Erratic behavior of platinum-group elements along an olivine–Cr-spinel cotectic in sulfide-undersaturated basaltic magma: roles of Cr-spinel and alloys

Scientific Reports
The behavior of platinum-group elements (PGE) in sulfide-undersaturated primitive magmas may be controlled by crystallization of either Cr-spinel, platinum-group minerals (PGM) or olivine.

Diverse Metabolic Control of Phosphoglucomutases by Bisphosphorylated Sugars in Heterotrophic Bacteria

Microbial Physiology
Introduction: Phosphoglucomutases (PGMs) are crucial for bacterial fitness, environmental survival, pathogenicity, and cell envelope stability, making them potential new targets for combating bacterial infection and transmission.

Understanding the Dynamics of Mechanically Interlocked Molecular Systems via Metadynamics Simulations

The Chemical Record, EarlyView.
This Personal Account discusses how molecular simulations help uncover motion, shuttling mechanisms, and kinetics in mechanically interlocked molecules such as rotaxanes and catenanes. Mechanically interlocked molecules, such as rotaxanes and catenanes, display complex internal dynamics and reciprocal motions that are central to their use as artificial

The impacts of large wild grazers on soil carbon persistence are strongly modulated by the environmental context

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Wild animals, particularly large mammalian grazers, can influence ecosystem carbon dynamics and soil carbon sequestration. However, we lack a mechanistic understanding of how wild grazer communities influence soil carbon persistence, specifically in terms of the size of
