These areas of knowledge have converged into a modern theory of epidemiology that has been slow to penetrate into textbooks, particularly at the introductory level. Epidemiology: An Introduction closes the gap. It begins with a brief, lucid discussion of causal thinking and causal inference and then takes the reader through the elements of epidemiology, focusing on the measures of disease occurrence and causal effects. With these building blocks in place, the reader learns how to design, analyze and interpret problems that epidemiologists face, including confounding, the role of chance, and the exploration of interactions. All these topics are layered on the foundation of basic principles presented in simple language, with numerous examples and questions for further thought.

    He was a celebrity during the height of America’s Gilded Age. In this book, you will read about his friendship with Mark Twain, his furious competition with his former employer Thomas Edison, his uneasy relationship with billionaire J.P. Morgan, and his rivalry with Albert Einstein. During his lifetime, Tesla revolutionized the field of electrical engineering with his most famous invention: the induction motor. But that wasn’t all he contributed to the world of technology. His coils, turbines, robotic boats, and mysterious “death ray” continue to beguile the imagination and inspire the inventors of the 21st century. But who was Tesla really? This book will take you from his early childhood in Croatia, where he experienced strange optical visions and “luminous phenomenon” that gave him near super-human powers of memory and visualization, to the “War of the Currents”, Thomas Edison’s bizarre campaign to ruin Tesla’s reputation. From trying to fight the Spanish American War with robots, to electrifying the skies of the Colorado desert, and to starting an earthquake in the middle of New York city, learn how Nikola Tesla shaped the world we live in today.

    Focusing on four specific examples — corn, silkworms, domestic cats, and apples — she traces the histories of species that have been fundamentally altered over the centuries by the whims and needs of people.

    Authored by two pediatric nurses, this straightforward guide to feeding, bedtime routines, and medical issues includes an instructional DVD with step-by-step demonstrations of how to care for a newborn to a 6-month-old child.

    Based on six years of research, the book follows a handful of unforgettable characters at Tampa's Lowry Park Zoo: an alpha chimp with a weakness for blondes, a ferocious tiger who revels in Obsession perfume, and a brilliant but tyrannical CEO known as El Diablo Blanco.Zoo Story crackles with issues of global urgency: the shadow of extinction, humanity's role in the destruction or survival of other species. More than anything else, though, it's a dramatic and moving true story of seduction and betrayal, exile and loss, and the limits of freedom on an overcrowded planet-all framed inside one zoo reinventing itself for the twenty-first century. Thomas French, a Pulitzer Prize-winning reporter, chronicles the action with vivid power: Wild elephants soaring above the Atlantic on their way to captivity. Predators circling each other in a lethal mating dance. Primates plotting the overthrow of their king. The sweeping narrative takes the reader from the African savannah to the forests of Panama and deep into the inner workings of a place some describe as a sanctuary and others condemn as a prison. All of it comes to life in the book's four-legged characters. Even animal lovers will be startled by the emotional charge of these creatures' histories, which read as though they were co-written by Dickens and Darwin.Zoo Story shows us how these remarkable individuals live, how some die, and what their experiences reveal about the human desire to both exalt and control nature.

    But a twenty-year affair with steroids led to a life of pissing blood, smuggling drugs, destroying hotel rooms, getting arrested, growing breasts, and lying bloodied in the street after a vicious fight with his best friend.This is Clark's riveting, fiercely candid account of his life, career, and steroid addiction. From an upbringing defined by tragedy and a difficult search for identity to tales of performing center stage at Madison Square Garden and bedding Playboy Bunnies and porn stars, Clark explores the price of fame, the pressure of stardom, and how the whole steroid-fueled fantasy finally imploded.What began in high school as a way to speed up recovery from injury rapidly turned into an all-consuming addiction. With selfdeprecating humor and a trove of incredible stories, Clark provides an eye-opening report on the dangers of steroids both obvious and hidden -- and offers his thoughts on why steroid use remains a persistent problem today. More than just a pulpy expose, "Gladiator" is a triumphant story of self-discovery and redemption.

