On the Cover The cover animation, supplied with a popular cell biology text,1 schematically illustrates the processes of condensation and nuclear fragmentation through phagocytosis during the programmed death (apoptosis) of a eukaryotic cell. Animations are now commonly supplied on CDs packaged with textbooks and are used widely in the teaching of molecular processes and other complex biological phenomena. But are they more effective as learning tools than the static color images in the books? In an article on p. 217 of this issue, O'Day compares student retention of concepts after instruction using either animations or static graphics derived from them. 1 From Molecular Cell Biology 4.0, CD-ROM distributed with Molecular Cell Biology, Lodish, H., et al., W.
