This volume includes contributions by the leading experts in the field of yeast aging. Budding yeast (Saccharomyces cerevisiae) and other fungal organisms provide models for aging research that are relevant to organismic aging and to the aging processes occurring in the human body. Replicative aging, in which only the mother cell ages while the daughter cell resets the clock to zero is a model for the aging of stem cell populations in humans, while chronological aging (measured by survival in stationary phase) is a model for the aging processes in postmitotic cells (for instance, neurons of the brain). Most mechanisms of aging are studied in yeast. Among them, this book discusses: mitochondrial theories of aging, emphasizing oxidative stress and retrograde responses; the role of autophagy and mitophagy; the relationship of apoptosis to aging processes; the role of asymmetric segregation of damage in replicative aging; the role of replication stress; and the role of the cytoskeleton in aging. Modern methods of yeast genetics and genomics are described that can be used to search for aging-specific functions in a genome-wide unbiased fashion. The similarities in the pathology of senescence (studied in yeast) and of cancer cells, including genome instability, are examined.

The word stress is everywhere and highly overused. Everyone is stressed, it seems, all the time. Looking into the meaning of stress in the natural science and the humanities, this book explores cellular stress as cause of and in correlation with what humans experience as stress. When do we psychologically feel stress and when do we show physiological evidence of stress in our brain? Stress is a deviation from what feels normal and healthy. It can be created by social or economic factors and become chronic, which has substantial impacts on the individual and society as a whole. Focusing on poverty as one chronic inducer of stress, this book explores how the lack of pressure-free time, the hardships and unpredictability of everyday life and a general lack of protection lead to destructive toxic stress. This pressure affects cognitive and social functioning, brain development during childhood and may also result in premature aging. How can the sciences inform our understanding of and our response to stress? What can be done about toxic stress both on a personal level and in terms of structures and policies? The book is written for anyone interested in stress, its causes and consequences, and its relationship to poverty.
