Mitochondrial Quality Control in Degenerative Musculoskeletal Diseases: Signaling Networks and Therapeutic Landscapes

open access: yesAdvanced Science, EarlyView.
Mitochondrial quality control (MQC) collapse redefines osteoarthritis, intervertebral disc degeneration, and osteoporosis as disorders of organelle dysfunction. Damaged mitochondria leak mtDNA and metabolites, driving cGAS‐STING inflammation, epigenetic reprogramming, and metabolic memory.

Deciphering Electrochemical Generation, Transport, and Reactivity of Hydrogen Species in the Electrochemical Palladium Membrane Reactor

open access: yesAdvanced Science, EarlyView.
This study elucidates hydrogen transport and reaction mechanisms in ePMR using 1‐hexyne hydrogenation as a model reaction. Hydrogen transport operates via dual pathways involving hydrogen atom permeation and H2‐mediated re‐dissociation on secondary metal layers.

Spatiotemporally Precise Rheumatoid Arthritis Therapy via a Triple‐Locked Cascaded Nanoplatform With Dual‐Channel Self‐Reporting

open access: yesAdvanced Science, EarlyView.
An orthogonally programmable nanotheranostic (MB@YW NPs) enables precision therapy for rheumatoid arthritis. A triple‐locked (pH, HOCl/ONOO−, light) independently drives the release of methotrexate and sulfasalazine. Trackable by dual‐channel fluorescence, this coordinated drug delivery remodels the inflammatory microenvironment to markedly suppress ...

Dynamic Supercooled Crystal–Gels for Ultrafast, Reversible Mechanical Adaptative Materials

open access: yesAdvanced Science, EarlyView.
A dynamic supercooled crystal–gel mimics starfish tissue by storing non‐equilibrium energy in a metastable liquid. A gentle touch triggers templated crystallization, producing a 2596‐fold stiffness increase with negligible volume change. The lattice disintegrates reversibly under humidity or warmth.
