“It’s fast and dramatic, affecting landscapes in unprecedented ways,” Turetsky said. Permafrost, a perpetually frozen layer under the ground surface, contains rocks, soil, sand and, in some cases, ...

A study has found that as climate change causes the Arctic permafrost to melt, pathogens may awaken and damage crops. The ...

Landslides have uncovered pieces of an ancient glacier near Baffin Island. Researchers believe this is the oldest glacier ice ...

But researchers warned that other pathogens hidden in permafrost could turn out to be harmful to humans. "We are addressing this issue by sequencing the DNA that is present in those layers," said ...
