Scientists have created what they say is the world’s first “living laser” capable of producing a laser beam, which could one day be used to activate drugs inside the human body.
Researchers at the Wellman Centre for Photomedicine at Massa-chusetts General Hospital in the US used a cell from a human kidney and genetically engineered it to produce light in the same way as a jellyfish and flooded it with blue light. This caused a green laser to be beamed out of the other end that was visible to the human eye, the Daily Mail reported here.
