Microlightning: A New Spark in the Origin of Life Debate

New research published in Science Advances suggests that microlightning within water droplets may have played a crucial role in the formation of Earth's earliest organic molecules. Building on the famous Miller-Urey experiment, scientists found that electrical discharges between oppositely charged water droplets can produce amino acids, the fundamental building blocks of life. This process, potentially more frequent than lightning on early Earth, could have provided an abundant source of life's precursors. This challenges existing theories suggesting life originated from hydrothermal vents or arrived via asteroids, offering a compelling new perspective on the origin of life.
