Beneath our feet, an invisible world of electron exchanges quietly drives the chemistry that sustains ecosystems, controls water quality, and even determines the fate of pollutants.

Electrons flow underground in ways far more extensive than once believed, forming networks that link distant chemical zones. Minerals, organic molecules, and specialized bacteria can act as bridges, ...

A biosignature is any characteristic, element, molecule, substance or feature that serves as evidence for past or present life. It must be something that cannot be produced without life. Some examples ...

The idea of ancient life on Mars is a fascinating one, and the Perseverance rover might have found signs of it. But there are some caveats to that discovery.

"This research dramatically reduces the timeline for discovering hydrogen production materials, bringing commercialization significantly closer," professor Hyungyu Jin of the Pohang University of ...
