  "account": "Researchers have developed a novel method called Spectrum-FISH for analyzing RNA in fresh tissue samples without the need for sequencing or amplification. Led by Professor Shi Peng at City University of Hong Kong, the team's approach uses vertically aligned nanoneedle arrays to directly profile messenger RNAs, microRNAs, and RNA methylation in freshly prepared tissues. Unlike traditional spatial omics technologies, Spectrum-FISH eliminates the need for extensive tissue pretreatment, making it more accessible and affordable for routine clinical use. The method preserves spatial information through a registration strategy, allowing researchers to map molecular signals back to tissue structures and cells. Tests on mouse neural tissues and human colorectal biopsies showed that Spectrum-FISH can maintain high-resolution molecular mapping while minimizing tissue processing and assay costs. This breakthrough has significant implications for making spatial omics technologies more practical and widely applicable in clinical settings, potentially transforming the way we understand and treat various diseases.",
  "summary": "Recently, spatial omics has become a powerful tool, enabling researchers to see not only what molecules are present in a tissue, but also where they are located and how they are organized across cells, tissue structures and local microenvironments. This spatial context has deepened our understanding of cancer, neurobiology and immunology. Yet as the field advances, an important question remains:…",
