实验显示，微重力环境可能对精子健康构成不小的挑战。研究团队从 15 位男性身上收集了精子样本，将每个样本一分为二：一半留在地球，另一半则送上进行抛物线飞行的飞机，模拟微重力环境进行实验。结果发现，处于微重力条件下的精子样本，其运动能力（活力）与存活率显著下降，虽然微重力环境不会直接杀死精子，但精子的健康状况明显受到影响。精子的曲线速度（VCL，又称轨迹速度，是精子头部沿实际行走曲线的运动速度）受到的影响尤为显著，这代表在太空中，成功受精的机率可能大幅下降。此外，精子的活力与存活率的下降可能会随着微重力暴露时间的延长而加剧。不过，并非所有的影响都是负面的，微重力环境对于精子的 DNA 完整性、形态、氧化压力以及计划性细胞凋亡没有明显影响，这些结果为未来探索太空中的辅助生殖技术提供了一定的希望。

《柳叶刀》刊发的一篇论文称，2022 年全球罹患Ⅰ型或Ⅱ型糖尿病的成年人总数已超 8 亿，是 1990 年的 4 倍多。研究人员从各国收集了 1000 多项研究，涵盖 1.4 亿 18 岁以上人群的数据，利用统计工具，估算出了不同国家糖尿病的发病率和治疗情况。数据显示，从 1990 年到 2022 年，全球男性和女性的糖尿病发病率都翻了一番：男性从 6.8% 增至 14.3%；女性从 6.9% 增至 13.9%。由于人口增长和老龄化的影响，2022 年估计有 8.28 亿成年人患有糖尿病，比 1990 年增加了约 6.3 亿人。其中超过四分之一（2.12亿）糖尿病患者生活在印度，中国约 1.48 亿。绝大多数成年人罹患的是Ⅱ型糖尿病。肥胖和不良饮食是Ⅱ型糖尿病发病率上升，及其在各国之间造成差异的重要驱动因素。
