收藏陆地速度纪录保持者驾驶氢动力赛车突破406英里/小时
JCB Hydromax氢动力赛车在博纳维尔盐滩创下406.320英里/小时陆地速度纪录，由1997年超音速纪录保持者Andy Green驾驶。该车搭载两台800马力发动机，使用与JCB挖掘机相同的量产发动机，以氢气为燃料实现零排放。此次同时打破三项FIA纪录：氢内燃机最快（原185.5 mph）、氢燃料电池车最快（原303 mph）、电动车最快（原342 mph）。
AI能让数学研究变得更"人性化"吗？
数学家Yang-Hui He用神经网络研究卡拉比-丘流形，意外发现AI能识别高维几何的拓扑性质。FrontierMath项目中30位数学家闭门出题，AI一个月内解出约10%。He认为AI正在成为数学研究的通用语言，让不同分支的研究者能真正对话。

OpenAI数学突破被指学术不端，专家称AI只是拼接已有成果
OpenAI的Astra模型声称取得10项数学突破，但多位数学家指出其中关键成果未正确引用已有研究，涉嫌抄袭。 OpenAI在内部测试下一代大模型时发现10个AI生成的数学进展，总token成本仅2000美元。耶鲁大学数学家Steven Miller指出，Astra在解决高维球体填充问题时，将其核心论证当作自己的发现，但该论证最早出现在他2016年的论文中。剑桥大学数学家Francesco Fournier-Facio发现，Astra关于soficity群论的结果同样拼凑了2016年和2019年的已有论文。多位数学家认为，AI的真正能力是超人的耐心——把已有数学文献中的想法拼接起来，而非做出深刻的智力飞跃。OpenAI表示将按学术惯例对论文做小幅更新。
迷幻蘑菇成分能否成为治疗厌食症的关键？
迷幻蘑菇成分psilocybin在厌食症治疗试验中展现潜力，21名女性参与者中3个月时半数症状缓解。研究由伦敦帝国理工等机构进行，发表在《英国精神病学杂志》。无对照组是小样本试点研究的局限。特朗普政府推动美国监管层支持致幻剂研究，FDA或5年内批准。机制可能是增加大脑神经可塑性，打破僵化思维模式。
