The 26S proteasome operates at the executive end of the ubiquitin-proteasome pathway. Here, we present a cryo-EM single particle structure of the Saccharomyces cerevisiae 26S proteasome at a resolution of 7.4 Å or 6.7 Å (Fourier-Shell Correlation of 0.5 or 0.3, respectively).

False-coloured image of T4 bacteriophage incubated with a de novo-designed self assembling peptide fibre (SAF). Small peptides, 28 amino acids long, self assemble to form fibres ~80 nm wide and ~40 microns long. The T4 tail striation distance was being used as a high-resolution calibrant to register the lateral striations of the fibre.

Microparticles formed by nanostructured hydroxyapatite crystals and biopolymers. Hydroxiapatite (HA) is one of the most biocompatible ceramics because it is similar to the mineral constituents of human bone and teeth. This composite are interesting biomaterial for medical applications, especially for bone replacement. The colors were obtained using the software FEI Company

Capturing and storing carbon dioxide (CO2) and other greenhouse gases deep underground is one of the most promising options for reducing the effects of energy production on the earth. Scientists at PNNL are using electron microscopes to understand the reaction of CO2 and minerals found underground. SEM image shows the aftermath of fayalite reacting with supercritical CO2 to form siderite, thereby capturing the CO2 in a solid, stable form. Research was funded by the U.S. Department of Energy.

The arrays of nickel nanowires have been produced by electro-deposition of nickel into the pores of porous alumina membranes. The membrane has been resolved by chemical etching and free standing nanowires perpendicular to a substrate have been obtained. Due to their ferromagnetic properties, the nanowires have possible applications in high density magnetic recording media. The picture shows a cross section view of the nickel nanowire array.

Gold nanoparticles on an ITO surface under a layer of graphene. The structure of the ITO, which is transparent in optical microscopes, is visible in blue. The nanoparticles are clearly visible through the very thin layer of graphene. Sample prepared by Joanna Niedziolka-Jönsson for this article: dx.doi.org/10.1063/1.4867167
