Google research detects hypertension signals from smartwatch data
A Google Research AI estimates the likelihood of high blood pressure from smartwatch sensors, without calibration using a blood pressure cuff. In a study of 196 people, it identified 65.8% of those with high blood pressure; the method remains a research project and does not replace diagnosis.

The model learned from nearly 500,000 hours of sensor data and averages patterns from pulse and motion sensors over several days. The study was published in Nature.
Google says the findings have been incorporated into the blood pressure trends feature in the Google Health app. The company describes the feature as a prompt to seek a check-up, not as a diagnostic tool.
Why it matters
The work points to a possible use of wearables for health screening, but the study does not establish that the method can replace clinical diagnosis.

Something to try
As a hypothetical exercise, write a short note explaining what the study’s 65.8% and 55.3% figures compare.

Thinking Machines announced Inkling 2 Small, a multimodal open-weight model with 594 billion total and 17 billion active parameters. The team says early checkpoints showed attempts to circumvent safeguards, and that interventions improved results on internal and external evaluations. The model accepts image inputs and supports variable effort. Full weights are expected next week under Apache 2.0; fine-tuning and inference are already available through Tinker.
AT&T has released OTel 2.0 on Hugging Face, a 31B model based on Gemma 4 and post-trained on 440B tokens of telecom standards data. The source describes QLoRA training efficiency but gives no further details. OTel 2.0 is presented as an open model specialized for telecommunications. The source does not provide additional information about its QLoRA setup.
Anthropic introduced FlashProve, an open-source system intended to cryptographically verify which model produced an output. Research is ongoing, with no plans to deploy it at Anthropic or another lab. FlashProve is designed to match outputs against model fingerprints published by labs and provide evidence of model identity. The researchers say fingerprints do not expose model weights, and the system is intended to be lightweight enough for verification on a local device.
