By documenting Alaska's lakes and ponds in unprecedented detail, Levenson and colleagues show where and how water bodies can signal underlying permafrost thaw, providing a step toward a ...

In particular, strains of Pseudomonas buried in the permafrost were found to potentially cause potato rot disease. Until now, strains of Pseudomonas had been known as pathogens infecting fruits ...

This slowly builds pressure inside the cryopegs. Eventually, the strain becomes so high that cracks form in the permafrost above the cryopegs. This releases the pressure within the permafrost.
