here will always be people who are fascinated by the idea of freezing a living being and bringing it back to life. The idea of preserving life has been a dream for many generations, and this is especially true in our doomsday era, where rapid climate change and disruptions in the Earth’s magnetic field, combined with private and government satellites and other objects orbiting the Earth, are causing total panic, radical behavior and final solutions on multiple levels.
But apart from the show, the preservation of life has many benefits and would certainly usher in a new stage of human development if it were ever possible. The process of cryopreservation is one way to do this. The animal hero that does it in nature is the wood frog. Wood frogs are able to survive the harshest winters by repeatedly freezing and thawing. This process is called freeze tolerance or cryopreservation.
The wood frog’s ability to survive freezing and thawing is due to a number of adaptations: The water in its cells can expand during freezing, it regulates the concentration of antifreeze proteins, and it has a high tolerance to changes in osmotic pressure. When the wood frog freezes, it turns into an ice cube, leaving its interior intact – this means that it can be frozen again and again without being harmed!
However, there are some things you need to know before attempting this at home. First, the frog must be completely frozen for this process to work. Second, the frog must be kept in liquid nitrogen at a temperature below -321 degrees Fahrenheit (-196 degrees Celsius) long enough for its tissues and cells to freeze completely without damaging it. And if you want your frog back after thawing, there’s no way around it: you need a freezer with an alarm system because if the temperature rises above -62 degrees Celsius (-80 degrees Fahrenheit), your frog will die again.
The wood frog is the first animal on earth to develop a natural way to stop it from freezing to death and if scientists figure out how to repeat the process with human tissue and organs, a second chance would get a life-changing meaning.
The Winter Frog
The wood frog is a small amphibian, about the size of a penny. They are often called “winter frogs” because they have one of the most amazing abilities to survive in cold environments, which allows them to live in areas that would be uninhabitable for other frog species and animals, such as Prospect Creek in Alaska, south of the Brooks Range.
When winter arrives, wood frogs huddle under leaf litter and begin producing a special antifreeze in their blood made up of glucose and glycogen When the cooler winter months arrive, frogs huddle under leaf litter. Soon, they begin producing an antifreeze consisting of glucose and glycogen in their blood.
As the temperature continues to drop, the antifreeze is taken up into their cells. Inside each cell, the sugary syrup keeps the cells plump and strong and prevents ice crystals from forming, which would kill them. When in this state, their hearts stop beating and they stop breathing. As much as 70 percent of the frog’s body is frozen solid. A frog dies when the ice completely covers its body and immobilizes it. However, if they are given a quick move by an animal such as a frog hitching a ride on an insect jumping across a frozen pond, or the beating of wings against its icy cover, their hearts start again and they warm up enough to escape.
A frog’s body is mostly water, so when it freezes, it expands. The pressure is so great that their stomachs burst open and release the enzymes that digest their food. The bulging stomachs are then used as a means of propulsion in order to break the ice and move away from danger. Frogs can also produce and use heat through the same mechanism (i.e., thermal skin).
When a frog hops, its legs are spring-loaded to absorb impacts from the ground. The frog’s legs will not break and its bones will not shatter. In addition, frogs produce a slime that acts as an adhesive and is water-resistant, so when it rains, the frog stays put on its spot.
For now, there is no talk of developing technologies for humans based on every superpower of a frog, and scientists are focused on learning more about how the amazing wood frogs survive by freezing themselves. The biggest groups of interest are transplant medicine and cryonics, the science of freezing humans without killing them for an extended period of time. Both hope to achieve the greatest milestone in their revolutionary history and make life possible forever, at least in theory.
