Methicillin-resistant Staphylococcus aureus, or MRSA, are so uniform in size they look like they were made in a factory. How do the bacteria manage to keep their size so uniform?

The electro-oxidation measurements clearly showed that the adsorbed CO was removed by Cr(VI). Based on the standard reduction potential values for COad electro-oxidation coupled with OHad ,CO(g) oxidation to CO2 and Cr(VI) reduction and [E0 (CO2/COad +OHad) = 0.7~0.8 VNHE (from electrochemical measurements)] , [E 0(CO2/CO) = -0.1 VNHE] and [E0 (Cr2O72?/Cr3+) = 1.35 VNHE], the oxidation of CO to CO2 coupled with the reductive conversion of Cr (VI) to Cr (III) is thermodynamically spontaneous. This redox process achieved not only the cleaning of the Pt electrode surface but also the transformation of toxic Cr (VI) into non-toxic Cr (III).

A new system developed at Oregon State University to improve cancer surgery uses a nanoparticle called a dendrimer to carry a drug into cancer cells, that can set the stage for improved surgery and also phototherapy.

A new NASA study suggests that tropical forests, like this one in Malaysia, absorb more atmospheric carbon dioxide than is absorbed by forests in Alaska, Canada and Siberia.

Schematic illustration of the single-particle spectra modified by spin-orbit coupling. The Rashba-type spin-orbit coupling can lead to a degenerate ring in momentum space for the lower branch of the single-particle dispersion spectra (left). The lower-branch dispersion spectrum under the NIST-type spin-orbit coupling (right) is less symmetric. These differences, as well as the hyperfine-spin dependence of the single-particle dispersion under spin-orbit coupling, give rise to rich physics in these systems.

Low-energy electron microscopy images of the nickel-aluminum surface before and after oxidation. The faint lines before oxidation indicate the atom-high steps that separate flat terrace sections of the crystal surface. As oxidation begins at a point on one terrace, the oxide spreads in elongated stripes along that terrace, pushing steps out of the way and bunching them closer and closer together. Eventually the bunching of steps stops the growth of the oxide stripe and another begins to form, often at right angles, to produce a grid-like pattern.
