Worms from Siberian ice after 40,000 years back to life

Worms that 40,000 years ago in a Siberian ice path, turn again to life, as have Russian biologists discovered.

The biologists will have more than 300 samples from various layers of frozen soil have been excavated. The ground in the steel comes from a variety of eras. In two of those samples were the biologists viable roundworms discover. Through carbon dating scientists determine that the worms at least 40,000 years old. But what is even more noticeable: in a hot lab, of about 20 degrees, they could come to life. After some time they started again around, to crawl and to eat.

That worms after 40,000 years in ice can survive, means that it is possible also that other organisms, such as viruses and bacteria, so long in the permafrost will remain. That due to climate change, the permafrost continue to melt, so it can also mean that potentially deadly viruses and bacteria after such a long ‘winter sleep’ can return.

Methane gas

At the same time facing the Siberian region with another problem that the risk of the ‘thaw’ of the ‘ancient’ bacteria still increases: there are giant bubbles of methane gas under the ground. Because of the warm weather in Siberia as a result of climate change thaws the soil much more than normal, so there are huge amounts of methane gas can be released. And that gas leads to a much larger greenhouse effect for the earth than the emissions of CO2 in the air.

The result: a vicious circle, because by a greater greenhouse effect, will make the permafrost more quickly thaw and will methaangasbellen so even faster and in greater quantities released, what the global warming would dramatically increase.
