Someday, we know, we will all die. And, we know, so too will the universe itself.Until the End of Time is Brian Greene's breathtaking new exploration of the cosmos and our quest to understand it. Greene takes us on a journey across time, from our most refined understanding of the universe's beginning, to the closest science can take us to the very end. He explores how life and mind emerged from the initial chaos, and how our minds, in coming to understand their own impermanence, seek in different ways to give meaning to experience: in story, myth, religion, creative expression, science, the quest for truth, and our longing for the timeless, or eternal. Through a series of nested stories that explain distinct but interwoven layers of reality-from the quantum mechanics to consciousness to black holes-Greene provides us with a clearer sense of how we came to be, a finer picture of where we are now, and a firmer understanding of where we are headed.Yet all this understanding, which arose with the emergence of life, will dissolve with its conclusion. Which leaves us with one realization: during our brief moment in the sun, we are tasked with the charge of finding our own meaning.Let us embark.

    It intersects with Darwin’s theory of evolution, and collides with the horrors of Nazi eugenics in the 1940s. The gene transforms post-war biology. It reorganizes our understanding of sexuality, temperament, choice and free will. This is a story driven by human ingenuity and obsessive minds – from Charles Darwin and Gregor Mendel to Francis Crick, James Watson and Rosalind Franklin, and the thousands of scientists still working to understand the code of codes.This is an epic, moving history of a scientific idea coming to life, by the author of The Emperor of All Maladies. But woven through The Gene, like a red line, is also an intimate history – the story of Mukherjee’s own family and its recurring pattern of mental illness, reminding us that genetics is vitally relevant to everyday lives. These concerns reverberate even more urgently today as we learn to “read” and “write” the human genome – unleashing the potential to change the fates and identities of our children.Majestic in its ambition, and unflinching in its honesty, The Gene gives us a definitive account of the fundamental unit of heredity – and a vision of both humanity’s past and future.

    Poisons permeate our world. They are in the environment, the workplace, the home. They are in food, our favorite whiskey, medicine, well water. They have been used to cure disease as well as to incapacitate and kill. They smooth wrinkles, block pain, stimulate, and enhance athletic ability. In this entertaining and fact-filled book, science writer Peter Macinnis considers poisons in all their aspects. He recounts stories of the celebrated poisoners in history and literature, from Nero to Thomas Wainewright, and from the death of Socrates to Hamlet and Peter Pan. He discusses the sources of various poisons-from cyanide to strychnine, from Botox to ricin and Sarin gas-as well as their detection. Then he analyzes the science of their action in the body and their uses in medicine, cosmetics, war, and terrorism. With wit and precision, he weighs such questions as: Was Lincoln's volatility caused by mercury poisoning? Was Jack the Ripper an arsenic eater? Can wallpaper kill? For anyone who has ever wondered and been afraid to ask, here is a rich miscellany for your secret questions about toxins.

    In these accounts, written with sensitivity as cautionary tales about what to do and what not to do in one of our wildest national parks, Whittlesey recounts deaths ranging from tragedy to folly—from being caught in a freak avalanche to the goring of a photographer who just got a little too close to a bison. Armchair travelers and park visitors alike will be fascinated by this important book detailing the dangers awaiting in our first national park.

    The book documents the adverse environmental effects caused by the indiscriminate use of pesticides. Carson accused the chemical industry of spreading disinformation, and public officials of accepting the industry's marketing claims unquestioningly.The book appeared in September 1962 and the outcry that followed its publication forced the banning of DDT and spurred revolutionary changes in the laws affecting our air, land, and water. Carson’s book was instrumental in launching the environmental movement.

    Angier takes readers on a mesmerizing tour of female anatomy and physiology that explores everything from organs to orgasm, and delves into topics such as exercise, menopause, and the mysterious properties of breast milk.A self-proclaimed "scientific fantasia of womanhood." Woman ultimately challenges widely accepted Darwinian-based gender stereotypes. Angier shows how cultural biases have influenced research in evolutionary psychology (the study of the biological bases of behavior) and consequently led to dubious conclusions about "female nature." such as the idea that women are innately monogamous while men are natural philanderers.But Angier doesn't just point fingers; she offers optimistic alternatives and transcends feminist polemics with an enlightened subversiveness that makes for a joyful, fresh vision of womanhood. Woman is a seminal work that will endure as an essential read for anyone intersted in how biology affects who we are as women, as men, and as human beings.

    What is going on inside the head of a nightingale as it sings, and how does its brain improvise? How do desert birds detect rain hundreds of kilometers away? How do birds navigate by using an innate magnetic compass?Tracing the history of how our knowledge about birds has grown, particularly through advances in technology over the past fifty years, Bird Sense tells captivating stories about how birds interact with one another and their environment. More advanced testing methods have debunked previously held beliefs, such as female starlings selecting mates based on how symmetrical the male's plumage markings are. (Whereas females can discern the difference between symmetrical and asymmetrical markings, they are not very good at detecting small differences among symmetrically marked males!)Never before has there been a popular book about how intricately bird behavior is shaped by birds' senses. A lifetime spent studying birds has provided Tim Birkhead with a wealth of fieldwork experiences, insights, and a unique understanding of birds, all firmly grounded in science. No one who reads Bird Sense can fail to be dazzled by it.

