Chinese researchers have taken a fresh look at one of the biggest challenges in precision manufacturing: understanding and controlling the many different errors that affect the accuracy of machine tools. Their review, published in the International Journal of Extreme Manufacturing, explains why these errors are becoming increasingly complex to manage and how new technologies can help.

Iron fortified hemp biochar made from agricultural waste can significantly cut the amount of “forever chemicals” that move from contaminated soil into food crops, according to a new study on radishes grown in PFAS polluted soil.

N,N-diethyl-m-toluamide, better known as DEET, is one of the world’s most widely used insect repellents – and it is now turning up in rivers, lakes, groundwater and even drinking water around the globe, according to a new review by an international research team. The authors warn that while DEET helps protect millions of people from mosquito-borne diseases, its growing footprint in aquatic environments raises questions about long‑term ecological and health risks.

Researchers have unveiled a new catalyst made from renewable plant waste that could significantly accelerate clean hydrogen production. The innovative material, created by embedding nickel oxide and iron oxide nanoparticles into lignin-derived carbon fibers, boosts the efficiency and stability of the oxygen evolution reaction, a key step in water electrolysis.

Developing elite fruit cultivars typically requires long breeding cycles, especially in perennial woody species. 

Fungal endophthalmitis, a devastating intraocular infection, remains one of ophthalmology's greatest clinical challenges due to its rarity, delayed onset, and complex pathology.

Organoid research has rapidly advanced as a transformative platform for modeling development, disease, and regeneration, yet inconsistent reporting has hindered reproducibility and limited data integration across laboratories. The newly introduced Minimum Information about Organoid Research (MIOR) framework establishes a comprehensive, modular reporting system designed to address these challenges. MIOR defines clear requirements for project metadata, biological sources, organoid characterization, culture conditions, engineering strategies, and assay parameters. By distinguishing essential from recommended fields, the framework balances rigor with practical usability. MIOR aims to turn organoid datasets into reusable, comparable resources and strengthen the reliability and translational potential of organoid-based research.

Multi-element co-doping has become an effective approach to optimize thin-film quality and enhance device power conversion efficiency (PCE) in studies related to CZTSSe solar cells. However, most of co-doping studies have primarily concentrated on the isolated effects of individual doping elements on CZTSSe thin films, often neglecting the potential interactions between co-doping elements. This study investigates the interactions between Li and Ag in CZTSSe thin films, revealing the underlying mechanism by which Ag incorporation enhances the Li tolerance. These findings provide valuable insights and guidance for future studies on co-doping strategies.

The atomically precise [Au₁₃Ag₁₂(PPh₂Py)₁₀Cl₈]PF₆ supported on activated carbon (AC) were utilized as a catalyst for epoxide cycloaddition with CO₂. The reaction shows high efficiency and wide substrate tolerance. Mechanistic study reveals the that structural flexibility at the waist Ag-Cl bonds dominates the coordination of epoxide, and then the electrophilic attack of CO₂ and the cyclization enables the catalytic reaction. This study implies that the structural flexibility of the surface blocks might be an advantage of metal nanoclusters in catalysis.

Prolonged exposure to hot weather and direct sunlight can lead to heat exhaustion and skin irritation, which reduces the productivity of outdoor workers and increases health risks. This study has developed a polylactic acid/boron nitride nanosheet composite fabric by electrospinning. Being selectively modified for hydrophilicity, the fabric has combined passive radiative cooling, thermal conductivity and directional sweat wicking to improve thermal comfort in outdoor environments. Compared to conventional cotton fabrics, the composite fibric exhibits excellent solar reflectance (96%) and infrared heat emissivity (93%), along with high thermal conductivity (0.38 W·m^-1 K^-1). In outdoor experiments, the composite fabric lowers skin temperature by 2.0 °C under direct sunlight during the day and by 3.8 °C at night relative to bare skin. The composite fabric features a directional perspiration function and an impressive sweat evaporation rate of 1.67 g·h⁻¹, which can efficiently transport sweat and heat to the fiber membrane surface to keep the skin dry and cool. This work should advance human thermal management strategies for high-temperature outdoor environments.
