Researchers mapped 190,000 miles of ancient Roman roads, revealing that the network’s true hub was Constantinople, not Rome, and that routes were often curved by terrain rather than strictly straight.
In 2025, mathematicians Richard Montgomery, Natalie Behague, and Daniel Iľkovič proved the long-standing 'sandwich conjecture' in graph theory. This breakthrough allows researchers to derive properties of complex random regular graphs by analyzing simpler random binomial graphs, effectively creating a mathematical 'sandwich' where the regular graph is bounded between two binomial graphs. The proof, published in 2026, resolves a hypothesis posed in 2004 by Jeong Han Kim and Van Ha Vu, offering a new method to understand complex networks without proving each property from scratch.
A new study analyzing 300,000 km of Roman roads reveals that the network was more distributed than previously thought, with provincial capitals serving as key hubs rather than Rome. The research also shows that Roman roads were straighter only where terrain allowed, and their continuity into the modern era is less direct than assumed.
A PsyPost report on a study of 802 Italian adults shows that accumulating adverse childhood experiences are associated with more severe and tightly interwoven substance and behavioral addictions in adulthood. Tobacco use, overeating, and compulsive sexual behavior emerge as central hubs in this interconnected network, highlighting the need for trauma-informed prevention and integrated treatment, though the cross-sectional design and recruitment bias limit causal conclusions.
A study using network modeling found that cognitive traits like processing speed and flexibility influence depression indirectly through emotion regulation strategies, especially rumination, highlighting the complex interplay between cognition and emotional regulation in depression development.
A study from the University of Jyväskylä reveals that a tighter interconnection between different domains of functional capacity in the elderly may indicate reduced system resilience, leading to cascading failures. The research, which utilized network analysis, suggests that maintaining a balance between interconnectedness and independence within these domains is crucial for preserving functional capacity and overall well-being in old age. The study, part of the AGNES project, emphasizes the importance of maintaining reserve capacity and compensatory mechanisms to adapt to aging-related challenges and preserve quality of life.
