Japan has just revived a frozen creature after 30 years

Water bears were only revived after 9 years but none of them lasted 30 years.

The Japan Polar Research Institute has just announced that its scientists succeeded in reviving a Tardigrade that was frozen for more than 30 years, after being collected in Antarctica.

Japanese scientists have successfully resurrected ice-packed water bears for more than 30 years, after finding it in Antarctica.

Tardigrade , also known as water bear, is an "extremophile" organism that has microscopic dimensions living in water, can exist in extremely harsh environments from temperatures close to absolute zero to the boiling temperature of water, six times the pressure at the deepest point of the seabed and radiation hundreds of times more deadly. They will enter a state called cryptobiosis under certain conditions, when the circulatory system will slow down or stop completely for a very long time.

The European Space Agency once sent 3000 water bears to space in 12 days in 2007, making them the first animals to survive in the cosmic environment.

The water bear used in these studies, whose body length was less than 1 millimeter, was found in moss plants near Showa Station in Antarctica in November 1983. They were frozen at minus 20 degrees Celsius and brought About hosting in Japan. The researcher reported that they were defrosted in May 2014.

Equipment to check the survival of foreign bears.

The specimens were originally collected to study moss, but the researchers found two water bears and an egg, the institute spokesman said. They succeeded in restoring eggs and one of these eight-legged organisms, it began to move and consume food after about two weeks. After that, he gave birth to 19 eggs, 14 of them hatched.

While the first batch of eggs consumes more time to hatch than the latter, there are no mutations found in newborn babies. This study was published in Cryobiology last month.

Previously, water bears were only revived after 9 years, but none of them lasted for 30 years, according to what the institute reports."These more detailed studies will improve understanding of the mechanism and conditions of such long-term survival of cryptobiosis life forms , " the scientists said in the study.
