这并非是马斯克首次对这批美国司法部最新公开的文件作出回应。此前相关消息曝光后，马斯克迅速在 社交平台X上回应称，自己与爱泼斯坦的通信往来"极少"，且"多次拒绝"前往爱泼斯坦的私人小岛，"但 我很清楚，与他的部分邮件往来可能会被曲解，并被反对者利用来诋毁我的声誉"。 此外，马斯克还在另外一条帖子中暗示克林顿、比尔·盖茨等人"有罪"。有网友发文称，美国微软公司 创始人比尔·盖茨、特朗普首个总统任期内的顾问斯蒂芬·班农、美国职业社交网站领英联合创始人里德· 霍夫曼、美国前总统比尔·克林顿等都出现在爱泼斯坦案文件中，却保持沉默，只有马斯克呼吁起诉， 这是为什么？马斯克转发这条帖子并回复称，"因为他们有罪"。 据美媒此前报道，多年来，好莱坞、华尔街、华盛顿及时尚界人士反复强调自己"并不是很了解"爱泼斯 坦，称与其往来短暂、出于职业原因或礼节，甚至对其"心生反感"。然而，新公布的文件所呈现出的邮 件往来、邀约记录与资金轨迹，却与这些说法形成明显反差。另外，此次公布的文件依然存在内容被涂 黑甚至干脆未予公布的情况。美国民主党众议员罗希特·康纳表示："拒不公布这些文件，只会庇护涉案 的权贵人士，损害公众对国家机构的信任。" ...

研究团队在实验中设置了"多只工蚁照料"和"少数工蚁照料"的对比组。实验结果显示：白蚁幼蚁的发育 和品级分化，完全由工蚁的抚育强度决定——抚育过多会导致保幼激素累积，抑制卵巢和翅芽发育，最 终成为不育的"工蚁"；而抚育适度时，幼蚁才有可能发育为生殖蚁。这一结果最终验证了白蚁"抚育行 为—激素调控—品级分化"的发育链条，揭示了社会性演化的驱动因素，为解释社会性昆虫的分工现象 提供了核心证据。 该研究提出的"营养—信号通路协同演化"模型，不仅解释了白蚁这一"超个体"社群如何实现稳态运行， 更为学界理解包括其他昆虫，乃至哺乳动物在内的社会性演化普遍规律，提供了一个强大的全新理论框 架。这项研究标志着社会生物学进入一个可在明确生态背景下追溯与解析基因演化机制的新阶段。 中国工程院院士吴孔明认为，这项工作是动物社会性演化研究领域的一项里程碑式成果，首次将生态适 应（营养缺乏的朽木环境）、遗传变异（基因组收缩与关键基因功能演化）和发育可塑性（信号通路基 因表达的重组）三者系统性地整合在一起，为"环境—基因—表型"的协同演化提供了一个完整的案例。 来源：光明日报 本报广州2月1日电（记者雷爱侠、吴春燕） 日前，华南师范大学生 ...

科技日报记者 夏凡 通讯员 邵一鸣 记者2月1日获悉，宁波大学物理科学与技术学院教授陈王华团队联合宁波工程学院和宁波东方理工大学 团队，在全固态锂电池负极材料领域取得重要进展。该研究通过模拟自然界的"呼吸"机制，首次研发出 一种具有三维"透气"结构的硅纳米线负极，为开发硅负极全固态锂电池提供了新的技术路径。相关成果 日前发表在国际能源材料期刊《能源存储材料》上。 全固态锂电池因更高的安全性、更强的能量密度以及更出色的循环性能，被科学界和产业界公认为下一 代电池技术的"终极目标"。硅凭借超高的理论容量和良好的化学兼容性，被视为全固态电池中最具潜力 的负极材料之一。然而，硅在充放电过程中巨大的体积膨胀会导致严重的机械应力、界面脱离及电化学 性能快速衰减，这限制了其在大规模锂电池中的实际应用。 "如果把锂电池比作一个储能仓库，硅就是公认的'超级搬运工'，它的储能潜力巨大，是传统商用石墨 负极的10倍。然而，这位'巨人'性格极度暴躁：在充电吸收锂离子时，硅的体积会剧烈膨胀3倍以上， 随着充放电循环，硅会像不断吹大又缩小的气球，最终因'体力不支'粉碎脱落，电池寿命也会随之'猝 死'。"陈王华介绍。 如何让硅在坚硬的固态 ...
