Did Life Begin in the Cold? New Experiments Point to an Icy Origin

Experiments reveal that unsaturated lipid membranes promote vesicle fusion and DNA retention during freeze–thaw cycles, highlighting icy environments as potential drivers of protocell evolution. Today’s cells are extraordinarily intricate. They contain internal scaffolding known as cytoskeletons, carefully controlled chemical reactions inside and outside the cell, and genetic material that governs nearly all aspects of their [...]
