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 ...
The loss of a pet or an animal to which one has become emotionally bonded oftentimes results in grief [1] which can be comparable with the death of a human loved one, or even greater, depending on the individual. The death can be felt more intensely when the owner has decided to end the pet's life through euthanasia. [2]
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.
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 ...
A multitude of reasons was presented to support this definition, including uniformity of standards in law for establishing death, consumption of a family's fiscal resources for artificial life support, and legal establishment for equating brain death with death to proceed with organ donation.
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 ...
“Life extension could possibly go wrong in the future if it becomes only accessible to the rich, for example, or makes people become so protective of their extended lives that they become risk ...
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.
