秀山县"红领巾巴士"由团秀山县委、秀山县少工委发起，多部门合力打造，自2022年10月开通首条线路 以来，已覆盖城区到农村小学14条线路，部分线路还能直接开进校内接送学生，守护孩子安心上下学， 同时破解了中小学校门口拥堵难题。 "'红领巾巴士'的最大特色是根据学校统计的乘车需求，并结合广大学生的家庭住址分布，每所学校精 心设计不限于1条的定制专线，将家与校串联，解决常规公交未覆盖区域学生的出行问题。"负责具体运 营"红领巾巴士"的秀山万方公司副总经理胡宇介绍，仅迎凤小学官湖校区，就开通了3条专线。 截至目前，秀山县已开通14条"红领巾巴士"，其中3条为农村线路，城区校园覆盖率超过80%，每天18 辆公交车精准对接各校上下学时间，学生乘车可选择月票和两元上车通票制。 "以前我每天下午总要挤时间从店里赶去接孩子，接完又带回店里等待下班，如今孩子自主乘车回家， 我也能安心工作。"麓湖郡小区学生家长李秀丽说，"这公交真正开进了家长心坎里。" "之前很多学生都是家长骑摩托车、电动车接送，冬冷夏热，还不安全。"龙池镇干川小学校长李黎明 说，现在离学校远的38名学生坐上了有空调的公交车。 1月14日下午，在重庆市秀山土家族 ...

Core Viewpoint - A significant breakthrough in semiconductor technology has been achieved by a research team at Xi'an University of Electronic Science and Technology, which enhances chip heat dissipation efficiency and overall performance by transforming the "island-like" connections between materials into atomically smooth "thin films" [1][2]. Group 1: Research Breakthrough - The research team developed a new growth mode for aluminum nitride (AlN) layers, changing them from rough "polycrystalline island-like" structures to highly ordered "single crystal thin films" [2]. - The new "ion implantation induced nucleation" technique allows for precise and uniform growth, significantly reducing interface defects and thermal resistance [2]. - Experimental data shows that the new interface thermal resistance is only one-third of that of the traditional "island-like" structure, marking a major advancement in the field [2]. Group 2: Performance Improvement - The GaN microwave power devices produced using this innovative AlN thin film technology achieved output power densities of 42W/mm and 20W/mm in the X-band and Ka-band, respectively, improving international performance records by 30% to 40% [2]. - This advancement allows for increased detection range without changing chip size and enables communication base stations to achieve longer signal coverage with lower energy consumption [2][3]. Group 3: Broader Implications - The technology's benefits will gradually be realized by the general public, potentially enhancing mobile signal reception and battery life in remote areas [3]. - The breakthrough provides a scalable "universal integration platform" for high-quality integration of various semiconductor materials, offering a replicable model for global challenges in the semiconductor industry [3]. - Future research may explore replacing AlN with diamond, which could further enhance power handling capabilities by an order of magnitude, indicating ongoing exploration of material limits as a driving force in semiconductor technology advancement [3].

AI可以生成"思念""牵挂"等词汇，甚至组合出看似深情的句子，但它永远无法体会词语背后真切的生命 体验。深圳那位语文老师的课堂上，高中生用"妈"字证明自己不是AI，这个简单的字背后，是母亲日常 的照顾、是离家时的叮咛，是"父母在世时，世界的风雨都绕过我"的安稳。这种情感不是逻辑推演的结 果，而是刻在生命里的记忆。AI可以模仿写下"乡愁"主题的文字，却永远不懂余光中心里藏着的牵挂。 当我们在课堂上品读这些文字，在写作中倾诉心声，本质上是在锤炼感知情感、真诚表达的能力。 文字的魅力，藏在其蕴含的生活意味中。AI的表达基于海量数据的归纳，追求精准与高效，却难以理 解人类生活中那些"不合逻辑"的细腻感知与独特体验。有高中生选"急"，因为AI不懂患者在医院等待检 测报告时，每一分钟都被焦虑浸泡的沉重；也有学生选"慢"，因为人们愿意与喜欢的人慢慢相处，在一 束光的倾斜中感受时光的温柔。语言文学教会我们的，正是从平凡生活中感知和发现意义的能力。 文学的根基，同样蕴藏在延续至今的文脉。AI可以模仿古文的句式，复刻诗词的格律，甚至统计经典 作品的用词频率，但它无法理解文字背后承载的历史记忆、文化基因与民族精神。从《诗经》"关关 ...

