据英国《新科学家》杂志网站12日报道，德国与英国科学家拟携手利用欧洲首台百亿亿次级（E级）超 级计算机"木星"，模拟完整人脑。这一突破性尝试有望揭开大脑运作的深层奥秘，并为药物研发提供全 新测试平台。 长期以来，科学家多聚焦于大脑的局部区域，通过建模来解析特定功能。将各个脑区整合进统一模型， 以观察整体协同机制，这一愿景始终未能实现。如今，随着计算能力的飞跃，这一愿景正逐渐成为现 实。 当前最先进的计算机已迈入E级超算阶段。全球目前仅有4台达到此级别的机器。其中，"木星"于去年9 月在德国尤利希研究中心正式启用，是欧洲首个跻身该行列的超级计算机。 相较于此前对果蝇等小型生物大脑的模拟，如此规模的全脑仿真将带来质的飞跃。正如大语言模型如 ChatGPT所展现的那样：当系统足够庞大时，会涌现出小系统中根本不存在的新功能。 此次用于"木星"的模型将基于大量实验数据构建，包括单个神经元拥有的突触数量、放电频率等生物学 细节，力求贴近真实人脑结构。该全脑模拟将使科学家得以验证一些以往无法检验的核心理论，例如记 忆如何形成。他们可通过向虚拟大脑输入图像，观察其反应，并追踪记忆痕迹随脑规模变化的过程。此 外，这种技术还可用 ...

Core Viewpoint - The research conducted by the Chinese Academy of Sciences reveals that the large impact event approximately 4.25 billion years ago in the South Pole-Aitken Basin not only created the largest crater on the Moon but also caused the loss of certain volatile elements from the Moon's deep material due to high-temperature conditions [1][2]. Group 1: Impact of Large Collision - The South Pole-Aitken Basin is the largest impact basin on the Moon, and the samples collected by the Chang'e 6 mission provide critical insights into the effects of this large impact event [1]. - The study highlights that asteroid impacts have been the primary external force shaping the Moon's surface since its formation, leading to significant changes in its topography and chemical composition [1]. Group 2: Isotope Analysis and Findings - The research team performed high-precision potassium isotope analysis on the basalt samples returned by Chang'e 6, revealing a significantly higher proportion of the heavier potassium isotope (K-41) compared to samples from the Moon's near side [2]. - The study concluded that the early large impact event altered the potassium isotope composition of the Moon's deep mantle, with the high-temperature and high-pressure conditions during the impact causing the lighter potassium isotope (K-39) to escape, resulting in a relative enrichment of K-41 in the remaining material [2]. Group 3: Implications for Lunar Evolution - The loss of volatile elements due to the impact may have further suppressed volcanic activity on the Moon's far side, providing key scientific clues for understanding the impact of large collisions on lunar evolution [2]. - This research helps explain the geological evolution differences between the Moon's near and far sides, offering insights into the Moon's overall geological history [2].

目前缺乏针对河流输送垃圾量的长期观测。德国波恩大学团队在科隆部署了一个漂浮垃圾收集器，监测 莱茵河2022年11月19日至2023年11月18日期间输送的垃圾。该收集器可捕获水面漂浮的垃圾以及水下最 深80厘米的垃圾，每日能过滤日均河流量的约0.08%。所有大于1厘米的垃圾均被收集、称重并分类。 收集器共捕获17523件垃圾，总质量约1955千克（不含水分重量）。约70%的单件垃圾为塑料制品，其 质量仅占垃圾总量的15%。研究发现，56%的捕获垃圾来自个人消费者，其中约28%的垃圾与食品或饮 料有关。其他主要垃圾来源包括烟花（占总量的10.7%）和烟草相关废弃物（占总量的6.5%）。 根据该结果推算，莱茵河每年向北海输送3010—4707吨垃圾，其中塑料垃圾占了446—697吨。 新一期《通讯·可持续性》杂志发表的一项研究显示，莱茵河每年向海洋输送的大型垃圾（尺寸大于25 毫米的垃圾碎片）估计达3000—4700吨。该上限推算自与科隆公民科学家合作连续监测12个月的数据， 是之前某些估算值的250倍以上。 ...
