Spot Bitcoin ETFs recorded USD 191 million in daily net inflows, led by BlackRock’s IBIT with USD 163 million.

Researchers at China’s University of Science and Technology have shown that their handheld quantum magnetometer can detect a subway train moving under a city street. In real-world tests, the small device tracked changes in Earth’s magnetic field as the train arrived, stopped, and left the station.Peng Xinhua and his team developed the magnetometer for places…

There’s a category error that shows up in many LLM systems: We retrieve a few documents, put them in context, generate a fluent answer with links, and then we call the answer “grounded.”
