But in the modern world, the breast is changing. Breasts are getting bigger, arriving earlier, and attracting newfangled chemicals. Increasingly, the odds are stacked against us in the struggle with breast cancer, even among men. What makes breasts so mercurial—and so vulnerable?In this informative and highly entertaining account, intrepid science reporter Florence Williams sets out to uncover the latest scientific findings from the fields of anthropology, biology, and medicine. Her investigation follows the life cycle of the breast from puberty to pregnancy to menopause, taking her from a plastic surgeon’s office where she learns about the importance of cup size in Texas to the laboratory where she discovers the presence of environmental toxins in her own breast milk. The result is a fascinating exploration of where breasts came from, where they have ended up, and what we can do to save them.

    Stringer's new theory, based on archeological and genetic evidence, holds that distinct humans coexisted and competed across the African continent—exchanging genes, tools, and behavioral strategies.Stringer draws on analyses of old and new fossils from around the world, DNA studies of Neanderthals (using the full genome map) and other species, and recent archeological digs to unveil his new theory. He shows how the most sensational recent fossil findings fit with his model, and he questions previous concepts (including his own) of modernity and how it evolved.Lone Survivors will be the definitive account of who and what we were, and will change perceptions about our origins and about what it means to be human.

    Yet something about our species distinguished it from the pack, and ultimately led to its survival while the rest became extinct. Just what was it that allowed Homo sapiens to become masters of the planet? Ian Tattersall, curator emeritus at the American Museum of Natural History, takes us deep into the fossil record to uncover what made humans so special. Surveying a vast field from initial bipedality to language and intelligence, Tattersall argues that Homo sapiens acquired a winning combination of traits that was not the result of long-term evolutionary refinement. Instead, the final result emerged quickly, shocking our world and changing it forever.

    The pages take the reader on a wild narrative ride through the world of squid science and adventure, along the way addressing some riddles about what intelligence is, and what monsters lie in the deep. In addition to squid, both giant and otherwise, Kraken examines other equally enthralling cephalopods, including the octopus and the cuttlefish, and explores their otherworldly abilities, such as camouflage and bioluminescence. Accessible and entertaining, Kraken is also the first substantial volume on the subject in more than a decade and a must for fans of popular science.

    His genius as an essayist lies in his unmatched ability to use his knowledge of the world, including popular culture, to illuminate the realm of science.Ever Since Darwin, Stephen Jay Gould's first book, has sold more than a quarter of a million copies. Like all succeeding collections by this unique writer, it brings the art of the scientific essay to unparalleled heights.

    Weaving together the cosmos' history and our own in an expanding intellectual adventure story, Dark Matter and the Dinosaurs takes us from the mysteries of dark matter and our cosmic environment to the conditions for life on Earth.Sixty-six million years ago, an object the size of a city descended from space to crash into Earth, creating a cataclysm that killed off the dinosaurs, along with three-quarters of the other species on the planet. What was its origin? Randall proposes it was a comet that was dislodged from its orbit as the Solar System passed through a disk of dark matter that is embedded in the plane of the Milky Way. Her research challenges the usual assumptions about the simple nature of dark matter and demonstrates how scientists formulate and establish new ideas. In a sense, it might have been dark matter that killed the dinosaurs.With her unique and wide-ranging perspective, Randall connects dark matter to the history of the world in the broadest terms. Bringing in pop culture and social and political viewpoints, she shares with us the latest findings—established and speculative—regarding dark matter, the cosmos, the galaxy, asteroids, comets, and impacts, as well as life's development and extinctions. Randall makes clear how connected the planet is to the makeup of the Universe, but also how fragile our place in the Universe, which evolved over billions of years, might be.In this brilliant and fresh exploration of our cosmic environment, Professor Randall explains the underlying science of our world in the breathtaking tale of a Universe in which the small and the large, the visible and the hidden are intimately related. Dark Matter and the Dinosaurs illuminates the deep relationships that are critical to our world as well as the astonishing beauty of the structures and connections that surround us. It's impossible to read this book and look at either Earth or sky again in the same way.

    Two scientists explore the potential of a revolutionary genetics technology capable of easily and affordably manipulating DNA in human embryos to prevent specific diseases, addressing key concerns about related ethical and societal repercussions.

    In his groundbreaking Before the Dawn, Wade reveals humanity's origins as never before--a journey made possible only recently by genetic science, whose incredible findings have answered such questions as: What was the first human language like? How large were the first societies, and how warlike were they? When did our ancestors first leave Africa, and by what route did they leave? By eloquently solving these and numerous other mysteries, Wade offers nothing less than a uniquely complete retelling of a story that began 500 centuries ago.

    Drawing on momentous (yet dimly remembered) historical epidemics, contemporary analyses, and cutting-edge research from a range of scientific disciplines, bestselling author, physician, sociologist, and public health expert Nicholas A. Christakis explores what it means to live in a time of plague—an experience that is paradoxically uncommon to the vast majority of humans who are alive, yet deeply fundamental to our species.Unleashing new divisions in our society as well as opportunities for cooperation, this 21st-century pandemic has upended our lives in ways that will test, but not vanquish, our already frayed collective culture. Featuring new, provocative arguments and vivid examples ranging across medicine, history, sociology, epidemiology, data science, and genetics, Apollo's Arrow envisions what happens when the great force of a deadly germ meets the enduring reality of our evolved social nature.

