Is March Madness always the same?

DURHAM, N.C. — Why is it that the same teams seem to dominate the annual men’s collegiate basketball tournament? For that matter, why does the same small group of institutions seem to top annual best-college rankings?
According to a theory d…

Detecting esophageal cancer with light

DURHAM, N.C. — A tiny light source and sensors at the end of an endoscope may provide a more accurate way to identify pre-cancerous cells in the lining of the esophagus.
Developed by biomedical engineers at Duke University and successfully t…

Light on silicon better than copper?

DURHAM, N.C. — Step aside copper and make way for a better carrier of information — light.
As good as the metal has been in zipping information from one circuit to another on silicon inside computers and other electronic devices, optical sig…

New Microprobe Shines Light Below Organ Wall Surfaces

Photonics and ultrasound engineering researchers from Duke University and The George Washington University have collaborated to design an optical scanner miniaturized enough to be inserted into the body, where its light beams could someday detect abnormalities hidden in the walls of the colon, bladder or esophagus. The experimental device, called an “electrostatic micromachine scanning mirror for optical coherence tomography,” is described in an article published in the April 15, 2003, issue of the research journal Optics Letters.
