March 03, 2026580-Planetary Microbiome and Generalist-Driven Gene Flow
This research presents a global framework for understanding the planetary microbiome by analyzing over 85,000 metagenomes to map how microbes are structured across diverse habitats. By integrating taxonomic and functional data, the study identifies generalist species that possess the unique metabolic versatility required to thrive in multiple, ecologically distinct environments. These generalists act as critical bridges, facilitating horizontal gene flow between disparate settings, such as the transfer of genes from human guts to wastewater and eventually into the broader environment. A key finding highlights how this connectivity drives the global dissemination of antimicrobial resistance (AMR) through specific genomic islands shared between generalists and specialists. The authors demonstrate that while environmental selection remains a primary driver of microbial community structure, human activities increasingly amplify the spread of clinical threats via these ecological mediators. Ultimately, this work provides a standardized model for monitoring global gene flow and predicting how anthropogenic pressures reshape the earth's microbial landscape.

March 03, 2026579-Oncolytic Virus Triggers Persistent T Cell Immunity
This research article investigates how a single oncolytic virus treatment can trigger a robust and lasting immune response in patients with recurrent glioblastoma. Using advanced spatial technologies like CODEX and Xenium, the authors demonstrate that the therapy causes T cells to infiltrate deeply into tumor regions, where they remain active for months or even years. The study highlights that the expansion of pre-existing T cell clones is a key driver of clinical success, directly correlating with improved patient survival outcomes. Notably, the remaining viral elements were found only in dead tissue, suggesting that the long-term anti-tumor activity is sustained by the immune system rather than the virus itself. However, the researchers also identified hypoxic tumor regions as significant barriers that exclude T cells and contribute to treatment resistance. These findings offer a precise spatial map of how immunotherapy can overcome the characteristically "cold" environment of brain cancer.

March 03, 2026578-A Single-Cell Atlas of Embryonic Endothelial Development
This research introduces the STED-EC atlas, a comprehensive single-cell transcriptomic resource mapping endothelial cell (EC) development across eight major organs during mouse embryogenesis. By analyzing these cells at half-day intervals, the authors identified that organ-specific vascular features primarily emerge during the mid-gestational stage. A comparison between mouse and human lung data revealed both evolutionary similarities and distinct gene expression patterns, highlighting the complexity of vascular specialization. The study specifically identifies the transcription factor Casz1 as a master regulator of pulmonary vascular growth. Through genetic experiments, the researchers demonstrated that Casz1 deficiency impairs lung development by disrupting the angiocrine signaling of FGF1, which is essential for proper epithelial cell proliferation. This work provides an interactive platform for investigating the molecular mechanisms that drive organotypic blood vessel differentiation and function.

March 03, 2026577-PocketXMol: Unified modeling of 3D molecular generation
They present PocketXMol, an atom-level model that unifies generative tasks related to protein pocket interactions. Using atomic prompts as task specifications, PocketXMol supports various molecular tasks, including structure prediction and de novo design of small molecules and peptides, without task-specific fine-tuning. PocketXMol achieved strong performance on 11 of 13 computational benchmarks and remained competitive on the remaining two, outperforming 55 baseline models. We applied PocketXMol to design caspase-9-inhibiting small molecules, achieving efficacy comparable with commercial pan-caspase inhibitors. We also adopted PocketXMol to generate PD-L1-binding peptides, resulting in a success rate that largely exceeds library screening. Three representative peptides underwent further experiments, which validated their cellular specificity and confirmed their potential for molecular probing and therapeutics. PocketXMol provides a general platform for AI-aided drug discovery and enables a wide range of future applications.

March 03, 2026576-Global Genomic Atlas of Infant Bifidobacterium infantis
This research presents a comprehensive genomic atlas of Bifidobacterium infantis and B. longum, proposing that they be reclassified as distinct species due to significant evolutionary and functional differences. By analyzing thousands of genomes from both industrialized and non-industrialized regions, the authors found that B. infantis strains exhibit extreme geographic stratification and specialize in metabolizing diverse breast milk components beyond just sugars. In contrast, current commercial probiotics often fail to persist in infants because they lack the local metabolic adaptations found in naturally circulating strains. The study also identifies specialized lineages in low-income countries that are better equipped to process traditional plant-based diets. Finally, the researchers provide optimized diagnostic tools and primers to help scientists more accurately identify these bacteria in clinical settings.

March 03, 2026575-Brain-Wide Atlas of Oligodendrocyte and Myelin Dynamics
This research introduces a sophisticated brain-wide mapping pipeline designed to analyze oligodendrocyte organization and myelin health across varying ages and disease states. By utilizing lightsheet microscopy and deep learning algorithms, the authors generated high-resolution atlases that reveal how myelin patterns are established and maintained throughout a mouse's lifespan. The study identifies specific regional vulnerabilities, noting that while some brain areas are resilient to injury, others, like the hippocampus, exhibit significant cell loss during demyelination. Integration with transcriptomic data further highlights how distinct neuronal factors and axon diameters influence the distribution of these essential cells. Additionally, the researchers investigated Alzheimer’s disease models, discovering that diffuse amyloid plaques cause substantial white matter damage independent of total plaque density. Ultimately, these comprehensive resources provide a foundational framework for understanding the complex dynamics of brain-wide myelination in both health and neurodegeneration.

March 02, 2026572-The Tumor-Immune-Neural Circuit Driving Cancer Cachexia
This research identifies a tumor-immune-neural circuit that drives cancer cachexia, a syndrome characterized by severe muscle wasting, fat loss, and appetite suppression. The study demonstrates that tumor cells release CSF1 to recruit macrophages, which then produce the hormone GDF15. This hormone signals through the brain’s GFRAL-RET axis to activate the sympathetic nervous system, releasing norepinephrine that further stimulates tumor growth and wasting in a self-amplifying loop. Researchers found that deleting GDF15 or using pharmacological inhibitors against components like CSF1R or RET effectively reverses these metabolic disruptions in mouse models. Ultimately, the findings suggest that targeting this tripartite interaction between the cancer, immune cells, and nervous system offers a promising therapeutic strategy for treating cachexia in human patients.
