    In The Triple Helix, Lewontin the scientist and Lewontin the critic come together to provide a concise, accessible account of what his work has taught him about biology and about its relevance to human affairs. In the process, he exposes some of the common and troubling misconceptions that misdirect and stall our understanding of biology and evolution.The central message of this book is that we will never fully understand living things if we continue to think of genes, organisms, and environments as separate entities, each with its distinct role to play in the history and operation of organic processes. Here Lewontin shows that an organism is a unique consequence of both genes and environment, of both internal and external features. Rejecting the notion that genes determine the organism, which then adapts to the environment, he explains that organisms, influenced in their development by their circumstances, in turn create, modify, and choose the environment in which they live.The Triple Helix is vintage Lewontin: brilliant, eloquent, passionate, and deeply critical. But it is neither a manifesto for a radical new methodology nor a brief for a new theory. It is instead a primer on the complexity of biological processes, a reminder to all of us that living things are never as simple as they may seem.

    The latest studies are revealing exciting new discoveries, such as how the DNA and related chemical compounds in our cells work together to direct the processes of life. Scientists are not only unraveling how life evolved in the ancient past, but are also finding the keys to creating a healthier future.  How does the minuscule chemical cluster in each of our 100 trillion cells accomplish the amazing feat of creating and maintaining our bodies? Frank Ryan, a physician and an evolutionary biologist, describes the complex ways in which the genome operates as a holistic system and not solely through genes coding for proteins—the building blocks of life. Also involved are elaborate switching mechanisms that regulate and control portions of our DNA, as well as the interplay of retroviruses and bacteria.This groundbreaking book explains that we are on the cusp of an amazing era of disease treatment and eradication.

    In the book, Sagan explores 15 billion years of cosmic evolution and the development of science and civilization. Cosmos traces the origins of knowledge and the scientific method, mixing science and philosophy, and speculates to the future of science. The book also discusses the underlying premises of science by providing biographical anecdotes about many prominent scientists throughout history, placing their contributions into the broader context of the development of modern science.The book covers a broad range of topics, comprising Sagan's reflections on anthropological, cosmological, biological, historical, and astronomical matters from antiquity to contemporary times. Sagan reiterates his position on extraterrestrial life—that the magnitude of the universe permits the existence of thousands of alien civilizations, but no credible evidence exists to demonstrate that such life has ever visited earth.

    Friedman, New York Times Big World, Small Planet probes the urgent predicament of our times: how is it possible to create a positive future for both humanity and Earth? We have entered the Anthropocene—the era of massive human impacts on the planet—and the actions of over seven billion residents threaten to destabilize Earth’s natural systems, with cascading consequences for human societies. In this extraordinary book, the authors combine the latest science with compelling storytelling and amazing photography to create a new narrative for humanity’s future. Johan Rockström and Mattias Klum reject the notion that economic growth and human prosperity can only be achieved at the expense of the environment. They contend that we have unprecedented opportunities to navigate a “good Anthropocene.” By embracing a deep mind-shift, humanity can reconnect to Earth, discover universal values, and take on the essential role of planetary steward. With eloquence and profound optimism, Rockström and Klum envision a future of abundance within planetary boundaries—a revolutionary future that is at once necessary, possible, and sustainable for coming generations.

    With such startling assertions, Hardin has cut a swathe through the field of ecology for decades, winning a reputation as a fearless and original thinker. A prominent biologist, ecological philosopher, and keen student of human population control, Hardin now offers the finest summation of his work to date, with an eloquent argument for accepting the limits of the earth's resources--and the hard choices we must make to live within them. In Living Within Limits, Hardin focuses on the neglected problem of overpopulation, making a forceful case for dramatically changing the way we live in and manage our world. Our world itself, he writes, is in the dilemma of the lifeboat: it can only hold a certain number of people before itsinks--not everyone can be saved. The old idea of progress and limitless growth misses the point that the earth (and each part of it) has a limited carrying capacity; sentimentality should not cloud our ability to take necessary steps to limit population. But Hardin refutes the notion that goodwilland voluntary restraints will be enough. Instead, nations where population is growing must suffer the consequences alone. Too often, he writes, we operate on the faulty principle of shared costs matched with private profits. In Hardin's famous essay, The Tragedy of the Commons, he showed how avillage common pasture suffers from overgrazing because each villager puts as many cattle on it as possible--since the costs of grazing are shared by everyone, but the profits go to the individual. The metaphor applies to global ecology, he argues, making a powerful case for closed borders and anend to immigration from poor nations to rich ones. The production of human beings is the result of very localized human actions; corrective action must be local....Globalizing the 'population problem' would only ensure that it would never be solved. Hardin does not shrink from the startlingimplications of his argument, as he criticizes the shipment of food to overpopulated regions and asserts that coercion in population control is inevitable. But he also proposes a free flow of information across boundaries, to allow each state to help itself. The time-honored practice of pollute and move on is no longer acceptable, Hardin tells us. We now fill the globe, and we have no where else to go. In this powerful book, one of our leading ecological philosophers points out the hard choices we must make--and the solutions we have beenafraid to consider.

