Direct Gravity‐Induced Modulation of Cardiac Conduction Pathways Evidenced Through Propagation Features in Electrophysiological Mapping

Advanced Materials Technologies, EarlyView.
A high‐density wearable body‐surface potential mapping array reveals how gravity reshapes cardiac conduction in real time. By resolving spatiotemporal delay patterns invisible to conventional ECG, the platform uncovers posture‐dependent electrophysiological adaptations across the thorax.

New Workflow of Plastic-Mulched Farmland Mapping using Multi-Temporal Sentinel-2 data

Remote Sensing, 2019
Using plastic film mulch on cropland improves crop yield in water-deficient areas, but the use of plastic film on cropland leads to soil pollution. The accurate mapping of plastic-mulched land (PML) is valuable for monitoring the environmental problems ...

Electrically Reconfigurable Nonvolatile Transmissive Metasurface in Visible

Advanced Optical Materials, EarlyView.
An electrically reconfigurable, non‐volatile metasurface operating in the visible spectrum is demonstrated using just 20 nm thick wide‐bandgap phase change material Sb2S3. On integration with a custom ultrathin silicon micro‐heater, the device achieves reversible switching with a 16 nm resonance tuning range at 610 nm, a wavelength largely under ...

Midbrain PAG Astrocytes Modulate Mouse Defensive and Panic‐Like Behaviors

Advanced Science, EarlyView.
Astrocytes in the midbrain periaqueductal gray (PAG) dynamically encode threat intensity and shape defensive action selection in mice. Real‐time Ca2+ imaging reveals robust astrocytic activation during predator odor and CO2 exposure. Aberrant astrocytic Ca2+ overactivation disrupts goal‐directed escape, biases behavior toward freezing, and induces ...

Magnesium hydroxide addition reduces aqueous carbon dioxide in wastewater discharged to the ocean

Communications Earth & Environment
Ocean alkalinity enhancement (OAE) reduces the concentration of dissolved carbon dioxide (CO2) in seawater, leading to atmospheric carbon dioxide removal (CDR).

Regulation of the tumor suppressor PML by sequential posttranslational modifications

Frontiers in Oncology, 2012
Posttranslational modifications (PTMs) regulate multiple biological functions of the PML (promyelocytic leukemia) protein and also the fission, disassembly and rebuilding of PML nuclear bodies (PML-NBs) during the cell cycle.

Role of PML and PML-RARα in Mad-Mediated Transcriptional Repression [PDF]

Molecular Cell, 2001
Fusion of the promyelocytic leukemia (PML) protein to the retinoic acid receptor-alpha (RARalpha) generates the transforming protein of acute promyelocytic leukemias. PML appears to be involved in multiple functions, including apoptosis and transcriptional activation by RAR, whereas PML-RARalpha blocks these functions of PML. However, the mechanisms of

Photon‐Sphere Modes in Curved Optical Microcavities: A Black‐Hole Analogue Laser

Advanced Science, EarlyView.
An optical analogue of a Schwarzschild black hole is realized using curved microcavities that preserve light‐like geodesics. A new family of laser modes confined around the photon sphere is identified alongside conventional whispering‐gallery modes. Analytical theory, numerical simulations, and experiments reveal curvature‐induced confinement, enabling

Visualizing and Quantifying Impact with Mechanochromic Sensing Paints Based on Self‐Assembled Polydiacetylene‐Silk Core‐Shell Vesicles

Advanced Science, EarlyView.
Tracking physical impacts is important in many fields. Self‐assembled microparticles made from polydiacetylene and silk fibroin that change color from blue to red when hit can provide an alternative approach to traditional mechanical transducers, quantitatively visualizing impact with responses ranging from <100 to 770 N.
