Across the Miocene-Pliocene boundary (MPB; 5.3 million years ago, Ma), late Miocene cooling gave way to the early-to-middle Pliocene Warm Period. This transition, across which atmospheric CO2 concentrations increased to levels similar to present, holds potential for deciphering regional climate responses in Asia-currently home to more than half of the world's population- to global climate change. Here we find that CO2-induced MPB warming both increased summer monsoon moisture transport over East Asia, and enhanced aridification over large parts of Central Asia by increasing evaporation, based on integration of our ~1-2-thousand-year (kyr) resolution summer monsoon records from the Chinese Loess Plateau aeolian red clay with existing terrestrial records, land-sea correlations, and climate model simulations. Our results offer palaeoclimate-based support for 'wet-gets-wetter and dry-gets-drier' projections of future regional hydroclimate responses to sustained anthropogenic forcing. Moreover, our high-resolution monsoon records reveal a dynamic response to eccentricity modulation of solar insolation, with predominant 405-kyr and ~100-kyr periodicities between 8.1 and 3.4 Ma.

Collaboration among scholars in scientific research is increasingly common, making it important to address how to recommend suitable collaborators, especially for their first cooperation. To address this issue, this study focuses on 1487 core scholars in the field of library and information science in China, and then analyzes the impact of academic differences between these scholars in their first collaboration by using the propensity matching score method. It uncovers potential driving factors for scholars to reach first collaborations, including similar research productivity, contrasting academic influence, aligned research directions, and distinct research focuses. Then, the distribution of features of three types of first cooperation demonstrates that if one or both partners publish the first paper in this collaboration, the collaborative relationship tends to be more enduring and stable. In addition, the subsequent collaboration of scholars and the change in their academic differences are related to the initial academic differences between the two parties in the first collaboration. These patterns can be used to improve the accuracy and effectiveness of the scholar recommendation mechanism, hence promoting research collaboration and knowledge exchange. [ABSTRACT FROM AUTHOR]
