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

Disorder‐Induced Extremely Low Thermal Conductivity of Graphite Fluoride
Advanced Science, EarlyView.This article investigates the effect of fluorination on the thermal conductivity of graphite fluoride, demonstrating the relationship between structural modification and thermal conductivity in an extreme case. The record‐low through‐plane thermal conductivity measured in exfoliated graphite fluoride flakes was found to correlate with the wide ...

Advanced Science, EarlyView.Cell‐sized high‐frequency ultrasound using a lithium niobate transducer, previously ignored in reactive oxygen species (ROS) production, generated intracellular ROS at frequencies higher than conventionally used. The intracellular generation of ROS by cell‐sized high‐frequency ultrasound revealed in this study is expected to be applied to innovative ...

Advanced Science, EarlyView.A programmable 2048‐element circular ultrasound array combined with a compact acoustic lens produces a thin “sound sheet” over a large field of view, and records echoes with wide angular diversity across the ring aperture. Coherence‐enhanced beamforming converts full‐matrix data into high‐contrast tomographic slices, delivering near‐diffraction‐limited

Restoring Iron Homeostasis via Smoothened Inhibition: A Novel Strategy Against Hearing Loss
Advanced Science, EarlyView.. ABSTRACT Sensorineural hearing loss (SNHL) induced by noise or aminoglycoside antibiotics is a significant public health concern without any FDA‐approved pharmaceutical therapies. Dysregulation of iron homeostasis and its subsequently induced ferroptosis has increasingly been identified as a key mechanism underlying cochlear hair cell (HC) damage ...
