Pirates can now trade in their peg-legs for real legs as scientists transform wood into bone.In a Royal Society of Chemistry journal Italian chemists show that ordinary wood can be turned into bone suitable for repairing damaged limbs.It brings a whole new meaning to the term "tree surgery".The microstructure of the wood is the perfect natural template for making bone as it allows growth of blood vessels and tissues, Anna Tampieri and colleagues report in the Journal of Materials Chemistry.By treating wood with a fairly simple set of chemical processes, the natural structure of the wood is retained.The wood is...

Scientists have cultured small pieces of heart tissue which beat in the same way as the whole organ.The Massachusetts Institute of Technology team hope the work will lead to new ways of repairing heart damage. They grew the tissue from a few rat heart cells which were placed on an artificial scaffold, and then stimulated with an electric current. Researchers told Proceedings of the National Academy of Sciences: "Think of it as a patch for a broken heart." Myocardium, or heart muscle cells, cannot regenerate after injury, limiting the effectiveness of standard therapies. And heart cells are difficult to culture...
