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

open access: yesAdvanced 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

A Non‐Mitophagy Activity of BNIP3L/NIX in Amygdala Glutamatergic Neurons is Essential for Contextual Fear Memory Formation

open access: yesAdvanced Science, EarlyView.
Contextual fear conditioning induces BNIP3L‐dependent mitochondrial fission in glutamatergic neurons of the BLA, independently of mitophagy. Loss of BNIP3L elevates Drp1Ser637 phosphorylation, thereby suppressing mitochondrial fission, compromising ATP production, and attenuating excitatory synaptic transmission.

Periodontitis Induces B Cell‐Macrophage Crosstalk to Exacerbate Glucose Dysregulation in Obesity

open access: yesAdvanced Science, EarlyView.
In obesity, periodontitis exacerbates hyperglycemia and exhibits a liver‐centric preference for glucose regulation. This occurs through a periodontitis‐driven circuit between pathogenic B cells and hepatic macrophages. Their reciprocal expansion, orchestrated by the NLRP3/IL‐18 signaling pathway, amplifies metabolic inflammation and disrupts glucose ...

Multicohort Validation of Gut Microbiome Signatures for Cholangiocarcinoma Diagnosis and Functional Characterization of Bifidobacterium Pseudocatenulatum

open access: yesAdvanced Science, EarlyView.
This study analyzes gut bacteria in cholangiocarcinoma patients, revealing distinct microbial signatures that enable accurate disease detection. Species‐based diagnostic models achieved over 98% accuracy in identifying cholangiocarcinoma and distinguished it from other liver diseases. The research demonstrates that specific beneficial bacteria suppress

Spatiotemporal Organization of PTK7 Diffusion on Cell Surface Facilitates Tumor Invasion and Migration

open access: yesAdvanced Science, EarlyView.
The spatiotemporal dynamics of protein kinase diffusion govern cellular signaling and functions. Although vital for active receptors, the role of pseudokinase dynamics is unclear. Here, we use single‐molecule tracking to link faster diffusion of pseudokinase PTK7 to increased tumor cell invasion and migration.
