Summary:

- Researchers at MIT have developed a new technique that uses light to wirelessly monitor the electrical signals within cells.
- This method, called "optically-interfaced electronics," allows for non-invasive monitoring of cellular electrical activity, which is crucial for understanding how cells function and communicate.
- The technique could have applications in various fields, including neuroscience, cardiology, and drug development, by providing a way to study cellular behavior without physically interfering with the cells.
