The rapid development of deep learning raises a massive demand for computing power. However, traditional siliconbased chips based on the von Neumann architecture with physically separated memory and computing units, are facing critical issues such as the "memory wall", and hence the increase of chip computing power is gradually hitting a bottleneck. To address this problem, researchers have been inspired by the working mechanism of biological brain and proposed a computing-inmemory architecture based on memristors. This novel architecture is expected to achieve several orders of magnitude improvement in energy efficiency and speed over the von Neumann architecture for tasks such as artificial neural networks. It is one of the most promising technologies to achieve ultra-low power consumption and ultra-high computing power. This article first reviews the working mechanisms of various types of memristors, and summarizes the latest device research internationally. Then, the progress on application demonstrations of memristor-based computing-in-memory chips such as neural networks, signal processing, and machine learning are reviewed. The current challenges in this field and further research directions are concluded in the end.

This paper starts from the perspective of pollution reduction and carbon emission reduction, and deeply analyzes the realistic foundation of China's green and low-carbon food production, the main problems faced, and proposes optimization paths. The paper points out that the guidance and support of national policies, the improvement of technological progress and innovation capabilities, and the transformation of market demand are key to promoting the green and low-carbon development of food production. However, there are also issues such as the need for further clarification of policies, the need to strengthen the awareness and ability of producers to reduce pollution and carbon emissions, and technological bottlenecks. To address these issues, the paper proposes optimization strategies including the formulation of a pollution and carbon reduction roadmap, the cultivation of producers' awareness, the strengthening of technological innovation and promotion, and the establishment of a green and low-carbon value realization mechanism. These measures aim to provide theoretical and practical guidance for the green and low-carbon transformation and sustainable development of food production.

This paper provides an overview of the current development status of hydrogen energy highway transportation, rail transit, shipbuilding, and aviation in China. It analyzes the comprehensive performance of hydrogen fuel cell vehicles in China and points out that the challenges faced by Chinese hydrogen energy vehicles are mainly high costs of vehicles and fuel and insufficient refueling infrastructure. However, as China steps into the middle and late stage of urbanization, heavy-load transportation and special transportation with fixed routes provide opportunities for the development of hydrogen vehicles, and family passenger vehicles will become an important direction. Hydrogen energy rail transit will also play a role in areas where electrification is difficult. Ships and aircraft powered by hydrogen compounds will become the focus of shipbuilding and aviation industries. In the future, hydrogen energy transportation should improve planning, promote technological integration and innovation, develop new hydrogen energy transportation travel modes, build a sound policy system, and adopt carbon market mechanism to achieve a new leap.

This article focuses on amorphous matters and reviews recent advances in amorphous materials and physics. More recently, more than 30% of the lunar soil collected by China's Chang'e-5 mission was found to be glassy, further confirming the widespread existence of amorphous matter in the universe. Topological order and inhomogeneity may be hidden behind the seemingly chaotic structure of amorphous materials, so amorphous matters have strange genetic, sensitive and relaxation behaviors, and show a series of excellent physical and chemical properties, such as extreme stability, super-plasticity, super mechanical behavior and excellent soft magnetic properties. The new generation of Zr-based and Fe-based amorphous alloys developed based on order regulation and high flux technology are successfully applied to core components such as folding mobile phone hinges and new energy vehicle motors, indicating that amorphous matters have irreplaceable application advantages. The future development of amorphous matters should focus on introducing a new paradigm of material research, attaching importance to the importance of process innovation, promoting the cross-integration of multi-disciplinary fields, giving full play to the advantages of advanced characterization technology and large scientific devices, and creating a whole-chain innovation model for production, university and research, so as to actively promote the rapid development of amorphous materials and physics, and expand the application of amorphous matters in high-tech fields. Make the future of mankind a better place.

人工智能的飞速发展给生物学研究带来了深远影响，其中，AlphaFold2在蛋白质结构预测领域引发了革命性的突破。评估了AlphaFold2对G蛋白偶联受体（GPCR），结构预测的可靠性，凭借其对蛋白质三维结构的高度准确预测。然而，在实际应用中，AlphaFold2的预测结果并非在所有场景下都足够精确。以GPCR为例，这类重要的药物靶点参与了广泛的生理过程，其结构研究对理解功能机制和药物开发具有重要意义。结果表明，尽管AlphaFold2能够准确捕捉GPCR整体骨架的主要特征，但其预测模型在胞外域与跨膜域的组装、配体结合口袋的形状，以及信号传导界面的构象等方面，与实验解析的高分辨率结构存在显著差异。这些差异限制了AlphaFold2模型在GPCR功能研究和基于结构的药物设计中的应用能力。因此，尽管AlphaFold2为结构预测提供了强大的工具，但其在特定场景下的局限性表明，AI结构预测作为一种辅助工具，尚不能完全取代实验结构生物学，需要联合使用以辅助药理学研究和药物设计。

Gu has closely linked his personal destiny with the future of the nation. His research and efforts have significantly improved the health and quality of life for hundreds of millions of people.

考察美国力推稀土产业链重构的深层动因及最新动态，是确保中国稀土全球战略竞争优势和产业链安全的关键。通过分析美国稀土产业链重构的动因、进展及对中国的挑战，发现美国对中国稀土进口高度依赖、稀土关切上升至国家安全、美国国内稀土强劲消费需求和对中国政策全面转向竞争构成了美国加速稀土产业链重构的动因。目前，美国在稀土资源本土开发与保护、冶炼分离加工布局、高端材料及应用技术创新等全产业链领域的重构成效明显，对中国稀土产业链的全球影响力、中美战略竞争博弈下的抵御经济制裁能力、高端稀土技术创新的外部环境和国际稀土合作的战略空间等方面带来严峻挑战。为此，提出了中国应从提升稀土产业综合竞争力、优化稀土产业结构与布局、提高稀土高端技术应用水平和加强稀土全球化战略布局等方面采取举措，以增强抗衡美国对中国“脱钩”的主动权，抢占稀土“卡脖子”技术制高点，实现从稀土大国向稀土强国目标转变。

China has promised to achieve the "dual-carbon" goal in order to reduce climate warming caused by human-induced CO₂ emissions, accelerate the transition of the electricity system toward renewable energy, and provide impetus to green development. Starting from summarizing the trend of recent studies, this paper encompasses the demand for energy transitions to meet the "dual-carbon" goal, analyzes the environmental problems in the processes of energy transition, and identifies the potential impacts of the production and operation of renewable energy on the environment and ecology. To cope with the challenge of achieving the "dual-carbon" goal, the trends of growth in power generation and energy consumption from 2021 to 2060 are predicted by analyzing the historical growth of renewable energy from 2010 to 2021. In addition, this paper analyzes the demand for land, power transmission, energy storage, and investment for the development of photovoltaic and wind power in China by taking into account the state-of-the-art estimate of photovoltaic and wind power generation. Based on the analysis, it is extrapolated that the renewable growth rate of clean energy in China is insufficient to satisfy the pledges aligning with the "dualcarbon" goal, therefore it is required to overcome the inertia in the energy and economic systems to strengthen the process of energy transition and increase the share of renewable energy in total energy supply. Lastly, a number of suggestions for policy are provided for accelerating the energy transitions to achieve the goal at a low economic cost.
