C. An Insightful Look At Tooth And Bone Tissue

Narrator: This is Science Today. An x-ray microscope originally developed to analyze jet engine components, has been found to also reveal the intricate mineral tissues of teeth and bone. Physicist John Kinney of the Lawrence Livermore National Laboratory says this microscope will give researchers an insightful look at these tissue structures.

Kinney: Because it's non-invasive, we can look at these tissues under a variety of imposed physiological stimuli. For example in the teeth, we can look at them during simulation of cavities. We can look at the bone tissue under mechanical load, so we can see how the tissue deforms or responds adaptively to external situations.

Narrator: And in some cases, such as in the teeth, there's so little tissue there that seeing any of it is highly beneficial.

Kinney: Most samples that we look at, nothing is really ever done to the specimen...so the worst case is we haven't hurt anything, the best case is we've added some value to the information.
