Google builds a tool to pick candidate biomarkers out of wearable sensor data

A Google Research post dated 21 August 2026 describes a tool that prioritises candidate biomarkers from continuous wearable-sensor recordings, narrowing the field of signals worth investigating rather than leaving researchers to sift the whole stream.

What it means Wearables produce far more signal than anyone can chase, so the useful product is the shortlist rather than the stream.
