An anonymous reader shares an opinion piece from Scientific American: Permafrost covers 24 percent of the Earth’s land surface, and the soil constituents vary with local geology. Arctic lands offer unexplored microbial biodiversity and microbial feedbacks, including the release of carbon to the atmosphere. In some locations, hundreds of millions of years’ worth of carbon is buried. The layers may still…

Clues to Mars life in Earth’s Atacama Desert
Researchers in the U.S. and Spain have discovered a plethora of previously unknown microbes living in wet clay layers below Chile’s arid Atacama Desert. The finding will help future rovers search for life on Mars. Source: https://earthsky.org/space/microbes-clay-atacama-desert-life-on-mars…
Ancient life signs under dinosaur-killing Chicxulub crater
Researchers have found evidence for an ancient microbial ecosystem in a hydrothermal system beneath Mexico’s Chicxulub Crater, thought to be the site of the impact that killed the dinosaurs 66 million years ago.
