A 1998 publication in Experimental Gerontology has become widely cited as providing experimental support for the existence of non-senescing organisms (Martinez, 1998). Fig. 1 in that publication shows thatHydra vulgaris does indeed have low age-specific mortality for an animal of its size. However, as the author notes, declining reproduction is sometimes another sign of senescence and asexual reproduction (budding) was a primary focus of that study. The Abstract reports the following: “The… Expand

TLDR
It is concluded that the applicability of the data obtained in gerontological experiments on hydra to human being is, unfortunately, very limited because normal functioning of many important organs and tissues in highly developed organisms is determined by the presence of postmitotic cells, which actually cannot be replaced. Expand
GERONTOLOGY On the Immortal Hydra . Again
The long history of ideas about the most famous “immortal” (non aging) organism, freshwater hydra, is shortly reviewed. Over the years this polyp has attracted the attention of naturalists interestedExpand
Revamping the Evolutionary Theories of Aging
TLDR
The evolutionary response to extrinsic mortality is likely dependent on multiple interacting factors in the organism, population, and ecology, including food availability, population density, reproductive cost, age-mortality interactions, and the mortality source. Expand
Hydra, a model system for deciphering the mechanisms of aging and resistance to aging
TLDR
The possible mechanisms that help H. vulgaris to sustain stem cell self-renewal and thus bypass aging processes are reviewed, pointing to a key role for proteostasis in the maintenance a large pool of active and plastic epithelial stem cells. Expand

Decline in regeneration during aging: Appropriateness or stochastics?
  • A. Khokhlov

  • Russian Journal of Developmental Biology

There is a standpoint according to which the suppression of the ability of cells in a multicellular organism to proliferate, taking place during aging, as well as the corresponding decline in theExpand
Impairment of regeneration in aging: appropriateness or stochastics?
TLDR
It seems that the quality of the cells themselves does not worsen with age as much as reliability of the organism control over cells, organs and tissues, which leads to an increase in the probability of death. Expand
FoxO and Stress Responses in the Cnidarian Hydra vulgaris
TLDR
These findings imply that basic mechanisms of FoxO regulation arose before the evolution of bilaterians and raise the possibility that FoxO is involved in stress responses of other cnidarian species, including corals. Expand
Evolutionary theories of aging can explain why we age.
TLDR
This chapter describes the evolutionary theories of aging and their consequences for the understanding of the biology of aging as well as the challenges to these theories. Expand
Strategies for Engineered Negligible Senescence
TLDR
The strategies for engineered negligible senescence (SENS) concept is described - a simple and appealing model for the design of therapeutic interventions able to meaningfully and persistently reverse the deleterious effects of aging. Expand

Mortality Patterns Suggest Lack of Senescence in Hydra
TLDR
To test for the presence or absence of aging in hydra, mortality and reproductive rates for three hydra cohorts have been analyzed for a period of four years and the results provide no evidence for aging. Expand
In Brief
TLDR
It is concluded that the two supposedly identical cells produced during cell division are functionally asymmetric; the old pole cell should be considered an aging parent repeatedly producing rejuvenated offspring and therefore immortality may be either too costly or mechanistically impossible in natural organisms. Expand
Senescent sperm performance in old male birds
TLDR
Evidence of declining sperm performance for important reproductive variables not only with age, but also with the sperm of old males performing differentially better in female medium than young males. Expand

With the recent publication of two major symposia on their population and evolutionary biology (Jackson, Buss & Cook, 1985; Harper, Rosen & White, 1986), the tide of interest in the functionalExpand
Replicative ageing in the fission yeast Schizosaccharomyces pombe
TLDR
These experiments provide the first evidence of age asymmetry in cell fission and are consistent with the hypothesis of Jazwinski, that asymmetric division underlies culture immortality. Expand
Cell Movements in Hydra
TLDR
It appears that interstitial cells and nematoblasts move in bulk through the intercellular spaces in some situations, probably due to epithelial cell activities and is used to redistribute cells located in the interstitial spaces. Expand
Senescence in a Bacterium with Asymmetric Division
TLDR
This work presents evidence for senescence, a deterioration of function with age manifested as a drop in survival and reproduction in organisms that should be potentially immortal. Expand
Reproduction by Fragmentation in Corals
TLDR
It is concluded that a number of the most successful corals are adapted to fragment, and have incorporated fragmentation into their life histories. Expand
Effects of male age on the frequencies of germinal and heritable chromosomal abnormalities in humans and rodents.
TLDR
The weight of evidence suggests that the increasing trend toward fathering at older ages may have significant effects on the viability and genetic health of human pregnancies and offspring, primarily as a result of structural chromosomal aberrations in sperm. Expand
Advancing Paternal Age Is Associated with Deficits in Social and Exploratory Behaviors in the Offspring: A Mouse Model
TLDR
This study provides the strongest evidence for deleterious effects of advancing paternal age on social and exploratory behavior and de-novo chromosomal changes and/or inherited epigenetic changes are the most plausible explanatory factors. Expand
