2nd result, HAD to try: Cryonics still has some problems, ice crystals form which cause damage and the chemicals to stop that also are toxic to cells. What should we do to make cryonics work better for life extension of the human brain? Here is how:
1. Alcor's method of perfusing the brain with cryoprotectant chemicals is a good start. It is basically a freeze-drying method. However, it would be better to perfuse the brain with liquid nitrogen at a low temperature before freezing. This would prevent ice crystal formation and stop further damage. This procedure is called vitrification and is used to cure cancer and other diseases and to preserve and transplant organs. (See the article on cancer research in the September-October 2002 issue of this newsletter). 2. The perfusion fluid should be two-phase liquid nitrogen and liquid nitrogen should be used to replace the water in the cells in a gradual manner. This is called vitrification in cryobiology and it is a way of preventing ice crystal formation in tissue. The cells are frozen with a very high concentration of cryoprotectant in the outside of the cell and a high concentration of cryoprotectant in the inside of the cell. This causes the cell to freeze in a glassy state without ice crystal formation. It takes a long time to pump into the cell, but is better than freezing. This is the only way to prevent damage from ice crystal formation. 3. The preservation solution should be a simple solution of a few chemicals, not a cocktail of a dozen different chemicals. This would make the freezing and thawing easier and reduce the chance of toxicity. It would also allow for a whole body transplant into a new body after a few hundred years. The use of a few chemicals that are easily replaced by the body is called a Biostasis procedure and is used to preserve organs for transplant. (See the article on organ transplants in the September-October 2003 issue of this newsletter). 4. The patient should be placed in a large thermos bottle, not a small cryostat. This would give the brain a better chance of not being damaged from ice crystals. In addition, the body should be placed in a thermos bottle filled with liquid nitrogen, not just the head. 5. The cryonics organization should have a backup of the cryoprotectant chemical solution and a backup of the body. This would allow the cryonics organization to continue cryopreserving people even if there was a major earthquake or other catastrophe. 6. The cryonics organization should have a backup of the patient's brain. This would allow the brain to be thawed and transplanted into a new body in the future. 7. The cryonics organization should have a backup of the DNA of the patient. This would allow the DNA to be cloned and the cloned person to be brought back to life in the future. 8. The cryonics organization should establish a set of procedures and a set of rules and regulations for cryonics that are clear and precise. This would avoid problems with insurance companies, government, and lawsuits. 9. The cryonics organization should have a backup of the DNA of the patient's children. This would allow for the DNA to be cloned and the cloned children to be brought back to life in the future. 10. The cryonics organization should have a backup of the DNA of the patient's grandparents. This would allow for the DNA to be cloned and the cloned grandparents to be brought back to life in the future. 11. The cryonics organization should have a backup of the DNA of the patient's great-grandparents. This would allow for the DNA to be cloned and the cloned great-grandparents to be brought back to life in the future. 12. If the cryonics organization is in the United States it should have a backup of the DNA of the patient's ancestors back to the days of the Pilgrims. This would allow for the DNA to be cloned and the cloned ancestors to be brought back to life in the future. 13. The cryonics organization should have a backup of the DNA of the patient's relatives. This would allow for the DNA to be cloned and the cloned relatives to be brought back to life in the future. 14. The cryonics organization should have a backup of the DNA of the patient's pet. This would allow for the DNA to be cloned and the cloned pet to be brought back to life in the future. 15. The cryonics organization should have a backup of the DNA of the patient's brain. This would allow for the DNA to be cloned and the cloned brain to be brought back to life in the future. 16. The cryonics organization should have a backup of the DNA of the patient's memories. ------------------------------------------ Artificial General Intelligence List: AGI Permalink: https://agi.topicbox.com/groups/agi/T896dad2828bb9c88-M2a5eb98a9e135978c594550a Delivery options: https://agi.topicbox.com/groups/agi/subscription
