Scientists have developed a process that allows them to manipulate wood to make it denser and harder than the natural product. They used the resulting material to make items like wooden knives and nails that rival traditional steel. There is also the possibility that wood processed in this way could replace existing products that are known to be harmful to the environment. "Trees are renewable and wood is sustainable," Li said. "If we look back to mother nature, we can use this natural material toward a sustainable future."
