How and why We Age
Preeminent cell biologist Leonard Hayflick reveals the results of more than thirty years of pioneering research in the field of aging. Gracefully written, clearly organized, and packed with essential facts and statistics, "How and Why We Age" is a landmark study of the aging process for readers of all ages.
The Hayflick Limit
To be human is to cope with knowing. In the early 1960s, Leonard Hayflick determined that healthy cells can divide only a finite number of times. Known as the Hayflick Limit, it sets an unsurpassable lifespan for our species at just over 120 years. Shifting focus between the limits of the microscope and the limits of the telescope, Matthew Tierney gives voice to a range of characters who scrape out meaning in a carnivalesque universe, one that has birthed black holes and Warner Bros. cartoons, murky market economies, murkier quantum laws, Vincent Price, Molotov cocktails, seedless grapes, Area 51 and competing Theories of Everything.
Cellular Ageing and Replicative Senescence
This book covers the origins and subsequent history of research results in which attempts have been made to clarify issues related to cellular ageing, senescence, and age-related pathologies including cancer. Cellular Ageing and Replicative Senescence revisits more than fifty-five years of research based on the discovery that cultured normal cells are mortal and the interpretation that this phenomenon is associated with the origins of ageing. The mortality of normal cells and the immortality of cancer cells were also reported to have in vivo counterparts. Thus began the field of cytogerontology. Cellular Ageing and Replicative Senescence is organized into five sections: history and origins; ...
The Vaccine Race
"A real jewel of science history...brims with suspense and now-forgotten catastrophe and intrigue...Wadman’s smooth prose calmly spins a surpassingly complicated story into a real tour de force."—The New York Times “Riveting . . . [The Vaccine Race] invites comparison with Rebecca Skloot's 2007 The Immortal Life of Henrietta Lacks.”—Nature The epic and controversial story of a major breakthrough in cell biology that led to the conquest of rubella and other devastating diseases. Until the late 1960s, tens of thousands of American children suffered crippling birth defects if their mothers had been exposed to rubella, popularly known as German measles, while pregnant; there was no vac...
The Mycoplasmatales and the L-phase of Bacteria
A review of the book, The Mycoplasmatales and the L-phase of Bacteria by Leonard Hayflick, Ed. is presented. That organisms which lack cell walls are under intensive study is evident from the table of contents and the size of this book. The editor has drawn together 26 chapters by 35 contributors, mostly from the Second International Conference on the Biology of the Mycoplasmas held in 1966. Fifteen of the chapters are updated and expanded versions of papers published earlier in the 871-page proceedings of the 1966 conference (Biology of the Mycoplasmas, Annals of the New York Academy of Sciences, vol. 143, 1967). The articles are well organized, clearly written, thoroughly referenced, and comprehensive. The book is not abundantly illustrated, but does contain sparkling photographs of mycoplasma organisms as viewed under the electron microscope. The book, covers topics which range from studies of ultrastructure to the epidemiology of Mycoplasma pneumoniae.
Merchants of Immortality
A Discover Best Science Book of the Year: “A fascinating, accurate and accessible account of some of [the] contemporary efforts to combat aging” (The New York Times). Los Angeles Times Book Prize Finalist Named a Best Book of the Year by the New York Times, San Jose Mercury News, and Library Journal An award-winning writer explores science’s boldest frontier—extension of the human life span—interviewing dozens of people involved in the quest to allow us to live longer, better lives. Delving into topics from cancer to stem cells to cloning, Merchants of Immortality looks at humankind’s quest for longevity and tackles profound questions about our hopes for defeating health problems...
Boon and Bane of not Being Subject to the Hayflick Limit
Pre-University Paper from the year 2014 in the subject Biology - Cytology, grade: 15 Punkte = 1,0, , language: English, abstract: All living things have to die. This fundamental truth is held to apply even to the smallest unit of life – cells. However, there is a phenomenon that is sometimes called biological immortality. It refers to cells that live beyond their proclaimed life span, which is roughly set by the Hayflick limit. All cancer cells have acquired this property; they divide indefinitely, which is the essential problem with cancer cells. On the other hand, researchers are very much interested in the molecular mechanism behind this property to may be able to use it to extend life and rejuvenate cells. Cells that are not subject to the Hayflick limit are generally seen as a threat to the human body, however, they are interesting subjects of experiments and scientists have already learned a great deal of knowledge by studying these mutants and continue to gain more important insights into the functioning of any kind of human body cell. Immortal cells can be boon and bane for humankind. Certain aspects of this issue will be discussed.
