  2. Biological immortality - Wikipedia

    en.wikipedia.org/wiki/Biological_immortality

    Biological immortality (sometimes referred to as bio-indefinite mortality) is a state in which the rate of mortality from senescence (or aging) is stable or decreasing, thus decoupling it from chronological age. Various unicellular and multicellular species, including some vertebrates, achieve this state either throughout their existence or ...

  3. Immortality - Wikipedia

    en.wikipedia.org/wiki/Immortality

    Immortality is the concept of eternal life. [2] Some species possess 'biological immortality' due to an apparent lack of the Hayflick limit. [3] [4] From at least the time of the ancient Mesopotamians, there has been a conviction that gods may be physically immortal, and that this is also a state that the gods at times offer humans.

  4. Negligible senescence - Wikipedia

    en.wikipedia.org/wiki/Negligible_senescence

    Negligible senescence is a term coined by biogerontologist Caleb Finch to denote organisms that do not exhibit evidence of biological aging , such as measurable reductions in their reproductive capability, measurable functional decline, or rising death rates with age. [1]

    In his new book, “Why We Die: The New Science of Aging and the Quest for Immortality,” Nobel Prize-winning molecular biologist Venki Ramakrishnan sifts through past and cutting-edge research ...

  6. Ageing - Wikipedia

    en.wikipedia.org/wiki/Ageing

    Ageing (or aging in American English) is the process of becoming older.The term refers mainly to humans, many other animals, and fungi, whereas for example, bacteria, perennial plants and some simple animals are potentially biologically immortal. [1]

  7. Senescence - Wikipedia

    en.wikipedia.org/wiki/Senescence

    Senescence (/ s ɪ ˈ n ɛ s ə n s /) or biological aging is the gradual deterioration of functional characteristics in living organisms. Whole organism senescence involves an increase in death rates or a decrease in fecundity with increasing age, at least in the later part of an organism's life cycle .

  8. Death - Wikipedia

    en.wikipedia.org/wiki/Death

    Almost all animals who survive external hazards to their biological functioning eventually die from biological aging, known in life sciences as "senescence." Some organisms experience negligible senescence, even exhibiting biological immortality. These include the jellyfish Turritopsis dohrnii, [80] the hydra, and the planarian.

  9. Cellular senescence - Wikipedia

    en.wikipedia.org/wiki/Cellular_senescence

    Theoretically, it is possible upon the discovery of the exact mechanism of biological immortality to genetically engineer cells with the same capability. The length of the telomere strand has senescent effects; telomere shortening activates extensive alterations in alternative RNA splicing that produce senescent toxins such as progerin , which ...
