▲ Abstract：

Increasing fertilization has pushed the nitrogen cycle beyond planetary boundaries, yet its fate remains uncertain owing to long-standing neglect of landscape water velocities in nitrogen models. Leveraging isotope-aided modeling across 3821 European catchments, we demonstrate that evolution of nitrogen cycling is strongly linked to shifts in landscape water velocities since 1980. We propose the concept of “wetness boundaries,” where hydrological transitions beyond boundaries amplify nitrogen accumulation and leaching, whereas conditions remaining within boundaries mitigate these processes. Applying this framework, we project reduced nitrogen leaching across 76% of Europe under mild hydrological shifts by 2100 but increasing nitrogen accumulation under pronounced deceleration of water cycling in Eastern and Southern Europe. These findings underscore emerging water quality risks under climate change and the need to mitigate extreme hydrological shifts.

▲ Abstract：

Many exoplanets have been observed with radius sizes between that of Earth and that of Neptune and are thus classified into two groups: super-earths (SEs) and mini-neptunes (MNs). There are no SEs or MNs in the Solar System, and the mechanisms responsible for their formation and evolution are debated. We investigated the relationships between the orbital period and eccentricity of SEs and MNs using both ensemble statistical analyses and individual measurements. We found that MNs follow an anticorrelation between orbital period and eccentricity, but SEs follow a different relation, possibly in the opposite direction. These trends imply that MNs and SEs are dynamically distinct populations. We suggest that SEs have been more strongly influenced by violent processes such as gravitational scattering and giant impacts, whereas MNs predominantly experienced quiescent secular evolution.

▲ Abstract：

The transformation of the Roman world [fourth to ninth centuries common era (CE)], culminating in the Western Roman Empire’s fall, marked a fundamental transition in European history. Key questions persist regarding the regionally specific nature of this transformation. We generated a paleogenomic dataset to reconstruct post-Roman organizations in the Little Hungarian Plain at microregional resolution. Genetic and archaeological analyses of two Roman (n = 68) and five post-Roman (n = 246) sites reveal a rise in Northern European ancestry, reflecting large-scale population movements into this region. Moreover, despite post-Roman sites sharing similar genetic profiles, material culture, and burial practices, they show distinct social structures, especially regarding the role played by biological relatedness. These findings highlight local hierarchies and reveal the making of a post-Roman polity.
