A wax worm, moth larva that eats wax made by bees to build honeycombs, is seen in a laboratory at the Spanish National Research Council (CSIC) in Madrid, Spain in this undated handout photograph obtained by Reuters on October 4, 2022. New research shows that two enzymes in the saliva of these worms readily break down polyethylene, the world's most widely used plastic and a major contributor to global plastic waste.
