Cryonic
Cryonics (from ''kryos'', meaning "cold") is the low-temperature freezing (usually at ) and storage of human remains in the hope that resurrection may be possible in the future. Cryonics is regarded with skepticism by the mainstream scientific community. It is generally viewed as a pseudoscience, and its practice has been characterized as quackery. Cryonics procedures can begin only after the "patients" are clinically and legally dead. Procedures may begin within minutes of death, and use cryoprotectants to try to prevent ice formation during cryopreservation. It is not possible to reanimate a corpse that has undergone vitrification, as this damages the brain, including its neural circuits. The first corpse to be frozen was that of James Bedford, in 1967. As of 2014, remains from about 250 bodies had been cryopreserved in the United States, and 1,500 people had made arrangements for cryopreservation of theirs. Even if the resurrection promised by cryonics were possible, ec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cryopreservation
Cryopreservation or cryoconservation is a process where biological material - cells, tissues, or organs - are frozen to preserve the material for an extended period of time. At low temperatures (typically or using liquid nitrogen) any cell metabolism which might cause damage to the biological material in question is effectively stopped. Cryopreservation is an effective way to transport biological samples over long distances, store samples for prolonged periods of time, and create a bank of samples for users. Molecules, referred to as cryoprotective agents (CPAs), are added to reduce the osmotic shock and physical stresses cells undergo in the freezing process. Some cryoprotective agents used in research are inspired by plants and animals in nature that have unique cold tolerance to survive harsh winters, including: trees, wood frogs, and tardigrades. The first human corpse to be frozen with the hope of future resurrection was James Bedford's, a few hours after his c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
KrioRus
KrioRus () is the first cryonics company in Russia. It was founded in 2005 by the ''Russian Transhumanist Movement'' non-governmental organization, NGO. It is the only cryonic company in Europe to possess an own cryonic storage. The company offers the services of freezing the entire bodies or heads of clients in liquid nitrogen with a plan to revive them if such a technology is developed, but takes no legal obligations to do so. History KrioRus was founded in 2005 by a group of nine people who wanted to be cryogenically frozen along with their relatives to be revived in the future. Some of the company founders had past experience in the field of cryopreservation. For instance, in 2003, Igor ARyukhov was the chief advisor to the project that aimed to preserve the brain of a deceased biotechnologist. The company was established as a project run by the ''Russian Transhumanist Movement'' NGO. The same year Lydia Fedorenko became the company's first client, yet by that time KrioRus ...

Resurrection
Resurrection or anastasis is the concept of coming back to life after death. Reincarnation is a similar process hypothesized by other religions involving the same person or deity returning to another body. The disappearance of a body is another similar but distinct belief in some religions. With the advent of written records, the earliest known recurrent theme of resurrection was in Egyptian and Canaanite religions, which had cults of dying-and-rising gods such as Osiris and Baal. Ancient Greek religion generally emphasised immortality, but in the mythos, a number of individuals were made physically immortal as they were resurrected from the dead. The universal resurrection of the dead at the end of the world is a standard eschatological belief in the Abrahamic religions. As a religious concept, resurrection is used in two distinct respects: # a belief in the ''individual resurrections'' of individual souls that is current and ongoing (e.g., Christian idealism, realized e ...

