Krause is a pioneer in the revolutionary new science of archaeogenetics, archaeology augmented by revolutionary DNA sequencing technology, which has allowed scientists to uncover a new version of human history reaching back more than 100,000 years. Using this technology to re-examine human bones from the distant past, Krause has been able to map not only the genetic profiles of the dead, but also their ancient journeys.In this concise narrative he tells us their long-forgotten stories of migration and intersection. It's well known that many human populations carry genetic material from Neanderthals; but, as Krause and his colleagues discovered, we also share DNA with a newly uncovered human form, the Denisovans. We know now that a wave of farmers from Anatolia migrated into Europe 8,000 years ago, essentially displacing the dark-skinned, blue-eyed hunter-gatherers who preceded them. The farmer DNA is one of the core genetic components of contemporary Europeans and European Americans. Though the first people to cross into North and South America have long been assumed to be primarily of East Asian descent, we now know that they also share DNA with contemporary Europeans and European Americans. Genetics has an unfortunate history of smuggling in racist ideologies, but our most cutting-edge science tells us that genetic categories in no way reflect national borders.Krause vividly introduces us to prehistoric cultures such as the Aurignacians, innovative artisans who carved animals, people, and even flutes from bird bones more than 40,000 years ago; the Varna, who buried their loved ones with gold long before the Pharaohs of Egypt; and the Gravettians, big-game hunters who were Europe's most successful early settlers until they perished in the ice age. This informed retelling of the human epic confirms that immigration and genetic mingling have always defined our species and that who we are is a question of culture not genetics.

    In some cases, this absence can be dangerous, but in others it can simply mean a different way of seeing the world.In The Science of Evil Simon Baron-Cohen, an award-winning British researcher who has investigated psychology and autism for decades, develops a new brain-based theory of human cruelty. A true psychologist, however, he examines social and environmental factors that can erode empathy, including neglect and abuse.Based largely on Baron-Cohen's own research, The Science of Evil will change the way we understand and treat human cruelty.

    Snyder exposes the political passions, religious impulses, friendships, rivalries, and love of knowledge—and power—that drove these extraordinary men.  Whewell (who not only invented the word “scientist,” but also founded the fields of crystallography, mathematical economics, and the science of tides), Babbage (a mathematical genius who invented the modern computer), Herschel (who mapped the skies of the Southern Hemisphere and contributed to the invention of photography), and Jones (a curate who shaped the science of economics) were at the vanguard of the modernization of science.  This absorbing narrative of people, science and ideas  chronicles the intellectual revolution inaugurated by these men, one that continues to mold our understanding of the world around us and of our place within it.  Drawing upon the voluminous correspondence between the four men over the fifty years of their work, Laura J. Snyder shows how friendship worked to spur the men on to greater accomplishments, and how it enabled them to transform science and help create the modern world.

    Confusing messages from health authorities and ineffective treatments have left many people desperate for reliable solutions. An enormous alternative industry is filling the void, selling products that are often of questionable safety and totally unknown effectiveness.In Clean, doctor and journalist James Hamblin explores how we got here, examining the science and culture of how we care for our skin today. He talks to dermatologists, microbiologists, allergists, immunologists, aestheticians, bar-soap enthusiasts, venture capitalists, Amish people, theologians, and straight-up scam artists, trying to figure out what it really means to be clean. He even experiments with giving up showers entirely, and discovers that he is not alone.Along the way he realizes that most of our standards of cleanliness are less related to health than most people think. A major part of the picture has been missing: a little-known ecosystem known as the skin microbiome--the trillions of microbes that live on our skin and in our pores. These microbes are not dangerous; they're more like an outer layer of skin that no one knew we had, and they influence everything from acne, eczema, and dry skin to how we smell. The new goal of skin care will be to cultivate a healthy biome--and to embrace the meaning of "clean" in the natural sense. This can mean doing much less, saving time, money, energy, water, and plastic bottles in the process.Lucid, accessible, and deeply researched, Clean explores the ongoing, radical change in the way we think about our skin, introducing readers to the emerging science that will be at the forefront of health and wellness conversations in coming years.
