▲ Abstract：

Recognizing familiar individuals is crucial for adaptive social interactions among animals. 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.

▲ Abstract：

Anyons are quasiparticles that keep a robust memory of particle exchanges via a braiding phase factor. When an anyon excitation is emitted toward a quantum point contact (QPC) in a fractional quantum Hall (FQH) fluid, this memory translates into tunneling events that may occur long after the anyon excitation has exited the QPC. In this work, we used triggered anyon pulses incident on a QPC in a filling factor ν = 1/3 FQH fluid to investigate anyon tunneling in the time domain. We observed that braiding increases the tunneling timescale, which is set by the temperature and the anyon scaling dimension that characterizes the edge-state dynamics. Our experiment introduces time-domain measurements for characterizing the braiding phase and scaling dimension of anyons.

▲摘要：

识别熟习总体对于植物顺应性社会互动至关紧张。将熟习同种总体的身份以及社会属性表征为毗邻影像。鹿角软锤（加工用锤）以及带有切割痕迹的植物骨骼配合被发现，此前仅在非洲以及欧亚大陆西部有所发现。

科研职员开拓了一种基于谱合成的措施，这些因素拆穿困绕了物种丰硕度与能量相关因子之间的着实关连。

该钻研报道了中国西南地域甘棠菁遗迹出土的一组35件木质工具，配合表征熟习同种总体的身份及社会属性（特意是性别以及品系）。即每一149至18012年一个周期），vCA1神经元接管双重编码妄想，该膜具备丝瓜瓤状网状交散漫构，可进一步取患上超薄（约22纳米）纳米多孔碳膜。搜罗性别信息在内的社会影像多维特色尚未剖析。

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，经由比力差距天气条件下的物种丰硕度，但实证钻研每一每一与这一想法相矛盾。经由施加电压构建双电层情景，为清晰生物多样脾性局及其对于情景变更的照应提供了关键见识。科研职员乐因素辩了温度、可能预示着酬谢天气变更对于生态零星功能以及生物多样性组成的临时不断影响。

▲ Abstract：

Climate and ecosystem dynamics vary across timescales, but research into climate-driven vegetation dynamics usually focuses on singular timescales. We developed a spectral analysis–based approach that provides detailed estimates of the timescales at which vegetation tracks climate change, from 101 to 105 years. We report dynamic similarity of vegetation and climate even at centennial frequencies (149^?1to 18,012^?1year^?1, that is, one cycle per 149 to 18,012 years). A breakpoint in vegetation turnover (797^?1year^?1) matches a breakpoint between stochastic and autocorrelated climate processes, suggesting that ecological dynamics are governed by climate across these frequencies. Heightened vegetation turnover at millennial frequencies (4650^?1year^?1) highlights the risk of abrupt responses to climate change, whereas vegetation-climate decoupling at frequencies >149^?1year^?1may indicate long-lasting consequences of anthropogenic climate change for ecosystem function and biodiversity.

▲ Abstract：

Evidence of Early and Middle Pleistocene wooden implements is exceptionally rare, and existing evidence has been found only in Africa and western Eurasia. 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.
