A first-of-its-kind study reveals that when mice interact socially, specific brain cell types synchronize in "shared neural spaces," and AI agents develop analogous patterns when engaging in social behaviors.

Scientists at the National Institutes of Health (NIH) and their colleagues at the University of California, San Diego, have found that fine-particulate air pollution, which includes pollution from vehicles and industry, was strongly associated with increased genomic changes in lung cancer tumors among people who have never smoked. By assembling the largest-ever whole-genome analysis of lung cancer in individuals who have never smoked, researchers were able to link air pollution exposure to increased cancer-driving and cancer-promoting genetic mutations. This could potentially lead to more prevention strategies for never-smokers.
