⭐ Core Definition: Suspended animation

Suspended animation is the slowing or stopping of biological function so that physiological capabilities are preserved. States of suspended animation are common in micro-organisms and some plant tissue, such as seeds. Many animals, including large ones, may undergo hibernation, and most plants have periods of dormancy. This article focuses primarily on the potential of large animals, especially humans, to undergo suspended animation.

In animals, suspended animation may be either hypometabolic or ametabolic in nature. It may be induced by either endogenous, natural or artificial biological, chemical or physical means. In its natural form, it may be spontaneously reversible as in the case of species demonstrating hypometabolic states of hibernation. When applied with therapeutic intent, as in deep hypothermic circulatory arrest (DHCA), usually technologically mediated revival is required.

Suspended animation in the context of Aerobe

An aerobic organism or aerobe is an organism that can survive and grow in an oxygenated environment. The ability to exhibit aerobic respiration may yield benefits to the aerobic organism, as aerobic respiration yields more energy than anaerobic respiration. Energy production of the cell involves the synthesis of ATP by an enzyme called ATP synthase. In aerobic respiration, ATP synthase is coupled with an electron transport chain in which oxygen acts as a terminal electron acceptor. In July 2020, marine biologists reported that aerobic microorganisms (mainly), in "quasi-suspended animation", were found in organically poor sediments, up to 101.5 million years old, 250 feet below the seafloor in the South Pacific Gyre (SPG) ("the deadest spot in the ocean"), and could be the longest-living life forms ever found.

Suspended animation in the context of Spirit (comics character)

The Spirit is a fictional masked crimefighter appearing in American comic books. Created by cartoonist Will Eisner, he first appeared as the main feature of a tabloid-sized comic book insert distributed in the Sunday edition of Register and Tribune Syndicate newspapers. Popularly referred to as "The Spirit Section", the insert ran from June 2, 1940 to October 5, 1952.

The Spirit is the alias of Denny Colt, a private investigator and criminologist based in the fictional Central City, who falls into suspended animation while trying to apprehend the mad scientist Dr. Cobra. Officially pronounced dead, Colt revives after being interred in Wildwood Cemetery. With the blessing of his old friend, police Commissioner Eustace Dolan, Colt becomes a domino mask-wearing "friendly outlaw" who pursues criminals that might otherwise escape capture by traditional law enforcement. The Spirit usually does not possess any superpowers, but relies on his wits and physical prowess, as well as the myth of his supposed resurrection, in his battles against evildoers. He frequently encounters femme fatales over the course of his adventures, including serial seducer P'Gell, thief-turned-troubleshooter Silk Satin, and his estranged childhood friend Sand Saref; he also comes into conflict with his archenemy the Octopus, an unseen criminal mastermind. Other supporting characters include Ellen Dolan, Commissioner Dolan's headstrong daughter and the Spirit's primary love interest, and his recurring sidekick Ebony White, a young, diminutive cab driver.

Suspended animation in the context of Microbial cyst

A microbial cyst is a resting or dormant stage of a microorganism, that can be thought of as a state of suspended animation in which the metabolic processes of the cell are slowed and the cell ceases all activities like feeding and locomotion. Many groups of single-celled, microscopic organisms, or microbes, possess the ability to enter this dormant state.

Encystment, the process of cyst formation, can function as a method for dispersal and as a way for an organism to survive in unfavorable environmental conditions. These two functions can be combined when a microbe needs to be able to survive harsh conditions between habitable environments (such as between hosts) in order to disperse. Cysts can also be sites for nuclear reorganization and cell division, and in parasitic species they are often the infectious stage between hosts. When the encysted microbe reaches an environment favorable to its growth and survival, the cyst wall breaks down by a process known as excystation.
