In the past few years, researchers have opened a new door for ultrasound, developing techniques that harness the familiar, safe and noninvasive sound waves to control genes, alter brain function and deliver drugs to targets with millimeter precision. The advance of what’s being termed sonogenetics offers a new twist on one of biology’s biggest recent successes. ….[READ]
