Methuselah Flies


Book Description

Methuselah Flies presents a trailblazing project on the biology of aging. It describes research on the first organisms to have their lifespan increased, and their aging slowed, by hereditary manipulation. These organisms are fruit flies from the species Drosophila melanogaster, the great workhorse of genetics. Michael Rose and his colleagues have been able to double the lifespan of these insects, and improved their health in numerous respects as well. The study of these flies with postponed aging is one of the best means we have of understanding, and ultimately achieving, the postponement of aging in humans. As such, the carefully presented detail of this book will be of value to research devoted to the understanding and control of aging.Methuselah Flies: ? is a tightly edited distillation of twenty years of work by many scientists? contains the original publications regarding the longer-lived fruit flies? offers commentaries on each of the topics covered ? new, short essays that put the individual research papers in a wider context? gives full access to the original data ? captures the scientific significance of postponed aging for a wide academic audienc

Ending Aging


Book Description

MUST WE AGE? A long life in a healthy, vigorous, youthful body has always been one of humanity's greatest dreams. Recent progress in genetic manipulations and calorie-restricted diets in laboratory animals hold forth the promise that someday science will enable us to exert total control over our own biological aging. Nearly all scientists who study the biology of aging agree that we will someday be able to substantially slow down the aging process, extending our productive, youthful lives. Dr. Aubrey de Grey is perhaps the most bullish of all such researchers. As has been reported in media outlets ranging from 60 Minutes to The New York Times, Dr. de Grey believes that the key biomedical technology required to eliminate aging-derived debilitation and death entirely—technology that would not only slow but periodically reverse age-related physiological decay, leaving us biologically young into an indefinite future—is now within reach. In Ending Aging, Dr. de Grey and his research assistant Michael Rae describe the details of this biotechnology. They explain that the aging of the human body, just like the aging of man-made machines, results from an accumulation of various types of damage. As with man-made machines, this damage can periodically be repaired, leading to indefinite extension of the machine's fully functional lifetime, just as is routinely done with classic cars. We already know what types of damage accumulate in the human body, and we are moving rapidly toward the comprehensive development of technologies to remove that damage. By demystifying aging and its postponement for the nonspecialist reader, de Grey and Rae systematically dismantle the fatalist presumption that aging will forever defeat the efforts of medical science.




Experimental Evolution


Book Description

This volume summarizes studies in experimental evolution, outlining current techniques and applications, and presenting the field's range of research.




The Evolution of Aging


Book Description

Goldsmith provides a historical review of biological aging theories including underlying evolution and genetics issues and describes exciting recent discoveries and new theories that are causing renewed interest in aging-by-design.




The Future of Aging


Book Description

Just as the health costs of aging threaten to bankrupt developed countries, this book makes the scientific case that a biological "bailout" could be on the way, and that human aging can be different in the future than it is today. Here 40 authors argue how our improving understanding of the biology of aging and selected technologies should enable the successful use of many different and complementary methods for ameliorating aging, and why such interventions are appropriate based on our current historical, anthropological, philosophical, ethical, evolutionary, and biological context. Challenging concepts are presented together with in-depth reviews and paradigm-breaking proposals that collectively illustrate the potential for changing aging as never before. The proposals extend from today to a future many decades from now in which the control of aging may become effectively complete. Examples include sirtuin-modulating pills, new concepts for attacking cardiovascular disease and cancer, mitochondrial rejuvenation, stem cell therapies and regeneration, tissue reconstruction, telomere maintenance, prevention of immunosenescence, extracellular rejuvenation, artificial DNA repair, and full deployment of nanotechnology. The Future of Aging will make you think about aging differently and is a challenge to all of us to open our eyes to the future therapeutic potential of biogerontology.




Does Aging Stop?


Book Description

Does Aging Stop? reveals the most paradoxical finding of recent aging research: the cessation of demographic aging. The authors show that aging stops at the level of the individual organism, and explain why evolution allows this. The implications of this counter-intuitive conclusion are profound, and aging research now needs to accept three uncomfortable truths. First, aging is not a cumulative physiological process. Second, the fundamental theory that is required to explain, manipulate, and probe the phenomena of aging comes from evolutionary biology. Third, strong-inference experimental strategies for aging must be founded in evolutionary research, not cell or molecular biology. The result of fifteen years of research bringing together new applications of evolutionary theory, new models for demography, and massive experimentation, Does Aging Stop? advances an entirely new foundation for the scientific study of aging.




Conceptual Breakthroughs in The Evolutionary Biology of Aging


Book Description

Conceptual Breakthroughs in the Evolutionary Biology of Aging continues the innovative Conceptual Breakthroughs series by providing a comprehensive outline of the major breakthroughs that built the evolutionary biology of aging as a leading scientific field. Following the evolutionary study of aging from its humble origins to the present, the book's chapters treat the field's breakthroughs one at a time. Users will find a concise and accessible analysis of the science of aging viewed through an evolutionary lens. Building upon widely-cited studies conducted by author Michael Rose, this book covers 30 subsequent years of growth and development within the field.The book highlights key publications for those who are not experts in the field, providing an important resource for researchers. Given the prevailing interest in changing the aging process dramatically, it is a powerful tool for readers who have a vested interest in understanding its causes and future control measures. - Reviews cell-molecular theories of aging in the light of evolutionary biology - Offers an evolutionary analysis of prospects for mitigating aging not commonly discussed within private and public sectors - Provides readers with a radically different perspective on contemporary biological gerontology, specifically through the lens of evolutionary biology




The Long Tomorrow


Book Description

The conquest of aging is now within our grasp. It hasn't arrived yet, writes Michael R. Rose, but a scientific juggernaut has started rolling and is picking up speed. A long tomorrow is coming. In The Long Tomorrow, Rose offers us a delightfully written account of the modern science of aging, spiced with intriguing stories of his own career and leavened with the author's engaging sense of humor and rare ability to make contemporary research understandable to nonscientists. The book ranges from Rose's first experiments while a graduate student--counting a million fruit fly eggs, which took 3,000 hours over the course of a year--to some of his key scientific discoveries. We see how some of his earliest experiments helped demonstrate that "the force of natural selection" was key to understanding the aging process--a major breakthrough. Rose describes how he created the well-known Methuselah Flies, fruit flies that live far longer than average. Equally important, Rose surveys the entire field, offering colorful portraits of many leading scientists and shedding light on research findings from around the world. We learn that rodents given fifteen to forty percent fewer calories live about that much longer, and that volunteers in Biosphere II, who lived on reduced caloric intake for two years, all had improved vital signs. Perhaps most interesting, we discover that aging hits a plateau and stops. Popular accounts of Rose's work have appeared in The New Yorker, Time magazine, and Scientific American, but The Long Tomorrow is the first full account of this exciting new science written for the general reader. "Among his peers, Rose is considered a brilliantly innovative scientist, who has almost single-handedly brought the evolutionary theory of aging from an abstract notion to one of the most exciting topics in science."--Malcolm Gladwell, The New Yorker




Longevity and Frailty


Book Description

Understanding the relationship between frailty and longevity becomes increasingly important as the world continues to age and life expectancy in most countries continues to increase. The articles contained in this book are the outcome of a colloquium sponsored by Fondation IPSEN in which interdisciplinary perspectives were brought to bear on conceptual, empirical and clinical aspects of this relationship. The result is a unique, innovative and timely blend of papers on topics ranging from frailty concepts in animal models and early Homo sapiens, to documentation of progress in morbidity compression, on the relationships between frailty and impairments and inflammation, and perspectives on long-term health care needs in an aging world.
