Scientists Revive 40,000-Year-Old Microbes from Alaska Permafrost
Ancient microbes frozen for up to 40,000 years slowly revive after thawing, potentially increasing greenhouse gas emissions and climate change risks, researchers found.
- 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.

University of Colorado BoulderResearchers wake up microbes trapped in permafrost for thousands of years
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 of […]
Researchers Revive Pleistocene-Age Microbes
Scientists have resurrected ancient microbes from permafrost cores of Late-Pleistocene age (up to 40,000 years old) collected from four locations within the Permafrost Research Tunnel near Fairbanks, Alaska. The post Researchers Revive Pleistocene-Age Microbes appeared first on Sci.News: Breaking Science News.
