“Scientists have built a tiny gut explorer robot to detect and potentially treat a lethal common cancer, in the latest advance in the fast-evolving field of medical robotics.

The machine makes 3D scans of the colon that were previously impossible, using its mussel shell-like shape to roll through the digestive system when guided by a magnet outside the body. The innovation could boost detection of bowel cancer, which is treatable in its early stages but is the second-biggest cause of cancer deaths worldwide.”
