▲ Abstract：

The evolutionary history of domesticated cattle in East Asia for the past 5000 years remains largely obscure. Here, we investigated the origins and evolution of cattle genetic diversity in China by analyzing shotgun genome sequences of 166 ancient bovines spanning a 10,000-year period and encompassing now-extinct East Asian aurochs and domesticated cattle from key archaeological cultures. East and North Asian aurochs were distinct from western aurochs, although East Asian aurochs harbored approximately 15% western ancestry. The first domesticated cattle in the Yellow River region derived approximately 10% of their ancestry from local aurochs with an uneven genome-wide distribution. Early cattle from Xinjiang were genetically distinct and partially contributed to the later northern Chinese cattle. Indicine admixture became widespread only in the Medieval period in northern China.

▲ Abstract：

Plant cell walls harbor vast carbohydrate reserves, yet how pathogens unlock them remains unclear. We show that the citrus canker pathogen Xanthomonas citri subsp. citri (Xcc) mobilizes cell wall sugars by hijacking a fruit-ripening program through the type III effector PthA4, which activates the ripening coordinator CsLOB1. CsLOB1 induces approximately 100 genes, many encoding enzymes involved in cell wall breakdown. In the nonfruiting species Nicotiana benthamiana, CsLOB1 likewise promotes Xanthomonas growth, showing that its activity is not strictly dependent on a ripening program. Transcriptomics and reporter assays revealed PthA4-dependent activation of the Xcc xylan CUT system, triggered by host-derived xylose and including a type II–secreted xylanase. Thus, PthA4-driven cell wall remodeling activates bacterial xylan use, establishing a TIII–TII effector feedforward loop that fuels Xcc proliferation.

▲ Abstract：
The human blood proteome provides a holistic readout of health states through the assessment of thousands of circulating proteins. In this study, we present a pan-disease resource to enable the study of diverse disease phenotypes within a harmonized proteomics dataset. By profiling protein concentrations across 59 diseases and healthy cohorts, we identified proteins associated with age, sex, and body mass index, as well as disease-specific signatures. This study highlights shared and distinct protein patterns across conditions, demonstrating the power of a unified proteomics approach to uncover biological insights. The dataset, covering 8262 individuals and up to 5416 proteins, serves as an online resource for exploring disease-specific protein profiles and advancing precision medicine research.

▲ Abstract：
Cancer stem cells (CSCs) represent a self-renewing population capable of fueling long-term tumor growth. In gastric cancer, the identity of CSC populations remains unclear. In this study, we established a gastric CSC population marked by the water channel protein aquaporin-5 (AQP5), which resides in human and mouse pyloric tumors. Using multiple organoid and mouse models, we found a requirement for AQP5+ CSCs in both initiating and sustaining cancer progression and demonstrated that AQP5 expression also directly promotes tumor growth and invasion in a WNT, PI3K (phosphatidylinositol 3-kinase), and MAPK (mitogen-activated protein kinase)–dependent manner. Beyond primary cancers, AQP5 further enriches for a functional CSC population in metastatic tumors. Together, our findings support a CSC model in gastric tumors that may have application for therapeutic strategies targeting CSCs.

▲ Abstract：
Visceral pain disorders, such as irritable bowel syndrome, exhibit a marked female prevalence. Enhanced signaling between enterochromaffin (EC) cells in the gut epithelium and mucosal sensory nerve fibers likely contributes to this sex bias. We identified an estrogen-responsive paracrine pathway in which two enteroendocrine cell types, peptide YY (PYY)–expressing L cells and serotonergic EC cells, communicate to increase gut sensitivity in females. We demonstrate that estrogen signaling up-regulates the bacterial metabolite short-chain fatty acid receptor Olfr78 on colonic L cells, increasing PYY release and their sensitivity to acetate. Elevated PYY acts on neighboring EC cells by means of NPY1R, thereby enhancing serotonin release and gut pain. We propose that hormonal fluctuations, in conjunction with internal (stress) or environmental (diet) factors, amplify this local estrogen-responsive colonic circuit, resulting in maladaptive gut sensitivity.

▲ Abstract：

Achieving conformal, vapor-deposited perovskite films on industry-standard textured silicon substrates with micrometer-scale pyramids remains challenging because of the complex surface partitioning of perovskite vapors and the effects of nonequilibrium organic and inorganic vapor adsorption. We incorporated 3,3,3-trifluoropropyl-trimethoxysilane to enhance substrate-organic interactions, thereby optimizing surface partitioning and balancing adsorption of perovskite vapors. Vertically uniform perovskite films with minimal phase impurities formed, and nanobeam diffraction confirmed formation of the perovskite cubic phase across different pyramid regions. The resulting tandem devices achieved a power conversion efficiency of 31.3% (1 square centimeter aperture area) and exhibited excellent operational stability, retaining 90% of their initial performance after 1400 hours of continuous 1-sun illumination at 85°C.
