AI Insight
A study published in Nature found that approximately 90% of biomedical research papers published in December 2025 and archived in PubMed show evidence of assistance from artificial intelligence tools. This percentage represents a significant increase compared to earlier estimates of Large Language Model usage in scientific writing. The analysis focused specifically on papers indexed in PubMed, the primary database for biomedical and life sciences literature.
Why it matters
This finding reveals the rapidly accelerating integration of AI tools into scientific research workflows and academic writing. The widespread adoption raises important questions about research integrity, proper attribution of AI assistance, transparency in scientific publishing, and the need for updated guidelines on disclosure of AI use in scholarly work.
