A breakthrough achieved at a lab in the United States could bring friction stir welding to assembly lines. The technique involves the use of a spinning tool to generate intense levels of deformation ...

Friction plays a key role in how ruptures unzip faults in the Earth’s crust and release waves that cause destructive shaking. Yet dynamic friction evolution is one of the biggest uncertainties in ...

Dumping literal tons of hot volcanic material down a lab flume may finally have revealed how searing mixtures of hot gas and rock travel so far from volcanic eruptions. These pyroclastic flows can ...
