Kaneda and co-workers in their Communication on page 1238 ff. The reaction proceeds under an atmosphere of O2 in the presence of a homogeneous palladium catalyst with water as the oxygen source. Artistically, the reaction is depicted as moving through an hour glass as the reactants are transformed into product. DNA–Protein Conjugates DNA–protein conjugates combine the self-assembly properties of nucleic acids with the large repertoire of protein functionality. C. M. Niemeyer describes in his Review on page 1200 ff. how such conjugates can be prepared and what applications they have. Nanostructures In their Communication on page 1218 ff., M. E. van der Boom et al. report the assembly of gold nanoparticles with a series of pyridyl-containing linkers. The molecular geometries of the linkers are expressed in the structural and optical properties of the AuNP assemblies. Chemical Dynamics S. Lee, Y. S. Choi, S. K. Kim et al. describe in their Communication on page 1244 ff. the photodissociation of diazirine in the S1 state in which the two C N bonds of the excited diazirine break in a stepwise manner.
