Diamonds aren’t just a girl’s best friend. And their brilliant sparkle isn’t just made for mesmerizing, they now can aid in cancer detection. Researchers at the University of Australia created tiny synthetic diamonds that light up sections of cancer in MRI scans. This could help locate cancer in areas of the body that are difficult to detect in the early stages, like the brain and pancreas. Though it’s still in the early developmental stages, the future for this technology and its benefits looks promising.
