A living organism relies on the interactions of molecular constituents within itself and with its surroundings to function properly. However, it is clear that the full functionality of a living organism cannot be determined solely by its molecular makeup and interactions. Recent studies have shown that the dynamic spatial organization of different molecular components within a cell, different cells within a tissue, and different organisms within a community, play critical roles in enabling the full functionality of the organism. Furthermore, differential spatial organizations may imply a new level of functional regulation that complements the classic mechanism by molecular interactions. Understanding why and how biological functions are spatially organized requires a concerted effort from scientists of diverse backgrounds, as the spatial organization operates from the nanometer-scale of small liquid droplets condensates inside cells to centimeter-scale skin color pattern formation in a...
