish-American writer Linda McGurk introduces listeners to a wide array of Nordic customs and practices that focus on slowing down and spending more and more of ones’ time outdoors. An outdoorsy cousin of hygge, friluftsliv is what Nordic people do outside all day before they cozy up in front of the fireplace with their wool socks on and a cup of hot cocoa.

On the Alaska Peninsula, where exceptional landscapes are commonplace, a small river attracts attention far beyond its scale. Each year, from summer to early fall, brown bears and salmon gather at Brooks River to create one of North America's greatest wildlife spectacles. As the salmon leap from the cascade, dozens of bears are there to catch them, and thousands of people come to watch in person or on the National Park Service's popular Brooks Falls Bearcam. The Bears of Brooks Falls tells the story of this region and the bears that made it famous.

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.

In the years following her role as the lead author of the international best seller, Limits to Growth - the first book to show the consequences of unchecked growth on a finite planet - Donella Meadows remained a pioneer of environmental and social analysis until her untimely death in 2001. Thinking in Systems is a concise and crucial book offering insight for problem-solving on scales ranging from the personal to the global. Edited by the Sustainability Institute's Diana Wright, this essential primer brings systems thinking out of the realm of computers and equations and into the tangible world....

Cette série de six chroniques avec Serge Bouchard, anthropologue et spécialiste des peuples autochtones, nous offre un voyage au cœur de la géopolitique autochtone au Canada lors de l’arrivée des Européens.

In The Optimist, David Coggins tackled the techniques of fly-fishing and meditated on its virtues, recounting his triumphs and failures. Now, in The Believer, he deftly mixes travel, local cultures, further fishing challenges (some knee-buckling in their disappointment), and details his own experience as life and love crowd his time to fish.

With his inimitable combination of wit and wisdom, John Gierach once again celebrates the fly-fishing life in Standing in a River Waving a Stick and notes its benefits as a sport, philosophical pursuit, even therapy: "The solution to any problem-work, love, money, whatever-is to go fishing, and the worse the problem, the longer the trip should be." After all, fly-fishing does teach important life lessons, says Gierach-about solitude, patience, perspective, humor, and the sublime coffee break.

There's a silent epidemic in Western civilization, and it is right under our noses. Our jaws are getting smaller and our teeth crooked and crowded, creating not only aesthetic challenges but also difficulties with breathing. Sandra Kahn and Paul R. Ehrlich, a pioneering orthodontist and a world-renowned evolutionist, respectively, present the biological, dietary, and cultural changes that have driven us toward this major health challenge. They propose simple adjustments that can alleviate this developing crisis.

The Light Eaters is a deep immersion into the drama of green life and the complexity of this wild and awe-inspiring world that challenges our very understanding of agency, consciousness, and intelligence. In looking closely, we see that plants, rather than imitate human intelligence, have perhaps formed a parallel system.

Monsanto, a St. Louis chemical firm that became the world’s largest maker of genetically engineered seeds, merged with German pharma-biotech giant Bayer in 2018 - but its Roundup Ready® seeds, introduced 25 years ago, are still reshaping the farms that feed us. When researchers found trace amounts of the firm’s blockbuster herbicide in breakfast cereal bowls, Monsanto faced public outcry. Award-winning historian Bartow J. Elmore shows how the Roundup story is just one of the troubling threads of Monsanto’s past, many told here and woven together for the first time.

Nothing has had a more profound impact on the development of modern civilization than thermodynamics. Thermodynamic processes are at the heart of everything that involves heat, energy, and work, making an understanding of the subject indispensable for careers in engineering, physical science, biology, meteorology, and even nutrition and culinary arts. Get an in-depth tour of this vital and fascinating science in 24 enthralling lectures suitable for everyone from science novices to experts who wish to review elementary concepts and formulas.

No subject is bigger than reality itself, and nothing is more challenging to understand, since what counts as reality is undergoing continual revision and has been for centuries. The quest to pin down what's real and what's illusory is both philosophical and scientific, a metaphysical search for ultimate reality that goes back to the ancient Greeks. For the last 400 years, this search has been increasingly guided by scientists, who create theories and test them in order to define and redefine reality.

An "elegant", "engrossing" (Carol Tavris, Wall Street Journal) examination of what we think we know about the brain and why - despite technological advances - the workings of our most essential organ remain a mystery.

We're living in the midst of a scientific revolution that's captured the general public's attention and imagination. The aim of this new revolution is to develop a "theory of everything," a set of laws of physics that will explain all that can be explained, ranging from the tiniest subatomic particle to the universe as a whole. Here, readers will learn the ideas behind the theories and their effects upon our world, our civilization, and ourselves.

Fans of xkcd ask Munroe a lot of strange questions: What if you tried to hit a baseball pitched at ninety percent the speed of light? How fast can you hit a speed bump while driving and live? If there was a robot apocalypse, how long would humanity last? What if everyone only had one soulmate? What would happen if the moon went away? In pursuit of answers, Munroe runs computer simulations, pores over stacks of declassified military research memos, solves differential equations, and consults with nuclear reactor operators.

The James Webb Space Telescope is transforming the universe right before our eyes—and here, for the first time, is the inside account of how the mission originated, how it performs its miracles of science, and what its revolutionary images are revealing. Pillars of Creation tells the story of one of the greatest scientific achievements in the history of civilization, a $10 billion instrument with a staggeringly ambitious goal: unlocking the secrets of the cosmos.

Every culture is a unique answer to a fundamental question: What does it mean to be human and alive? In The Wayfinders, renowned anthropologist, winner of the prestigious Samuel Johnson Prize, and National Geographic Explorer-in-Residence Wade Davis leads us on a thrilling journey to celebrate the wisdom of the world's indigenous cultures.
