▲ Abstract：
Many exoplanets have 科学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：
Increasing fertilization has pushed the nitrogen cycle beyond planetary boundaries,文导闻科 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：
Previous brain-wide association studies (BWAS) have linked specific environmental and behavioral variables to brain variability. In this work, we mapped 649 variables to children’s brains and compared the resultant BWAS maps with each other and with neurobiological reference patterns. Socioeconomic status (SES) showed the strongest brain-wide associations. The SES associations were strongest in motor and sensory but not cognitive regions, a pattern shared across many BWAS maps, including intelligence quotient (IQ). A single, common BWAS brain pattern existed across variables that was most reflective of a child’s socioeconomics. Adjusting for SES weakened brain-IQ associations, eliminating the BWAS motor and sensory pattern. Brain-with-IQ associations also did not generalize when trained on higher-SES subsamples. Thus, children’s brains vary the most with SES, potentially through SES-dependent sleep deprivation and stress.

▲ 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.

▲ Abstract：
Plants can move rapidly without muscles, as seen in the Venus flytrap’s snapping lobes—a long-standing puzzle in plant biomechanics. Trap closure involves an elastic instability, but the active mechanical driver has remained elusive. Using in situ hydraulic and mechanical measurements, we identified the motor driving this transition. Closure occurs too quickly to be explained by water transport, revealing a distinct, nonhydraulic mechanism: a rapid (about one second) softening of the epidermal cell wall, releasing elastic energy stored in the trap. This represents the fastest modulation of wall mechanics reported in plants. Our finding reveals a mode of plant motility based on dynamic tuning of material properties, suggesting principles for muscle-free, bioinspired actuation.

▲ Abstract：
Spontaneous emission is inherently associated with spectral broadening mechanisms, resulting in finite bandwidth in the emitted light. Narrowing this linewidth toward the monochromatic limit has long been a central pursuit in photonics, as it determines the ultimate color purity of nonstimulated light sources. Organic luminescent materials offer facile wavelength tunability but typically exhibit broad emission bands (>40 nanometers). The emergence of multiple-resonance emitters has provided a promising route to overcome this limitation, yet most reported systems remain within 20 to 30 nanometers. We present a molecular design strategy that amplifies the multiple-resonance effect through molecular repetition, yielding fluorescence with linewidths of 6.9 nanometers in toluene, 5.5 nanometers in 3-methylpentane, and 9.1 nanometers in a doped polymer film, placing this molecular framework among the narrowest-band organic luminophores reported.
