Senescence (or aging) is a deterioration of function with age manifested as a drop in survival and reproduction ( [1][1] ). A fundamental question about senescence has not been settled: Which organisms should be senescent, and which should be potentially immortal? We present evidence for senescence 
Senescence: Even Bacteria Get Old
Conditional and replicative senescence in Escherichia coli.
Senescence can explain microbial persistence.
TLDR
Using a mathematical model including age structure, it is shown that senescence provides a natural explanation for persistence-related phenomena, including the observations that the persister fraction depends on growth phase in batch culture and dilution rate in continuous culture.
Role of asymmetric cell division in lifespan control in Saccharomyces cerevisiae.
TLDR
The key quality control mechanisms in budding yeast that contribute to asymmetric cell division of aging determinants including mitochondria, endoplasmic reticulum (ER), vacuoles, extrachromosomal rDNA circles (ERCs), and protein aggregates are described.
Evolutionary ideas on the nature of aging
TLDR
Facts are considered showing that novel forms of aging and mechanisms counteracting them, antiaging systems, have appeared simultaneously with development of the evolutionary form.
Damage Repair Versus Aging in Biofilms
TLDR
It is suggested that damage segregation is only beneficial when active and effective, extrinsic mortality is high and a degree of multicellularity is present, and not when clearly asymmetric cell division is feasible, both in biofilms and chemostats.
Genetic Manipulation of Glycogen Allocation Affects Replicative Lifespan in E. coli
TLDR
It is demonstrated how manipulations of nutrient allocation can lead to the exclusion of the chromosome and limit replicative lifespan in E. coli, and illustrated how mutations can have phenotypic effects that are specific for cells with old poles.
Bacterial aging: from mechanistic basis to evolutionary perspective
TLDR
In this paper, the current view on the mechanistic background and evolutionary significance of bacterial kind of aging is presented, with particular emphasis on the role of asymmetric cell division, the characteristics of stationary growth phase, and therole of oxidative protein damage.

Optimally, mutation and the evolution of ageing
TLDR
Evidence for the importance of both selection against late-acting mutations and selection against deleterious mutations is emerging, and unravelling their relative importance presents experimentalists with a major challenge.
Asymmetric Inheritance of Oxidatively Damaged Proteins During Cytokinesis
TLDR
Findings suggest that a genetically determined, Sir2p-dependent asymmetric inheritance of oxidatively damaged proteins may contribute to free-radical defense and the fitness of newborn cells.
Generating and Exploiting Polarity in Bacteria
TLDR
Some of the schemes bacteria use to orchestrate dynamic changes at their poles and how these polar events execute cellular functions are explored.

Life Span of Individual Yeast Cells
TLDR
This report describes an experiment designed to determine the life- span of single yeast cells and includes consideration of possible mechanisms for life-span limitation.
