Cover Picture: Selenirenium and Tellurirenium Ions (Angew. Chem. Int. Ed. 34/2008)
Two new creations ... in the artificial molecular microworld—selenirenium and tellurirenium ions—float in the cosmic region between the moon goddess Selene, and Tellus, the Earth. H. Poleschner and K. Seppelt describe these molecules in their Communication on page 6461 ff.; the instability of the tellurium compounds parallels the fragile living conditions on our planet. The cover picture makes reference to the poetic names given to tellurium by M. H. Klaproth, and to selenium by J. J. Berzelius.

Rolling circle amplification of DNA is a highly versatile method with broad application in genomics, proteomics, diagnostics, biosensing, drug discovery, and nanotechnology. M. A. Brook, Y. Li et al. summarize the latest developments in this process in their Minireview on p. 6330 ff.
S. L. Buchwald and D. S. Surry describe in their Review on page 6338 ff. the application of dialkylbiaryl phosphane ligands in palladium-catalyzed amination reactions. In the last ten years these reactions have led to many successful syntheses.
In their Communication on page 6362 ff., C. L. Raston and co-workers describe a self-assembled molecular capsule held together by hydrogen bonds. The capsule is disassembled on a rotating disk and can uptake hydrogen upon reassembly.