    Few people know bears as intimately as Else Poulsen. She has raised bears, comforted bears, taught bears, learned from bears, had bears communicate their needs to her, and nursed bears back to health. This remarkable book reveals the many insights about bears and their lives that she has gained through her work with them. In the eighties, Poulsen became a zookeeper in Calgary, where she rehabilitated bears in crisis. She has shared in the joy of a polar bear discovering soil under her paws for the first time in twenty years, felt the pride of a cub learning to crack nuts with her molars, and grieved at the horror of captivity for Asian black bears in China.Smiling Bears provides an enlightening and moving portrait of bears in all their richness and complexity and of Poulsen's exhilarating work with them. Also available in paperback.

    Harvey Washington Wiley, who fought for change.By the end of nineteenth century, food was dangerous. Lethal, even. "Milk" might contain formaldehyde, most often used to embalm corpses. Decaying meat was preserved with both salicylic acid, a pharmaceutical chemical, and borax, a compound first identified as a cleaning product. This was not by accident; food manufacturers had rushed to embrace the rise of industrial chemistry, and were knowingly selling harmful products. Unchecked by government regulation, basic safety, or even labelling requirements, they put profit before the health of their customers. By some estimates, in New York City alone, thousands of children were killed by "embalmed milk" every year. Citizens--activists, journalists, scientists, and women's groups--began agitating for change. But even as protective measures were enacted in Europe, American corporations blocked even modest regulations. Then, in 1883, Dr. Harvey Washington Wiley, a chemistry professor from Purdue University, was named chief chemist of the agriculture department, and the agency began methodically investigating food and drink fraud, even conducting shocking human tests on groups of young men who came to be known as, "The Poison Squad."Over the next thirty years, a titanic struggle took place, with the courageous and fascinating Dr. Wiley campaigning indefatigably for food safety and consumer protection. Together with a gallant cast, including the muckraking reporter Upton Sinclair, whose fiction revealed the horrific truth about the Chicago stockyards; Fannie Farmer, then the most famous cookbook author in the country; and Henry J. Heinz, one of the few food producers who actively advocated for pure food, Dr. Wiley changed history. When the landmark 1906 Food and Drug Act was finally passed, it was known across the land, as "Dr. Wiley's Law."Blum brings to life this timeless and hugely satisfying "David and Goliath" tale with righteous verve and style, driving home the moral imperative of confronting corporate greed and government corruption with a bracing clarity, which speaks resoundingly to the enormous social and political challenges we face today.

    But do those of us who accept the reality of human-caused climate change truly believe it? If we did, surely we would be roused to act on what we know. Will future generations distinguish between those who didn’t believe in the science of global warming and those who said they accepted the science but failed to change their lives in response?In We Are the Weather, Jonathan Safran Foer explores the central global dilemma of our time in a surprising, deeply personal, and urgent new way. The task of saving the planet will involve a great reckoning with ourselves—with our all-too-human reluctance to sacrifice immediate comfort for the sake of the future. We have, he reveals, turned our planet into a farm for growing animal products, and the consequences are catastrophic. Only collective action will save our home and way of life. And it all starts with what we eat—and don’t eat—for breakfast.

    . . No scientist had seen a Blakiston’s fish owl so far south in a hundred years . . . When he was just a fledgling birdwatcher, Jonathan C. Slaght had a chance encounter with one of the most mysterious birds on Earth. Bigger than any owl he knew, it looked like a small bear with decorative feathers. He snapped a quick photo and shared it with experts. Soon he was on a five-year journey, searching for this enormous, enigmatic creature in the lush, remote forests of eastern Russia. That first sighting set his calling as a scientist.Despite a wingspan of six feet and a height of over two feet, the Blakiston’s fish owl is highly elusive. They are easiest to find in winter, when their tracks mark the snowy banks of the rivers where they feed. They are also endangered. And so, as Slaght and his devoted team set out to locate the owls, they aim to craft a conservation plan that helps ensure the species’ survival. This quest sends them on all-night monitoring missions in freezing tents, mad dashes across thawing rivers, and free-climbs up rotting trees to check nests for precious eggs. They use cutting-edge tracking technology and improvise ingenious traps. And all along, they must keep watch against a run-in with a bear or an Amur tiger. At the heart of Slaght’s story are the fish owls themselves: cunning hunters, devoted parents, singers of eerie duets, and survivors in a harsh and shrinking habitat.Through this rare glimpse into the everyday life of a field scientist and conservationist, Owls of the Eastern Ice testifies to the determination and creativity essential to scientific advancement and serves as a powerful reminder of the beauty, strength, and vulnerability of the natural world.
