At age 47, a mother of two, Debbie Moderow was not your average musher in the Iditarod, but that's where she found herself when, less than 200 miles from the finish line, her dogs decided they didn't want to run anymore. After all her preparation, after all the careful management of her team, and after their running so well for over a week, the huskies balked. But the sting of not completing the race after coming so far was nothing compared to the disappointment Moderow felt in having lost touch with her dogs.

In Dragons in the Snow, Power delves into the research and science behind avalanche forecasting and rescue, weaving in the art of backcountry skiing as well as dramatic tales of avalanche accidents, rescues, and recoveries. And he paints compelling portraits of the men and women who have made the study of avalanches their life's work. The tales told by these avalanche forecasters, as well as the stories of the backcountry riders who may "wake the dragon" make for not just a compelling listen, but also a powerful tool for raising avalanche awareness.

From late 1872 to 1876, H.M.S. Challenger explored the world's oceans. Conducting deep sea soundings, dredging the ocean floor, recording temperatures, observing weather, and collecting biological samples, the expedition laid the foundations for modern oceanography. Following the ship's naturalists and their discoveries, earth scientist Doug Macdougall engagingly tells a story of Victorian-era adventure and ties these early explorations to the growth of modern scientific fields.

Everyone has heard the story of DNA as the story of Watson, Crick, and Rosalind Franklin, but knowing the structure of DNA was only part of a greater struggle to understand life's secrets. Life's Greatest Secret is the story of the discovery and cracking of the genetic code, the thing that ultimately enables a spiraling molecule to give rise to the life that exists all around us. This great scientific breakthrough has had far-reaching consequences for how we understand ourselves and our place in the natural world.

How does soap know what's dirt? How do magnets work? Why do ice cubes crackle in your glass? And how can you keep them quiet? These are questions that torment us all. Now Robert L. Wolke, professor emeritus of chemistry at the University of Pittsburgh, provides definitive - and amazingly simple - explanations for the mysteries of everyday life.

Zurn and Bassett—identical twins who write that their book "represents the thought of one mind and two bodies"—harness their respective expertise in the humanities and the sciences to get irrepressibly curious about curiosity. They identify three styles of curiosity—the busybody, who collects stories, creating loose knowledge networks; the hunter, who hunts down secrets or discoveries, creating tight networks; and the dancer, who takes leaps of creative imagination, creating loopy ones.

We spend a third of our lives in bed, but how much do we really understand about what happens when we go to sleep? What's the right amount? Why do we experience jet lag? Is snoring normal? Enter Dr. Meir Kryger, a world authority on the science of sleep, with a comprehensive guide to the science of slumber that combines detailed case studies and pragmatic advice.

Elixir spans five thousand years, from the beginnings of civilization to the parched American Sun Belt of today. It is a story of human endeavor: our present-day interaction with this most essential resource has deep roots in the remote past, and every human culture has been shaped by its relationship to water.

First published in 1998, this perennial best seller distills more than 400 exciting tales of heroism from the 150,000 search-and-rescue missions carried out by the National Park Service since Yellowstone was established as the first national park in 1872. Updated to include the most notable incidents through 2004 (including the Park Service's efforts to protect the nation's treasures following 9/11), the new edition features recent rescues and rescue attempts from the icy slopes of Mt. Rainer to the seas off of Acadia National Park.

John Ratey, best-selling author and clinical professor of psychiatry at Harvard Medical School, lucidly explains the human brain's workings, and paves the way for a better understanding of how the brain affects who we are.

By giving us a greater understanding of how the brain responds to the guidance of its user, he provides us with knowledge that can enable us to improve our lives.

In 1963 Colin Fletcher became the first man to walk the length of Grand canyon, below the Rim. It began with a dream, when he and a friend detoured from a cross-country trip to take a hurried look at the great natural wonder. Standing on the Rim, surrounded by the profound and almost mystical silence, Fletcher knew that something had happened to the way he looked at things. He also knew that the Canyon, with its depths and distances, cliffs, buttes, and hanging terraces, beckoned to him, calling him on a journey that would challenge both his body and his mind.

The Internet and smartphone are just the latest in a 250-year-long cycle of disruption that has continuously changed the way we live, the way we work, and the way we interact. The coming Augmented Age, however, promises a level of disruption, behavioral shifts, and changes that are unparalleled. While consumers today are camping outside of an Apple store waiting to be one of the first to score a new Apple Watch or iPhone, the next generation of wearables will be able to predict if we're likely to have a heart attack and recommend a course of action.

Last Chance Mustang is the story of Samson, a formerly free-roaming, still wild-at-heart American mustang that was plucked from his mountainous Nevada home and thrown into the domestic horse world, where he was brutalized and victimized. After years of abuse, Samson had evolved into a hateful and hated, maladjusted beast - until the day he found his way to a rural Illinois farm, an ill-equipped owner, and one last chance.

In this Very Short Introduction, Warwick Vincent outlines the essential features of lake environments and their biology, offering an up-to-date view of lake ecosystems. Vincent traces the origins of lake science (limnology) from the seminal work of Francois Forel on Lake Geneva at the edge of the Swiss Alps, to modern approaches such as environmental sensors, satellite observations, stable isotope analysis, and DNA-based technologies which are used to probe the microbial life support systems that lead from sunlight to fish.

Ask a scientist about Hollywood, and you'll probably get eye rolls. But ask someone in Hollywood about science, and they'll see dollar signs: Moviemakers know that science can be the source of great stories, with all the drama and action that blockbusters require. That's a huge mistake, says Randy Olson: Hollywood has a lot to teach scientists about how to tell a story - and, ultimately, how to do science better. With Houston, We Have a Narrative, he lays out a stunningly simple method for turning the dull into the dramatic.

How much do you know about the meat on your dinner plate? Journalist Christopher Leonard spent more than a decade covering the country's biggest meat companies, including four years as the national agribusiness reporter for the Associated Press. Now he delivers the first comprehensive look inside the industrial meat system, exposing how a handful of companies executed an audacious corporate takeover of the nation's meat supply.

Enrico Fermi is unquestionably among the greats of the world's physicists, the most famous Italian scientist since Galileo. Called "the Pope" by his peers, he was regarded as infallible in his instincts and research. His discoveries changed our world; they led to weapons of mass destruction and conversely to life-saving medical interventions. This unassuming man struggled with issues relevant today, such as the threat of nuclear annihilation and the relationship of science to politics.
