TRIM40 Drives Pathological Cardiac Hypertrophy and Heart Failure via Ubiquitination of PKN2

Advanced Science, EarlyView.
This study identifies the E3 ligase TRIM40 as a key driver of pathological cardiac hypertrophy. TRIM40 binds PKN2 via its B‐box domain and, through its C29‐dependent catalytic activity, mediates K63‐linked ubiquitination of PKN2. This modification enhances PKN2 phosphorylation at Ser815, thereby driving hypertrophy.

A Cascade Recognition of Activatable Probe for Fluorescence Navigation Glioblastoma Surgery: Overcoming Blood‐Brain Barrier and Off‐Target Limitations

Advanced Science, EarlyView.
A cascade recognition of activatable probe ANG‐hCy‐MC is used for high‐precision depiction of glioblastoma (GBM) margin. This probe crosses the blood‐brain barrier (BBB) through LRP1 receptor‐mediated transport and provides excellent fluorescence signal contrast between the tumor and normal tissues, thereby enabling ultra‐selective imaging and precise ...

Smart Optogenetics for Real‐Time Automated Control of Cardiac Electrical Activity

Advanced Science, EarlyView.
We are able to stop dangerous heart‐rhythm spirals before they fully form. Within about 100 ms, it pinpoints the spiral's tiny central tip (≈0.9 mm) using light‐based sensing and machine learning, then shines targeted light to shut it down. This fast, precise, closed‐loop approach detects, targets, and terminates arrhythmias in real time.

Water‐Assisted Exfoliation of HfO2‐Based Membrane for Flexible Robust Ferroelectric Synaptic Transistors

Advanced Science, EarlyView.
A flexible freestanding HfO2‐based ferroelectric membrane is achieved via a water‐assisted exfoliation technique using a Sr4Al2O₇ sacrificial layer. The BaTiO3/Hf0.5Zr0.5O2/BaTiO3 heterostructure maintains robust ferroelectricity and exhibits reliable synaptic plasticity.

Discovering Interpretable Semantics from Radio Signals for Contactless Cardiac Monitoring

Advanced Science, EarlyView.
This study presents a semantic representation framework for clinically interpretable cardiac monitoring from contactless radio signals. It formulates radio semantic learning as an information‐bottleneck problem and approximates the objective via intra‐modal compression and cross‐modal alignment, structuring radio measurements into meaningful semantic ...

Bioinspired Cold‐Laminated Ultrathin Hydrogels as a Broadly Adaptive Platform for Physiological Monitoring

Advanced Science, EarlyView.
A cold‐lamination strategy is introduced to fabricate ultrathin, nanomesh‐reinforced hydrogel bioelectronics with controlled thickness, tunable mechanics, and reversible adhesion. By mechanically interlocking a TPU nanomesh within a temperature‐responsive hydrogel, the platform enables robust epidermal and implantable cardiac interfaces, supporting ...
