Developing global goals for soil health research and action: Report on the “Soil Stars Heligan Summit”, The Lost Gardens of Heligan, UK, March 2026
Soil underpins food production, freshwater, carbon storage and biodiversity, yet over 40% of the world’s soils are now degraded, eroding at rates up to 1 000 times their formation rate. Microbial technologies have matured and can now aid soil recovery, but deployment has lagged due to absent shared targets, harmonized metrics, and coherent reward structures to mobilize sol…

Interfacial microstructure evolution of P91&304 graded composite transition joint during thermal aging and its effect on corrosion behavior
The novel graded composite transition joint (GCTJ) between AISI 304 stainless steel and ASTM A335 P91 steel offers a promising strategy for dissimilar metal integration in high-temperature applications. However, the long-term thermal stability and corrosion resistance of its interfacial zone remain poorly understood. This study investigates the microstructural evolution of…

Detecting and measuring magnetic islands in SIESTA
Nested magnetic flux surfaces typically result in improved performance in toroidal plasmas. Due to the inherent 3D magnetic fields in stellarators, nested flux surfaces are not guaranteed in an equilibrium and this allows for magnetic islands and field-line chaos to be present. In this study, the Scalable Iterative Equilibrium Solver for Toroidal Applications (SIESTA) code…

Experimental observation of non-resonant divertor resiliency in the Compact Toroidal Hybrid experiment
The first experimental measurements of a novel non-resonant divertor (NRD) magnetic topology, to exhaust particles and heat in stellarator plasmas, yields an order of magnitude improvement in strike line resiliency when compared to an island divertor. The NRD concept leverages resilient invariant manifolds near sharp flux surface boundaries in an otherwise chaotic magnetic…

The poloidal fuelling location and its effect on the pedestal and H-mode plasma performance in MAST Upgrade
This paper presents the first results exploiting the high-speed video (HSV) diagnostic on MAST Upgrade to infer neutral deuterium quantities from Dα emission. We detail the process for absolute calibration of HSV which now produces 2D line-of-sight-integrated brightness (ph sr-1 m-2 s-1) of Dα emission in the MAST-U main chamber, showing excellent quantitative agreement wi…

Selective Cr dissolution and redistribution in Fe-Cr during localized FLiNaK salt exposure
Understanding the atomic-scale origins of corrosion in molten fluoride salt environments is essential for developing resilient materials for advanced nuclear and energy systems. Here, we investigate the response of an epitaxially grown Fe-8Cr alloy film to localized FLiNaK salt exposure to elucidate early-stage degradation mechanisms. High-resolution scanning transmission…

Plug-and-Play with 2.5D Artifact Reduction Prior for Fast and Accurate Industrial Computed Tomography Reconstruction
Cone-beam X-ray computed tomography (XCT) is an essential imaging technique for generating 3D reconstructions of internal structures, with applications ranging from medical to industrial imaging. Producing high-quality reconstructions typically requires many X-ray measurements; this process can be slow and expensive, especially for dense materials. Recent work incorporatin…

Manganese Oxides Incubated in Acidic Forest Soil Retain More Organic Carbon Than Iron Oxides
Iron (oxyhydr)oxides are well-recognized contributors to soil carbon (C) storage, but the effects of manganese oxides on carbon storage and transformation are relatively unexplored. Here, the relative capacities of Fe and Mn oxides to bind and stabilize soil organic C were directly compared using an in situ incubation experiment. Quartz sands coated with either poorly crys…
