Worms frozen in permafrost for up to 42,000 years come back to life

Nematodes moving and eating again for the first time since the Pleistocene age in major scientific breakthrough, say experts.

The roundworms from two areas of Siberia came back to life in Petri dishes, says a new scientific study. 

‘We have obtained the first data demonstrating the capability of multicellular organisms for longterm cryobiosis in permafrost deposits of the Arctic,’ states a report from Russian scientists from four institutions in collaboration with Princetown University.

Some 300 prehistoric worms were analysed - and two ‘were shown to contain viable nematodes’.

‘After being defrosted, the nematodes showed signs of life,’ said a report today from Yakutia, the area where the worms were found.

‘They started moving and eating.’

One worm came from an ancient squirrel burrow in a permafrost wall of the Duvanny Yar outcrop in the lower reaches of the Kolyma River - close to the site of Pleistocene Park which is seeking to recreate the Arctic habitat of the extinct woolly mammoth, according to the scientific article published in Doklady Biological Sciences this week. 

This is around 32,000 years old. 

Another was found in permafrost near Alazeya River in 2015, and is around 41,700 years old. 

Currently the nematodes are the oldest living animals on the planet.  

They are both believed to be female.

The worms came back to life in a laboratory at The Institute of Physico-Chemical and Biological Problems of Soil Science in Moscow region. 

The scientists say: “Our data demonstrate the ability of multicellular organisms to survive long-term (tens of thousands of years) cryobiosis under the conditions of natural cryoconservation. 

'It is obvious that this ability suggests that the Pleistocene nematodes have some adaptive mechanisms that may be of scientific and practical importance for the related fields of science, such as cryomedicine, cryobiology, and astrobiology.”

The Russian institutions involved in the pioneering research were: The Institute of Physico-Chemical and Biological Problems of Soil Science; Moscow State University; Pertsov White Sea Biological Station, part of Moscow State University; and the Higher School of Economics in Moscow.

The Department of Geosciences, Princeton University, was also involved.

If we can avoid all of the prehistoric microbes, I can't wait to see cryo-tech preservation become reality. May be those terminally ill people who froze themselves really do have something to look forward to.

Fascinating. Now, if we could just keep biblical references out of it...there is much to be learned.

This mean cyrosleep might be possible someday to humans, right? Or should we worry more about possible living things in frozen food that eaten uncooked?

I think it is a fantastic achievement & find! I congratulate the scientists involved! There can only be positive results adding to our knowledge from such a great discovery!!

Great news! Now I can go ahead and freeze myself.
Maybe things will be better 47,000 years from now.

We should probably worry more about threats released by deforestation, moving animals, soil, climate change... Because thats millions of these moving around. Anyway, our world gives more money, time and energy to social networksand empty people than to antivirals, antibiotics and antiparasitic research...

Thats insane. We could use this to travel to another far away Earth-like planet... just like in the movies!

Fantastic find. Unfortunately, the levels of pollution in today's world will probably kill them, if they're exposed to it.

Why are we bringing things back that was Extinct ? Why are we doing what the fallen Angel's did? And what was there lot ? The Great flood. We're screwed.

Just leaving a comment so that people would know that islanders like me read news like this too. We're not all uncivilized!

This is great news. The scientists can now look into our past at the same time the should be very cautious not spreding any unknown virus or prehistoric diseases to the environment. I hope it reveals lot of information about the planet.

Genesis11:6 And the LORD said, Behold, the people is one, and they have all one language; and this they begin to do: and now nothing will be restrained from them, which they have imagined to do.
7 Go to, let us go down, and there confound their language, that they may not understand one another's speech.
8 So the LORD scattered them abroad from thence upon the face of all the earth: and they left off to build the city.
9 Therefore is the name of it called Babel; because the LORD did there confound the language of all the earth: and from thence did the LORD scatter them abroad upon the face of all the earth.
Revelation9:6 And in those days shall men seek death, and shall not find it; and shall desire to die, and death shall flee from them.
