This wool glows under ultraviolet light thanks to a natural dye. At the Autonomous University of Coahuila, in Saltillo, Mexico, undergrad Fabiola Ramírez Arismendez and the professor she works with, Catalina M. Perez Berumen, are looking for dyes derived from resources native to northern Mexico. This dye was extracted from the kidneywood tree, or palo azul, whose wood is rich in flavonoids that spontaneously oxidize in air and can fluoresce eerie colors. The project is a collaboration with La Favorita Sarape School, a technical school in Saltillo dedicated to handcrafts that aims to preserve the local tradition of making woven shawls or blankets known as sarapes.
