An international research team reveals consistent growth in PFAS research by conducting bibliometric analysis of 1,281 publications from 2003 to 2023. The study, conducted using analytical tools like CiteSpace and VOSviewer, identifies the United States, China, and Sweden as the leading contributors. It provides a comprehensive overview of PFASs in drinking water, highlighting that their entry into water supplies is governed by surface runoff, soil leaching, and atmospheric deposition. While traditional analysis relies on liquid chromatography–tandem mass spectrometry, new portable sensors are emerging. Current removal strategies—such as activated carbon, ion-exchange, membranes, and advanced oxidation processes—involve significant cost-performance trade-offs. Key persistent challenges include monitoring short-chain and novel ether PFASs, managing concentrated waste, and establishing unified regulatory standards. This study aims to guide future research and policy to accelerate the achievement of PFAS-free drinking water.
Conventional studies on stem cell fates are primarily focused on transcription factors, with the limited consideration for 3D genome architecture. The cohesin complex dynamically restructures chromatin topology to precisely coordinate enhancer-promoter interactions, which offers novel insights into fate decisions of hematopoietic stem cells, embryonic stem cells, and neural stem cells. This mechanisms provide significant applications for regenerative medicine and cancer therapy. Prof. Zuping He’s team at Hainan Medical University has reviewed multidimensional regulatory networks of the complex in ‘The Functions and Mechanisms of the Cohesin Complex in Regulating the Fate Determinations of Stem Cells’.
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. The related paper had been published in Frontiers of Agricultural Science and Engineering (DOI: 10.15302/J-FASE-2024596).
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.
