Dental AI scribes convert chairside dental speech into structured electronic medical records (EMRs). Public data for this task is scarce because dental visits include private speech, regional language, and noisy operatory audio. We introduce DentalVoice, a Chinese dental dialogue and speech dataset for AI scribe research. It contains 13,861 multi-turn dialogues, 162,612 turns, and approximately 274 hours of generated speech. Each case is grounded in a real dental EMR, guided by a dental knowledge graph, conditioned on patient profiles, and augmented with chairside acoustic conditions. We validate the generated dialogues using LLM judges and clinical experts, finding that clinical knowledge retrieval improves safety and professionalism, while persona constraints enhance interaction realism. Next, we benchmark dental automatic speech recognition (ASR) and Subjective-Objective-Assessment-Plan (SOAP) note extraction. Results reveal persistent errors in dialectal ASR, dental terminology recognition, treatment normalization, and distinguishing planned from completed procedures.

Large language models (LLMs) have shown remarkable capabilities in general domains, but their application to multi-omics biology remains underexplored. To address this gap, we introduce Biology-Instructions, the first large-scale instruction-tuning dataset for multi-omics biological sequences, including DNA, RNA, proteins, and multi-molecules. This dataset bridges LLMs and complex biological sequence-related tasks, enhancing their versatility and reasoning while maintaining conversational fluency. We also highlight significant limitations of current state-of-the-art LLMs on multi-omics tasks without specialized training. To overcome this, we propose ChatMultiOmics, a strong baseline with a novel three-stage training pipeline, demonstrating superior biological understanding through Biology-Instructions. Both resources are publicly available, paving the way for better integration of LLMs in multi-omics analysis.
