| 1,500-Year-Old Antarctic Moss Brought Back to Life after being frozen. #cryopreservation The moss comes from Signy Island, a small, glacier-covered island in the Drake Passage offshore of the Antarctic Peninsula. The researchers carbon-dated the different layers, which provided an age estimate for revived moss shoots. The oldest #moss in the core first grew between 1,697 and 1,533 years ago, when the #Mayan empire was at its height and the terror of Attila the Hun was ending in Europe and Central Asia. In the lab, this moss sent out new shoots from its rootlike "#rhizoids," the researchers report. &Rob 2014-03-17 16:54:16 |
