Technicians preparing a body for cryopreservation in 1985. 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.
The following is a timeline of low-temperature technology and cryogenic technology (refrigeration down to close to absolute zero, i.e. –273.15 °C, −459.67 °F or 0 K). [1] It also lists important milestones in thermometry , thermodynamics , statistical physics and calorimetry , that were crucial in development of low temperature systems.
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 ...
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.
The cryogenic treatment process was invented by Ed Busch (CryoTech) in Detroit, Michigan in 1966, inspired by NASA research, which later merged with 300 Below, Inc. in 2000 to become the world's largest and oldest commercial cryogenic processing company after Peter Paulin of Decatur, IL collaborated with process control engineers to invent the world's first computer-controlled "dry" cryogenic ...
As of October 2023, 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] Alcor also applies its cryonic process to the bodies of pets. As of February 2009, there were 33 animal bodies preserved. [9]
The public began paying attention the following month, when Philip Seymour Hoffman died from an overdose of heroin and other drugs. His death followed that of actor Cory Monteith, who died of an overdose in July 2013 shortly after a 30-day stay at an abstinence-based treatment center.
LES offers to freeze free of charge the first person desirous and in need of cryogenic suspension." Bedford did not take this opportunity, however, but later used his own funds. Bedford suffered from kidney cancer that had later metastasized into his lungs, a condition that was untreatable at the time. [5] Bedford died in 1967 at 73 years old.
