Detecting electrolyte leakage is an effective early warning approach for abnormal faults in lithium-ion batteries (LIBs). However, LIBs produce volatile organic compounds at ppm levels that are difficult to “sense”. Scientist in China proposed a micro-nano fiber sensor coated with in-situ self-assembled ZIF-8 membrane. The sensor can “sense” the LIBs leaks with high-sensitivity, achieving early warning 35 hours before battery load stop. The technique will open new avenues for future electric vehicle battery safety monitoring.

Scientists have achieved a significant leap in aqueous Mg-ion battery technology by engineering a breakthrough cathode material (nickel oxide hydroxide (NiOOH)), and systematacially reveal the stable Mg-storage mechanism in NiOOH nanosheets. This innovative design significantly enhances aqueous Mg-ion battery performance, resolving long-standing challenges of balancing high voltage and high capacity. The achievement paves the way for a safer, more versatile energy storage solution, poised to meet the growing demands of next-generation devices.

Scientists have developed ultralight and ultrathin copper current collectors that could redefine lithium battery technology. These collectors, far lighter than traditional copper foils, significantly enhance cell-level energy density. This leap forward in efficiency and weight reduction is poised to transform the performance of portable electronics and electric vehicles, where lightweight, high-capacity batteries are crucial for progress.

Researchers at Tel Aviv University developed a groundbreaking method to synthesize spatial coherence during nonlinear optical interactions, enabling the creation of structured light beams and spatial coherence patterns, such as a smiley-face shape, through second-harmonic generation. This novel approach bridges incoherent light and nonlinear optics, paving the way for advancements in infrared imaging, structured beam shaping, and optical communications. 

Scientists from the Institute of Tibetan Plateau Research, Chinese Academy of Sciences (CAS) have compared several methods for plant diversity reconstruction using pollen data. By analyzing modern pollen distributions across China, the team calculated angiosperm diversity using five key ecological indices and—for the first time—applied an image similarity algorithm (SSIM) to validate their findings. Their work not only identifies the most reliable indicators for tracking biodiversity changes but also reveals how climate factors, particularly winter temperatures, shape plant distributions—a critical insight for conservation in the face of climate change.

Travel demand prediction is a crucial component in the formulation of transportation planning, urban planning, regional development planning, and serves as a key basis for the investment and construction of transportation infrastructure. Current prediction technologies generally lack systemic consideration, neglecting the interactions between transportation and elements such as population, land use, and housing, making it difficult to meet the increasingly complex analytical needs of urban planning and decision-making. To address this challenge, a research team from College of Urban and Environmental Sciences, Peking University and School of Urban Planning and Design, Peking University Shenzhen Graduate School has proposed an integrated land-population-housing-transportation simulation technology framework, developing an urban system-based travel demand simulation and prediction technology. Journal of Geo-Information Science has published the study's achievement.

Researchers from East China University of Science and Technology investigated the influence of hydrothermal carbonization (HTC) on sewage sludge-derived hydrochar for coal-water slurry (CWS) performance. Results show that HTC improves slurry stability and reduces ash content, with optimal conditions identified for enhanced gasification reactivity.

This case report presents a 33-year-old man with primary infertility and obstructive azoospermia associated with tubular ectasia of rete testis (TERT). The patient had normal testicular spermatogenesis, but sperm could not be ejaculated. The authors conducted a literature review, discussing the multiple causes of TERT, including post-infectious, trauma, and congenital malformation. TERT is usually asymptomatic and benign. Although it may be related to abnormal semen analysis, its exact impact on fertility requires further study.

This review explores the multifaceted relationship between testosterone and men's health. Testosterone is essential for male physiological development, including sexual differentiation and the development of secondary sexual characteristics. Abnormal levels, whether high or low, are associated with various health issues, such as hypogonadism, cardiovascular diseases, and metabolic disorders. Precision medicine offers personalized treatment options, and biomarkers help in accurate diagnosis and monitoring. Despite the potential of testosterone therapy, research has limitations. Future studies are required to optimize treatment and better understand its long-term effects.

This scoping review examines the impact of Rezum therapy on sexual function in patients with benign prostatic hyperplasia (BPH). Analyzing 15 studies with 2,425 patients, the review finds that Rezum therapy generally preserves or improves sexual function, with minimal negative effects on erectile and ejaculatory function. These findings highlight Rezum as a favorable treatment option for BPH, especially for patients prioritizing sexual function preservation. Further research comparing Rezum with other treatments is recommended.
