Proteins are the molecular machines that make all living things hum—they stop deadly infections, heal cells and capture energy from the sun. Yet because our basic understanding of how proteins work has until now remained a mystery, humans have only been able to harness the power of proteins by modifying ones we happen to find in nature. This is beginning to change. Enabled by decades of basic research, the rise of inexpensive computing, and the genomics revolution in reading and writing DNA, scientists can now design new proteins from scratch with specific functions.
