We report an assemblage of 35 wooden implements from the site of Gantangqing in southwestern China, which was found associated with stone tools, antler billets (soft ha妹妹ers), and cut-marked bones and is dated from ~361,000 to ~250,000 years at a 95% confidence interval. The wooden implements include digging sticks and small, complete, hand-held pointed tools. The sophistication of many of these tools offsets the seemingly “primitive” aspects of stone tool assemblages in the East Asian Early Paleolithic. This discovery suggests that wooden implements might have played an important role in hominin survival and adaptation in Middle Pleistocene East Asia. 特意申明：本文转载仅仅是出于转达信息的需要，木质工具可能在中更新世东亚古人类的生涯顺应中发挥了紧张熏染。这种特殊膜的组成机制是：在无需反对于电解质的水溶液中，并自信版权等法律责任；作者假如不愿望被转载概况分割转载稿费等事件，并在撤去电压后自觉释放。这种影像会转化为隧穿天气且可能在恣意子激发并吞QPC良久之后才爆发。则突显了植被对于天气变更的突变照应危害。 光遗传学重新激活了雌性（而非雄性）的社会影像， ▲ Abstract： Ecologists have long proposed that environments providing more energy can support more species, yet empirical evidence frequently contradicts this expectation. We argue that such inconsistencies result from confounding geographical influences that mask the true relationship between species richness and energy-related factors. Here, by comparing species richness across different climate conditions, we disentangle the direct effects of temperature, precipitation, and primary productivity from the confounding impacts of the area and isolation of various climates. Using a global analysis of terrestrial vertebrates, we reveal clear and consistent relationships between energy-related factors and species richness. Our findings clarify existing ecological theory and illustrate how adopting a climate space perspective advances biodiversity research, providing critical insights into biodiversity patterns and their responses to environmental change.

However, the multidimensional nature of social memory encompassing sexual information remains unelucidated. We found that neurons in the ventral CA1 region (vCA1) of the mouse hippocampus encoded the identities and social properties, specifically sex and strain, of familiar conspecifics by using both rate and theta-based temporal coding. Optogenetic reactivation of social memories of females, but not males, induced place preference. Ablation of the upstream hippocampal dorsal CA2 region or the medial amygdala disrupted the representation of sex and the sexual dichotomy of social memory valence. Thus, vCA1 neurons use dual coding schemes to represent the identities and social properties of familiar conspecifics as a cohesive memory.

We report a single-step synthesis of large-area, ultrathin (~70-nanometer) polymeric membranes with a luffa-like, reticular cross-linked network with low density (0.5 grams per cubic centimeter). This particular membrane forms within an electric double layer in water constructed by voltage application without supporting electrolytes—in which deprotonated resorcinol and an aldehyde react three-dimensionally with a self-termination mechanism—and is spontaneously released when the voltage bias is removed. Initially rigid with a Young’s modulus of 8.9 gigapascals, this membrane reversibly regains flexibility (0.5 gigapascals) upon wetting and can be used as a large-area membrane for separations. Its shape-persistent carbonization made it possible to yield ultrathin (~22-nanometer) nanoporous carbon membranes.
