"Ultrasound can image centimeters deep in opaque mammal tissue, allowing non-invasive imaging of whole organs. This gives us information about how cells behave in their natural environment, something ...

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 ...

From releasing drug payloads to powering implants, acoustic waves offer noninvasive strategies to target malignant cells and ...

Pacemakers have become smaller and more sophisticated over the decades, but they still share one defining characteristic: They must enter the body to operate. Researchers at the Massachusetts ...

While medical centers use ultrasound daily, so far this technology has not been capable of observing body tissues at the scale of cells. Physicists have now developed a microscopy technique based on ...

Ultrasound is one of the most widely used imaging techniques in medicine, but up until recently it hardly played a role in imaging the tiniest structures of our bodies such as cells. “Clinical ...
