Biological networks, as physical systems, comprise interconnected biomolecular or cellular components whose interactions give rise to emergent functional organization in living organisms. They include gene regulatory, protein–protein interaction, metabolic, neuronal, and signaling networks, each instantiated by tangible entities such as DNA, proteins, metabolites, or cells and their spatially constrained contacts. These systems exhibit nontrivial topology (e.g., modularity, hubs, motifs) and dynamic behavior governed by biochemical reaction kinetics, diffusion, and mechanical coupling. Biological networks underpin robustness, adaptability, and information processing in cells and tissues, and are quantitatively studied using tools from statistical physics, nonlinear dynamics, and network theory.

The development of humans and other animals unfolds gradually over time, with cells taking on specific roles and functions via a process called cell fate determination. The fate of individual cells, or in other words, what ...
For more than a century, scientists have wondered why physical structures like blood vessels, neurons, tree branches, and other biological networks look the way they do. The prevailing theory held that nature simply builds ...
