Book Description
Is the five-second rule legitimate? Are electric hand dryers really bacteria blowers? Am I spraying germs everywhere when I blow on my birthday cake? How gross is backwash? When it comes to food safety and germs, there are as many common questions as there are misconceptions. And yet there has never been a book that clearly examines the science behind these important issues—until now. In Did You Just Eat That? food scientists Paul Dawson and Brian Sheldon take readers into the lab to show, for example, how they determine the amount of bacteria that gets transferred by sharing utensils or how many microbes live on restaurant menus. The authors list their materials and methods (in case you want to replicate the experiments), guide us through their results, and offer in-depth explanations of good hygiene and microbiology. Written with candid humor and richly illustrated, this fascinating book will reveal surprising answers to the most frequently debated—and also the weirdest—questions about food and germs, sure to satisfy anyone who has ever wondered: should I really eat that?

Book Description
Bacteria are invisible, mysterious, deadly, self-sufficient…and absolutely essential for all life, including yours. No other living things combine their elegant simplicity with their incredibly complex role: Bacteria keep us alive, supply our food, and regulate our biosphere. We can’t live a day without them, and no chemical, antibiotic, or irradiation has ever successfully eradicated them. They’re our partners, like it or not--even though some of them will happily kill us. Allies and Enemies tells the story of this amazing, intimate partnership. Authored by Anne Maczulak, a microbiologist who’s hunted and worked with an extraordinary array of bacteria, this book offers a powerful new perspective on Earth’s oldest creatures. You’ll discover how bacteria work, how they evolve, their surprising contributions and uses, the roles they’ve played in human history, and why you can't survive without them. No form of life is more important, and in Maczulak’s hands, none is more fascinating. Outlasted, outnumbered, outsmarted They’ve been here four billion years--and they even outnumber you in your own body How bacteria keep you alive… …and how to keep them from killing you “Humans Defeat Germs!” But not for long… The Invisible Universe The stunning hidden relationships between bacteria and the rest of nature

Book Description
Should educators pay students? Should they make them wear sunglasses, regulate their clothing, allow them to bring animals into classrooms, discourage them from playing videogames, or transform their schools into gymnasiums? These are some of the suggestions that Cockeyed Education examines. This book enables readers to differentiate substantive from cockeyed suggestionsfor improving schools.. It directs them to the suggestions that scholastic experts, politicians, and members of the public have made. Additionally, it introduces them to the case method. It helps them apply this analytical technique to events that range from early Chicago schooling to the 2009 economic stimulus package.

Book Description
The myth of the peace-loving "noble savage" is persistent and pernicious. Indeed, for the last fifty years, most popular and scholarly works have agreed that prehistoric warfare was rare, harmless, unimportant, and, like smallpox, a disease of civilized societies alone. Prehistoric warfare, according to this view, was little more than a ritualized game, where casualties were limited and the effects of aggression relatively mild. Lawrence Keeley's groundbreaking War Before Civilization offers a devastating rebuttal to such comfortable myths and debunks the notion that warfare was introduced to primitive societies through contact with civilization (an idea he denounces as "the pacification of the past"). Building on much fascinating archeological and historical research and offering an astute comparison of warfare in civilized and prehistoric societies, from modern European states to the Plains Indians of North America, War Before Civilization convincingly demonstrates that prehistoric warfare was in fact more deadly, more frequent, and more ruthless than modern war. To support this point, Keeley provides a wide-ranging look at warfare and brutality in the prehistoric world. He reveals, for instance, that prehistorical tactics favoring raids and ambushes, as opposed to formal battles, often yielded a high death-rate; that adult males falling into the hands of their enemies were almost universally killed; and that surprise raids seldom spared even women and children. Keeley cites evidence of ancient massacres in many areas of the world, including the discovery in South Dakota of a prehistoric mass grave containing the remains of over 500 scalped and mutilated men, women, and children (a slaughter that took place a century and a half before the arrival of Columbus). In addition, Keeley surveys the prevalence of looting, destruction, and trophy-taking in all kinds of warfare and again finds little moral distinction between ancient warriors and civilized armies. Finally, and perhaps most controversially, he examines the evidence of cannibalism among some preliterate peoples. Keeley is a seasoned writer and his book is packed with vivid, eye-opening details (for instance, that the homicide rate of prehistoric Illinois villagers may have exceeded that of the modern United States by some 70 times). But he also goes beyond grisly facts to address the larger moral and philosophical issues raised by his work. What are the causes of war? Are human beings inherently violent? How can we ensure peace in our own time? Challenging some of our most dearly held beliefs, Keeley's conclusions are bound to stir controversy.
