Covering nearly three-quarters of our planet, the world's oceans are a vast and unique ecosystem from which all life on Earth originated. But each year the marine realm is more susceptible to harm by careless exploitation, and as demands for food, waste disposal, transport, and travel increase, the fate of the world's oceans hangs in the balance. This timely guide offers the nonscientist an opportunity to appreciate the importance of this expansive - and fragile - frontier. With selections chosen for their value in identifying the multiple uses of oceans, their resources, and the hurdles they face as the world's population continues to expand and consume their resources at a staggering rate, Oceans collects more than thirty thematically arranged articles from the past decade, including recent pieces written in the wake of the 2004 tsunami. The book features articles that investigate the origins of the world's oceans, the diversity of life in the water, the state of global fisheries, the dangers of natural disasters, and the perils oceans face, whether induced by nature or by humans.With a breadth of topics as wide as the ocean is deep, this Scientific American reader will engage general readers interested in the evolution, ecology, and conservation of the oceanic ecosystem and can be used in courses on introductory oceanography, environmental science, and marine biology.

The international public health scare that resulted last year when a man infected with multidrug-resistant tuberculosis flew overseas from the United States and back illustrates both the fear and the potential impact of highly infectious diseases in a global age. At a time when scientists warn of the potential for an influenza epidemic to rival the deadly outbreak of 1919 and newspapers feature alarming headlines about incidences of mad cow disease, infectious disease will be a critical area of concern and scientific study in the twenty-first century."Infectious Disease" collects thirty of the most exciting, innovative, and significant articles on communicable illness published in the pages of "Scientific American" magazine since 1993. With sections devoted to viral infections, infectious disease, the immune system, and global management and treatment issues, "Infectious Disease" provides general readers and students with an excellent overview of recent research in the field. Roger I. Glass discusses a potential vaccine for the rotavirus - a leading cause of severe childhood diarrhea worldwide and frequent killer of young children in developing nations. Jeffery K.Taubenberger and colleagues investigate the virulent strain of influenza that killed nearly 40 million people in 1919 to suggest treatments and recommend preventative measures. And Paul R. Epstein looks into whether global warming could be harmful to our health, untangling research that suggests that many diseases will flourish as Earth's atmosphere heats up.The prominence of disease in the ecology and evolution of human society has spurred investment in research and technology development, and as a consequence the topic is much discussed in the general and scientific media. "Infectious Disease" is the essential sourcebook for anyone looking for the solid science and compelling narrative behind the stories that make headlines.

From the Scopes “Monkey Trial” of 1925 to the court ruling against the Dover Area School Board’s proposed intelligent design curriculum in 2005, few scientific topics have engendered as much controversy—or grabbed as many headlines—as evolution. And since the debate shows no signs of abating, there is perhaps no better time to step back and ask: What is evolution? Defined as the gradual process by which something changes into a different and usually more complex and efficient form, evolution explains the formation of the universe, the nature of viruses, and the emergence of humans. A first-rate summary of the actual science of evolution, this Scientific American reader is a timely collection that gives readers an opportunity to consider evolution’s impact in various settings. Divided into four sections that consider the evolution of the universe, cells, dinosaurs, and humans, Evolution brings together more than thirty articles written by some of the world’s most respected evolutionary scientists. As tour guides through the genesis of the universe and complex cells, P. James E. Peebles examines the evidence in support of an expanding cosmos, while Christian de Duve discusses the birth of eukaryotes. In an article that anticipated his book Full House, Stephen Jay Gould argues that chance and contingency are as important as natural selection for evolutionary change. And Ian Tatersall makes two fascinating contributions, submitting his view that the schematic of human evolution looks less like a ladder and more like a bush. With the latest on what’s being researched at every level of evolutionary studies, from prospects of life on other planets to the inner working of cells, Evolution offers general readers an opportunity to update their knowledge on this hot topic while giving students an introduction to the problems and methodologies of an entire field of inquiry.

Good news about getting older from Scientific American and Scientific American Mind The Scientific American Healthy Aging Brain taps into the most current research to present a realistic and encouraging view of the well-aged brain, a sobering look at what can go wrong––and at what might help you and your brain stay healthy longer. Neurologists and psychologists have discovered the aging brain is much more elastic and supple than previously thought, and that happiness actually increases with age. While our short-term memory may not be what it was, dementia is not inevitable. Far from disintegrating, the elder brain can continue to develop and adapt in many ways and stay sharp as it ages.  Offers new insights on how an aging brain can repair itself, and the five best strategies for keeping your brain healthyShows how older brains can acquire new skills, perspective, and productivityDispels negative myths about agingExplores what to expect as our brains grow older With hope and truth, this book helps us preserve what we’ve got, minimize what we’ve lost, and optimize the vigor and health of our maturing brains.

Who do we love? Who loves us? And why? Is love really a mystery, or can neuroscience offer some answers to these age-old questions? In her third enthralling book about the brain, Judith Horstman takes us on a lively tour of our most important sex and love organ and the whole smorgasbord of our many kinds of love-from the bonding of parent and child to the passion of erotic love, the affectionate love of companionship, the role of animals in our lives, and the love of God.Drawing on the latest neuroscience, she explores why and how we are born to love-how we're hardwired to crave the companionship of others, and how very badly things can go without love. Among the findings: parental love makes our brain bigger, sex and orgasm make it healthier, social isolation makes it miserable-and although the craving for romantic love can be described as an addiction, friendship may actually be the most important loving relationship of your life.Based on recent studies and articles culled from the prestigious Scientific American and Scientific American Mind magazines, The Scientific American Book of Love, Sex, and the Brain offers a fascinating look at how the brain controls our loving relationships, most intimate moments, and our deep and basic need for connection.