题目编写审核流程。北京大学化学与分子工程学院供图 2025年年末，北京大学化学与分子工程学院的一间教室里，174名大二学生正面对一场特殊的期中考试。试 卷上，晶体结构的精细解析、反应机理的深度推演、物化性质的定量计算等硬核题目扑面而来，而考生们 的"竞争对手"并非同窗，而是ChatGPT、Gemini、DeepSeek等当下最顶尖的人工智能大语言模型。 这场"云端对决"的背后，是北大青年科研团队在去年12月打造的SUPERChem项目——一套包含500道高难 度试题的基准测试集，旨在用"北大标准"丈量AI在化学领域的真实推理能力。 在团队成员、北京大学化学与分子工程学院2020级博士研究生黄志贤看来，设计这套高难度题库的目的并 不是为了证明AI不行，而是搞清楚AI到底"懂不懂化学"，为AI的发展提供更清晰的参考。 在AI大模型技术爆发式发展的当下，人们似乎已经习惯向AI索取答案，"AI能解决各类复杂问题"的声音不 绝于耳，而这群年轻的科研人员选择用最严谨的方式，对技术热潮进行一次冷静的追问。 前沿模型在SUPERChem上的表现。北京大学化学与分子工程学院供图 "在AI发展过程中留下自己的痕迹" 黄志贤在日常 ...

Core Insights - A new study published in the journal "Cell" introduces a novel approach to precisely degrade and clear pathogenic proteins in living organisms using a supramolecular targeted chimeric (SupTAC) technology, developed by a research team from the Chinese Academy of Sciences [1][4] Group 1: Technology Overview - SupTAC technology allows for programmable and spatiotemporally controlled degradation of proteins, enabling targeted action at specific organs like the lungs or liver [2][3] - The core of this technology is a sophisticated "supramolecular ball" that can be functionalized on its surface to recruit target proteins and E3 ubiquitin ligase, facilitating precise regulation of protein ubiquitination and degradation [1][2] Group 2: Mechanism of Action - The technology employs a "chemical cage" design that can be activated under specific conditions to release the supramolecular ball, allowing it to function at targeted sites [2][3] - SupTAC achieves spatial targeting by recognizing specific endothelial cells in different organs, which is crucial for avoiding damage to normal proteins in healthy tissues [3] Group 3: Research Findings - The study demonstrated that SupTAC successfully targeted and degraded long-chain acyl-CoA synthetase in the lungs, significantly inhibiting lipopolysaccharide-induced ferroptosis and inflammatory responses in lung cells [3] - The research highlights a six to seven-year development process, indicating the complexity and innovation of the technology, which faced rigorous scrutiny during the peer review process [3] Group 4: Future Applications - Although still in the methodological development stage and not yet in preclinical research, the technology shows promise for applications in treating tumors, lung inflammation, and related diseases [4] - The research team plans to continue expanding the platform for basic research while exploring pathways to translate these findings into applications that benefit public health [4]

中国政法大学端升楼内，悬挂着一块写有"课比天大"的横匾，3000多公里外的新疆政法学院里，也有一 块同样的牌匾。题写新疆政法学院内这幅横匾的，正是中国政法大学"银龄教师"于健。 古稀之年的于健关注学生的成长以及当地社会的发展进步，他笑称自己总是闲不住，争分夺秒地将一腔 热情投入援疆事业。四年来，于健还应邀为克拉玛依市委宣传部及有关市直单位、克拉玛依开放大学、 克拉玛依中小学与和田地区墨玉县各高中等义务开办讲座。 于健与新疆结缘，还要从1957年说起。 2006年，一部讲述中国第一代石油人勘探、开发、建设克拉玛依油田的电视连续剧《西圣地》，让许多 人了解到那段艰难又光辉的岁月，而于健的父亲正是剧中描绘的那些石油人之一。"父亲是1957年北京 石油学院的首届毕业生，毕业时他奔赴祖国最需要的地方，开发克拉玛依油田。油田的第一口生产井， 就是我父亲带着1436功勋钻井队打的。" 1975年，于健父母又响应国家号召，从大西北转战大东北，举家前往辽河油田支援建设。直到2021年， 已经退休10年的于健收到一封来自中国政法大学的邮件，得知教育部等正在开展"银龄讲学计划"，邀请 高校退休教授支援中国石油大学（北京）克拉玛依校 ...
