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 ...
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]
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.
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 ...
However, a new study published by scientists at the University of Chicago argues that the increase in human lifespan induced by modern medicine may be reaching its biological limit. In other words ...
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 .
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]
Today, where a definition of the moment of death is required, doctors and coroners usually turn to "brain death" or "biological death" to define a person as being dead; [27] people are considered dead when the electrical activity in their brain ceases. [28] It is presumed that an end of electrical activity indicates the end of consciousness. [29]
