国防科大磁悬浮试验车时速达到 700 公里
国防科技大学透露,该校磁悬浮团队成功在两秒内,将吨级重的试验车加速至 700 公里/小时,测试速度打破了同类型平台全球记录,成为全球最快的超导电动磁悬浮试验速度。磁悬浮列车速度更快、加速减速更出色,维护成本更低,但建造成本更高,而且不兼容现有铁路设施。至今只有七列磁悬浮列车在运行——中国四列,韩国两列,日本一列。有两条城际磁悬浮线路正在建造,其中一条连接日本东京和名古屋,另一条连接湖南长沙和浏阳。日本实验性磁悬浮列车 L0 Series 曾在 2015 年创造了 603 km/h 的速度记录。 via Solidot

MIT 科学家首次合成有抗癌潜力的天然分子
MIT 与丹娜法伯癌症研究院的科学家合作,首次在实验室成功合成了天然真菌分子“轮枝孢菌素A(verticillin A)”。该分子 50 多年前被首次发现,因其显著的抗癌潜力备受关注,但复杂的结构令其人工合成一直未能实现。研究成果发表于《美国化学会志》,有望开辟一类全新的抗癌药物研发路径。在最新研究中,研究团队不仅实现了轮枝孢菌素A的全合成,还以此为基础设计出多种新型衍生物。初步测试显示,部分衍生物对一种罕见的儿童脑癌——弥漫性中线神经胶质瘤表现出强大的抗肿瘤活性。研究团队从氨基酸衍生物β-羟色氨酸出发,逐步引入醇、酮、酰胺等化学官能团,并精准控制每一步的立体构型。历经16步精密反应,他们最终构建出轮枝孢菌素A分子。 via Solidot
