Researchers are starting to discover the curing powers of plasma—bringing the ion-based form of matter into medical realms. A kind of plasma called non-equilibrium atmospheric pressure plasma can help heal wounds, destroy cancer cells and kill harmful bacteria.

The jets of that doctors might use, however, often become turbulent with the direction and velocity changing dramatically. Now, researchers have found this turbulence likely emerges from heat-induced sound waves generated at the plasma electrodes. This new insight is critical for more consistent and effective medical therapies.

"Now that we understand where the induced turbulence in atmospheric pressure plasma jets is coming from, it may be possible to better control it," said Amanda Lietz of the University of Michigan, who is an author of a new report discussing these results, based on computer simulations, appearing as the cover article this week in the journal Applied Physics Letters.
