In this magisterial book, Hans Belting traces the longhistory of the sacral image and its changing role in European culture.Likeness and Presence looks at the beliefs, superstitions, hopes,and fears that come into play as people handle and respond to sacredimages, and presents a compelling interpretation of the place of theimage in Western history."A rarity within its genre—an art-historical analysis of iconographywhich is itself iconoclastic. . . . One of the most intellectuallyexciting and historically grounded interpretations of Christianiconography." —Graham Howes, Times Literary Supplement"Likeness and Presence offers the best source to survey the facts ofwhat European Christians put in their churches. . . . An impressivelydetailed contextual analysis of medieval objects." —Robin Cormack,New York Times Book Review"I cannot begin to describe the richness or the imaginative grandeur ofHans Belting's book. . . . It is a work that anyone interested in art,or in the history of thought about art, should regard as urgent reading.It is a tremendous achievement."—Arthur C. Danto, New Republic

    Indeed, these tiny structures inside our cells are important beyond imagining. Without mitochondria, we would have no cell suicide, no sculpting of embryonic shape, no sexes, no menopause, no aging.In this fascinating and thought-provoking book, Nick Lane brings together the latest research in this exciting field to show how our growing insight into mitochondria has shed light on how complex life evolved, why sex arose (why don't we just bud?), and why we age and die. These findings are of fundamental importance, both in understanding life on Earth, but also in controlling our own illnesses, and delaying our degeneration and death. Readers learn that two billion years ago, mitochondria were probably bacteria living independent lives and that their capture within larger cells was a turning point in the evolution of life, enabling the development of complex organisms. Lane describes how mitochondria have their own DNA and that its genes mutate much faster than those in the nucleus. This high mutation rate lies behind our aging and certain congenital diseases. The latest research suggests that mitochondria play a key role in degenerative diseases such as cancer. We also discover that mitochondrial DNA is passed down almost exclusively via the female line. That's why it has been used by some researchers to trace human ancestry daughter-to-mother, to "Mitochondrial Eve," giving us vital information about our evolutionary history.Written by Nick Lane, a rising star in popular science, Power, Sex, Suicide is the first book for general readers on the nature and function of these tiny, yet fascinating structures.

    After 3.8 billion years humankind is about to start evolving by new rules...From leading geopolitical expert and technology futurist Jamie Metzl comes a groundbreaking exploration of the many ways genetic-engineering is shaking the core foundations of our lives -- sex, war, love, and death.At the dawn of the genetics revolution, our DNA is becoming as readable, writable, and hackable as our information technology. But as humanity starts retooling our own genetic code, the choices we make today will be the difference between realizing breathtaking advances in human well-being and descending into a dangerous and potentially deadly genetic arms race.Enter the laboratories where scientists are turning science fiction into reality. Look towards a future where our deepest beliefs, morals, religions, and politics are challenged like never before and the very essence of what it means to be human is at play. When we can engineer our future children, massively extend our lifespans, build life from scratch, and recreate the plant and animal world, should we?

    As young women and boys were abducted, raped, and murdered, residents of the area held their loved ones closer and closer, terrified of the monster -- or monsters -- stalking the streets. Homicide detective Dennis Alsop began hunting the killer in the 1960s, and he didn't stop searching until his death 30 years later. For decades, detectives, actual and armchair, and the victims' families and friends continued to ask questions: Who was the Forest City Killer? Was there more than one person? Or did a depraved individual commit all of these crimes on his own?Combing through the files Detective Alsop left behind, researcher Vanessa Brown reopens the cases, revealing previously unpublished witness statements, details of evidence, and astonishing revelations about how this serial killer got away. And through her investigation, Vanessa discovers the unthinkable: like the notorious Golden State Killer, the Forest City Killer is still alive . . . and a simple DNA test could bring him to justice.

    In Never Home Alone, biologist Rob Dunn introduces us to the nearly 200,000 species living with us in our own homes, from the Egyptian meal moths in our cupboards and camel crickets in our basements to the lactobacillus lounging on our kitchen counters. You are not alone. Yet, as we obsess over sterilizing our homes and separating our spaces from nature, we are unwittingly cultivating an entirely new playground for evolution. These changes are reshaping the organisms that live with us -- prompting some to become more dangerous, while undermining those species that benefit our bodies or help us keep more threatening organisms at bay. No one who reads this engrossing, revelatory book will look at their homes in the same way again.

    . . A tour de force of a book that begs to be seen as well as to be read."--The Washington Post Book WorldWorld renowned scientist Carl Sagan and acclaimed author Ann Druyan have written a Roots for the human species, a lucid and riveting account of how humans got to be the way we are. Shadows of Forgotten Ancestors is a thrilling saga that starts with the origin of the Earth. It shows with humor and drama that many of our key traits--self-awareness, technology, family ties, submission to authority, hatred for those a little different from ourselves, reason, and ethics--are rooted in the deep past, and illuminated by our kinship with other animals.Sagan and Druyan conduct a breathtaking journey through space and time, zeroing in on critical turning points in evolutionary history, and tracing the origins of sex, altruism, violence, rape, and dominance. Their book culminates in a stunningly original examination of the connection between primate and human traits. Astonishing in its scope, brilliant in its insights, and an absolutely compelling read, Shadows of Forgotten Ancestors is a triumph of popular science.

    Using the latest genetic and anthropological data, Spencer Wells demonstrates that although humankind's decision to control our own food supply is what propelled us into the modern world, it had many downsides that we're just now beginning to recognize.

