In a groundbreaking discovery, scientists from Rice University have found a type of bacteria that can survive by releasing electricity instead of relying on oxygen. These microorganisms use a natural process to transfer electrons outside their cells, enabling them to generate energy in oxygen-free environments such as deep-sea vents or the human gut. The finding uncovers a previously hidden survival mechanism in nature and holds significant promise for clean energy, biotechnology, and environmental monitoring. The study offers new insight into how ancient life forms adapted to extreme conditions and how we might use them for future technologies.
