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).

Hydroxyapatite is a form of calcium phosphate that has a large number of applications such as bone implants, and drug delivery systems. For each application, the use of calcium based materials is optimized by specifying their geometry, dimension, density, pore size, mechanical strength, purity, and chemical phase.

Secondary electron image of tartrate crystals, sometimes called wine diamonds found on the bottom of a red wine cork. Chemically these crystals are known as potassium bitartrate. They’re formed when tartaric acid, a natural component found in grapes, binds with potassium under cold conditions to form a crystalline salt. (Image collected by Darlene McAllister.)

This is an embryonic nerve cell growing on DNA. In this system DNA is being studied as a tool to dynamically control surface adhesion for cells. Changing the cell behavior at different time intervals allows us to recreate the dynamic growth sequences that occur naturally in regenerating animals like newts.

A 250nm pre-solar grain was isolated from the substrate using FEI Quanta 3D-FEG. The grain is seen on top of the center pillar right under the Pt cap. The process is extremely delicate and precise, thanks to the stability of this FIB system. The sample is from a meteorite somewhere from outer space and the pre-solar grain was first identified in it by its unique isotopic signature.
