Cavity as radio telescope for galactic dark photon.

Dark photons, as a minimal extension of the Standard Model through an additional Abelian gauge group, may propagate relativistically across the galaxy, originating from dark matter decay or annihilation, thereby contributing to a galactic dark photon background. The generation of dark photons typically favors certain polarization modes, which are dependent on the interactions between dark matter and dark photons. We introduce a framework in which a resonant cavity is utilized to detect and differentiate these polarizations, leveraging the daily variation in expected signals due to the anisotropic distribution of dark photons and the rotation of the Earth.

Photocatalytic Conversion of Methane to Ethane and Propane Using Cobalt-Cluster-Activated GaN Nanowires.

The photocatalytic nonoxidative coupling of methane (PNOCM) offers a promising route to synthesize valuable C2+ hydrocarbons while minimizing side reactions. Oxide-based photocatalysts have been predominant in this field, but suffering from limited conversion rates, selectivity, and durability due to poor C-C coupling as well as overoxidation of CH4 by lattice oxygen. Here, we introduce an advancement in PNOCM for methane conversion into ethane and propane using GaN, one of the most produced semiconductors, together with trace amounts of metallic cobalt clusters (0.

Exploration of the Biological Function of Ferroptosis in Bone Nonunion: An Analysis of Bioinformatics Combined Mendelian Randomization.

To deeply investigate the mechanism of ferroptosis-related genes in the process of bone nonunion based on the GEO database. And using Mendelian randomization to explore the causal association of 15 trace elements with the occurrence of bone nonunion. Bone nonunion RNA-seq data were retrieved and downloaded from the GEO database.

Hyperacute rejection-engineered oncolytic virus for interventional clinical trial in refractory cancer patients.

Recently, oncolytic virus (OV) therapy has shown great promise in treating malignancies. However, intravenous safety and inherent lack of immunity are two significant limitations in clinical practice. Herein, we successfully developed a recombinant Newcastle disease virus with porcine α1,3GT gene (NDV-GT) triggering hyperacute rejection.

Chitosan functionalized two-dimensional covalent organic framework nanosheets with high hydrophilicity for efficient glycopeptide enrichment.

Glycopeptides are an important biomarker, which play a crucial role in various biological processes. Due to their low abundance and the presence of interfering macromolecular proteins, enrichment of glycopeptides is necessary before testing. However, most materials for enriching glycopeptides have high site resistance, relatively low surface area, and limited recognition sites.
