LOOP

A new free course breaks down how Claude Code, Anthropic's AI coding agent, works internally and teaches harness engineering — the practice of building the scaffolding and feedback loops around AI models. The material is aimed at machine learning engineers wanting to understand and replicate agentic coding systems.

Researchers have proposed a new loop design for quantum sensors that could make magnetic field measurements more precise. The advance is aimed at applications in medicine, such as imaging and diagnostics, as well as communications technology. Coverage so far is limited to science outlets describing the design's potential to improve sensitivity in detecting weak magnetic signals.
