TL;DR: The primary Mn(IV) biooxide formed is a phyllomanganate most similar to δ-MnO2 or acid birnessite, and metal sequestration by the Mn biooxides occurs predominantly at vacant layer octahedral sites.

TL;DR: Sam's Interface for XAS analysis Package (SIXPack) as discussed by the authors is a graphical user interface that allows users simple manipulation and analysis of data, which is particularly useful for analysis of geochemical and environmental systems.

TL;DR: In situ XAS measurements on a bifunctional manganese oxide catalyst with high electrochemical activity for the oxygen reduction reaction (ORR) and the oxygen evolution reaction (OER) demonstrate that the OER activity scales with film thickness, which suggests that the films have porous structure, which does not restrict electrocatalysis to the top geometric layer of the film.

TL;DR: A bacterium is described, isolated from Mono Lake, California, that is able to substitute arsenic for phosphorus to sustain its growth and exchange of one of the major bio-elements may have profound evolutionary and geochemical importance.

TL;DR: It is shown that Mn(II) oxidation by spores of the marine Bacillus sp.
