A Recyclable and Biodegradable High‐Performance Piezoelectric Nanogenerator for Self‐Powered Biosensing and Assistive Human‐Machine Interaction

Advanced Science, EarlyView.
By exploiting multiscale hydrogen‐bonding interactions between HFPD and TOCNF, the composite simultaneously achieves a high piezoelectric coefficient (14.0 pC·N−1), outstanding flexibility (100 000 bending cycles), water‐assisted recyclability, excellent biodegradability, and sensitive wearable/implantable sensing for motion, speech, and Morse code ...

Geometry‐Encoded Soft Strain Sensing via Liquid‐Metal Transmission Lines

Advanced Science, EarlyView.
This study presents a liquid‐metal transmission‐line strain sensor that achieves intrinsic decoupling by encoding axial elongation into propagation delay. The time‐domain readout remains stable under complex off‐axis. This enables reliable, repeatable, real‐time elongation measurement in dynamic, multiaxial loading environments for wearable electronics,

Head shoulders knees and toes [PDF]

Unexplained proximal muscle weakness in children can occur in some neurologic conditions and can be easily missed during exams that only focus on distal strength.When examining children with sudden limb, neck, or trunk weakness, remember head, shoulders,

Liquid‐Responsive Shape‐Memory Nanofiber‐Reinforced Scaffolds for Cartilage Repair

Advanced Science, EarlyView.
A liquid‐responsive shape‐memory, nanofiber‐reinforced QCG scaffold combines conformal defect filling, an aligned architecture that is structurally permissive for endogenous cell infiltration, and sustained KGN release. This integrated design enhances BMSC viability, migratory activity, and chondrogenic differentiation and promotes hyaline cartilage ...

Persistent Zn2+ Influx‐Mediated Deacetylation of ANXA2 Regulates the “Zn2+‐Autophagic Flux” and Alleviates Intervertebral Disc Degeneration

Advanced Science, EarlyView.
Zinc transporter SLC39A14 sustains intracellular Zn2+ levels to activate SIRT3‑dependent ANXA2 deacetylation at K302. This modification weakens ANXA2‑mTOR binding and releases autophagic‑flux suppression in nucleus pulposus cells. Dysregulated Zn2+ homeostasis disrupts this axis to drive intervertebral disc degeneration.

Nascent Extracellular Matrix Converts Biomaterial Cues into Cell Fate Decisions

Advanced Science, EarlyView.
This study uncovers a tri‐directional interplay among cells, hydrogels, and their nascent extracellular matrix. Hydrogel norbornene modification alters CD44‐mediated cell–hydrogel interactions, which shape nascent matrix deposition, composition, and spatial organization.
