Ever since Darwin and The Descent of Man, the existence of humans has been attributed to our intelligence and adaptability. But in Catching Fire, renowned primatologist Richard Wrangham presents a startling alternative: our evolutionary success is the result of cooking. In a groundbreaking theory of our origins, Wrangham shows that the shift from raw to cooked foods was the key factor in human evolution.

The science on climate change has been clear for a very long time now. Yet despite decades of appeals, mass street protests, petition campaigns, and peaceful demonstrations, we are still facing a booming fossil fuel industry, rising seas, rising emission levels, and a rising temperature. With the stakes so high, why haven't we moved beyond peaceful protest? In this lyrical manifesto, noted climate scholar (and saboteur of SUV tires and coal mines) Andreas Malm makes an impassioned call for the climate movement to escalate its tactics in the face of ecological collapse.

Fire is rarely out of the headlines, from large natural wildfires raging across the Australian or Californian countrysides to the burning of buildings such as the disasters of Grenfell tower and Notre Dame. Fire on these scales can represent a serious risk to human life and property. But the advent of fire made and controlled by humans also represented a crucial point in our evolution, allowing us to cook our food, forge our weapons, and warm our homes.

The Pyrocene tells the story of what happened when a fire-wielding species, humanity, met an especially fire-receptive time in Earth's history. Since terrestrial life first appeared, flames have flourished. Over the past two million years, however, one genus gained the ability to manipulate fire, swiftly remaking both itself and eventually the world. We developed small guts and big heads by cooking food; we climbed the food chain by cooking landscapes; and now we have become a geologic force by cooking the planet.

Throughout history, when threatened by wildfires our only defense was to pray for rain and run—until aircraft changed the way we fight fires. Beginning with the Canadian "H-Boats" in 1924, aircraft have become indispensable in detecting and extinguishing wildfires. Fire Eaters tells the incredible stories of the Ontario Provincial Air Service, the first government aerial fire suppression organization in history; one of its pilots, Carl Crossley, who invented the water scoop-up and drop-off system; and the Canadair CL-215, the first purpose-built water bomber.

There is no precedent in postwar American history for the destruction of the town of Paradise, California. On November 8, 2018, the community of 27,000 people was swallowed by the ferocious Camp Fire, which razed virtually every home and killed at least 85 people. Fire in Paradise is a dramatic and moving narrative of the disaster based on hundreds of in-depth interviews with residents, firefighters and police, and scientific experts.

Why do organisms grow old and die? What are the theories of aging? Does the Free Radical Theory of Aging still stack up? How do cells decide when to divide, differentiate or die? What factors accelerate the aging process? This essay takes a look at these issues and would thus be useful to students who want to know more about the processes that control cell death. The essay also documents the more extreme measures that some people have taken in the pursuit of eternal youth.

Elemental, fierce, and full of wonder, the Cairngorm mountains are the high and rocky heart of Scotland. To know them would take forever, to love them demands a kind of courageous surrender. In The Hidden Fires, Merryn Glover undertakes that challenge with Nan Shepherd as companion and guiding light. Following in the footsteps and contours of The Living Mountain, she explores the same landscapes and themes as Shepherd's seminal work

A valuable discovery under the world's second-largest temperate wetland and in the traditional lands of the Cree and Ojibway casts light on the growing conflict among resource development, environmental stewardship, and Indigenous rights. In this colorful tale, Virginia Heffernan draws on her bush and newsroom experiences to illustrate the complexities of resource development at a time when Indigenous rights are becoming enshrined globally.

The Esperanza Fire started October 26, 2006, in the San Jacinto Mountains above the Banning Pass near Cabazon, California. It destroyed 41,000 acres and dozens of homes and cost the taxpayers $16 million dollars. But by far the highest costs of the conflagration were the lives of the five-man crew of Engine 57, the first engine crew ever killed fighting a wildland blaze. Fire and superheated gases had erupted in a freak "area ignition," sending flames racing across three-quarters of a mile in mere seconds, engulfing the crew and the house they were defending.

Norman MacLean spent the last 14 years of his life determined to sift through grief and controversy in search of the truth behind the Mann Gulch tragedy, one of the worst disasters in the history of the Forest Service. Young Men and Fire is the culmination of his investigations. It is a story about honor, death, compassion, and the human spirit.

More than half a billion years ago, our world was completely covered by glaciers, a "Snowball Earth" that persisted for millions of years. Incredibly, this unimaginable cold led to the remarkable diversification of life on earth known as the Cambrian explosion. With a geologist's eye and a knack for storytelling, Graham Shields explores when and how such inhospitable conditions enabled animals to evolve, radiate, and diversify into our earliest ancestors.

On February 22, 1978, a devastating freight train derailment drastically altered Waverly, Tennessee, and its place in history. This was one of the worst train explosions of the twentieth century, killing sixteen people, injuring hundreds more, and causing millions of dollars in damage. What could have been dismissed as a single community's terrible misfortune instead became the catalyst for radical change, including the formation of FEMA, much-needed reforms in emergency response training, and the creation and enforcement of national and state safety regulations.

The environment is collapsing at a rapid rate, and in increasingly unpredictable ways. Everyone knows that this is happening, and yet the only politics that is emerging to tackle it are coming from the increasingly nativist far-right. How should the left respond? In Planet on Fire, two rising stars of the British left lay down a set of proposals for a fundamental re-shaping of the global economy and offer a road map for tackling climate breakdown.

If you live on a rapidly changing planet, you'd be wise to learn how it works. The giant old forests on a skinny stretch of land on the far west coast of North America have a lot to say about living in a twitchy world.

Crystal Fire is a tale of the human factors in technology; the pride and jealousies coupled with scientific and economic aspiration that led to the creation of modern microelectronics and ignited the greatest technological explosion in history.

On December 16, 1947, two physicists at Bell Laboratories, John Bardeen and Walter Brattain, jabbed two electrodes into a sliver of germanium half an inch long. The electrical power coming out of that piece of germanium was 100 times stronger than what went in. In that moment, the transistor was invented and the information age began. Crystal Fire recounts the story of the transistor team at Bell Labs, led by William Shockley, who shared the Nobel Prize with Bardeen and Brattain.

Every year, droughts, floods, and fires impact hundreds of millions of people and cause massive economic losses. Climate change is making these catastrophes more dangerous. Now. Not in the future: now. This book describes how and why climate change is already fomenting dire consequences and will certainly make climate disasters worse in the near future.

Bringing together the best and most interesting science stories appearing in Quanta Magazine over the past five years, Alice and Bob Meet the Wall of Fire reports on some of the greatest scientific minds as they test the limits of human knowledge. It communicates science by taking it seriously, wrestling with difficult concepts, and clearly explaining them in a way that speaks to our innate curiosity about our world and ourselves.
