AI Scientific Discovery 2025: From Weather Prediction to Materials Design

Google DeepMind's GNNCast now provides 10-day weather forecasts at 0.1-degree resolution, outperforming traditional numerical weather prediction models at 1/1000th the compute cost. Simultaneously, Microsoft Research's MatterGen generates novel crystal structures for battery materials on demand. The common thread: AI is replacing computational simulation in scientific workflows — not supplementing them. Researchers at MIT report AI-assisted materials discovery identifying candidates 100x faster than lab screening.
