24,000-year-old frozen ‘zombie worm’ thawed by…
It thawed out — and then it multiplied.
Scientists efficiently revived a “zombie worm” that had been frozen for 24,000 years, revealing new insight into how life survives in the most unforgiving environments over prolonged durations of time.
According to a research printed in the scientific journal Current Biology, researchers discovered that the microscopic organism — recognized as a rotifer — is a small, multicellular animal generally discovered in freshwater environments that is thought for its uncommon sturdiness, FOX News reported.
The “zombie worm” has been frozen deep within Siberian permafrost since the Late Pleistocene, which was thought of to be the ultimate epoch of the Ice Age, ending roughly 11,700 years in the past.

Scientists consider the Yedoma formation — an ice-rich, organic-laden permafrost fashioned during the Ice Age — helped maintain the specimen in a secure, frozen state for tens of hundreds of years.
Researchers fastidiously thawed out the rotifer under strictly managed laboratory circumstances and had been left shocked when the a number of millennia-old rotifer resumed regular organic capabilities.
And more shockingly, it was ready to reproduce again ainappropriately, indicating that its mobile constructions remained intact after tens of hundreds of years on ice.
“Our report is the hardest proof as of today that multicellular animals could withstand tens of thousands of years in cryptobiosis, the state of almost completely arrested metabolism,” lead researcher Stas Malavin told the Indian Defence Review.
The phenomenon behind the rotifer’s survival is cryptobiosis — a state in which metabolic exercise in organisms slows to nearly nothing, permitting sure life varieties to endure excessive circumstances such as freezing temperatures, dehydration and oxygen deprivation.
While single-celled life varieties or easier constructions have been revived from ice before, the revival of a multicellular organism marks a major breakthrough for scientists, as more advanced life varieties face higher challenges surviving freezing circumstances and thawing without harm.
But the breakthrough comes with a stark warning — as permafrost melts, scientists concern historical microbes may very well be launched into the wild, raising pressing questions about the dangers they might pose.
Despite their microscopic measurement, rotifers have advanced organic options — including digestive systems and simple nervous constructions — making their means to survive long-term freezing particularly outstanding.
Scientists consider the outcomes might have a broader scientific impression, significantly in understanding how cells resist harm brought about by freezing and radiation over time.
The discovery — the second in current years after Russian scientists uncovered Arctic “zombie worms” in 2021 — might also form research in fields like biotechnology and astrobiology, where scientists research how life may endure in excessive, or even extraterrestrial environments.
However, scientists warning that the findings don’t recommend that bigger organisms, such as mammals, may very well be revived after related durations of freezing.

Higher life varieties are far more advanced than microscopic organisms — making them far more prone to drastic mobile harm during the freezing and thawing processes.
Still, the research pushes the identified limits of life on Earth, raising new questions about how long organisms can stay viable under the proper circumstances and probably reshaping how scientists suppose about survival in excessive environments.
