Abstract: Scientists are currently exploring the structure and behavior of complex biological systems, which consist of networks of interacting entities. A recent paper in Proceedings of the Royal Society of London Series B Biological Sciences describes the distinctive characteristics of aging-related proteins in the yeast protein-protein interaction network. In this Perspective, I discuss the implications of these findings for longevity research.
