Staggering 90% of biomedical papers now show signs of AI help

A study analyzing biomedical papers published in December 2025 found that nearly 90% showed signs of AI-assisted writing, significantly higher than previous estimates. The research, posted on arXiv and based on analysis of word frequencies common in AI-generated texts, suggests that AI use in scientific writing is increasing. The study found higher AI detection rates in abstracts, introductions, and discussions compared to methods and results sections. Researchers note that while the methodology may overestimate AI use, the trend indicates growing reliance on AI tools. Some experts caution that the findings may not represent all scientific fields and more research is needed.

A new study suggests that nearly 90% of biomedical research papers published in December 2025 show signs of having been assisted by artificial intelligence. The research, posted on the arXiv preprint server on 12 August 1, indicates that 77% of papers in the PubMed Central database from 2025 and 52% from 2024 were influenced by large language models (LLMs). These numbers far exceed earlier estimates, such as a 2025 study that found at least 13.5% of 2024 papers had AI influence based on abstracts alone. The study's lead author, Dmitry Kobak, a computer scientist at Ghent University, initially doubted the findings. However, after additional verification, he confirmed the accuracy of the data. The methodology used in this study is more sensitive to detecting AI use, resulting in higher estimates compared to prior studies. Researchers suggest that these high figures align with a 2025 survey indicating that 71% of scientists use AI for writing help. They believe the actual number may be even higher due to underreporting in surveys. Some experts caution that while the findings highlight the growing role of AI in science, they may not represent all areas of research. Still, the trend shows that AI integration into scientific publishing is becoming permanent. AI appears to be more frequently used in abstracts, introductions, and discussion sections than in methods and results. Kobak warns that using AI in results sections can lead to fabricated data, while its use in introductions might introduce biases into the scientific narrative.

Bias read (Center): The article presents factual findings about AI use in scientific publishing without overt ideological framing. While it discusses concerns about AI influence in research, it does not take a clear partisan stance. The tone remains objective, focusing on the study's methodology, findings, and expert反应

Why factuality (85): The article reports on a preprint study from arXiv that estimates high rates of AI assistance in biomedical papers, citing specific percentages for different years. It references other studies from 2025 and 2026 to provide context and comparison. While the study has not been peer-reviewed, the artic

Why objectivity (80): The article remains largely neutral, presenting the study's findings and expert reactions without overt bias. However, it emphasizes the 'staggering' nature of the statistic and quotes a researcher who was initially skeptical, which may subtly frame the issue as significant. The tone is informative

Fears of AI-induced armageddon are overdone

The Economist article argues that fears of artificial intelligence leading to catastrophic outcomes, such as global conflict or societal collapse, are exaggerated. The piece suggests that while AI presents challenges, these risks are often overstated by critics who fail to consider the technology's potential benefits and the existing safeguards in place. It emphasizes the importance of balanced discourse around AI development and regulation, rather than alarmist narratives.

Bias read (Center): The article presents a balanced view of AI-related concerns, acknowledging both the risks and the potential for overreaction. While it leans slightly toward downplaying existential threats, it does not take a clear ideological stance and avoids promoting any specific political agenda. The framing is

Why factuality (70): The article argues that fears of AI-induced catastrophe are exaggerated, citing expert opinions and historical precedents. While it doesn't provide a primary source, it aligns with broader academic and industry discussions that caution against hyperbolic narratives around AI risks. This supports a c

Why objectivity (80): The article maintains a balanced tone, acknowledging valid concerns while challenging overly alarmist views. It presents arguments from both sides without taking an overtly ideological stance, though it leans slightly toward a more optimistic interpretation of AI's trajectory.
