The concept might be based on tardigrades, the "toughest animal on Earth."
http://www.bbc.com/earth/story/20150...imals-on-earth In 1948, the Italian zoologist Tina Franceschi claimed that tardigrades found in dried moss from museum samples over 120 years old could be reanimated. After rehydrating a tardigrade, she observed one of its front legs moving. This finding has never been replicated. But it does not seem impossible. In 1995, dried tardigrades were brought back to life after 8 years. He found that when a tardigrade dries out it retracts its head and its eight legs. It then enters a deep state of suspended animation that closely resembles death. Shedding almost all the water in its body, the tardigrade curls up into a dry husk. Baumann called this a "Tönnchenform", but it is now commonly known as a "tun". Its metabolism slows to 0.01% of the normal rate. It can stay in this state for decades, only reanimating when it comes into contact with water. When tardigrades start to dry out, they seem to make a lot of antioxidants. These are chemicals, like vitamins C and E, that soak up dangerously reactive chemicals. This may mop up harmful chemicals in the tardigrades' cells. The antioxidants may explain one of tardigrades' neatest abilities. If a tardigrade stays in its dry tun state for a long time, its DNA gets damaged. But after it reawakens it is able to quickly fix it. We now know that some tardigrades can tolerate being frozen to -272.8 °C, just above absolute zero. To put that into perspective, the lowest temperature ever recorded on Earth was a balmy -89.2 °C in central Antarctica in 1983. The tardigrades coped with a profound chill that does not occur naturally and must be created in the lab, at which atoms come to a virtual standstill. |
