Scientists revived tiny Siberian worms that had been frozen in permafrost for 42,000 years — and they started moving and eating

Agricultural Research Service/ Wikimedia Commons Russian scientists have revived tiny worms that had been frozen for 42,000 years. After being removed from Siberian permafrost, the worms were gradually thawed in a lab until they started moving around and consuming food. The scientists say their findings could have implications for astrobiology and cryomedicine.  A group of […]

Submerged permafrost releasing methane, but not into the atmosphere

(credit: John Kessler Lab) The Earth responds to climate change in interesting ways, sometimes producing what we call “feedbacks,” which can either amplify global warming or dampen it. Some of the feedbacks that can amplify warming have behavior that is hard to predict in the […]

What lies beneath: Melting Siberian permafrost has revealed some terrifying creatures (PHOTOS)

The Siberian unicorn – long believed to have died out 350,000 years ago – was actually still alive as recently as 29,000 years ago, according to the analysis of a well-preserved skull found in the Pavlodar region of Kazakhstan. Unicorn enthusiasts will be disappointed to learn that the extinct creature – also known as Elasmotherium […]

Alaska’s thawing permafrost could be gone in decades – study

The permafrost that covers great swaths of Siberia, northern Canada, Alaska and Greenland is warming twice as fast as other parts of the planet and could be gone by midcentury, causing more warming and releasing gigatonnes of carbon dioxide and methane. “[That] has all kind of consequences both locally for this region, for the animals […]

The Arctic seed vault had to deal with melting permafrost last winter

Completed in 2008, the Global Seed Vault is a remote archive for safeguarding seeds for thousands of cop varieties. If anything dramatic should happen elsewhere around the world, we want these seeds to be there. […]
