Water bear is a small animal less than a millimeter long, living in moss and other familiar places. Its super vitality level makes many people very curious about why it is so tenacious in life. Recently, this mystery has been finally solved, that is, nature's immortal Xiaoqiang!
According to Japanese media reports, recently, researchers such as Professor Arakawa and Professor Qing Zhun of the Institute of advanced life at Keio University in Japan have found part of the explanation that the microorganism "water bearworm", known as the 'strongest organism', will not die even if it dries completely.
According to reports, Arakawa et al. Found several special genetic genes that can cope with extremely dry environment, and also found all kinds of water bearworms that have strong adaptability to dry environment, which often play a role. The work, which is expected to uncover the mystery of strong vitality, was published on July 28 in PLoS Biology, a professional magazine in the United States.

It is reported that this achievement was jointly achieved by Arakawa, guozhiwu and assistant professor of Tokyo University and Professor Mark blackster of Edinburgh University in the UK. Water bear is a small animal less than a millimeter long, living in moss and other familiar places.
It is known that water bearworm can withstand extreme environment such as high temperature, freezing, drying, strong radiation, etc. after drying, it will shrink into a 'dry sleeping state', and can revive when encountering water.

The team analyzed and compared the genomic information of the two species, which have strong adaptability to the dry environment and weak adaptability. In addition to most of the genes that protect cells when they are dry, the team also found genes that lead to a state of dry sleep.
It is understood that in general, cells will die autonomously and orderly under the control of genes due to the effects of oxidation, namely 'apoptosis'. However, the research team found no gene to cause this phenomenon in the water bearworm, which may be the reason why the water bearworm can 'die and come back'.
