Scientists have discovered previously unknown viruses dating from 15,000 years ago in ice samples taken from a glacier in the Tibetan plateau
The viruses are unlike any that have been cataloged by scientists before, according to a study published earlier this week in the journal Microbiome.A team including climate scientists and microbiologists from Ohio State University took two ice cores from the summit of the Guliya ice cap, at 22,000 feet above sea level, in western China in 2015.The ice core was 1,017 feet deep, the study's lead author, microbiologist Zhiping Zhong, told CNN on Thursday.
"Ice provides a frozen archive," study co-author Lonnie Thompson, professor of earth sciences at Ohio State and senior research scientist at the university's Byrd Polar Research Center, told CNN on Thursday.Relatively little is known about viruses in glaciers, but the field is growing in importance as ice around the world melts as a result of climate change.
