Deep-Sea Pressure Crushes Carbon Cycling

The extreme pressure in the deep sea stifles microbes’ appetite for organic carbon. This finding could have important implications for carbon budgets and geoengineering.

Summer could be earthquake season on Mars

InSight data hint that shifting carbon dioxide ice loads, illumination changes, or solar tides could drive an uptick in marsquakes during northern summer—a “marsquake season.”

Desert life conjures organic carbon from thin air

Without water, photosynthesis shuts down. To survive dry spells, desert microbes scavenge traces of hydrogen from the air and burn it for energy. Some even use hydrogen to fuel carbon fixation.
