FIGURE 1. Images of a cervical-cancer cell were taken using the new imaging technique. Two 3-D images of the cell are shown at left; 2-D slices are seen at right. The green structures represent the nucleus, which surrounds the nucleolus (not visible in these images). The red areas are unidentified cell organelles.
