Dual Randomness From Spatial and Temporal Variations in Stochastic Zinc Gallate Nanoclusters for PUF and TRNG Co‐Driven Image Generation

Advanced Science, EarlyView.
A dual‐randomness hardware platform is demonstrated by integrating PUF and TRNG functionalities into mixed‐ZGO nanoclusters. By leveraging spatial and temporal stochasticity, the mixed‐ZGO NCs device enables both unique identification and random signal generation.

PBRM1 Deficiency in Microglia Leads to Excessive Neurogenesis and Autism‐Like Behaviors via the CCL5‐CCR1/5‐β‐catenin Signaling Axis

Advanced Science, EarlyView.
Microglial PBRM1 deficiency drives excessive hippocampal neurogenesis by enhancing CCL5–CCR1/5 signaling, leading to autism‐like behaviors. A pro‐inflammatory IL1α+/TNFα+ microglial subset is identified as a key cellular contributor to this process. PBRM1 represses Ccl5 expression at the transcriptional level.

In Vivo CRISPR Screen Identifies RPS19 as an Immunotherapy Target in Hepatocellular Carcinoma

Advanced Science, EarlyView.
By employing in vivo CRISPR functional screening, we identify ribosomal protein RPS19 as a pivotal mediator driving immune evasion in hepatocellular carcinoma, wherein tumor‑released RPS19 binds C5aR1 on tumor‑associated macrophages to initiate downstream immunosuppressive signaling; SP94‑peptide‑modified SNPSS nanoparticles deliver Cas9/sgRPS19 ...
