Scientists discover a bacterium that "breathes" uranium and renders it immobile
A strain of bacteria that "breathes" uranium may hold the key to cleaning up polluted groundwater at sites where uranium ore was processed to make nuclear weapons.

(PhysOrg.com) -- Recently, an international group of researchers discovered that the underlying mechanism producing high-temperature superconductivity in a widely studied class of copper-oxygen-based superconductors may be ...
The Earth's oceanic crust covers an enormous expanse, and is mostly buried beneath a thick layer of mud that cuts it off from the surface world. Scientists now document life deep within the oceanic crust that appears to be ...
