Ultrasound creates light inside the body, opening a new path to targeted treatments
Light has an increasing number of applications in biology and medicine—it can be used to stimulate cell growth, manipulate neural signals, and treat some cancers—but it doesn't easily pass through tissue. Most methods to bring light deep within the body are invasive, requiring either tissue to be re...

Light has an increasing number of applications in biology and medicine—it can be used to stimulate cell growth, manipulate neural signals, and treat some cancers—but it doesn't easily pass through tissue. Most methods to bring light deep within the body are invasive, requiring either tissue to be removed or an optical fiber to be inserted.
