Complex network theory has become a key analytical framework in modern physics for studying structure, dynamics, and emergent behaviour in complex systems.

An experimental technique that started life in nuclear and particle physics is now being used to measure chemical reactions inside the human body and to help diagnose cancer and heart disease in ...

Nonlinear optical materials such as silicon can be used to make on-chip devices that break dynamic reciprocity. (Courtesy: K Xia) A new method for making devices that act like a “one-way street” for ...
