    materials have a long history on planet Earth. New innovations in science and technology seek to purposefully mix living materials and nonliving materials, and create objects and substances that are both. In a recent study at MIT, scientists found E. coli to be useful in the production of a biofilm circuit board; moreover, hybrid materials will someday help humans in the areas of architecture, health, and electronics. Hybrid materials can be found in almost every part of nature, ranging from the bones
