Wiley May 21 2026 Like fireflies and many deep-sea creatures, certain fungi can naturally emit light through bioluminescence pathways in which specialized enzymes convert chemical energy into visible light. Medical researchers have used fungal light-producing enzymes in the Fungal Bioluminescence Pathway (FBP) to visually track processes like tumor progression and inflammatory responses. New research published in The FEBS Journal provides insights that may help improve and expand such
