WASHINGTON (AP) — Microorganisms locked in Antarctic ice for 100,000 years and more came to life and resumed growing when given warmth and nutrients in a laboratory.
Researchers led by Kay Bidle of Rutgers University tested five samples of ice ranging in age from 100,000 years to 8 million years.
“We didn’t really know what to expect. We knew that microorganisms were really hardy,†Bidle, an assistant professor of marine and coastal sciences, said in a telephone interview.
The findings are reported in Monday’s online edition of Proceedings of the National Academy of Sciences.
The researchers tested samples of the oldest known ice on Earth and had success at growing bacteria from the younger samples.
