Core Viewpoint - Chinese scientists have successfully developed a new "dual-mode" LiDAR system that enhances the three-dimensional perception capabilities of autonomous vehicles, robots, and drones [1][4]. Group 1: Technology Development - The "dual-mode" LiDAR system was developed by a team from Huazhong University of Science and Technology in collaboration with Tsinghua University and Beijing Information Science and Technology University, and published in the top international optical journal "Light: Science & Applications" [1]. - Traditional LiDAR systems are categorized into scanning and flash types, with the former offering high precision but slow speed, while the latter provides fast speed but limited precision. The new system aims to combine the advantages of both [1][4]. Group 2: System Functionality - The core of the new system is a device called "hybrid cascaded translational metasurface," which consists of two layers of specially designed nano-lenses. By altering the polarization state of the incident laser, the system can switch between high-precision scanning mode and flash mode [1][2]. - The hardware allows the system to automatically switch modes based on actual needs, first using flash mode to quickly gather environmental information, then switching to scanning mode for detailed detection of specific areas [2]. Group 3: Implications and Future Applications - This technology successfully integrates the advantages of traditional scanning and flash LiDAR, ensuring high precision and long-distance detection while improving detection efficiency [4]. - The more efficient, flexible, and compact "dual-mode" LiDAR is expected to play a significant role in the fields of autonomous vehicles, intelligent robots, and drones, enhancing their ability to perceive the world [4].

Core Viewpoint - Aging is a major risk factor for various neurodegenerative diseases, including Alzheimer's disease, and is associated with the accumulation of senescent cells that propagate the aging process through paracrine signaling [2] Group 1: Research Findings - The research published in Nature Aging demonstrates that border-associated macrophages (BAM) regulate cognitive aging by inducing paracrine senescence in microglia through migrasome-mediated mechanisms [4][8] - In the early stages of brain aging, BAM acquire senescence-related characteristics, potentially due to prolonged exposure to beta-amyloid (Aβ) [7] - Senescent-like BAM exhibit increased production of migrasomes, which transmit aging-related signals to neighboring cells, particularly microglia, inhibiting their apoptosis and promoting senescence induction [8] Group 2: Intervention Strategies - The research team developed intervention strategies targeting migrasome production by delivering siRNA to block Tspan4, which can improve cognitive deficits in aged mice [8] - These findings suggest that migrasomes are powerful carriers of aging regulatory signals and represent a promising target for Senomorphic therapies, which aim to inhibit the senescence-associated secretory phenotype without affecting cell death [8]

撰文丨王聪 编辑丨王多鱼 排版丨水成文 野火 （ wildfire ） 影响全球碳循环、生态系统、空气质量以及人类健康。在这些影响中，近年来野火对全 球 PM2.5 污染的贡献一直在稳步上升，其中北美地区的增幅最大。2023 年 5 月至 9 月期间，加拿大发生 了严重的森林火灾，过火面积总计达 1500 万公顷 （约占加拿大森林总面积的 4%，是 1983 年至 2022 年年均过火面积的 7 倍多） ，并导致大量碳排放。此外，加拿大野火产生的烟雾不仅飘过北美大陆，导致 美国多地发布空气质量警报，还飘过北大西洋，抵达欧洲和亚洲，这凸显出严重的野火并非只造成局部影 响。 尽管此前已从不同角度对野火产生的 PM2.5 暴露情况进行了研究，并且在以往的研究中也已识别出跨境火 灾污染事件，但此类极端野火对全球空气质量及人类健康的影响仍鲜有探索。 鉴于未来野火预计增多可能带来的持续影响，对这种空气污染的暴露程度以及在全球范围内对健康的影响 程度进行量化，有助于制定应对措施，包括野火监测和预报、灭火、土地管理和大规模景观燃料处理，以 及更广泛的气候缓解措施。 2025 年 9 月 10 日，清华大学 地球系统科学系 张 ...
