A Japanese research institute has risen successfully bear water, microanimal able to survive in extreme environmental conditions, it was found frozen at the South Pole over 30 years.
The National Institute of Polar Research of Japan (NIPR) said in a statement that the issue of Tardigrade (popularly known as water bear) raised was found in some samples of moss obtained in November 1983 near the polar base Showa Japan has in East Antarctica.
The process of thawing water bear began in May 2014, according to the NIPR.
The agency said that so far He had managed to revive one of these microanimales (those that can only be seen under a microscope) after a nine-year freeze, so this achievement would be a new record.
The Tardigrade is considered the living being stronger, being able to survive in extreme conditions of temperature (more than 100 degrees Celsius and below 200 Celsius), pressure or radiation.
In fact, it is the only animal that has managed to survive in outer space, as demonstrated by an experiment conducted in 2007.
The water bears are able to enter a state of cryptobiosis, a process that allows them to survive in extreme environments.
By cryptobiosis tardigrades stop or reduce all metabolic processes until the environmental conditions return to normal.
Researchers NIPR so consider the survival of the specimen after being held in temperatures below 20 degrees Celsius for more than three decades it will help to better understand the processes criptobiónicos.
