Life on Earth rests on a knife-edge of chemistry that could easily have tipped the other way. As geochemists reconstruct the ...

As we shift toward more sustainable fuels, natural gas and biogas, which mainly contain methane (CH4), have become important sources of energy and raw materials for chemical production. However, these ...

Some of Earth’s earliest microbes evolved the ability to use oxygen hundreds of millions of years before it accumulated in ...

Hydrogen reserves in Earth’s core large enough to supply at least nine oceans may influence processes on the surface today.

A new study suggests the world's oxygen-depleted seas may have a chance of returning to higher oxygen concentrations in the ...
