Cryonics (from Greek: κρύος kryos, meaning "cold") is the low-temperature freezing (usually at −196 °C or −320.8 °F or 77.1 K) and storage of human remains in the hope that resurrection may be possible in the future. [1] [2] Cryonics is regarded with skepticism by the mainstream scientific community. It is generally viewed as a ...
A tank of liquid nitrogen, used to supply a cryogenic freezer (for storing laboratory samples at a temperature of about −150 °C or −238 °F) Controlled-rate and slow freezing, also known as slow programmable freezing (SPF), [18] is a technique where cells are cooled to around -196 °C over the course of several hours.
Cryonics is regarded with skepticism within the scientific community and has been characterized as quackery and pseudoscience. [ 3 ] [ 4 ] As of October 2023 [update] , Alcor had 1,927 members, including 222 who have died and whose corpses have been subject to cryonic processes; [ 5 ] [ 6 ] [ 7 ] 116 bodies had only their head preserved. [ 8 ]
Primitive versions of cryogenic preservation basically just involved injecting a body with chemicals and then freezing it the regular way—something that causes frostbite, which is the ...
At least six major areas of cryobiology can be identified: 1) study of cold-adaptation of microorganisms, plants (cold hardiness), and animals, both invertebrates and vertebrates (including hibernation), 2) cryopreservation of cells, tissues, gametes, and embryos of animal and human origin for (medical) purposes of long-term storage by cooling to temperatures below the freezing point of water.
Nitrogen is a liquid under −195.8 °C (77.3 K).. In physics, cryogenics is the production and behaviour of materials at very low temperatures.. The 13th International Institute of Refrigeration's (IIR) International Congress of Refrigeration (held in Washington DC in 1971) endorsed a universal definition of "cryogenics" and "cryogenic" by accepting a threshold of 120 K (−153 °C) to ...
The Cryonics Institute also specializes in Human Cryostasis, DNA/Tissue Freezing, Pet Cryopreservation, and Memorabilia Storage. [12] [13] The cryonics institute finances itself through membership dues and donations. The cost for cryopreservation is less than $30,000 but the total costs including logistics might add up to more than $100,000.
