Scientists have discovered a new species of glowing fungus gnat in Brazil’s Atlantic Forest – the first of its kind found in South America. This small fly can produce blue light from special organs in its body, similar to fireflies but using different chemical mechanisms. The discovery highlights how much biodiversity remains unknown in tropical forests. Impacts on everyday life: – Demonstrates the importance of preserving natural areas that may harbor undiscovered species – Provides new insights into how organisms produce biological light, which could inspire new technologies – Helps us better understand the evolution of bioluminescence across different species – Could lead to development of new research tools based on biological light production – Emphasizes the need for conservation of threatened ecosystems like the Atlantic Forest