Mind Uploading
Mind uploading is a speculative process of whole brain emulation in which a brain scan is used to completely emulate the mental state of the individual in a digital computer. The computer would then run a simulation of the brain's information processing, such that it would respond in essentially the same way as the original brain and experience having a sentient conscious mind. Substantial mainstream research in related areas is being conducted in neuroscience and computer science, including animal brain mapping and simulation, development of faster supercomputers, virtual reality, brain–computer interfaces, connectomics, and information extraction from dynamically functioning brains. According to supporters, many of the tools and ideas needed to achieve mind uploading already exist or are under active development; however, they will admit that others are, as yet, very speculative, but say they are still in the realm of engineering possibility. Mind uploading may potentiall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brian Wowk
Brian G. Wowk is a Canadian medical physicist and cryobiologist known for the discovery and development of synthetic molecules that mimic the activity of natural antifreeze proteins in cryopreservation applications, sometimes called "ice blockers". As a senior scientist at 21st Century Medicine, Inc., he was a co-developer with Greg Fahy of key technologies enabling cryopreservation of large and complex tissues, including the first successful vitrification and transplantation of a mammalian organ (kidney). Wowk is also known for early theoretical work on future applications of molecular nanotechnology, especially cryonics, nanomedicine, and optics. In the early 1990s he wrote that nanotechnology would revolutionize optics, making possible virtual reality display systems optically indistinguishable from real scenery as in the fictitious Holodeck of ''Star Trek''. These systems were described by Wowk in the chapter "Phased Array Optics" in the 1996 anthology ''Nanotechnology ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James Bedford
James Hiram Bedford (April 20, 1893 – January 12, 1967) was an American psychology professor at the University of California who wrote several books on occupational counseling. He is the first person whose body was cryopreserved after legal death, and remains preserved at the Alcor Life Extension Foundation. Cryonic preservation In June 1965, Ev Cooper's Life Extension Society (LES) offered the opportunity to preserve one person free of charge, stating that "the Life Extension Society now has primitive facilities for emergency short term freezing and storing our friend the large homeotherm (man). 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. Bedford died in 1967 at 73 years old. Bedford left $100,000 to cryonics res ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cryobiology
Cryobiology is the branch of biology that studies the effects of low temperatures on living things within Earth's cryosphere or in science. The word cryobiology is derived from the Greek words κρῧος ryos "cold", βίος ios "life", and λόγος ogos "word". In practice, cryobiology is the study of biological material or systems at temperatures below normal. Materials or systems studied may include proteins, cells, tissues, organs, or whole organisms. Temperatures may range from moderately hypothermic conditions to cryogenic temperatures. Areas of study 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. This usually requir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cryoprotectant
A cryoprotectant is a substance used to protect biological tissue from freezing damage (i.e. that due to ice formation). Arctic and Antarctic insects, fish and amphibians create cryoprotectants ( antifreeze compounds and antifreeze proteins) in their bodies to minimize freezing damage during cold winter periods. Cryoprotectants are also used to preserve living materials in the study of biology and to preserve food products. For years, glycerol has been used in cryobiology as a cryoprotectant for blood cells and bull sperm, allowing storage in liquid nitrogen at temperatures around −196 °C. However, glycerol cannot be used to protect whole organs from damage. Instead, many biotechnology companies are researching the development of other cryoprotectants more suitable for such uses. A successful discovery may eventually make possible the bulk cryogenic storage (or "banking") of transplantable human and xenobiotic organs. A substantial step in that direction has already occu ...

Portland Tribune
The ''Portland Tribune'' is a weekly newspaper published every Wednesday in Portland, Oregon, United States. It is part of the Pamplin Media Group, which publishes a number of community newspapers in the Portland metropolitan area. Launched in 2001, the paper was published twice weekly until 2008, when it was reduced to weekly. It returned to twice-weekly publication in 2014 and was again reduced to weekly publication in 2020. It was distributed free from its 2001 launch until October 2022, then becoming available only by paid subscription or purchase at retail outlets. History 2000–2007 Portland businessman Robert B. Pamplin Jr. announced his intention to found the paper in the summer of 2000. The first issue of the twice-weekly (Tuesdays and Fridays) paper was published February 9, 2001, joining ''The Oregonian'', the city's only daily general-interest newspaper, and the alternative weeklies ''Willamette Week'' and '' The Portland Mercury''. At the time, it was a rare ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crystal
A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. In addition, macroscopic single crystals are usually identifiable by their geometrical shape, consisting of flat faces with specific, characteristic orientations. The scientific study of crystals and crystal formation is known as crystallography. The process of crystal formation via mechanisms of crystal growth is called crystallization or solidification. The word ''crystal'' derives from the Ancient Greek word (), meaning both "ice" and " rock crystal", from (), "icy cold, frost". Examples of large crystals include snowflakes, diamonds, and table salt. Most inorganic solids are not crystals but polycrystals, i.e. many microscopic crystals fused together into a single solid. Polycrystals include most metals, rocks, ceramics, and ice. A third cat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
