Nanoscopic Imaging the Lithiation of Sulfur Nanoparticles under Electron Beam Irradiation

Advanced Science, EarlyView.
ABSTRACT In situ Transmission Electron Microscopy (TEM) provides powerful insights into the reaction mechanisms of Lithium‐Sulfur (Li‐S) batteries. However, distinguishing intrinsic electrochemical behaviors from artifacts induced by high‐energy electron beam irradiation remains a critical challenge.

Origin of the unique topology of the triangular water cluster in Rubrobacter xylanophilus rhodopsin

Biophysics and Physicobiology
The crystal structure of Rubrobacter xylanophilus rhodopsin (RxR) reveals a triangular cluster of three water molecules (W413, W415, and W419) at the extracellular proton-release site, near Glu187 and Glu197.

PVNCRF Neurons Regulate Migraine‐Like Allodynia by Activating CRFR2 on Spinal Trigeminal Caudalis Glutamatergic Neurons

Advanced Science, EarlyView.
Paraventricular CRF neurons in the hypothalamus project to glutamatergic neurons of the spinal trigeminal caudal nucleus, enhancing neuronal activation and CRFR2 signaling. This pathway increases CRF release and excitatory drive, promoting central sensitization and migraine‐related behaviors. Targeting the PVN–SP5C circuit provides a potential strategy

Combining the Pitcher and Lotus Plant: Supericephobic and Superhydrophobic Silicone Films

Advanced Science, EarlyView.
Based on bench‐top nanomolding of polydimethylsiloxane (PDMS) with optimized silicone oil content, we developed hierarchically structured silicone films by essentially combining the properties of the lotus and pitcher plant; particularly we are able to achieve water contact angle as high as 171° and ice adhesion strength as low as 11.5 kPa (i.e ...

T Cell Exhaustion in Cancer Immunotherapy: Heterogeneity, Mechanisms, and Therapeutic Opportunities

Advanced Science, EarlyView.
T cell exhaustion limits immunotherapy efficacy. This article delineates its progression from stem‐like to terminally exhausted states, governed by persistent antigen, transcription factors, epigenetics, and metabolism. It maps the exhaustion landscape in the TME and proposes integrated reversal strategies, providing a translational roadmap to overcome

Rapid and Direct Detection of Methamphetamine in Biofluids using a MXene‐Enabled Electrochemical Sensor

Advanced Science, EarlyView.
A MXene‐enhanced electrochemical sensor enables the rapid and direct detection of methamphetamine. Molecular simulations reveal that specific MXene surface functional groups act as key signal amplifiers by facilitating interfacial interactions. The sensor demonstrates high sensitivity and robust performance in complex biological matrices.

Spatiotemporal profiling of protein kinase A activity in spontaneously beating hiPSC-derived cardiac organoids

iScience
Summary: Protein kinase A (PKA) phosphorylates proteins crucial for rhythm modulation, with its dysregulation linked to arrhythmias. This study investigated PKA activity’s spatiotemporal dynamics in spontaneously beating cardiac organoids.

Understanding Fabrication Variability in Core‐Shell Soft Biomaterials Using Stochastic Artificial Intelligence

Advanced Science, EarlyView.
Fabrication‐induced variability remains a fundamental limitation in the scalable design of soft biomaterials. In this work, a stochastic machine learning approach based on Gaussian processes modeling is employed to establish quantitative links between biofabrication parameters, material properties, and their intrinsic variability.

The AKAP12-PKA axis regulates lipid homeostasis during alcohol-associated liver disease

Signal Transduction and Targeted Therapy
Disrupted lipogenic signaling and steatosis are key features of alcohol-associated liver disease (ALD). A-kinase anchoring protein 12 (AKAP12) is a scaffolding partner of the cAMP-dependent protein kinase, PKA that controls its spatiotemporal ...
