Psychological stress during pregnancy is known to affect birth outcomes, but isolating its effects has been difficult. Researchers found that babies born in Japan immediately after the Fukushima nuclear accident were more likely to be born preterm or with low birth weights. Radiation exposure-related maternal anxieties significantly contributed to the differences in birth outcomes. The findings underscore the importance of clear communication and psychological support for pregnant women during crises to help prevent intergenerational harm.

This study employs advanced Large Language Models (LLMs) and Dynamic Topic Modeling to quantitatively analyze nearly 290,000 hydrology-related publications from 2000 to 2023. By intelligently parsing hundreds of thousands of global hydrology publications, the research overcomes the limitations of traditional bibliometric methods. It maps the field's trajectory, revealing a crucial thematic shift from traditional water resource management to eco-hydrology. The findings highlight the surging focus on climate change, the widespread use of the hydrological models, and the intense scientific attention on the Yangtze and Yellow River basins. This study provides a comprehensive overview of how the discipline has evolved to meet complex environmental challenges.
