Protein engineering may be the future of science

Protein molecules formation

Scientists are increasingly betting their time and effort that the way to control the world is through protein. Proteins are what makes life animated. They take information encoded in DNA and turn it into intricate three-dimensional structures, many of which act as tiny machines.

Proteins work to ferry oxygen through the bloodstream, extract energy from food, fire neurons, and attack invaders. One can think of DNA as working in the service of proteins, carrying the information on how, when and in what quantities to make them.
