Integrating local habitat structure and landscape heterogeneity is essential to conserve multitaxonomic biodiversity in European primary forests
Our results demonstrate that the drivers of primary forest biodiversity are largely context-dependent; therefore, conservation strategies based on single biodiversity indicators or individual structu...

If you can only complete the schoolwork with the chatbot, you haven’t learned anything. Your brain has atrophied. Nothing has happened in your head.
A recent study of 26,000 Chinese secondary-school students found that A.I. adoption led to an 18 percent increase in homework scores, but a 20 percent decline in scores on secure exams. The implication was that rushing through homework with help from chatbots degraded the deeper learning needed to perform well when the technology was not available.
