Wind energy expansion is crucial for decarbonization but faces community resistance due to health concerns about turbine noise and infrasound. We combine US wind turbine data (2011–2023) with ...
Small water bodies (SWBs) are critical but often overlooked components of the global carbon cycle. We demonstrate that human activities, particularly agricultural nutrient loading and urbanization, ...
It’s increasingly hard to find peer reviewers. To address the problem, we propose a universal peer-review system based on the exchange of credits. Image credit: Dave Cutler (artist). Several factors ...
Insects were the first organisms to evolve flight and have since become the most abundant species on Earth. However, the lack of well-defined flight traits and predictive theory has made it difficult ...
The large size of the baby boom cohort depressed economic opportunities for that generation as it flooded the labor force in the 1970s. Contrary to the predictions of Richard Easterlin’s relative ...
The ordered arrangement of mechanosensory hair cells in vertebrate auditory epithelia relies on mechanical interactions among multiple cell types. Yet, how local mechanical heterogeneity produces ...
Figures were generated with Biorender.com. We thank Drs. A. Inoue and D. Ma for sharing the cells, E.Q. Chen for generating the 3D movie, and Dr. R. Irannejad for constructive comments and suggestions ...
While generative AI has been shown to enhance productivity, its influence on learning new skills remains unclear. Our research examines the impact of generative AI, specifically GPT-4, on student ...
