What Happened

DeepMind's AlphaFold 2 solved the 50-year-old protein structure prediction problem, achieving accuracy comparable to experimental methods at CASP14. It could predict how proteins fold from their amino acid sequences — a problem that had stumped biologists for half a century.

Why It Mattered

Perhaps the most scientifically significant AI achievement ever. AlphaFold has since predicted structures for nearly all known proteins (200M+). Revolutionized drug discovery, biology, and medicine. Led to the 2024 Nobel Prize in Chemistry.
