Core Insights - Scientists from the Allen Institute and the Howard Hughes Medical Institute have developed a special protein called iGluSnFR4, which serves as a molecular "glutamate indicator" for real-time observation of neuronal communication in the brain [1][2] - This breakthrough aids in deciphering the hidden "language" of the brain and enhances understanding of its complex neural circuitry [1] Group 1: Technological Advancements - iGluSnFR4 addresses the challenge of previously only being able to record signals emitted by neurons, allowing scientists to "hear" the input signals that neurons receive [2] - The protein is highly sensitive to glutamate, enabling the detection of the weakest input signals between neurons, thus providing new pathways for analyzing the complex cascade of electrical activities that support learning, memory, and emotions [2] Group 2: Implications for Neurological Research - Abnormal glutamate signaling is associated with various neurological disorders, including Alzheimer's disease, schizophrenia, autism, and epilepsy [2] - The ability to observe synaptic activity more precisely with iGluSnFR4 allows for deeper investigation into the mechanisms underlying these diseases [2]
选择性补贴调查严重损害中欧经贸合作
Ke Ji Ri Bao· 2025-12-24 00:29
Core Viewpoint - The European Commission's Foreign Subsidies Regulation (FSR) is perceived as discriminatory against Chinese companies, leading to significant operational challenges and financial losses for these firms in the EU market [1][3][4]. Group 1: FSR Implementation and Impact - The FSR, effective from July 2023, mandates companies involved in EU public tenders or mergers exceeding certain thresholds to declare foreign subsidies received [1]. - Since its implementation, the European Commission has received 2,100 declarations but has only conducted three in-depth investigations, all targeting Chinese technology firms in the renewable energy and transportation sectors [2]. - The FSR has reportedly caused direct and indirect losses to Chinese companies amounting to approximately €2.1 billion [3]. Group 2: Legal and Operational Challenges - The lack of transparency in the FSR's enforcement has raised concerns about "black box" governance, with limited information available even for investigated cases [2]. - Compliance with the FSR imposes significant administrative burdens on companies, requiring extensive data collection on foreign subsidies, which can include loans, capital injections, debt relief, and tax benefits [3]. Group 3: Broader Economic Implications - The FSR is seen as damaging to the EU's business environment, creating administrative pressures not only for Chinese firms but also for other international companies operating in the EU [3]. - The regulation is criticized for potentially undermining EU-China economic cooperation, which is vital for energy transition, supply chain security, and infrastructure development [4].

聚酯纤维面料口碑“遇冷”?专家:性能优势突出 “塑料衣物伤身”系误解
Ke Ji Ri Bao· 2025-12-24 00:26
冬季,羽绒服、冲锋衣等衣物消费热度攀升,聚酯纤维作为其核心面料,最近却和塑料瓶画上了等号。 聚酯纤维能稳居"合成纤维第一大品种",与其突出的性能优势密不可分。该面料耐皱性好、弹性佳、尺 寸稳定,兼具良好的电绝缘性能,不霉不蛀。通过技术改性,聚酯纤维可实现仿棉、仿毛等多种质感, 还能被赋予阻燃、抗菌、防紫外线等功能,适配从速干衣到羽绒服的多样穿着需求。 "两者在生产工艺、结构设计和性能标准上存在本质区别。"李德利告诉记者,正如小麦既能做面包也能 酿啤酒,聚酯纤维和塑料瓶也是原料一致,但因加工方式不同而成为截然不同的两种产品。PET经纺丝 工艺拉制成丝状,即为聚酯纤维(俗称涤纶);经吹瓶工艺注塑成型,则成为塑料瓶。从分子特性来 看,制作塑料瓶的PET分子量和黏度更高,能够满足包装的强度需求;而制作聚酯纤维的PET分子量和 黏度相对更低,降低了拉丝难度与生产成本。 "穿塑料瓶"的说法,实则源于再生聚酯纤维的生产流程。太原理工大学纺织系主任、副教授史晟介绍, 目前市场上的聚酯纤维面料主要有两方面来源,一是直接由石油化工原料生产,称为"原生涤纶",二是 用废旧塑料瓶等(主要是PET材质)生产,称为"再生涤纶""环保涤纶 ...
