They influence virtually all of the growing individual's characteristics, from determining its sex to controlling the numbers of toes and fingers to shaping intricate details of brain structure.Scientific research over the last 50 years has revealed that this hormonal control of development is vulnerable to disruption by synthetic chemicals. Through a variety of mechanisms, hormone-disrupting chemicals (also known as endocrine disrupting chemicals or endocrine disruptors) interfere with the natural messages and alter the course of development, with potential effects on virtually all aspects of bodily function.Our Stolen Future explores the scientific discovery of endocrine disruption. The investigation begins with wildlife, as it was in animals that the first hints of widespread endocrine disruption appeared. The book then examines a series of experiments examining endocrine disruption of animals in the laboratory which show conclusively that fetal exposure to endocrine disrupting chemicals can wreak life-long damage. These experiments also reveal some of the biological processes by which these chemicals have their effects, and that endocrine disruption effects can be caused by exposure to infinitesimally small amounts of contaminant. Moving from animals to people, Our Stolen Future summarizes a series of well-studied examples where people have been affected by endocrine disrupting chemicals, most notably the synthetic hormone dietheylstilbestrol (DES), to which several million women were exposed through misguided medical attempts to manage difficult pregnancies in the 1950s, '60s and '70s.Our Stolen Future then asks a broader, more difficult and more controversial set of questions. Given what is known from wildlife and laboratory studies, and from examples of well-studied human exposure, and given that exposure to endocrine disrupting chemicals in the real world is widespread at levels comparable to those sufficient to cause animal harm, what effects should health scientists be looking for in people in general? Effects to be expected include declines in fertility and other impacts on the reproductive system of both men and women, impairments in disease resistance, and erosions in intelligence.

    But how does virality actually work? In The Rules of Contagion, epidemiologist Adam Kucharski explores topics including gun violence, online manipulation, and, of course, outbreaks of disease to show how much we get wrong about contagion, and how astonishing the real science is.Why did the president retweet a Mussolini quote as his own? Why do financial bubbles take off so quickly? And why are disinformation campaigns so effective? By uncovering the crucial factors driving outbreaks, we can see how things really spread -- and what we can do about it.Whether you are an author seeking an audience, a defender of truth, or simply someone interested in human social behavior, The Rules of Contagion is an essential guide to modern life.

    Arriving at Santiago Atitlan, a Tzutujil Mayan village on the breathtaking shores of Lake Atitlan, Prechtel met Nicolas Chiviliu Tacaxoy--perhaps the most famous shaman in Tzutujil history--who believed Prechtel was the new student he had asked the gods to provide. For the next thirteen years, Prechtel studied the ancient Tzutujil culture and became a village chief and a famous shaman in his own right.In Secrets of the Talking Jaguar, Prechtel brings to vivid life the sights, sounds, scents, and colors of Santiago Atitlan: its magical personalities, its beauty, its material poverty and spiritual richness, its eight-hundred-year-old rituals juxtaposed with quintessential small-town gossip. The story of his education is a tale filled with enchantment, danger, passion, and hope.
