C. The First Breakthrough in Understanding SARS

Narrator: This is Science Today. The first critical breakthrough in the rush to understand severe acute respiratory syndrome, or SARS, was made possible by microarray virus screening technology pioneered at the University of California, San Francisco. Arthur Reingold, an infectious disease expert at UC Berkeley, comments on this brand new technology.

Reingold: What that technology allows you to do, is with enormous speed and power, to compare the nucleic acids from a virus or a bacterium or something else with an enormous array of known agents to see if this one is identical to, similar to, or completely different from perhaps thousands or tens of thousands of other known agents.

Narrator:: In just one day, microarray enabled scientists to determine that SARS was in the coronavirus family.

Reingold: So it's a wonderful technology that is certainly helping examine different infectious agents. And it has promise in terms of detection of those agents.
