Google has open-sourced its AI hydrology framework powering Flood Hub, enabling agencies to train localized flood models using LSTM architecture and the Caravan dataset. The upgraded model extends reliable forecast horizons by six days in gauged basins, supports PyTorch-based fine-tuning, and empowers meteorological services to build high-accuracy early warning systems while retaining full data sovereignty.

Google Research introduces PHRM, a system using smartphone front cameras during unlock events for passive heart rate monitoring with <10% MAPE across all skin tones and <5 bpm daily RHR error, releasing an open dataset and model.

The optimal organization of AI agent systems depends on task complexity and model type; Google's research with 150+ experiments shows centralized/hybrid structures work best for OpenAI models, while Google models excel in decentralized coordination.

ERA, a tool developed by Google using Gemini, assists scientists in writing and optimizing scientific code, significantly speeding up the process of scientific discovery. It has been tested across various disciplines and has shown expert-level performance. ERA is now being made accessible to scientists worldwide through Gemini for Science, and has been used in several projects, including epidemiological forecasting, environmental modeling, and atmospheric CO2 mapping.

Qdrant 1.18 is released, introducing TurboQuant, a new quantization method developed by Google Research, offering higher memory efficiency and better recall.
