How We Age

Más información sobre el libro

"In this book, Coleen Murphy, a leading scholar of aging, explains that the study of model systems, particularly simple invertebrate animals such as c. elegans, combined with breakthroughs in genomic methods, have allowed scientists to probe the molecular mechanisms of longevity and aging. Understanding the fundamental biological rules that govern aging in model systems provides clues about how we might slow human aging, which could lead in turn to new therapeutics and treatments for age-related disease. Among other vivid examples, Murphy describes research that showed how changing a single gene in the nematode worm C. elegans doubles its lifespan, extending not only the end of life but also the youthful, healthy part of life. Drawing on work in her own lab as well as other recent research, Murphy describes the history and current state of the field, explaining longevity's links to reproduction and mating, sensory and cognitive function, inheritances from our ancestors, and the gut microbiome"--
