scpFormer is a transformer-based foundation model created to unify and interpret fragmented single-cell proteomics data across various technologies and experimental designs. To overcome the lack of universal reference panels, the model employs a continuous semantic tokenization strategy that maps proteins to a shared space using their amino acid sequences. This innovative architecture allows the s...

This research explores how genome-wide selective sweeps (GWSSs) act as a fundamental evolutionary mechanism to organize the human gut microbiome into distinct ecological units. By analyzing thousands of bacterial genomes and metagenomes, the authors identified 124 confirmed sweep clusters across 66 different taxa, revealing that these populations can spread globally within decades. The study demon...

This research identifies the tumor suppressor p53 as an indispensable driver of human chemical reprogramming, reversing its known role as a barrier in traditional transcription factor-based methods. While suppressing p53 helps create stem cells using the Yamanaka factors, doing so in chemical reprogramming leads to excessive EMT and prevents cells from reaching a pluripotent state. Small molecules...

This review article examines the complex landscape of regulated cell death and its critical role in cancer development, progression, and treatment. While apoptosis has long been the primary focus of oncology, the authors highlight how emerging pathways like necroptosis, pyroptosis, and ferroptosis provide new opportunities to overcome therapy resistance. These diverse death programs do not functio...

This comprehensive review defines the burgeoning field of cancer neuroscience, which explores the bidirectional relationship between the nervous system and malignant tumors.

This research introduces a large-scale dataset of breast and lung tumor sections to evaluate the performance and technical hurdles of Xenium spatial transcriptomics. The authors identify transcript spillover—the misassignment of genetic signals between neighboring cells—as a primary driver of data noise that blurs cell-type boundaries. To address this, they developed SPLIT (Spatial Purification of...

The paper introduces eSIG-Net, a novel interaction language model designed to predict how single missense mutations disrupt protein-protein interactions (PPIs). Unlike traditional tools that rely on static structures or basic sequences, this framework utilizes mutation-centric encoding and constrained discrepancy learning to identify subtle "interaction cliffs" where tiny genetic changes cause mas...

The paper introduces MicroSplit, a deep learning-based method designed to enhance fluorescence microscopy by enabling computational multiplexing. By training Variational Splitting Encoder-Decoder networks, researchers can image multiple cellular structures simultaneously in a single fluorescent channel and then digitally unmix them into separate, denoised images. This innovation addresses the "tri...

This study presents a comprehensive biochemical profile of 92 clinical kinase inhibitors—86 of which are FDA-approved—tested against a panel of 758 kinases. By examining 409 wild-type and 349 oncogenic variants, the researchers expanded the known landscape of druggable kinases from 89 to 235. The results reveal significant polypharmacology, demonstrating that most approved drugs inhibit additional...

This study identifies a novel immune process where macrophages directly sample material from living cells without causing them harm. Unlike the traditional view that immune cells primarily gather self-antigens from dying tissue, researchers discovered a contact-dependent mechanism similar to trogocytosis that extracts submicrometre-sized cytoplasmic vesicles. Using advanced lattice light-sheet ima...

The article examines the evolution of three-dimensional genome organization by analyzing Hi-C data from over 1,000 diverse species. Researchers identified two primary higher-order architectures: "global folding," which dictates the spatial arrangement of whole chromosomes, and "checkerboard," which represents the compartmentalization of chromatin. The study reveals that animals developed more comp...

This review examines the evolutionary mechanisms of cancer development, focusing on the critical distinction between tumour initiation and tumour promotion. While traditional research emphasizes genetic mutations as the primary cause, the authors highlight that many carcinogens are not actually mutagens but instead act as promoters that encourage pre-existing mutant cells to expand. By integrating...

Scientists have developed a comprehensive spatial atlas of the human kidney to better understand the cellular architecture of diabetic kidney disease (DKD). By integrating high-resolution single-cell transcriptomics with existing genomic data, researchers identified specific tissue niches and microenvironments that change as the disease advances. A significant discovery was a unique B cell-rich im...

This review article examines the evolution of de novo protein design, highlighting a significant transition from physics-based models to deep-learning-powered methodologies. The authors describe how advanced tools like RFdiffusion and ProteinMPNN allow scientists to build entirely new protein structures from scratch rather than modifying existing ones found in nature. By leveraging generative arti...

The paper details the emergence of intelligent and miniaturized drug delivery devices (IMDDDs), which represent a significant shift toward personalized and autonomous medicine. By integrating artificial intelligence, electronics, and advanced materials, these systems move beyond traditional dosing to provide real-time sensing and adaptive, closed-loop drug administration. The sources categorize th...

Recent breakthroughs in biofluid-based biomarkers are fundamentally altering the diagnosis and clinical management of Alzheimer's disease and other neurodegenerative conditions. Advanced technologies now enable the detection of specific proteins, such as amyloid-β, tau, and neurofilament light, in blood and cerebrospinal fluid to reflect ongoing brain pathology. These molecular tools facilitate ea...

Research highlights a groundbreaking discovery that physical tissue stiffness acts as a direct catalyst for genetic mutations in cancer. This process begins when a rigid extracellular environment triggers a cellular chain reaction, signaling epithelial cells to recruit inflammatory macrophages. These immune cells respond to the mechanical pressure by releasing genotoxic aldehydes and reactive oxyg...

This research identifies a novel communication pathway where activated T cell-derived extracellular vesicles (ATEVs) enhance the body’s ability to recognize and destroy tumors. These vesicles carry double-stranded genomic DNA enriched with immune-related genes, which they deliver directly into the nuclei of dendritic and cancer cells. This transfer is facilitated by granzyme B, a protein within th...

This research explains how physical tissue tension within a fibrotic microenvironment drives cancer development and progression. The study demonstrates that stromal stiffness activates the STAT3 signaling pathway, which recruits macrophages to the tumor site. Once present, these macrophages react to the high-pressure environment by producing reactive oxygen species and lipid-derived aldehydes. The...

This research identifies a conserved genetic program called MP10 that drives the transition of benign pancreatic lesions into invasive pancreatic ductal adenocarcinoma (PDAC). Mirroring the process of cutaneous re-epithelialization used in skin wound healing, this program enables cancer cells to breach the basement membrane and infiltrate surrounding tissues. The transcription factor FOSL1 acts as...
