AlphaFold is an AI system created by DeepMind that can predict the 3D structure of proteins with high accuracy by analyzing their amino acid sequences. It achieved this by training on a vast database of known protein structures and developing an understanding of the physical principles that determine how proteins fold. In a recent competition, AlphaFold dramatically outperformed other state-of-the-art methods and will help accelerate scientific research in areas such as disease research and sustainable energy.
