Tree-planting is increasingly presented as a cost-effective strategy to maximise ecosystem carbon (C) storage and thus mitigate climate change. Its success largely depends on the associated response of soil C stocks, where most terrestrial C is stored. Yet, we lack a precise understanding of how soil C stocks develop following tree planting, and particularly how it affects the form in which soil C is stored and its associated stability and resistance to climate change.

Article Synopsis
- Analog computation with passive optical components can speed up processing and lower power use, gaining interest due to metasurfaces.
- Recent advancements allow for basic image processing like spatial differentiation using engineered metasurfaces, but future tech needs more sophisticated functions.
- A newly developed ultrathin silicon metasurface can perform mixed spatiotemporal differentiation, enabling fast edge detection of moving objects and aiding the development of compact neuromorphic cameras.*

Article Synopsis
- - The text discusses the development of a passive edge-detection metasurface for image processing that can be dynamically reconfigured by small temperature changes, enhancing its versatility in computing systems.
- - This reconfigurability is enabled by the phase transition of vanadium dioxide, allowing the metasurface to significantly change its response while maintaining high performance metrics like efficiency and polarization-independence.
- - The resulting device is ultra-compact and compatible with large-scale manufacturing, suggesting potential applications in fields like augmented reality, remote sensing, and biomedical imaging.
Distinct, direct and climate-mediated environmental controls on global particulate and mineral-associated organic carbon storage.

Identifying controls on soil organic carbon (SOC) storage, and where SOC is most vulnerable to loss, are essential to managing soils for both climate change mitigation and global food security. However, we currently lack a comprehensive understanding of the global drivers of SOC storage, especially with regards to particulate (POC) and mineral-associated organic carbon (MAOC). To better understand hierarchical controls on POC and MAOC, we applied path analyses to SOC fractions, climate (i.

Optical metasurfaces performing analog image processing - such as spatial differentiation and edge detection - hold the potential to reduce processing times and power consumption, while avoiding bulky 4 F lens systems. However, current designs have been suffering from trade-offs between spatial resolution, throughput, polarization asymmetry, operational bandwidth, and isotropy. Here, we show that dispersion engineering provides an elegant way to design metasurfaces where all these critical metrics are simultaneously optimized.
