Researchers created HypoKG, an AI system that generates biomedical hypotheses grounded in real scientific evidence by combining three major biological databases (KEGG, Rhea, UniProt) into a unified knowledge graph. The system produced 13,200 hypotheses from six LLMs under four conditions, testing whether models truly reason from evidence or just produce convincing-sounding ideas.
Researchers introduced evidence-ledger adjudication, a workflow that pairs AI-generated claims with evidence packets, assigns support relations, and routes unsupported or contradicted claims back to the author for review. The system was tested on a 2,335-row blind benchmark built from AVeriTeC, CLIMATE-FEVER, and SciFact.
Researchers introduced Tree of Evidence (ToE), an AI system that builds argument trees to fact-check claims. It dynamically gathers and evaluates evidence from multiple sources to combat misinformation, including AI-generated content under Generative Engine Optimization (GEO) poisoning.
For the first time, prosecutors used ChatGPT logs as evidence in a criminal trial. This sets a precedent for how AI chat logs could be used in future legal cases. The trial ended in a mistrial, but the use of ChatGPT data is significant.
Researchers developed TCAR-Gen, an AI system that retrieves and combines evidence from historical criminal cases to answer complex questions. This advancement improves how AI handles temporal reasoning and evidence fusion, making it more reliable for detailed queries.
Researchers found that AI models often give inconsistent answers when presented with conflicting medical information. This highlights a key challenge in using AI for healthcare decisions. (~50 words)
