Attempts to understand the aging process have generated a great number of theories but few practical therapies. Traditional therapies treat age-related diseases such as cancer and arthritis but do not reverse the aging process itself. A common trend in gerontology is to search for genes that have a demonstrable effect on lifespan, the so-called longevity genes. Many such genes have been identified, and although the manipulation of these genes does not stop the aging process, they provide many valuable insights into the cellular mechanisms of aging. More recently, interest has turned to the use of cloning technology, stem cell analysis, and genetic manipulation in order to produce an effective rejuvenation therapy for cells and the body as a whole.
Aging, Revised Edition describes the field of gerontology and the many theories that scientists have developed over the years to explain the age-related changes that occur in nearly all animals.
Animal Cloning, Revised Edition discusses all aspects of this new biology, including the scientific, ethical, and legal issues. Completely revised and updated, this edition now features full-color photographs and illustrations as well as further resources and Web sites to guide additional research. Beginning chapters discuss cloning within the context of a natural process that many animals use as a survival strategy, followed by the historical development of the nuclear transfer procedure, the cloning of Dolly the sheep, the medical applications of cloning technology, and much more. A new section on plant clones has been added.
