Research roundup: 6 cool science stories we almost missed 研究综述：6个我们差点错过的酷科学故事

Incan sacrificial victim ("Boy of Cerro El Plomo") died from blunt force trauma via star-shaped mace, not freezing as previously believed; CT scans revealed full stomach and vomiting, with no cold-related injuries Two Incan girls previously thought to have died by strangulation actually showed intact hyoid bones and neck marks consistent with textile clothing, not strangulation Ancient Egyptian princesses (Ita, Khenmet, Itaweret) from Dahshur pyramid complex exhibited pronounced upper-limb muscl 印加祭祀受害者（“塞罗埃尔普隆博男孩”）死于星形锤造成的钝器创伤，而非此前认为的冻死；CT扫描显示其胃内容物充盈且存在呕吐迹象，未发现与寒冷相关的损伤 两名此前被认为死于勒杀的印加少女实际舌骨完好，颈部痕迹更符合纺织品衣物所致，而非勒杀 来自达舒尔金字塔群的古埃及公主（伊塔、肯梅特、伊塔韦雷特）表现出显著的上肢肌肉发育和愈合性骨折，与习惯性射箭和武器使用相符，证明弓和锤是实用工具而非象征性陪葬品 新加坡国立大学研究人员开发出两栖仿生蟑螂，其3D打印氧气罐利用二氧化锰催化剂和过氧化氢将氧气直接输送至气管球，实现水下导航以执行搜救任务 仿生昆虫利用生物肌肉进行运动，在类似灾区探索任务中比全人工微型