    To the right listener, they tell us all about themselves: where they came from, how they lived, how they died - and who killed them. Forensic scientists can unlock the mysteries of the past and help justice to be done using the messages left by a corpse, a crime scene or the faintest of human traces. Forensics uncovers the secrets of forensic medicine, drawing on interviews with top-level professionals, ground-breaking research and Val McDermid's own experience to lay bare the secrets of this fascinating science. And, along the way, she wonders at how maggots collected from a corpse can help determine time of death, how a DNA trace a millionth the size of a grain of salt can be used to convict a killer and how a team of young Argentine scientists led by a maverick American anthropologist uncovered the victims of a genocide.In her crime novels, Val McDermid has been solving complex crimes and confronting unimaginable evil for years. Now, she's looking at the people who do it for real, and real crime scenes. It's a journey that will take her to war zones, fire scenes and autopsy suites, and bring her into contact with extraordinary bravery and wickedness, as she traces the history of forensics from its earliest beginnings to the cutting-edge science of the modern day.

    Jane Goodall was a young secretarial school graduate when the legendary Louis Leakey chose her to undertake a landmark study of chimpanzees in the world. This paperback edition contains 80 photographs and in introduction by Stephen Jay Gould.

    Every year, faced with the life-or-death problem of choosing and traveling to a new home, honeybees stake everything on a process that includes collective fact-finding, vigorous debate, and consensus building. In fact, as world-renowned animal behaviorist Thomas Seeley reveals, these incredible insects have much to teach us when it comes to collective wisdom and effective decision making. A remarkable and richly illustrated account of scientific discovery, Honeybee Democracy brings together, for the first time, decades of Seeley's pioneering research to tell the amazing story of house hunting and democratic debate among the honeybees.In the late spring and early summer, as a bee colony becomes overcrowded, a third of the hive stays behind and rears a new queen, while a swarm of thousands departs with the old queen to produce a daughter colony. Seeley describes how these bees evaluate potential nest sites, advertise their discoveries to one another, engage in open deliberation, choose a final site, and navigate together--as a swirling cloud of bees--to their new home. Seeley investigates how evolution has honed the decision-making methods of honeybees over millions of years, and he considers similarities between the ways that bee swarms and primate brains process information. He concludes that what works well for bees can also work well for people: any decision-making group should consist of individuals with shared interests and mutual respect, a leader's influence should be minimized, debate should be relied upon, diverse solutions should be sought, and the majority should be counted on for a dependable resolution.An impressive exploration of animal behavior, Honeybee Democracy shows that decision-making groups, whether honeybee or human, can be smarter than even the smartest individuals in them.

    Vast fortunes have been built on the backs of sheep, and cities shaped by shepherds' markets and meat trading.Sally Coulthard weaves the rich and fascinating story of sheep into a vivid and colourful tapestry, brimful of engaging anecdotes and remarkable ovine facts, whose multiple strands reflect the deep penetration of these woolly animals into every aspect of human society and culture.

    A story of defiance and determination by a controversial scientist, this is Lee Berger's own take on finding Homo naledi, an all-new species on the human family tree and one of the greatest discoveries of the 21st century.In 2013, Berger, a National Geographic Explorer-in-Residence, caught wind of a cache of bones in a hard-to-reach underground cave in South Africa. He put out a call around the world for petite collaborators--men and women small and adventurous enough to be able to squeeze through 8-inch tunnels to reach a sunless cave 40 feet underground. With this team of "underground astronauts," Berger made the discovery of a lifetime: hundreds of prehistoric bones, including entire skeletons of at least 15 individuals, all perhaps two million years old. Their features combined those of known prehominids like Lucy, the famous Australopithecus, with those more human than anything ever before seen in prehistoric remains. Berger's team had discovered an all new species, and they called it Homo naledi.The cave quickly proved to be the richest primitive hominid site ever discovered, full of implications that shake the very foundation of how we define what makes us human. Did this species come before, during, or after the emergence of Homo sapiens on our evolutionary tree? How did the cave come to contain nothing but the remains of these individuals? Did they bury their dead? If so, they must have had a level of self-knowledge, including an awareness of death. And yet those are the very characteristics used to define what makes us human. Did an equally advanced species inhabit Earth with us, or before us? Berger does not hesitate to address all these questions.Berger is a charming and controversial figure, and some colleagues question his interpretation of this and other finds. But in these pages, this charismatic and visionary paleontologist counters their arguments and tells his personal story: a rich and readable narrative about science, exploration, and what it means to be human.

    This was the world of medicine when Thomas Dent Mütter began his trailblazing career as a plastic surgeon in Philadelphia during the middle of the nineteenth century.Although he died at just forty-eight, Mütter was an audacious medical innovator who pioneered the use of ether as anesthesia, the sterilization of surgical tools, and a compassion-based vision for helping the severely deformed, which clashed spectacularly with the sentiments of his time.   Brilliant, outspoken, and brazenly handsome, Mütter was flamboyant in every aspect of his life. He wore pink silk suits to perform surgery, added an umlaut to his last name just because he could, and amassed an immense collection of medical oddities that would later form the basis of Philadelphia’s Mütter Museum. Cristin O’Keefe Aptowicz chronicles how Mütter’s efforts helped establish Philadelphia as a global mecca for medical innovation—despite intense resistance from his numerous rivals.
