How often did our ancestors bathe? How often did they wash their clothes and change them? What did they understand cleanliness to be? Why have our hygienic habits changed so dramatically over time? In short, how have we come to be so clean? The Clean Body explores one of the most fundamental and pervasive cultural changes in Western history since the seventeenth century: the personal hygiene revolution. In the age of Louis XIV bathing was rare and hygiene was mainly a matter of wearing clean underclothes. By the late twentieth century frequent - often daily - bathing had become the norm and wearing freshly laundered clothing the general practice. Cleanliness, once simply a requirement for go...
What determines whether complex life will arise on a planet, or even any life at all? Questions such as these are investigated in this groundbreaking book. In doing so, the authors synthesize information from astronomy, biology, and paleontology, and apply it to what we know about the rise of life on Earth and to what could possibly happen elsewhere in the universe. Everyone who has been thrilled by the recent discoveries of extrasolar planets and the indications of life on Mars and the Jovian moon Europa will be fascinated by Rare Earth, and its implications for those who look to the heavens for companionship.
In The Medea Hypothesis, renowned paleontologist Peter Ward proposes a revolutionary and provocative vision of life's relationship with the Earth's biosphere--one that has frightening implications for our future, yet also offers hope. Using the latest discoveries from the geological record, he argues that life might be its own worst enemy. This stands in stark contrast to James Lovelock's Gaia hypothesis--the idea that life sustains habitable conditions on Earth. In answer to Gaia, which draws on the idea of the "good mother" who nurtures life, Ward invokes Medea, the mythical mother who killed her own children. Could life by its very nature threaten its own existence? According to the Medea...
Everyone wonders what tomorrow holds, but what will the real future look like? Not decades or even hundreds of years from now, but thousands or millions of years into the future. Will our species change radically? Or will we become builders of the next dominant intelligence on Earth- the machine? These and other seemingly fantastic scenarios are the very possible realities explored in Peter Ward's Future Evolution, a penetrating look at what might come next in the history of the planet. Looking to the past for clues about the future, Ward describes how the main catalyst for evolutionary change has historically been mass extinction. While many scientist direly predict that humanity will event...
Based on more than a decade's research in South Africa's Karoo Desert, this remarkable journey of discovery and real-life adventure deep into Earth's history is offered by a renowned scientist. Photo insert.
The acute inflammatory response is the body's first system of alarm signals that are directed toward containment and elimination of microbial invaders. Uncontrolled inflammation has emerged as a pathophysiologic basis for many widely occurring diseases in the general population. This book provides an introduction to the cell types, chemical mediators, and general mechanisms of the host's first response to invasion.
Behind each shot there lies an idea or purpose. When setting up a shot, the camera operator can employ a range of visual techniques that will clearly communicate the idea to an audience. Composition is the bedrock of the operator's craft, yet is seldom taught in training courses in the belief that it is an intuitive, personal skill. Peter Ward shows how composition can be learned, to enhance the quality of your work. Based on the author's own practical experience, the book deals with the methods available for resolving practical production questions such as: Does the shot composition accurately reflect the idea that initiated the shot? Will the content and method of presenting the subject ac...
In the tradition of Jon Ronson and Tim Wu, an absorbing and revelatory journey into the American Way of Defying Death . . . As longevity medicine revolutionizes the lives of many older people, the quest to take the next step—to live as long as we choose—has spurred a scientific arms race in search of the elixir of life, funded by Big Tech and Silicon Valley. Once the stuff of Mesopotamian mythology and episodes of Star Trek, the effort to make humans immortal is becoming increasingly credible as the pace of technological progress quickens. It has also empowered a wild-eyed fringe of pseudo-scientists, tech visionaries, scam-artists, and religious fanatics who have given their lives over to the pursuit of immortality. Starting off at the Church of Perpetual Life in Florida and exploring the feuding subcultures around the cryonics industry, Peter Ward immerses himself into an eccentric world of startups, scam artists, scientific institutions, and tech billionaires to deliver this deeply reported, nuanced, and sometimes very funny exploration of the race for immortality — and the potentially devastating consequences should humanity realize its ultimate dream.
In Butterflies: Ecology and Evolution Taking Flight, the world's leading experts synthesize current knowledge of butterflies to show how the study of these fascinating creatures as model systems can lead to deeper understanding of ecological and evolutionary patterns and processes in general. The twenty-six chapters are organized into broad functional areas, covering the uses of butterflies in the study of behavior, ecology, genetics and evolution, systematics, and conservation biology. Especially in the context of the current biodiversity crisis, this book shows how results found with butterflies can help us understand large, rapid changes in the world we share with them—for example, geog...
