Cryonic
Cryonics (from el, κρύος ''kryos'' meaning 'cold') is the low-temperature freezing (usually at ) and storage of human remains, with the speculative hope that resurrection may be possible in the future. Cryonics is regarded with skepticism within 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. Cryonics procedures may begin within minutes of death, and use cryoprotectants to prevent ice formation during cryopreservation. It is, however, not possible for a corpse to be reanimated after undergoing vitrification, as this causes damage to the brain including its neural circuits. The first corpse to be frozen was that of James Bedford in 1967. As of 2014, about 250 dead bodies had been cryopreserved in the United States, and 1,500 people had made arrangements for cryopreservation of their corpses. Critics ...

KrioRus
KrioRus (russian: КриоРус) is the first cryonics company in Russia. It was founded in 2005 by the ''Russian Transhumanist Movement'' NGO. It's 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 "resurrected" 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 had ...

Cryopreservation
Cryo-preservation or cryo-conservation is a process where Organism, organisms, organelles, cell (biology), cells, Biological tissue, tissues, extracellular matrix, Organ (anatomy), organs, or any other biological constructs susceptible to damage caused by unregulated chemical kinetics are preserved by cooling to very low temperatures (typically using solid carbon dioxide or using liquid nitrogen). At low enough temperatures, any Enzyme, enzymatic or chemical activity which might cause damage to the biological material in question is effectively stopped. Cryopreservation methods seek to reach low temperatures without causing additional damage caused by the formation of ice crystals during freezing. Traditional cryopreservation has relied on coating the material to be frozen with a class of molecules termed cryoprotectants. New methods are being investigated due to the inherent toxicity of many cryoprotectants. Cryoconservation of animal genetic resources is done with the intentio ...

Resurrection
Resurrection or anastasis is the concept of coming back to life after death. In a number of religions, a dying-and-rising god is a deity which dies and is resurrected. Reincarnation is a similar process hypothesized by other religions, which involves the same person or deity coming back to live in a different body, rather than the same one. The resurrection of the dead is a standard eschatological belief in the Abrahamic religions. As a religious concept, it is used in two distinct respects: a belief in the resurrection of individual souls that is current and ongoing ( Christian idealism, realized eschatology), or else a belief in a singular resurrection of the dead at the end of the world. Some believe the soul is the actual vehicle by which people are resurrected. The death and resurrection of Jesus is a central focus of Christianity. Christian theological debate ensues with regard to what kind of resurrection is factual – either a ''spiritual'' resurrection with ...

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 who 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 rese ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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 currently 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 potentially be accomplished by either of two m ... [...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 requires the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brian Wowk
Brian G. Wowk, Ph.D. is a 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: Mole ... [...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, 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 organ (anatomy), 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 cryogenics, cryogenic storage (or "banking") of organ transplant, transplantable human and xenobiotic organs. A su ...

Electron Microscope
An electron microscope is a microscope that uses a beam of accelerated electrons as a source of illumination. As the wavelength of an electron can be up to 100,000 times shorter than that of visible light photons, electron microscopes have a higher resolving power than light microscopes and can reveal the structure of smaller objects. A scanning transmission electron microscope has achieved better than 50 pm resolution in annular dark-field imaging mode and magnifications of up to about 10,000,000× whereas most light microscopes are limited by diffraction to about 200 nm resolution and useful magnifications below 2000×. Electron microscopes use shaped magnetic fields to form electron optical lens systems that are analogous to the glass lenses of an optical light microscope. Electron microscopes are used to investigate the ultrastructure of a wide range of biological and inorganic specimens including microorganisms, cells, large molecules, biopsy samples, ...
