SUGP1 Deficiency Leads to Splicing Dysregulation and Reduced piRNA Abundance in Insects
SUGP1 (SURP and G-patch domain containing 1) participates in splice-site recognition through its interaction with SF3B1, and loss of this factor leads to aberrant splicing. While its role in pre-mRNA splicing is well-documented, its impact on small RNA pathways remains poorly und...

Soil moisture is associated with belowground biotic recovery across vegetation restoration systems
Abstract Introduction Karst rocky desertification is a severe form of land degradation in southwest China, where vegetation restoration has been widely implemented to rebuild soil habitat and biodiversity. However, how restoration‐associated changes in soil conditions correspond...

Beyond scenic tea tourism: Reframing therapeutic experience through enabling places
This study conceptualizes therapeutic experience in tea tourism as relationally assembled through material, social, and affective enabling resources. Drawing on a constructivist grounded theory study conducted in Wuyishan, China, we identify nine enabling resources and three enab...

Multi-constraint optimization of riser design for low-pressure casting of a gearbox housing
Dispersed hot spots in ZL105 aluminum-alloy gearbox housings for heavy vehicles make it difficult for conventional riser design to balance feeding reliability and material utilization. A multi-constraint riser design method was therefore developed for an existing mold interface a...

Where does the eroded sediment from hillslopes go in small karst watersheds?
The transport mechanisms of eroded sediment in watersheds have long been a focal point and challenge in the field of eco-hydrology, especially in the context of increasingly frequent extreme climate events globally. However, few studies have focused on the hillslope to watershed...

Ecological industry (EI) for desertification control has become an important pathway for empowering rural industrial revitalization (RIR) and enhancing regional human well-being. However, few studies have explored the driving mechanisms through which EI promote RIR in the context...

In conventional alloys, deformation twins and phase transformations preferentially nucleate within coarse grains. In contrast, deformation-induced nano-twinning and phase transformation in the present work exhibit an inverse grain-size dependence. Notably, the moderately fine-gra...

Rare earth elements (REEs) are essential strategic resources, but their highly similar physicochemical properties make selective separation extremely challenging. Conventional membrane processes generally rely on size exclusion and electrostatic interactions, resulting in insuffi...

Long-term Earth observation has reliably documented vegetation greening, biomass increases, and the mitigation of rocky desertification across the South China karst. However, “greening” alone neither demonstrates an incremental effect of ecological restoration interventions nor s...

Research Progress and Prospect of Ultralow Phosphorus Steel Smelting Technology
Ultralow phosphorus steel (phosphorus content ≤ 0.005%) is a key material for high‐end equipment manufacturing in fields such as nuclear power, marine engineering, and high‐pressure vessels, where phosphorus content control is the core technology. Molten steel dephosphorization i...

Unfolding suppression: statistical learning drives suppression through dynamic attentional states
How does statistical learning drive distractor suppression? A central debate in current research concerns whether the underlying mechanism operates proactively or reactively. To address this issue, we examined the temporal dynamics of distractor suppression across four visual sea...
