On an annual trip to the Arctic, a Canadian scientist spotted some moss that had previously been frozen under glaciers for about 400 years. When she took the plant back to the lab, she wondered if it could be brought back to life. Yes, yes it could.
University of Alberta biologist and her colleagues go on annual trips to the Teardrop glacier on Ellesmere Island, located in the Canadian Arctic Archipelago. In the past few years she’s watched the glacier retreat, exposing rock, mud and ancient moss that had been buried under the ice since the Little Ice Age, which lasted from 1550 to 1850, Sheila Pratt reported in the La Farge specializes in studying ancient moss, a type of plant called bryophytes. Usually the moss that was under the ice looks black and dead but La Farge noticed some near the glacier retreat that was still slightly greenish and decided to bring it back to the lab. She told the Edmonton Journal that on closer inspection she noticed a tiny green stem and decided to see whether the plant could be revived.
“I could see some of the stems actually had new growth of green lateral branches, and that said to me that these guys are regenerating in the field, and that blew my mind,” she told .
After being ground up and placed in petri dishes with potting soil for several weeks, some of the moss samples did indeed begin growing. A few months later the dishes were full of the zombie moss. The results of La Farge’s scientific study with her University of Alberta colleagues was just published in the
These are some super special plants. Unlike most land plants we know, bryophytes lack the vascular tissue that helps pump fluids around different parts of the organism, the reported. Instead, they reproduce by cloning their cells — and all you really need to keep it going is one. The fact that these plants could come back after being frozen for hundreds of years has some intense implications. Scientists are for potential medical use and La Farge suggested we send some to Mars and see how the moss fares there.
Given the unprecedented pace of glacier retreats, what other secrets will the ice give up?
