As a crucial human activity， dam construction can profoundly impact the surface hydrology patterns. The Three Gorges Reservoir （TGR）， as one of the largest hydraulic engineering projects in the world， has gained continuous attention for its eco-hydrological effects. However， further investigation is necessary to understand the runoff and social impacts of the TGR on the upper Yangtze River. This study first employed a modified SWAT model to simulate runoff， compared scenarios with and without the TGR， and finally evaluated water supply and demand in the upper Yangtze River. The results showed a significant increasing trend in the surface water area of the upper Yangtze River from 2000-2020. The modified SWAT model performs well in simulating the runoff， with Nash-Sutcliffe Efficiency and Percent Bias improved by 0.04～0.30 and 2～31.90 respectively. Scenario simulation results revealed that the TGR reduced seasonal differences in runoff. During the flood season， the runoff volume at the Yichang station in the scenario with the TGR is lower than in the scenario without the TGR， peaking at 4，500 m3/s. Conversely， in the dry season， the runoff volume of the scenario with TGR is higher， with a maximum increase of 1500 m3/s. The region exhibiting the greatest runoff variations is the Yangtze River’s main stem in the Three Gorges Reservoir region. Besides， the TGR notably alleviated the water supply-demand imbalance in Chongqing during the winter and spring seasons， with a maximum increase of 0.16 in the supply-demand index. This study can contribute significantly to understanding the natural and social impacts of the TGR from the perspective of hydrological and scenario simulation.

Fluid intelligence is a cognitive domain that encompasses general reasoning, pattern recognition, and problem-solving abilities independent of task-specific experience. Understanding its genetic and neural underpinnings is critical yet challenging for predicting human development, lifelong health, and well-being. One approach to address this challenge is to map the network of correlations between intelligence and other constructs. In the current study, we performed a genome-wide association study using fluid intelligence quotient scores from the UK Biobank to explore the genetic architecture of the associations between obesity risk and fluid intelligence. Our results revealed novel common genetic loci (SH2B1, TUFM, ATP2A1, and FOXO3) underlying the association between fluid intelligence and body metabolism. Surprisingly, we demonstrated that SH2B1 variation influenced fluid intelligence independently of its effects on metabolism but partially mediated its association with bilateral hippocampal volume. Consistently, selective genetic ablation of Sh2b1 in the mouse hippocampus, particularly in inhibitory neurons, but not in excitatory neurons, significantly impaired working memory, short-term novel object recognition memory, and behavioral flexibility, but not spatial learning and memory, mirroring the human intellectual performance. Single-cell genetic profiling of Sh2B1-regulated molecular pathways revealed that Sh2b1 deletion resulted in aberrantly enhanced extracellular signal-regulated kinase (ERK) signaling, whereas pharmacological inhibition of ERK signaling reversed the associated behavioral impairment. Our cross-species study thus provides unprecedented insight into the role of SH2B1 in fluid intelligence and has implications for understanding the genetic and neural underpinnings of lifelong mental health and well-being.
