Dynamic manipulation of optical signals between on-chip and free-space optical fields are highly pursued in various applications. Towards this goal, scientists in China proposed an addressable on-chip metasurface network on lithium niobate platform to present dynamic waveguide-based holographic display with improved multiplexing capability. Such scalable platform will advance holographic displays, high-capacity optical communication, and integrated photonic information processing, leveraging the potential of thin-film lithium niobate technology with high integration, fast response and high scalability.

A review study by Professor Weifeng Zhang from the College of Resources and Environmental Sciences, China Agricultural University, pointed out that stabilized fertilizers added with urease or nitrification inhibitors provide an effective path to solve this contradiction. China has achieved technological breakthroughs in this field and become a major global producer. The related paper has been published in Frontiers of Agricultural Science and Engineering (DOI: 10.15302/J-FASE-2025635).

Wenchao Li from Hebei Agricultural University and Lingling Hua from Beijing University of Agriculture et al. have developed an online monitoring system for NPS pollution in continuous cropping farmland based on a serial pipeline. The system, with diversion trenches, online flowmeters, and dynamic acquisition devices as the core, realizes real-time monitoring and automated sampling of farmland runoff through innovative design. Compared with traditional runoff pools, the design of diversion trenches and transmission pipelines in the new system significantly reduces the project scale, lowers construction costs and land occupation, and avoids interference with agricultural production activities.

A team of UC Riverside engineering scholars have discovered why a key solid-state battery ceramic material stays remarkably cool during operation — a breakthrough that could help make the next generation of lithium batteries  deliver higher energy density while reducing overheating and fire risks.

A groundbreaking approach to turning waste into wealth is set to take center stage in an upcoming international webinar.

Utah-based ARUP Laboratories developed an AI tool that excels at detecting parasites in stool samples. Working with University of Utah pathologists and university startup called Techcyte demonstrate the power of the tool, opening the way for potentially transforming how intestinal infections are diagnosed. 

The first analysis of recent extinctions across plants and animals finds that, contrary to previous studies, the rate at which many groups of organisms have gone extinct has declined over the last 100 years. The research also revealed that the patterns and causes of these past extinctions differed from current and future threats, making it problematic to extrapolate them into the future: While past extinctions were predominantly due to invasive species on islands, habitat destruction presents the greatest threat currently.
