Mars, one of our closest planetary neighbors, has fascinated people for hundreds of years, partly because it is so similar to ...

Tutolo led a new study of rock samples collected by the Curiosity rover that might have answered this question. The mystery ...

NASA’s Curiosity rover discovered siderite in Gale Crater. This shows Mars had a partial carbon cycle, storing and releasing carbon dioxide.

NASA's Curiosity rover has uncovered evidence of a past carbon cycle on Mars. This breakthrough provides scientists with new ...

Our concept of a 'boundless carbon cycle' would encourage policymakers to better appreciate the couplings between land and water and between the hydrological cycle and the carbon cycle.

A vicious cycle is at play: a steady supply of green water is essential for supporting vegetation that can store planet-heating carbon, but humanity's destructive path, including the destruction ...

The Curiosity rover identified hidden caches of the mineral siderite, which could help explain why Mars lost its habitable climate.

Spray half the samples with water; leave the rest dry ... and nitrogen to the atmosphere and soil for reuse. A balanced carbon cycle is essential. Carbon is a major component in carbohydrates ...

Billions of years ago, Mars was warm, wet, and capable of sustaining liquid water on its surface. Scientists have long believed the Red Planet once had a dense atmosphere rich in carbon dioxide (CO₂), ...

These land-based water bodies bury, cycle and emit significant sums of carbon. A large amount of the carbon taken up by terrestrial systems ends up in inland waters, where it can be buried in ...

The resuspension of seafloor sediments—triggered by human activities such as bottom trawling as well as natural processes ...
