Google Research proposes a cuffless, calibration-free AI system for smartwatch hypertension detection
Google Research published in Nature the AI-PPG-ACC-HTN multimodal AI system, which can passively detect signs of hypertension using only the PPG and accelerometer signals of consumer-grade smartwatches, without cuff calibration. The system first performs self-supervised pretraining on unlabeled sensor data totaling 492,347 hours from 2,109 participants, then aggregates multi-day waveform embeddings into person-level features and, combined with height, uses logistic regression to output the probability of hypertension. In a prospective study of 196 participants across 5 U.S. sites, in the initial screening setting the sensitivity was 65.8%, specificity 90.0%, and PPV 80.6%; in the confirmation setting among 48 people with elevated office blood pressure, the sensitivity was 78.4%, specificity 90.9%, and PPV 96.7%. The research team states that this work is an early feasibility exploration, does not replace cuff-based diagnosis, and does not point to any existing or forthcoming commercial feature.

Google Releases EmbeddingGemma 2 Paper
Google has released the EmbeddingGemma 2 paper, introducing an Apache 2.0-licensed on-device multimodal embedding model that maps text, code, images, audio, and video into the same vector space. Built on Gemma 4, the model learns from the larger Gemini Embedding 2 and is tuned with contrastive training; with 744M parameters, it outperforms models 2 to 12 times larger on multiple tasks. On the Pixel 11 Pro, the quantized text weights occupy about 191MB of active memory, while the full multimodal model takes about 567MB; the context window is expanded 4 times to 8K tokens, accommodating about 5.5 minutes of audio, 29 images, or 58 video frames. Embedding speech directly scores 69.54 on the MSEB spoken query retrieval benchmark, higher than the 57.59 achieved by transcribing first and then retrieving, and code retrieval on MTEB Code improves from 68.76 in EmbeddingGemma 1 to 78.68.

Lin Dahua proposes that AI progress depends on smarter construction rather than mere scaling
On October 29, 2026, Lin Dahua, co-founder and chief scientist of SenseTime, proposed at CITIC Securities' 33rd Investor Forum that the key to AI progress is not just scaling up models, but rather smarter ways of building them. He emphasized that the "intelligence density" of data determines learning outcomes, and SenseTime has therefore developed a native multimodal model that integrates multimodal capabilities into the architecture and training from the very beginning. Lin Dahua also predicted that embodied intelligence will accelerate over the next one to two years, and SenseTime is also continuously exploring world models.
