Icy cycles may have driven early protocell evolution
Tokyo, Japan (SPX) Jan 26, 2026
Modern cells rely on intricate molecular machinery and genetic programs to grow and divide, but the earliest protocells were likely simple lipid-bound compartments whose behavior depended mainly on their physical and chemical properties. A new experimental study suggests that subtle differences in membrane composition could have helped these primitive compartments grow, fuse, and hold on to gene
