Caption

 In the DNA rendering to the left, two of the three strand of DNA are "normal;" however, the third strand has a region which can cause cancer.  Professor Armani's research is focused on detecting these regions and understanding what events trigger the change in the DNA.  The technique that she is using relies on a very sensitive nanolaser device which is shown in the electron microscope image to the right.  The laser shown in this picture is smaller than the width of a human hair.
