When Speaker Newt Gingrich greeted Dr. David Lewis in his office overlooking the National Mall, he looked at Dr. Lewis and said: "You know you’re going to be fired for this, don’t you?" "I know," Dr. Lewis replied, "I just hope to stay out of prison." Gingrich had just read Dr. Lewis' commentary in Nature, titled "EPA Science: Casualty of Election Politics".

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.

Instruments of modern physics can measure the energies of the electromagnetic spectrum, but these energies only account for roughly 4 percent of the total identifiable mass-energy of the universe. What makes up the remaining 96%? In this scientifically based yet accessible analysis, Yury Kronn, Ph.D., explores the nature of the remaining 96% of the universe’s mass-energies. Contemporary science calls this mass energy “dark matter,” and the ancients called it life force, prana, or chi.

In recent years, techno-scientific progress has started to utterly transform our world - changing it almost beyond recognition. In this extraordinary new audiobook, renowned philosopher Slavoj Zizek turns to look at the brave new world of Big Tech, revealing how, with each new wave of innovation, we find ourselves moving closer and closer to a bizarrely literal realisation of Marx's prediction that 'all that is solid melts into air'.

For more than a century, the interplay between private, investor-owned electric utilities and government regulators has shaped the electric power industry in the United States. Provision of an essential service to largely dependent consumers invited government oversight and ever more sophisticated market intervention. The industry has sought to manage, coopt, and profit from government regulation. In The Power Brokers, Jeremiah Lambert maps this complex interaction from the late 19th century to the present day.

Coursing through the Atlantic Ocean is a powerful current with a force 300 times that of the mighty Amazon. Ulanski explores the fascinating science and history of this sea highway known as the Gulf Stream, a watery wilderness that stretches from the Caribbean to the North Atlantic. Spanning both distance and time, Ulanski's investigation reveals how the Gulf Stream affects and is affected by every living thing that encounters it--from tiny planktonic organisms to giant bluefin tuna, from ancient mariners to big-game anglers.

Solar energy, once a niche application for a limited market, has become the cheapest and fastest-growing power source on earth. What's more, its potential is nearly limitless. But in Taming the Sun, energy expert Varun Sivaram warns that the world is not yet equipped to harness erratic sunshine to meet most of its energy needs. And if solar's current surge peters out, prospects for replacing fossil fuels and averting catastrophic climate change will dim.

In The Elements We Live By, physicist and award-winning author Anja Røyne takes us on an astonishing journey through chemistry and physics, introducing the building blocks from which we humans - and the world - are made. Not only does Røyne explain why our bodies need iron, phosphorus, silicon, potassium, and many more elements in just the right amounts in order to function, she also leads us around the world to where these precious elements are found (some of them in ever-shrinking quantities).

For decades, Starre Vartan—like most women—was told that having a woman's body meant being weaker than men. Like many women, she mostly believed it. Not anymore. Following a half decade of research into the newest science, Vartan shows in The Stronger Sex that women's bodies are incredibly powerful, flexible, and resilient in ways men's bodies aren't. Tossing aside the narrow notion of the tall, muscular man as the measure of strength, Vartan reveals the ways that women surpass men in endurance, flexibility, immunity, pain tolerance, and the ultimate test of any human body: longevity.

Welcome to a journey of exploration, self-discovery, and healing. This book will guide you through the wonders of your own body—the ultimate healing machine. It's a marvel, a mystery, and a miracle, all wrapped into one. We'll embark on a quest to understand the extraordinary processes that allow your body to heal itself, from the intricate cellular ballet of repair and regeneration to the defensive strategies of the ever-vigilant immune system.

The child of South-Asian migrants, Kazim Ali was born in London, lived as a child in the cities and small towns of Manitoba, and made a life in the United States. As a man passing through disparate homes, he has never felt he belonged to a place. And yet, one day, he finds himself thinking of Jenpeg, a community thrown up around the building of a hydroelectric dam on the Nelson River, where he once lived for several years as a child. Does the town still exist, he wonders? Is the dam still operational?

Since 2006, Twitter has grown from 100 obsessive users to more than 500 million today - over 32 million of those in the UK alone. But how did such a radical transformation happen in just five years, and what does it mean for business, politics and the internet?

Today just about everything we've known and relied on (our natural environment, economy, societies, cultures and institutions) is changing dramatically—too often for the worse. Without radical new approaches, our planet will become unrecognizable as well as poorer, more violent, more authoritarian. Thomas Homer-Dixon calls on his extraordinary knowledge of complexity science, of how societies work and can evolve, and of our capacity to handle threats, to show that we can shift human civilization onto a new path if we mobilize our minds, spirits, imaginations and collective values.

The coal-mining town of Fushun in China’s Northeast is home to a monstrous open pit. First excavated in the early twentieth century, this pit grew like a widening maw over the ensuing decades, as various Chinese and Japanese states endeavored to unearth Fushun’s purportedly “inexhaustible” carbon resources. Today, the depleted mine that remains is a wondrous and terrifying monument to fantasies of a fossil-fueled future and the technologies mobilized in attempts to turn those developmentalist dreams into reality.

Deepwater Horizon was supposed to be the cutting edge of energy exploration: drilling 5,000 feet below the surface of the Gulf of Mexico, the $560 million rig would be indispensable in helping to solve the ongoing energy crisis. Then, on April 20, 2010, BP’s dismal safety record came home to roost.

She Has Her Mother’s Laugh presents a profoundly original perspective on what we pass along from generation to generation. Charles Darwin played a crucial part in turning heredity into a scientific question, and yet he failed spectacularly to answer it. The birth of genetics in the early 1900s seemed to do precisely that. Gradually, people translated their old notions about heredity into a language of genes. As the technology for studying genes became cheaper, millions of people ordered genetic tests to link themselves to missing parents, to distant ancestors, to ethnic identities....

The Terminator meets Zombieland. "A new twist on time travel dystopia." ★★★★★ "On edge of seat till 2am. Mindblowing." ★★★★★ "There is nothing same-old about this story." ★★★★★ I can see the future. But I can't stop the apocalypse. It can't be real, can it? Each time I slip into the future, I bring back more proof. Humanity is on the brink of a genetically-engineered apocalypse. ⌛ Bodies rotting in the streets. ⌛ Wilderness eating away at my hometown. ⌛ Zombies hunting down the few survivors. I'm the only one who can stop it. Because for me, it hasn't ...

American technological prowess used to be unrivaled. But because of globalization, and with the blessing of the US government, once proprietary materials, components, and technologies are increasingly commercialized outside the United States. Nowhere is this more dangerous than in China's monopoly of rare earth elements - materials that are essential for nearly all modern consumer goods, gadgets, and weapons systems.
