Scientists Revive 40,000-Year-Old Microbes from Alaska Permafrost
Microbes trapped for 40,000 years in Alaskan permafrost showed slow reactivation and significant growth after six months, raising concerns about greenhouse gas release, researchers said.
- Scientists at the University of Colorado Boulder are reviving ancient microbes trapped in Arctic ice for 40,000 years.
- The microbes were extracted from Alaskan permafrost at the Permafrost Tunnel Research Facility near Fairbanks, which also contains Ice Age mammoth bones.
- After six months, some microbes began producing biofilms, indicating their capability to become active after warm periods.
- Research shows that melting permafrost releases greenhouse gases and potential pathogens, leading to threats to human health.

Scientists wake up microbes trapped in Arctic permafrost for 40,000 years
Far beneath the icy Alaskan tundra, life lay dormant for tens of thousands of years. In ice-laden soil called permafrost, microbes of old slumbered in the dark, entombed with the mammoths and bison. When the Arctic is heating up, that icy tomb is now starting to melt—and the microbes slowly waking up with it. Permafrost is more than frozen ground. It is a natural refrigerator with huge reservoirs of carbon, bigger even than today’s supply in the…
Waking Up Microbes Trapped In Permafrost For Up To 40,000 Years - Astrobiology
In a new study, a team of geologists and biologists led by CU Boulder resurrected ancient microbes that had been trapped in ice—in some cases for around 40,000 years. The study is a showcase for the planet’s permafrost. That’s the name for a frozen mix of soil, ice and rocks that underlies nearly a quarter […] The post Waking Up Microbes Trapped In Permafrost For Up To 40,000 Years appeared first on Astrobiology.
