柯林斯及其團隊訓練了一個生成式人工智能模型,用來辨識已知抗生素的化學結構,使演算法能學習哪些特徵能殺死細菌。研究人員其後利用AI篩選超過4,500萬種化學結構,以評估它們對兩類細菌的作用:
我国是世界上人口老龄化程度较高的国家之一。截至2025年末,60岁及以上人口约3.23亿人,占总人口的23%,其中65岁以上人口约2.24亿人,占总人口的近16%,且老年人口呈现增长态势。当前,养老服务领域还存在一些现实挑战:家庭结构小型化导致年轻一代养老压力增大;养老服务属于人力密集型行业,养老人才供给不足;部分养老机构运营成本高,价格高昂,老年人难以承受;养老服务质量有待提高,难以贴合老年人需求等。如何让数量庞大的老年人老有所养、安享晚年,是一项重大的民生课题。
