Summary:
- Researchers have developed a "glow in the gut" pill that could make colonoscopies optional for some people.
- The pill contains tiny sensors that can detect signs of colon cancer or other gastrointestinal issues and emit a fluorescent glow that can be detected from outside the body.
- This non-invasive approach could provide an alternative to colonoscopies, which are uncomfortable and require preparation, making it easier for people to get regular screenings.
