Lava lamp experiments provide insights into how cells could sel-organize. These experiments involve the formation of vesicles in a liquid-liquid phase separation system, resembling how biological cells form membrane-bound compartments. The vesicles in the lava lamp experiments exhibit dynamic behaviors such as budding, fusion, and coarsening, which mimic cellular processes like membrane trafficking, cell division, and growth. These observations suggest that physical mechanisms driving self-organization in simple synthetic systems may be analogous to those underlying biological cellular organization, offering clues to understanding the fundamental principles of cellular compartmentalization and the origins of life.
