The limitations of conventional electromagnetic wave (EMW) absorbing materials in terms of high-temperature resistance have stimulated interest in the development of high-temperature EMW absorbing materials across various fields. However, due to the temperature dependence of the permittivity, achieving effective EMW absorption across a wide temperature range remains a significant challenge for high-temperature EMW absorbing materials. Herein, a novel molecular-scale strategy is proposed for in-situ construction multi-heterointerface during the polymer-derived ceramics process, thereby achieving temperature-insensitive permittivity. This approach to developing temperature-insensitive dielectric ceramics significantly improves the performance and functionality of high-temperature EMW absorbing materials, thereby providing substantial guidance and reference value.
Dissolved organic matter (DOM) plays a critical role in nutrient cycling and microbial dynamics across ecosystems, but its complexity poses major analytical challenges. To address this, a team led by Prof. Jianjun Wang from the Chinese Academy of Sciences has developed iDOM, a powerful new R package for the statistical analysis and visualization of DOM data. Designed to integrate DOM composition with environmental and microbial factors, iDOM enables researchers to unravel the ecological processes driving DOM dynamics under global change. With tools for trait analysis, diversity metrics, network inference, and temperature response modeling, iDOM offers a robust and reproducible framework for DOM studies worldwide.
Second primary cancers (SPCs) are a major cause of death among cancer survivors. This review highlights recent advances in understanding SPC mechanisms, including genomic changes, stromal cell alterations, hormone signaling, immunosuppression, and gene methylation. It also explores emerging tools such as intratumoral microbes, single-cell multi-omics, and metabolomics, offering new directions for future research.
Artificial intelligence (AI) is transforming healthcare across multiple fields, and prostate cancer (PCa) is no exception. A recent review conducted by researchers discusses the role of AI in clinical practice against PCa. According to this study, AI models enable early detection of PCa with high accuracy while minimizing errors. AI models used in molecular subtyping and precision medicine also offer personalized treatments—improving the overall quality of life of patients.
This study addresses the critical gap in epidemiological data on antenatal depression in China, a condition that profoundly impacts maternal and infant health. Conducted as a cross-sectional survey from December 2019 to March 2023, the research enrolled 100,200 pregnant women across 27 hospitals in 11 provinces, municipalities, and autonomous areas. Late-pregnancy depressive symptoms were evaluated using the Edinburgh Postnatal Depression Scale (EPDS). This survey reveals that the overall prevalence of possible depression (EPDS >9) was 25.8%, and probable depression (EPDS >12) was 11.4%, with significant regional variation (highest in North China, lowest in East China). Young maternal age, low education levels, low family income, unemployment, living alone, unmarried/divorced status, unintended pregnancy, multiple pregnancy, insufficient social support, tobacco/alcohol use, and poor sleep quality were identified as risk factors for antenatal depression. Notably, family support, particularly from partners, emerges as a pivotal intervention target for reducing antenatal depression risk.
Professor Chuang Yu from Huazhong University of Science and Technology significantly enhanced the air stability of chlorine-rich Li₅.₅PS₄.₅Cl₁.₅ electrolyte and improved the electrochemical performance of all-solid-state lithium metal batteries through a phosphate group doping strategy.
Boron-based compounds are known as a class of anion acceptors. Now, writing in the journal Science China Chemistry, a team of researchers from Nankai University use this chemistry in electrolyte design. According to the study, boron-based additives have been found to reduce charge transfer resistance, improve the Li-ion diffusion kinetics, and stabilize high-voltage cathode of batteries. The findings demonstrated versatileness of B-ads that effectively mitigated the critical challenges of energy-dense battery systems.
Recently, a research team led by Professor Caifu Jiang from China Agricultural University published a study titled "The ZmMPK3-ZmGRF1 module promotes maize growth by enhancing cell proliferation under salt stress" in Science Bulletin. This study shows that the ZmMPK3-ZmGRF1 module facilitates maize growth under salt stress through enhanced cell proliferation, providing new insights into how MPK signaling pathways and GRF growth regulators govern plant responses to saline environments. Furthermore, these findings offer valuable genetic resources for developing salt-tolerant maize varieties.