    Approaching the subject from a variety of perspectives: evolutionary, ecological, and cultural, this examination shows how integral excrement is to biodiversity, agriculture, public health, food production and distribution, and global ecosystems.From primordial ooze, dung beetles, bug frass, cat scats, and flush toilets to global trade, pandemics, and energy. This is the awesome, troubled, uncensored story of feces.

    Buried there lie answers about the origins of humankind. After a century of investigation, scientists have transformed our understanding about the beginnings of human life. But vital clues still remain hidden. In Born in Africa, Martin Meredith follows the trail of discoveries about human origins made by scientists over the last hundred years, recounting their intense rivalry, personal feuds, and fierce controversies as well as their feats of skill and endurance.The results have been momentous. Scientists have identified more than twenty species of extinct humans. They have firmly established Africa as the birthplace not only of humankind but also of modern humans. They have revealed how early technology, language ability, and artistic endeavour all originated in Africa; and they have shown how small groups of Africans spread out from Africa in an exodus sixty thousand years ago to populate the rest of the world. We have all inherited an African past.

    In The Missing Lynx, Ross Barnett uses case studies, new fossil discoveries, biomolecular evidence and more to paint pictures of these extinct species, and to explore the significance of the lynx's disappearance in ecological terms. He also discusses how the Britons that these animals shared their home with might have viewed them, and why some survived while others vanished.Barnett also looks in detail and the realistic potential of reintroductions and even of resurrection--topics that capture public interest today. With Beaver now wild again in various parts of Britain and even Great Bustard on Salisbury Plain, what about the return of sabretooths, mammoths, and the aurochs to modern ecosystems? Will we ever be able to bring these animals back? And should we?At a time where rewilding is moving from pie-in-the-sky to actual reality, this timely and important book looks from a scientific perspective at the magnificent megafauna we've lost, why we lost it and what happened as a result, and how we might realistically turn the ecological tide.

    Whether they are the devices of alien interlopers or more mundane weather phenomena, they have spawned a legacy of government inquiries, secretive societies, and countless dedicated investigators. We call them “Unidentified Flying Objects,” and they have claimed a prominent position in popular culture, enduring in part thanks to the legacy of researchers and persistently peculiar mysteries.

    Improper use of antibiotics. Local warfare. Massive refugee migration. Changing social and environmental conditions around the world have fostered the spread of new and potentially devastating viruses and diseases—HIV, Lassa, Ebola, and others. Laurie Garrett takes you on a fifty-year journey through the world's battles with microbes and examines the worldwide conditions that have culminated in recurrent outbreaks of newly discovered diseases, epidemics of diseases migrating to new areas, and mutated old diseases that are no longer curable. She argues that it is not too late to take action to prevent the further onslaught of viruses and microbes, and offers possible solutions for a healthier future.

    How they got here, persevered, and ultimately thrived is a story that resonates from the Pleistocene to our modern era. The lower sea levels of the Ice Age exposed a vast land bridge between Asia and North America, but the land bridge was not the only way across. Different people arrived from different directions, and not all at the same time.The first explorers of the New World were few, their encampments fleeting. The continent they reached had no people but was inhabited by megafauna--mastodons, giant bears, mammoths, saber-toothed cats, five-hundred-pound panthers, enormous bison, and sloths that stood one story tall. The first people were hunters--Paleolithic spear points are still encrusted with the proteins of their prey--but they were wildly outnumbered and many would themselves have been prey to the much larger animals.Atlas of a Lost World chronicles the last millennia of the Ice Age, the violent oscillations and retreat of glaciers, the clues and traces that document the first encounters of early humans, and the animals whose presence governed the humans' chances for survival. A blend of science and personal narrative reveals how much has changed since the time of mammoth hunters, and how little. Across unexplored landscapes yet to be peopled, readers will see the Ice Age, and their own age, in a whole new light.

    But who were the early speakers of this ancient mother tongue, and how did they manage to spread it around the globe? Until now their identity has remained a tantalizing mystery to linguists, archaeologists, and even Nazis seeking the roots of the Aryan race. The Horse, the Wheel, and Language lifts the veil that has long shrouded these original Indo-European speakers, and reveals how their domestication of horses and use of the wheel spread language and transformed civilization.Linking prehistoric archaeological remains with the development of language, David Anthony identifies the prehistoric peoples of central Eurasia's steppe grasslands as the original speakers of Proto-Indo-European, and shows how their innovative use of the ox wagon, horseback riding, and the warrior's chariot turned the Eurasian steppes into a thriving transcontinental corridor of communication, commerce, and cultural exchange. He explains how they spread their traditions and gave rise to important advances in copper mining, warfare, and patron-client political institutions, thereby ushering in an era of vibrant social change. Anthony also describes his fascinating discovery of how the wear from bits on ancient horse teeth reveals the origins of horseback riding.The Horse, the Wheel, and Language solves a puzzle that has vexed scholars for two centuries--the source of the Indo-European languages and English--and recovers a magnificent and influential civilization from the past.

    Can a person think herself to orgasm? Why doesn't Viagra help women-or, for that matter, pandas? Can a dead man get an erection? Is vaginal orgasm a myth? Mary Roach shows us how and why sexual arousal and orgasm-two of the most complex, delightful, and amazing scientific phenomena on earth-can be so hard to achieve and what science is doing to make the bedroom a more satisfying place.
