SCIENTISTS HAVE BROUGHT BACK TO LIFE A WORM THAT WAS FROZEN 46,000 YEARS AGO ALL THE WHILE WHEN WOOLLY MAMMOTHS, SABRE-TOOTHED TIGERS, AND MIGHTY ELKS STILL WANDER THE EARTH. THE ROUNDWORM, OF AN EARLY UNSPECIFIED SPECIES, SURVIVED 40 METERS (131.2 FEET) BELOW THE SURFACE IN THE SIBERIAN PERMAFROST IN A INACTIVE STATE KNOWN AS CRYPTOBIOSIS, AS SPECIFIED BY TEYMURAS KURZCHALIA, PROFESSOR EMERITUS AT THE MAX PLANCK INSTITUTE OF MOLECULAR CELL BIOLOGY AND GENETICS IN DRESDEN AND ONE OF THE SCIENTISTS ASSOCIATED WITH THE RESEARCH. ORGANISMS IN A CRYPTOBIOTIC STATE CAN UNDERGO THE COMPLETE ABSENCE OF WATER OR OXYGEN AND RESIST HIGH TEMPERATURES IN ADDITION TO, FREEZING OR INTENSELY SALTY CONDITIONS. THEY STIEXISTING IN A STATES “BETWEEN DEATH AND LIFE,” IN WHICH THEIR METABOLIC RATES DECREASE TO AN INVISIBLE LEVEL, KURZCHALIA EXPLAINED. ONE CAN STOP LIFESTATE AND THEN BEGIN IT FROM THE BEGINNING. THIS A VITAL FINDING,” HE SAID, HE ADDED ALSO THAT OTHER ORGANISMS PREVIOUSLY REVIVED FROM THIS STATE HAD REMAIN ALIVE FOR DECADES RATHER THAN MILLENNIA. FIVE YEARS BACK, SCIENTISTS FROM THE INSTITUTE OF PHYSICOCHEMICAL AND BIOLOGICAL PROBLEMS IN SOIL SCIENCE IN RUSSIA DISCOVERED TWO ROUNDWORM SPECIES IN THE SIBERIAN PERMAFROST. ANASTASIA SHATILOVICH, WHO IS ONE OF THE RESEARCHERS, BROUGHT BACK TO LIVE TWO OF THE WORMS AT THE INSTITUTION BY SIMPLY GIVING THEM WATER,BEFORE SHE TRANSFERED ABOUT 100 WORMS TO THE LABS IN GERMANY FOR MORE ADVANCED ANALYSIS, SHE TRANSPORTED LIFE HER POCKET. AFTER THAWING THE WORMS, THE SCIENTISTS USED RADIOCARBON ANALYSIS OF THE PLANT MATERIAL IN THE SAMPLE TO PROVE THAT THE DEPOSIT HAD NOT BEEN THAWED SINCE BETWEEN 45,839 AND 47,769 YEARS PAST. BUT YET, THEY CAN'T TELL IF THE WORM HAS AN EXISTING SPECIE. LATER ON, GENETIC ANALYSIS PRESIDED OVER BY SCIENTISTS IN DRESDEN AND COLOGNE ESTABLISHED THAT THESE WORMS BELONGED TO A NOVEL SPECIES, WHICH RESEARCHERS GAVE THE NAME PANGROLAIMUS KOLYMAENIS. RESEARCHERS ALSO DISCOVERED THAT THE P. KOLYMAENIS SHARED WITH C. ELEGANS — ANOTHER ORGANISM FREQUENTLY USED IN SCIENTIFIC STUDIES — “A MOLECULAR TOOLKIT” THAT COULD PERMIT IT TO SURVIVE CRYPTOBIOSIS. BOTH ORGANISMS PRODUCE A SUGAR CALLED TREHALOSE, VERY LIKELY ALLOWING THEM TO UNDERGO FREEZING AND DEHYDRATION.
