Landscape to atomic scales: Researchers apply new approach to pyrite oxidation
Pyrite, or fool's gold, is a common mineral that reacts quickly with oxygen when exposed to water or air, such as during mining operations, and can lead to acid mine drainage. Little is known, however, about the oxidation ...

Rock-breathing bacteria are electron spin doctors, study shows
Electrons spin. It's a fundamental part of their existence. Some spin "up" while others spin "down." Scientists have known this for about a century, thanks to quantum physics.

Surfaces that grip like gecko feet could be easily mass-produced
Why did the gecko climb the skyscraper? Because it could; its toes stick to about anything. For a few years, engineers have known the secrets of gecko stickiness and emulated it in strips of rubbery materials useful for picking ...
