Aubrey David Nicholas Jasper de Grey (/ dəˈɡreɪ /; born 20 April 1963) is an English biomedical gerontologist. He is the author of The Mitochondrial Free Radical Theory of Aging (1999) and co-author of Ending Aging (2007). De Grey is known for his view that medical technology may enable human beings alive today not to die from age-related causes. As an amateur mathematician, he has ...
Evolution of ageing. Enquiry into the evolution of ageing, or aging, aims to explain why a detrimental process such as ageing would evolve, and why there is so much variability in the lifespans of organisms. The classical theories of evolution (mutation accumulation, antagonistic pleiotropy, and disposable soma) [1][2][3] suggest that ...
Biogerontology should not be confused with geriatrics, which is a field of medicine that studying the treatment of existing disease in aging people, rather than the treatment of aging itself. There are numerous theories of aging, and no one theory has been entirely accepted.
Biogerontology is the special sub-field of gerontology concerned with the biological aging process, its evolutionary origins, and potential means to intervene in the process. Aim of biogerontology is to prevent age-related disease by intervening in aging processes or even eliminate aging per se.
The activity theory of aging, also known as the implicit theory of aging, normal theory of aging, and lay theory of aging, proposes that aging occurs with more positive outcomes when adults stay active and maintain social interactions as they get older. [1] Activity theory suggests that the aging process is slowed or delayed, and quality of ...
Actor and advocate Brooke Shields says learning how to embrace aging and prioritize preventive health in her 50s feels "like a superpower." Here's why.
Network theory of aging. The network theory of aging supports the idea that multiple connected processes contribute to the biology of aging. Kirkwood and Kowald helped to establish the first model of this kind by connecting theories and predicting specific mechanisms. In departure of investigating a single mechanistic cause or single molecules ...
Timeline of aging research. This timeline lists notable events in the history of research into senescence or biological aging, including the research and development of life extension methods, brain aging delay methods and rejuvenation. People have long been interested in making their lives longer and healthier.
