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.

How might the discovery of semi-synthetic organisms change our approach to biotechnology?

How do the researchers ensure that semi-synthetic organisms do not survive outside controlled environments?

What implications does the creation of semi-synthetic life have for our understanding of life in the universe?

What are the fundamental laws of chemistry and physics that the researchers refer to in their work?
