New research led by the University of Colorado Denver finds that Denver-area bus riders change their commuting patterns when faced with cold or rain, but not as much for wildfire smoke or ozone warnings. But weather alone doesn't tell the whole story. Whether riders had to pay a fare, what time of day they traveled, and whether or not the bus stop is protected against the elements also play a role. 

Boston University sociologist Sarah Miller discusses her new book on teen bullying, social media, and why schools need to rethink anti-bullying efforts.

A new paper published in the Proceedings of the National Academy of Sciences (PNAS), “Personality Pairing Improves Human-AI Collaboration” presents the first-ever, large-scale, randomized controlled experiment testing how AI agents  prompted to exhibit varying levels of the Big Five personality traits interacted with human personalities to shape human–AI collaboration and performance and what personality pairings proved to be the most effective. Co-authors are Sinan Aral, MIT Sloan School of Management professor and director of the MIT Initiative on the Digital Economy, and Harang Ju, an assistant professor at the Johns Hopkins University Carey Business School. Their results demonstrate that personality pairing can improve human–AI collaboration and performance. They also motivate future research on the complex implications of AI personalization for human–AI collaboration, teamwork, and performance.

Urban heat adaptation will gain in importance as climate change progresses. Researchers at the Karlsruhe Institute of Technology (KIT) have analyzed how sociodemographic factors (nationality, age, and rent) correlate with heat exposure throughout Germany. The clearest correlation involves nationality: In 84.2% of the analyzed cities, the air was significantly warmer at night in areas with a higher share of residents without German citizenship. The data show clear spatial differences in intra-city  temperature , but allow no conclusions to be drawn about their causes. The results have been published in Environmental Research Letters. (DOI: 10.1088/1748-9326/ae929e)
