Identifying the chemical makeup of pigments used in ancient documents, paintings, and watercolors is critical to restoring and conserving the precious artworks. However, despite numerous efforts, scientists had been unable to determine the source of folium, a popular blue dye used to color manuscripts in Europe during the middle ages — from the 5th to the 15th century.

Experts estimate that of the 359 million tons of plastics produced annually worldwide, about 150–200 million tons end up in landfills or the environment. To make matters worse, the material derived from the small percentage of plastic that is recycled is of lower quality and can only be used a few times for items like clothing or carpets before it has to be discarded....
