Tiny animal survives after 24,000 years frozen in Siberian permafrost: "A big step forward" By Sophie Lewis Recreating the Ice Age to fight climate change A lot has changed on Earth in just the last few decades, but for a recently revived microscopic creature, it has tens of thousands of years to catch up on.  In a new study published this week in the journal Current Biology, researchers report the surprising survival story of a bdelloid rotifer, a tiny freshwater creature that is common all over the world. The multicellular animals can only be seen under a microscope...

Scientists in a Russian lab have brought back to life miniature “zombies” that were frozen about 3.5 meters (11.5 feet) beneath the Siberian permafrost for 24,000 years (in the Alazeya River). These multicellular microscopic creatures, which are called bdelloid rotifers (or wheel animals), have been living in freshwater locations for approximately 50 million years. Rotifers... Read more »

Animal Revived After Surviving 24,000 Years Frozen In Siberian Permafrost by : Emily Brown on : 08 Jun 2021 09:38 Michael Plewka/PA Images A microscopic animal known as a bdelloid rotifer has been revived after being frozen for 24,000 years in Siberian permafrost.  Russian scientists found the multi-celled organism in a core of frozen soil extracted with a drilling rig from the Alayeza River in the Russian Arctic, after which they allowed it to thaw. Advert The research, published this week in the journal Current Biology, revealed that after spending thousands of years in a state of frozen ...

According to researchers' report published in the online journal Current Biology, these microscopic multicellular lifeforms were obtained from samples gathered by remote drilling rigs in the middle reaches of the Alazeya River in t...
