Pamilo REVIEW 46 Lipid Rifts As a Membrane-Organizing Principle D. Lingwood and K. Simons COVER Crystal structure of a molybdenum oxide nanowheel, 2.6 nanometers in diameter, around a smaller molybdenum oxide cluster. Miras et al. (page 72; related Perspective page 38) used a controlled-flow reactor to show that the central core serves as a transient template for the self-assembly of the nanowheel and is ultimately ejected to yield a hollow finished product.

Hu et al. Potassium channel enrichment in the dendrites of hippocampal basket cells defines a mechanism of neural network function. REPORTS 58 An Unusually Fast-Evolving Supernova D. Poznanski et al. The distinctive properties of this supernova suggest that it is of a kind predicted by theory but not previously observed. 60 Polarization-Induced Hole Doping in Wide–Band-Gap Uniaxial Semiconductor Heterostructures J. Simon et al. A compositional gradient of two semiconductors creates an electronic polarization that ionizes and activates dopant atoms. 64 Translocation of Single-Stranded DNA Through Single-Walled Carbon Nanotubes H. Liu et al. Transfer of DNA by electrophoresis through some carbon nanotubes is accompanied by giant current pulses. 68 Solid Nanoparticles That Catalyze Biofuel Upgrade Reactions at the Water/Oil Interface S.
