New Artificial Bone Made of Wood

Italians scientists have developed a new artificial bone made from wood should be an improvement over the plastic and metal that are now used for implants. Derived from organic material, the new bone substitute will promote faster healing.
To create the bone substitute, the scientists start with a block of wood -- red oak, rattan and sipo work best -- and heat it until all that remains is pure carbon, which is basically charcoal.

The scientists then spray calcium over the carbon, creating calcium carbide. Additional chemical and physical steps convert the calcium carbide into carbonated hydroxyapatite, which can then be implanted and serves as the artificial bone.
