Breakthrough in Understanding the Origins of Earth's First Cell Membranes
Researchers at the University of California San Diego have discovered a potential mechanism for the formation of early Earth protocells, which could explain the origins of life. The study, published in Nature Chemistry, reveals that simple molecules like cysteine and short-chain choline thioesters can spontaneously form lipid membranes when catalyzed by silica glass. This process, which does not require enzymes, could have led to the creation of protocell-like structures capable of sustaining biochemical reactions, offering insights into how life might have emerged from non-living matter.
