Narrator:       This is Science Today. At the National Center for X-Ray Tomography, located at the Lawrence Berkeley National Laboratory's Advanced Light Source, researchers are lining up to get a chance to use the facility's 72-foot long microscope. Carolyn Larabell of the University of California, San Francisco, who directs the center, says it's the first facility of its kind that's devoted to biomedical research.

Larabell:        We have a long list of things we want to look at, as well as a long list of people who want to use the microscope. A wide range of studies, including studies of breast cancer, human lymphocytes, studies of viral infection of human cells.

Narrator:       With funding from the National Institutes of Health and the Department of Energy, Larabell says the center avails their technology to the biological community.

Larabell:        So, we are available through a proposal process to all of the biologists throughout the United States and the world to bring projects to the microscope.
