A Minimally Invasive Framework Reveals Region‐Specific Cerebrovascular Remodeling in Aging Using Intravital Functional Ultrasound Imaging and Ultrasound Localization Microscopy (fUS‐ULM)

Advanced Science, EarlyView.
A high‐resolution intravital imaging platform combining functional ultrasound and localization microscopy enables longitudinal, minimally invasive assessment of cerebrovascular function in aging studies. The present investigation reveals aging‐related reductions in neurovascular coupling, arteriole‐to‐venule ratio and vascular density, introducing a ...

Fully Transparent Haptic Interface for High‐Resolution Tactile Feedback on Touchscreens

Advanced Science, EarlyView.
Integrating haptic feedback into touchscreens—enabling users to feel what they see on screen—has been a longstanding goal. In this article, B. Shan et al develop a transparent morphable haptic interface that transforms touchscreens into finely detailed, programmable morphable surfaces, enabling more effective and immersive human‐computer interaction ...
