Summary: Scientists are developing transparent wood as a sustainable alternative to transparent plastic, with potential applications in smartphone screens, insulated windows, and more. The material is created by modifying or removing lignin, the glue that holds wood cells together, and filling air pockets with epoxy resin. Transparent wood is stronger than plastic and glass, making it a promising option for various products and architectural features.
