Earliest siphuncle-bearing cephalopod from the early Cambrian

Nature, Published online: 29 July 2026; doi:10.1038/s41586-026-10868-y

Early Cambrian Eoceras shaanxiense gen. et sp. nov. preserves septa and a segmented tube resembling a primordial siphuncle, extending cephalopod origins and revealing early assembly of chambered shells used for buoyancy regulation.

Quasi-ballistic ion transport in a vertical microrod enabling efficient evaporation-driven power generation

Nature Energy, Published online: 27 July 2026; doi:10.1038/s41560-026-02117-3

Evaporation-driven power generators are often limited by non-directional fluid flow, which reduces their efficiency. Guided by machine learning, Wu et al. developed a vertical microrod generator that improves ion transport, increasing efficiency and power density.
