The paper proposes a new method for measuring the novelty of biomedical research by calculating latent distances between knowledge units—specifically MeSH terms—using three types of relationships: network, semantic, and hierarchical. It demonstrates that each relationship captures distinct distances and that combining all three yields a more accurate novelty assessment than existing metrics. Validation on a large PLoS ONE dataset and a H1 Connect dataset shows stronger alignment with peer judgments compared to prior indicators.

Large language models (LLMs) are widely used to assist writing, but this study shows they alter both tone and meaning of human text. A user study found that heavy LLM use increased neutral essays by nearly 70% and made writers feel less creative and less in their voice. Even when prompted to make only grammar edits, LLMs changed the semantic content of essays and produced AI-generated scientific reviews that were less focused on clarity and significance and scored higher on average.
