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 brain's ability to process information is known to be supported by intricate connections between different neuron populations. A key objective of neuroscience research has been to delineate the processes via which these ...
"As complex living systems, we likely have trillions upon trillions of tiny nanoscopic holes in our cells that facilitate and regulate the crucial processes that keep us alive and make up who are," says Marija Drndić, a physicist ...
