Researchers Incorporate Silicon into a Living Organism: is this the Building of a Bridge between Man and Machine?

Silicon is the second most common element in the Earth's crust, after oxygen. However, aside from its non-organic use by certain sea sponges and microorganisms, very little silicon is used by Earth's biology, despite making heavy use of other common elements, such as carbon, hydrogen, iron, magnesium and oxygen.
