摘要：Memory engrams are formed through experience-dependent plasticity of neural circuits, but their detailed architectures remain unresolved. Using three-dimensional electron microscopy, we performed nanoscale reconstructions of the hippocampal CA3-CA1 pathway after chemogenetic labeling of cellular ensembles recruited during associative learning. Neurons with a remote history of activity coinciding with memory acquisition showed no strong preference for wiring with each other. Instead, their conn...

摘要：Piezoelectricity is primarily observed in noncentrosymmetric insulators or wide bandgap semiconductors. We report the observation of the piezoelectric (PE) effect in half-Heusler (HH) narrow-bandgap semiconductors TiNiSn, ZrNiSn, and TiCoSb. These materials exhibit shear PE strain coefficients that reach similar to 38 and 33 picocoulombs per newton in ZrNiSn and TiCoSb, respectively, which are high values for noncentrosymmetric nonpolar materials. We demonstrated a TiCoSb-based PE sensor with ...

摘要：Antarctic ice shelves buttress the grounded ice sheet, mitigating global sea level rise. However, fundamental mechanical properties, such as the ice flow law and viscosity structure, remain under debate. In this work, by leveraging remote-sensing data and physics-informed deep learning, we provide evidence over several ice shelves that the flow law follows a grain size-sensitive composite rheology in the compression zone. In the extension zone, we found that ice exhibits anisotropic properties...

摘要：Distributed across two continents and thousands of islands, the Asian tropics are among the most species-rich areas on Earth. The origins of this diversity, however, remain poorly understood. Here, we reveal and classify contributions of individual tropical Asian regions to their overall diversity by leveraging species-level phylogenomic data and new fossils from the most species-rich Asian palm lineage, the rattans and relatives (Arecaceae, Calamoideae). Radiators (Borneo) generate and distri...

摘要：Although the global economy requires geological resource mining, production has substantial environmental impacts, including the use of regional available water. In this study, we shed light on the global production capacity of 32 mined geological resources, considering regional water availability as a constraint. We found that current resource mining greatly exceeds regional water constraints for several, notably copper (37% of current production exceeds available water capacity) in 2010. Cha...
