What to know about AI-driven scientific discovery

Researchers at North Carolina State University have developed PoLARIS, an autonomous AI-powered laboratory that identifies lead-free light-emitting nanomaterials. The system uses a closed-loop process of synthesis and analysis to optimize material recipes significantly faster than traditional human-led methods.
