MIT's Astra invents its own scientific instruments, finds metamaterial 2.1x stronger than reference

MIT professor Markus Buehler says Astra, a world-builder and explorer AI, can invent its own scientific instruments — a game-changing threshold. From just a few images of a biological microstructure, it spun up a full metamaterials lab and used its own creation to discover a design with 2.1x the reference work-to-failure/peak-strength ratio, a striking AI-for-Science demonstration.
