“Time Is Brain” – for Cell Therapies

Advanced Science, EarlyView.
The concept that “time is brain” extends to stem cell therapy for stroke. Evidence across preclinical and clinical studies indicates that delivery timing shapes graft survival, integration, and efficacy by matching the evolving post‐stroke microenvironment.

Photonic Time Crystals and Time‐Varying Electromagnetic Metamatter: A New Direction for Ultrafast Tunable Photonic and Microwave Materials and Devices

Advanced Science, EarlyView.
Photonic time crystals (PTCs) are systems in which electromagnetic parameters are modulated periodically in time, producing momentum bandgaps via temporal scattering rather than spatial Bragg processes. This review examines the theoretical frameworks, modeling, and computational tools for time‐varying media, and summarizes experimental demonstrations ...
