'Stunning' discovery: Metals can heal themselves

Scientists for the first time have witnessed pieces of metal crack, then fuse back together without any human intervention, overturning fundamental scientific theories in the process. If the newly discovered phenomenon can ...

The great gas hydrate escape

For some time, researchers have explored flammable ice for low-carbon or alternative fuel or as a place to store carbon dioxide. Now, a computer analysis of the ice and gas compound, known as a gas hydrate, reveals key details ...

Catalysts found to convert carbon dioxide to fuel

The goal of tackling global warming by turning carbon dioxide into fuel could be one step closer with researchers using a supercomputer to identify a group of "single-atom" catalysts that could play a key role.

Chemists discover new way to harness energy from ammonia

A research team at the University of Wisconsin-Madison has identified a new way to convert ammonia to nitrogen gas through a process that could be a step toward ammonia replacing carbon-based fuels.
