Advanced Science, EarlyView.Ilizarov bone transport accelerates healing of soft‐tissue wounds through unclear mechanisms. In a rat model, sustained mechanical distraction elicits calcitonin gene‐related peptide (CGRP)‐dominant sensory reinnervation, creating a niche that shifts immune cells from inflammatory to repair‐promoting states and speeds re‐epithelialization.

Snapshot Spatiotemporal‐Spectral Imaging Enabled by Joint Photonic Encoding
Advanced Science, EarlyView.Spectra4D enables snapshot spatiotemporal‐spectral imaging by combining high‐speed DMD temporal modulation with CMOS‐integrated Fabry‐Pérot spectral encoding. From a single 2D measurement, a dual‐mask‐guided reconstruction network recovers multiple time‐resolved hyperspectral frames, enabling high‐fidelity observation of rapidly evolving spatial ...

Pyrolyzed Photoresist as a Continuous‐Tone Mask for Grayscale Lithography
Advanced Science, EarlyView.True grayscale contact photolithography masks are created by pyrolysis of 3D multiphoton resist patterns. The resulting carbon masks retain micrometer‐scale patterned features while providing continuous‐tone optical transmission. This approach provides access to high‐quality grayscale lithography without requiring exotic materials or commercial mask ...