    And before there were fish in the sea, there were cephalopods - the ancestors of modern squid and Earth’s first truly substantial animals. Cephalopods became the first creatures to rise from the seafloor, essentially inventing the act of swimming. With dozens of tentacles and formidable shells, they presided over an undersea empire for millions of years. But when fish evolved jaws, the ocean’s former top predator became its most delicious snack. Cephalopods had to step up their game. Many species streamlined their shells and added defensive spines, but these enhancements only provided a brief advantage. Some cephalopods then abandoned the shell entirely, which opened the gates to a flood of evolutionary innovations: masterful camouflage, fin-supplemented jet propulsion, perhaps even dolphin-like intelligence. Squid Empire is an epic adventure spanning hundreds of millions of years, from the marine life of the primordial ocean to the calamari on tonight’s menu. Anyone who enjoys the undersea world—along with all those obsessed with things prehistoric—will be interested in the sometimes enormous, often bizarre creatures that ruled the seas long before the first dinosaurs.

    Astrophysicist Adam Frank traces the question of alien life and intelligence from the ancient Greeks to the leading thinkers of our own time, and shows how we as a civilization can only hope to survive climate change if we recognize what science has recently discovered: that we are just one of ten billion trillion planets in the Universe, and it’s highly likely that many of those planets hosted technologically advanced alien civilizations. What’s more, each of those civilizations must have faced the same challenge of civilization-driven climate change.Written with great clarity and conviction, Light of the Stars builds on the inspiring work of pioneering scientists such as Frank Drake and Carl Sagan, whose work at the dawn of the space age began building the new science of astrobiology; Jack James, the Texas-born engineer who drove NASA’s first planetary missions to success; Vladimir Vernadsky, the Russian geochemist who first envisioned the Earth’s biosphere; and James Lovelock and Lynn Margulis, who invented Gaia theory. Frank recounts the perilous journey NASA undertook across millions of miles of deep space to get its probes to Venus and Mars, yielding our first view of the cosmic laws of planets and climate that changed our understanding of our place in the universe.Thrilling science at the grandest of scales, Light of the Stars explores what may be the largest question of all: What can the likely presence of life on other worlds tell us about our own fate?

    Her work has influenced filmmakers (the Tree of Souls of James Cameron's Avatar) and her TED talks have been viewed by more than 10 million people worldwide.Now, in her first book, Simard brings us into her world, the intimate world of the trees, in which she brilliantly illuminates the fascinating and vital truths--that trees are not simply the source of timber or pulp, but are a complex, interdependent circle of life; that forests are social, cooperative creatures connected through underground networks by which trees communicate their vitality and vulnerabilities with communal lives not that different from our own.Simard writes--in inspiring, illuminating, and accessible ways--how trees, living side by side for hundreds of years, have evolved, how they perceive one another, learn and adapt their behaviors, recognize neighbors, and remember the past; how they have agency about the future; elicit warnings and mount defenses, compete and cooperate with one another with sophistication, characteristics ascribed to human intelligence, traits that are the essence of civil societies--and at the center of it all, the Mother Trees: the mysterious, powerful forces that connect and sustain the others that surround them.Simard writes of her own life, born and raised into a logging world in the rainforests of British Columbia, of her days as a child spent cataloging the trees from the forest and how she came to love and respect them--embarking on a journey of discovery, and struggle. And as she writes of her scientific quest, she writes of her own journey--of love and loss, of observation and change, of risk and reward, making us understand how deeply human scientific inquiry exists beyond data and technology, that it is about understanding who we are and our place in the world, and, in writing of her own life, we come to see the true connectedness of the Mother Tree that nurtures the forest in the profound ways that families and human societies do, and how these inseparable bonds enable all our survival.

