This year's four articles address topics ranging from the nature of the substructure of the nucleon and the deuteron to the general properties of the nucleus, including its phase transitions and its rich and unexpected quantal properties. They review the present experimental and theoretical understanding of the origin of the spin of the nucleon, the liquid-gas phase transition that occurs at much lower temperatures and densities than those of a quark-gluon plasma in relativistic heavy-ion collisions, the experimental data and theoretical models emerging about very-high-spin states of nuclei, and the history of findings from the deuteron derived from recent electron-deuteron scattering experiments with observed polarizations and other experiments. The authors are not identified.
