TED: The radical possibilities of man-made DNA | Floyd E. Romesberg

The video explores the creation of a six-letter genetic alphabet, expanding the natural four-letter DNA with two synthetic letters, x and y. This innovation allows for the development of semi-synthetic organisms capable of producing new proteins with potential applications in medicine and biotechnology. The research challenges the notion of life's perfection and suggests that life could exist in various forms. Safety measures ensure these organisms cannot survive outside controlled environments. The work opens possibilities for new life forms and expands our understanding of life's potential in the universe.
