The future in ultrasound imaging will let doctors view specific cells and molecules deeper in the body, such as those associated with brain tumors or bacteria in our gut. Researchers at Caltech engineered protein-shelled nanostructures called gas vesicles (which reflect sound waves) that could be administered to a patient to visualize tissues of interest. Faster, please.
