The structure of sodium saccharinate 1.875-hydrate is presented in three- and (3+1)-dimensional space. The present model is more accurate than previously published superstructures, due to an excellent data set collected up to a high resolution of 0.89 Å−1. The present study confirms the unusual complexity of the structure comprising a very large primitive unit cell with Z' = 16. A much smaller degree of correlated disorder of parts of the unit cell is found than is present in the previously published models. As a result of pseudo-symmetry, the structure can be described in a higher-dimensional space. The X-ray diffraction data clearly indicate a (3+1)-dimensional periodic structure with stronger main reflections and weaker superstructure reflections. Furthermore, the structure is established as being commensurate. The structure description in superspace results in a four times smaller unit cell with an additional base centring of the lattice, resulting in an eightfold substructure (Z' = 2) of the 3D superstructure. Therefore, such a superspace approach is desirable to work out this high-Z' structure. The displacement and occupational modulation of the saccharinate anions have been studied, as well as their conformational variation along the fourth dimension.

Eyjafjallajökull's eruption may be a hassle if you had any transatlantic flights planned this summer. For scientists, however, volcanic eruptions are the only way they can obtain samples from deep within the Earth to learn more about our planet, its formation, and its ongoing evolution. Smithsonian Geologist Liz Cottrell helps put this recent eruption into perspective.

A recent study has analysed trade unions’ understanding of the relationship between environmental protection and jobs. It identified four reoccurring themes from interviews with union representatives, which provide insight into how trade union environmental agendas could develop under a greener economy.

The recent recession has prompted the adoption of 'return to growth' policies but the tools used to assess growth often have a narrow economic focus. A new report has assessed current macro-economic models and suggests they need to incorporate the impact that environmental factors can have on the economy, and vice versa, and recommends they should consider limits on resource and material consumption.

The Alang-Sosiya shipbreaking yards in India highlight the inequalities and opportunities of global waste management. The yards, which recycle retired ships from more economically developed countries, have dramatically altered the ecosystems and social structures of the local area. A study looking at stakeholder perceptions analyses different positions on the social and environmental impacts of the yards.

Land use changes over time have altered relations between soils and water cycles throughout the world. Soils have been lost and degraded, and the closely interlinked processes of soils and water have become an urgent issue for European policymakers. This Thematic Issue aims to provide a review of new research into the links between soil and water issues in Europe, including a message that the soil-water links must be considered at their proper spatial scales.

Risk assessments of potential bird mortality caused by planned wind farms should be assessed at the scale of the individual turbine rather than the whole farm, according to new research. It indicated that risk assessments made prior to building are not predicting the actual level of mortality when the farm is built.
