▲ 摘要：晚新生代全球平均海平面（GMSL）的变化仍不确定。研究者利用对海水氧—18同位素变化的重建，重建了自450万年前以来的全球平均海平面情况。这一重建考虑了温度驱动的全球冰盖氧—18同位素的变化。在450万年至300万年前期间，海平面高位期仍比现在高出最多20 米，而首次低于现在的海平面低位期表明北半球冰川作用始于400万年前。

▲ 摘要：光谱学作为判定物质结构与化学成分的关键技术，已广泛应用于众多科学领域。传统光谱技术受限于窄缝或光栅结构，必须在光谱分辨率与光学透射率之间进行权衡，因而无法同时实现高灵敏度与高效率测量。研究者提出名为RAFAEL的亚埃级超高通量瞬时光谱技术，该技术基于铌酸锂集成可重构光子器件，成功突破了上述局限。
