A graduate student has created the first man-made biological leaf. It absorbs water and carbon dioxide to produce oxygen just like a plant. He did this by suspending chloroplasts in a mixture made out of silk protein. He believed it can be used for many things but the most striking one is the thought that it could be used for long distance space travel. Plants do not grow in space, but this synthetic material can be used to produce oxygen in a hostile environment. (Video)