    They evolved from land-roaming, dog-like creatures into animals that move like fish, breathe like us, can grow to 300,000 pounds, live 200 years and roam entire ocean basins. Whales fill us with terror, awe, and affection--yet we know hardly anything about them, and they only enter our awareness when they die, struck by a ship or stranded in the surf. Why did it take whales over 50 million years to evolve to such big sizes, and how do they eat enough to stay that big? How did their ancestors return from land to the sea? Why do they beach themselves? What do their lives tell us about our oceans, and evolution as a whole? Importantly, in the sweepstakes of human-driven habitat and climate change, will whales survive?Nick Pyenson's research has given us the answers to some of our biggest questions about whales. Nick's rich storytelling takes us to the cool halls deep inside the Smithsonian's priceless fossil collection, to the frigid fishing decks on Antarctic whaling stations, and to the blazing hot desert of Chile where scientists race against time to document the largest fossil whalebone site on earth. Spying on Whales is science writing at its best: an author who is an incredible, passionate writer, at the forefront of his field, on a topic that invokes deep fascination.

    How is it that Homo sapiens formed such a special relationship with what, on the face of it, is a most unlikely ally? It is more than just a story of domestication but an astonishing example of the co-evolution of two species, man and wolf, to each others' mutual benefit. This co-evolution was a vital step in helping Homo sapiens overcome competition from other human species and to expand in numbers from relative obscurity on the margins towards the overwhelming numerical superiority and influence that we enjoy today. The book draws on the rich scientific detail of the genomes, both dog and human, that has accumulated over the past two decades. In each case we see a clear pattern of the origins of both species, resolving questions that have puzzled scientists for centuries. Sykes explores the breadth of this `special relationship' between man and dog. We know that dogs descend from wolves. We know that their domesticated descendants form close bonds with ourselves and there are a multitude of theories to account for our compatible social organisations. But to a geneticist, this is nowhere near powerful enough to explain this most peculiar situation. Many theories explore what it was that propelled Homo sapiens from the position of a scarce, medium-sized primate to the position of complete domination that we enjoy today. The ability to control fire, the evolution of language and the invention of agriculture are three prominent examples. Sykes crucially adds a fourth: our transformation of the wolf into the multi-purpose helpmate that is the dog. We owe our dominance and our survival to the dog.

    Beyond Words, readers travel to Amboseli National Park in the threatened landscape of Kenya and witness struggling elephant families work out how to survive poaching and drought, then to Yellowstone National Park to observe wolves sort out the aftermath of one pack's personal tragedy, and finally plunge into the astonishingly peaceful society of killer whales living in the crystalline waters of the Pacific Northwest.

    (How do we observe the behavior of ants just a few millimeters in size—or monitor activity in a brain as small as the tip of a needle?)Ants’ global dominance (there are 10 quadrillion ants worldwide) and supreme staying power (they have existed since the dinosaurs) give a sense of scale to our own empire- building and destroying. Empire of Ants may leave its human readers asking: Who really runs the world?

    No other creature has inspired in humans an identification so passionate, persistent, or fantastical.The Hive recounts the astonishing tale of all the weird and wonderful things that humans believed about bees and their "society" over the ages. It ranges from the honey delta of ancient Egypt to the Tupelo forests of modern Florida, taking in a cast of characters including Alexander the Great and Napoleon, Sherlock Holmes and Muhammed Ali.The history of humans and honeybees is also a history of ideas, taking us through the evolution of science, religion, and politics, and a social history that explores the bee's impact on food and human ritual. In this beautifully illustrated book, Bee Wilson shows how humans will always view the hive as a miniature universe with order and purpose, and look to it to make sense of their own.

    As singular and strange as some of the weapons we encounter on these pages are, we learn that similar factors set their evolution in motion. Emlen uses these patterns to draw parallels to the way we humans develop and employ our own weapons, and have since battle began. He looks at everything from our armor and camouflage to the evolution of the rifle and the structures human populations have built across different regions and eras to protect their homes and communities. With stunning black and white drawings and gorgeous color illustrations of these concepts at work, Animal Weapons brings us the complete story of how weapons reach their most outsized, dramatic potential, and what the results we witness in the animal world can tell us about our own relationship with weapons of all kinds.
