In Wicked Plants, Stewart takes on over two hundred of Mother Nature’s most appalling creations. It’s an A to Z of plants that kill, maim, intoxicate, and otherwise offend. You’ll learn which plants to avoid (like exploding shrubs), which plants make themselves exceedingly unwelcome (like the vine that ate the South), and which ones have been killing for centuries (like the weed that killed Abraham Lincoln's mother). Menacing botanical illustrations and splendidly ghastly drawings create a fascinating portrait of the evildoers that may be lurking in your own backyard. Drawing on history, medicine, science, and legend, this compendium of bloodcurdling botany will entertain, alarm, and enlighten even the most intrepid gardeners and nature lovers.

    In the 1970s, he sent two prize students, Tim Plowman and Wade Davis, to follow in his footsteps and unveil the botanical secrets of coca, the notorious source of cocaine, a sacred plant known to the Inca as the Divine Leaf of Immortality.A stunning account of adventure and discovery, betrayal and destruction, One River is a story of two generations of explorers drawn together by the transcendent knowledge of Indian peoples, the visionary realms of the shaman, and the extraordinary plants that sustain all life in a forest that once stood immense and inviolable.

    Today’s "machine-learning" systems, trained by data, are so effective that we’ve invited them to see and hear for us?and to make decisions on our behalf. But alarm bells are ringing. Recent years have seen an eruption of concern as the field of machine learning advances. When the systems we attempt to teach will not, in the end, do what we want or what we expect, ethical and potentially existential risks emerge. Researchers call this the alignment problem.Systems cull résumés until, years later, we discover that they have inherent gender biases. Algorithms decide bail and parole?and appear to assess Black and White defendants differently. We can no longer assume that our mortgage application, or even our medical tests, will be seen by human eyes. And as autonomous vehicles share our streets, we are increasingly putting our lives in their hands.The mathematical and computational models driving these changes range in complexity from something that can fit on a spreadsheet to a complex system that might credibly be called “artificial intelligence.” They are steadily replacing both human judgment and explicitly programmed software.In best-selling author Brian Christian’s riveting account, we meet the alignment problem’s “first-responders,” and learn their ambitious plan to solve it before our hands are completely off the wheel. In a masterful blend of history and on-the ground reporting, Christian traces the explosive growth in the field of machine learning and surveys its current, sprawling frontier. Readers encounter a discipline finding its legs amid exhilarating and sometimes terrifying progress. Whether they—and we—succeed or fail in solving the alignment problem will be a defining human story.The Alignment Problem offers an unflinching reckoning with humanity’s biases and blind spots, our own unstated assumptions and often contradictory goals. A dazzlingly interdisciplinary work, it takes a hard look not only at our technology but at our culture—and finds a story by turns harrowing and hopeful.

    It can be microscopic, yet also accounts for the largest organisms ever recorded, living for millennia and weighing tens of thousands of tonnes. Its ability to digest rock enabled the first life on land, it can survive unprotected in space, and thrives amidst nuclear radiation.In this captivating adventure, Merlin Sheldrake explores the spectacular and neglected world of fungi: endlessly surprising organisms that sustain nearly all living systems. They can solve problems without a brain, stretching traditional definitions of ‘intelligence’, and can manipulate animal behaviour with devastating precision. In giving us bread, alcohol and life-saving medicines, fungi have shaped human history, and their psychedelic properties, which have influenced societies since antiquity, have recently been shown to alleviate a number of mental illnesses. The ability of fungi to digest plastic, explosives, pesticides and crude oil is being harnessed in break-through technologies, and the discovery that they connect plants in underground networks, the ‘Wood Wide Web’, is transforming the way we understand ecosystems. Yet they live their lives largely out of sight, and over ninety percent of their species remain undocumented.Entangled Life is a mind-altering journey into this hidden kingdom of life, and shows that fungi are key to understanding the planet on which we live, and the ways we think, feel and behave. The more we learn about fungi, the less makes sense without them.

    Today, nine out of ten Americans live in places at significant risk of earthquakes, hurricanes, tornadoes, terrorism, or other disasters. Tomorrow, some of us will have to make split-second choices to save ourselves and our families. How will we react? What will it feel like? Will we be heroes or victims? Will our upbringing, our gender, our personality–anything we’ve ever learned, thought, or dreamed of–ultimately matter?    Amanda Ripley, an award-winning journalist for Time magazine who has covered some of the most devastating disasters of our age, set out to discover what lies beyond fear and speculation. In this magnificent work of investigative journalism, Ripley retraces the human response to some of history’s epic disasters, from the explosion of the Mont Blanc munitions ship in 1917–one of the biggest explosions before the invention of the atomic bomb–to a plane crash in England in 1985 that mystified investigators for years, to the journeys of the 15,000 people who found their way out of the World Trade Center on September 11, 2001. Then, to understand the science behind the stories, Ripley turns to leading brain scientists, trauma psychologists, and other disaster experts, formal and informal, from a Holocaust survivor who studies heroism to a master gunfighter who learned to overcome the effects of extreme fear. Finally, Ripley steps into the dark corners of her own imagination, having her brain examined by military researchers and experiencing through realistic simulations what it might be like to survive a plane crash into the ocean or to escape a raging fire.     Ripley comes back with precious wisdom about the surprising humanity of crowds, the elegance of the brain’s fear circuits, and the stunning inadequacy of many of our evolutionary responses. Most unexpectedly, she discovers the brain’s ability to do much, much better, with just a little help.The Unthinkable escorts us into the bleakest regions of our nightmares, flicks on a flashlight, and takes a steady look around. Then it leads us home, smarter and stronger than we were before.

    A fast-paced, sure-to-astonish scientific adventure from “one of our finest science journalists” (Jonah Lehrer), Weiner’s Long for This World addresses the ageless question, “Is there a secret to eternal youth?” And has it, at long last, been found?
