Therapeutic focused ultrasound and tissue fields
Sound waves can be focused deep inside the body to heat tissue, open the barrier protecting the brain, or change nerve activity, without any cut. How the sound actually acts on cells and how to aim it through bone are open questions.
Why it matters
These are the only non-ionizing ways to deliver a controlled physical effect to a deep target, and both safety and dose control depend on the unresolved physics.
