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 ...
Physical immortality has also been imagined as a form of eternal torment, as in the myth of Tithonus, or in Mary Shelley's short story The Mortal Immortal, where the protagonist lives to witness everyone he cares about die around him. For additional examples in fiction, see Immortality in fiction.
Wild animals can experience injury from a variety of causes such as predation; intraspecific competition; accidents, which can cause fractures, crushing injuries, eye injuries and wing tears; self-amputation; molting, a common source of injury for arthropods; extreme weather conditions, such as storms, extreme heat or cold weather; and natural disasters.
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 ...
Study of negligibly senescent animals may provide clues that lead to better understanding of the aging process and influence theories of aging. [ 1 ] [ 3 ] The phenomenon of negligible senescence in some animals is a traditional argument for attempting to achieve similar negligible senescence in humans by technological means.
Intrinsic mortality is defined as mortality due to ageing, the physiological decline due to innate processes, whereas extrinsic mortality is the result of environmental factors such as for example predation, starvation, accidents and others. Flying animals such as bats, for example, have fewer predators, and therefore have a low extrinsic ...
Both of these examples cannot be referred to as research. The sample size of each experiment was 2-4 mice at most- which is not a representative amount to draw any conclusions. Secondly, there ...
These two ingredients are cited in ancient Taoist texts as ingredients for immortality. Potassium nitrate is an inorganic salt used today as a natural source of nitrate, and is a useful ingredient ...
