TINY WORM COMES BACK TO LIFE AFTER 24,000 YEARS


24,000 YEARS OLD TINY WORM IDENTIFIED 


It's a  microscopic organism has wriggled back to life and reproduced asexually after lying frozen in the vast permafrost  lands of northeastern Siberia for 24,000 years.

Russian scientists found the tiny, ancient animal called the bdelloid rotifer in soil taken from the river Alazeya in Russia's region of Yakutia in the far north.
The bdelloid rotifer, a multicellular organism found in freshwater habitats across the world, is known to be able to withstand extreme cold.
Rotifers live in freshwater marine environments, and are mostly omnivorous. The organisms—which are entirely female—are also one of Mother Nature’s more resilient creatures.

[ TO CLEAR... 
What is multicellular organism ?

Multicellular organisms are organisms that consist of more than one cell, in contrast to unicellular organisms.

Example : Human beings , Plants , Animals , Birds &  Insects.  ]


Previous research suggested it could survive for a decade when frozen at -20 degrees Celsius.

This new case, which was detailed in a study in the journal Current Biology, is by far the creature's longest recorded survival period in a frozen state.

The organism was recovered from samples taken 3.5 metres below ground. The material was dated from between 23,960 and 24,485 years ago, the study said.



Reason to withstand thousands of years !

“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,” Malavin said in a press statement.

[   TO CLARIFY ...
What is Cryptobiosis ?
Cryptobiosis is a state of extreme inactivity in response to adverse environmental conditions. In the cryptobiotic state, all metabolic procedures stop, preventing reproduction, development, and repair.   ]

Land encased in permafrost - where the ground is frozen all year round - has for years thrown up startling scientific discoveries.
Scientists earlier revived microscopic worms called nematodes from sediment in two places in northern Siberia that were dated over 30,000 years old.

SPACE PUPS BORN FROM MOUSE SPERM STORED ON ISS

MOUSE SPERM STORED ON AN INDIAN SPACE STATION IN A FREEZE DRIED FORM The Japanese researchers behind the new work, which they published on June 11 in a news paper, wanted to know how space radiation affects fertility in mammals. As we know the radiation can damage the  DNA  within cells , causing mutations (this is why dermatologists recommend using sunscreen)  & also Environments on Earth with heavy radiation exposure can cause defects in the offspring of animals. Japanese researchers found mouse sperm exposed to high levels of cosmic radiation for nearly six years produced a large brood of healthy, unremarkable "space pups." The sperm was stored in the International Space Station in freeze-dried form. [ To clear , What is cosmic radiation ? Cosmic radiation is an ionizing radiation produced when primary photons and α particles from outside the solar system interact with components of the earth's atmosphere. NSRL is one of the few facilities in the world follows high...

Secrets of tiny diving mammals revealed

Scientists revealed the secrets of tiny creature. Eurasian Water shrew The use of  DNA samples to  construct  an evolutionary tree, scientists  discovered  that diving behaviour   developed   five   distinct   instances   on this   group  of insect- consuming  mammals.. [   To clear.. What is evolutionary tree? (Like above) A  phylogenetic tree  (also phylogeny or  evolutionary tree ) is a branching diagram or a  tree  showing the  evolutionary  relationships among various biological species or other entities based upon similarities and differences in their physical or genetic characteristics. About Water Shrew The Eurasian water shrew, known in the United Kingdom as the water shrew, is a relatively large shrew, up to 10 cm long, with a tail up to three-quarters as long again. It has short, dark fur & a few stiff hairs around the feet and tail.. ] The ability  of ...
