Auditory Hair Cell Mechanotransduction Channels Dynamically Shape the Mechanical Properties of Their Membrane Environment

open access: yesAdvanced Science, EarlyView.
This work shows, for the first time, that the stereocilia membrane in cochlear hair cells is dynamically regulated by the mechanotransduction channel to impact the membrane mechanical properties. This work provides direct evidence that the opening and closing associated with the MET channel is regulating the membrane viscosity suggesting that the MET ...

Shear Conditioning Promotes Microvascular Endothelial Barrier Resilience in a Human BBB‐on‐a‐Chip Model of Systemic Inflammation Leading to Astrogliosis

open access: yesAdvanced Science, EarlyView.
Physiological flow (0.5 Pa) conditioning promotes resilience of an iPSC‐derived blood–brain barrier endothelium to mild systemic inflammation. In contrast, high “cytokine storm” levels induce barrier breakdown, fibrinogen leakage, and astrocyte activation, reconstituting the two‐hit injury mechanism on‐a‐chip.

cGAS Inhibits ALDH2 to Suppress Lipid Droplet Function and Regulate MASLD Progression

open access: yesAdvanced Science, EarlyView.
cGAS is a cytosolic DNA sensor known for innate immune defense. cGAS binds and suppresses ALDH2 are showed, limiting acetyl‐CoA production. cGAS loss activates ALDH2, promoting histone acetylation, lipogenesis, and lipid droplets accumulation. cGas‐/‐ mice on a high‐fat diet show signs of worsened MASLD.

Switchable Bidirectional Sound Absorption Via Exceptional Point Modulation in Acoustic Metastructures with Interleaved Resonator Coupling

open access: yesAdvanced Science, EarlyView.
A switchable bidirectional acoustic metastructure is proposed, enabling broadband and frequency‐selective absorption via interleaved resonator coupling and exceptional point modulation. It outperforms traditional unidirectional designs, offering compact, efficient sound control from both directions and establishing a generalized framework for extending

Single Mitochondrion Morphology‐Function Relationship Analysis Using Fluorescent Probes and Artificial Intelligence

open access: yesAdvanced Science, EarlyView.
An integrated strategy combining a mitochondria‐targeted fluorescent probe set and an AI framework enables simultaneous analysis of mitochondrial morphology and function at the single organelle level. By fusing multi‐parametric features, machine learning classification accurately distinguishes individual mitochondria under hypoxia‐related conditions ...
