Scientists have revived microscopic worms frozen in Siberian permafrost for roughly 46,000 years, revealing how life can survive extreme cold through cryptobiosis.

Addendum 2

Tardigrades dramatically upregulate DNA repair pathway genes in response to ionizing radiation

* tardigrades survive doses of ionizing radiation 1000x human lethal dose
* specific, robust response to ionizing radiation
* irradiation induces rapid dramatic upregulation of DNA repair genes

Some organisms have ability to suspend life processes when under adverse environmental conditions. Called cryptobiosis or suspended animation, it is a survival tool. Organisms under suspended animation revive when environmental conditions become favourable.

Worms Revived After 46,000 Years Frozen in Siberian Permafrost

* tardigrades, rotifers & nematodes survive harsh conditions by entering dormant state: cryptobiosis
* 2 roundworm (nematode) species buried ~130 ft. in Siberian Permafrost radiocarbon dated 46,000 years
* revived by simply putting them in water

Attention all Mastodon users! I just discovered the most incredible thing and I have to share it with you all.

Have you ever heard of the Tardigrade? It's a tiny, eight-legged creature that can survive in the most extreme environments. They can withstand extreme temperatures, pressures, radiation, and even the vacuum of space.

But that's not all. They can also enter a state of suspended animation called "cryptobiosis" where their metabolic activity slows down to almost nothing. This allows them to survive for decades, even centuries, until conditions are favorable for them to revive.

This is truly amazing and I can't believe we share this planet with such resilient creatures. Let's all take a moment to appreciate the incredible diversity and resilience of life on Earth. #tardigrades #cryptobiosis #nature
