A new theory, that explains how light and matter interact at the quantum level has enabled researchers to define for the first time the precise shape of a single photon.

When you ask what a photon would "see," you are assuming that it's possible for something to interact with a photon and for the photon to experience that interaction somehow.

New CT technology allows for a comprehensive, simultaneous evaluation of lung structure and function, something not possible with standard CT, according to a new study.
