Frozen Waterbears Come Back To Life After 30 Years


Is it possible to revive a frozen body back to life after a long period? Even after as long as thirty years. These days Japanese scientists are trying to find the answers to the query. According to a recent report from Wall Street journal, researchers at Japan’s National Institute of Polar Research have done the resuscitation of a couple of waterbears or moss piglets. These moss piglets were in a frozen state from past 30 years. The moss piglets were collected from some Antarctican moss sample in 1983. Ever since these waterbears were kept frozen and stored at –20 degrees C.

It was in 2014, when they decided to defrost the tiny eight-legged creatures also known as tardigrades. While in the process of defrosting , one water bear died right after 20 days although the other one survived and came back to life after 29 days. Another such experiment has also been reported where the moss piglets were kept frozen for nine long years and were defrosted later.

But this strong survival skills of waterbears are not likely to find in any human, I think. So if Japanese scientists are going to apply the same formula on humans, It might not be a success. But there are a few cases where human body is kept frozen for years to keep it safe and run experiments on it to bring it back to life. As I have written the real life story of Grandpa Bredo Morstoel from Nederland.

Waterbears are so strong internally that they are known as “extremophiles.” Or we can say, these creatures are built this way. Waterbears have the natural ability to shut down their metabolism and keep on surviving for longer period of time.

“This considerable extension of the known length of long-term survival of tardigrades recorded in our study is interpreted as being associated with the minimum oxidative damage likely to have resulted from storage under stable frozen conditions.”
