I love these kinds of science/tech/medical stories, where an innovation makes life better.
Researchers at the University of Illinois at Urbana-Champaign and Washington University in St. Louis have developed a surgical camera inspired by the eye of the morpho butterfly. The tiny camera, connected to the goggles a surgeon wears, sees infrared signals given off by tumor-binding dyes so that the surgeon can find and remove all of the cancerous tissue.
The camera was tested in mice and in human patients with breast cancer. The study was published in the journal Optica.