    Here are astounding animals of every stripe: Dung beetles that steer by the light of the Milky Way. Ants and bees that rely on patterns of light invisible to humans. Sea turtles and moths that find their way using Earth’s magnetic field. Humpback whales that swim thousands of miles while holding a rocksteady course. Birds that can locate their nests on a tiny island after crisscrossing an ocean.The age of viewing animals as unthinking drones is over. As Supernavigators makes clear, a stunning array of species command senses and skills—and arguably, types of intelligence—beyond our own. Weaving together interviews with leading animal behaviorists and the groundbreaking discoveries of Nobel Prize–winning scientists, David Barrie reveals these wonders in a whole new light.

    . . The essays in the collection [are] meditations that reveal not only how science actually happens but also who or what propels its immutable humanity.” — Maria Popova, Brain Pickings“A stimulating compendium.” — Kirkus ReviewsPulitzer Prize–winning journalist and author Deborah Blum selects the year’s top science and nature writing from writers who balance research with humanity and in the process uncover riveting stories of discovery across the disciplines.

    Even utility and oil companies now promote conservation in the face of demands for dwindling energy reserves. And for years some biologists have warned us of the direct correlation between scarcity and population growth. These scientists see an appalling future riding the tidal wave of a worldwide growth of population and technology.A calm but unflinching realist, Catton suggests that we cannot stop this wave - for we have already overshot the Earth's capacity to support so huge a load. He contradicts those scientists, engineers, and technocrats who continue to write optimistically about energy alternatives. Catton asserts that the technological panaceas proposed by those who would harvest from the seas, harness the winds, and farm the deserts are ignoring the fundamental premise that "the principals of ecology apply to all living things." These principles tell us that, within a finite system, economic expansion is not irreversible and population growth cannot continue indefinitely. If we disregard these facts, our sagging American Dream will soon shatter completely.

    But they are under threat as never before, and their problems are spreading across the continent. The Death and Life of the Great Lakes is prize-winning reporter Dan Egan’s compulsively readable portrait of an ecological catastrophe happening right before our eyes, blending the epic story of the lakes with an examination of the perils they face and the ways we can restore and preserve them for generations to come.

    The earthworm may be small, spineless, and blind, but its impact on the ecosystem is profound. It ploughs the soil, fights plant diseases, cleans up pollution, and turns ordinary dirt into fertile land. Who knew? In her witty, offbeat style, Stewart shows that much depends on the actions of the lowly worm. Charles Darwin devoted his last years to the meticulous study of these creatures, praising their remarkable abilities. With the august scientist as her inspiration, Stewart investigates the worm's subterranean realm, talks to oligochaetologists—the unsung heroes of earthworm science—who have devoted their lives to unearthing the complex life beneath our feet, and observes the thousands of worms in her own garden. From the legendary giant Australian worm that stretches to ten feet in length to the modest nightcrawler that wormed its way into the heart of Darwin's last book to the energetic red wigglers in Stewart's compost bin, The Earth Moved gives worms their due and exposes their hidden and extraordinary universe. This book is for all of us who appreciate Mother Nature's creatures, no matter how humble.

    But all too often the full picture of change is obstructed by dense data sets and particular catastrophes. Struggling with this obscurity in her role as an editor at Nature, Gaia Vince decided to travel the world and see for herself what life is really like for people on the frontline of this new reality. What she found was a number people doing the most extraordinary things.During her journey she finds a man who is making artificial glaciers in Nepal along with an individual who is painting mountains white to attract snowfall; take the electrified reefs of the Maldives; or the man who's making islands out of rubbish in the Caribbean. These are ordinary people who are solving severe crises in crazy, ingenious, effective ways. While Vince does not mince words regarding the challenging position our species is in, these wonderful stories, combined with the new science that underpins Gaia's expertise and research, make for a persuasive, illuminating — and strangely hopeful — read on what the Anthropocene means for our future.
