This report covers a novel 3D-printed Luneburg lens built with diamond crystal lattices published in Engineering. Unlike conventional cubic lattice lenses, it features 34% packing density for lighter weight, stable permittivity across incident angles, and full six polarization states via a custom broadband feeding system. Tested across the full X-band, the lens delivers wide-angle scanning, lower sidelobes and consistent gain for satellite communications and integrated sensing applications.

Industrial large language models often spit out false technical answers due to limited domain knowledge. A new study in Engineering builds a complete RAG system tailored for manufacturing sectors. It uses a BERT filter to sort industrial questions, GTE-DPR for precise knowledge retrieval, and two mainstream open LLMs to generate reliable technical replies. Tests prove each module cuts AI hallucinations and boosts answer accuracy, offering a practical solution for smart factory knowledge queries.

Published in Engineering, this report covers a Yangzhou University study repurposing FDA-approved anticancer drug 5-FU as an adjuvant to boost fosfomycin against hard-to-treat MRSA. The combination disrupts bacterial pyrimidine metabolism, triggering membrane damage and lethal oxidative stress. In vitro tests prove its anti-biofilm activity, while two animal infection models verify its safe, potent in vivo efficacy, offering a feasible strategy to revive old antibiotics against resistant pathogens.

This report features a multicenter One Health study published in Engineering, tracking apramycin-resistant Escherichia coli (AREC) across livestock chains and human populations in three Chinese cities. The transferable aac(3)-IV gene on IncHI2/IncHI2A plasmids drives cross-host resistance spread. Growing veterinary apramycin consumption lifts resistance prevalence, reminding authorities to prudently evaluate its potential human clinical application.

Published in Engineering, this report covers a tomato greenhouse trial from China Agricultural University. Researchers tested three irrigation wetting modes and used multiomics to reveal how reduced soil moisture fluctuations lift yield, vitamin C and lycopene while cutting irrigation water by 30%–35%. It explains the microbial and molecular regulatory mechanisms and offers a low-cost irrigation strategy for water-limited farmland.

Published in Engineering, this meta-analysis covering 154 papers systematically compares transgenesis (TG) and genome editing (GE) for animal trait improvement. GE delivers larger, wider-ranging gains in growth and disease resistance yet shows taxon-specific effects. Trait enhancements weaken with animal age and in F1 offspring. The findings offer evidence for lab technique refinement and agricultural biotechnology policy-making.

This report covers a China Agricultural University study published in Engineering, which builds a BDS-IMU aided multimodal feature framework for 3D farm obstacle detection. The system cuts training sample reliance by 30%–40%, hits an overall 96.01% F₁ score and 16.56 FPS. It maintains reliable perception for unseen zero-sample agricultural obstacles, effectively easing heavy data annotation burdens and balancing detection accuracy, real-time performance and data efficiency for farm machinery autonomous navigation.

Worried about hidden meat spoilage risks in cold chains? This new study in Engineering develops a microwave sensor paired with machine learning to spot ammonia, a key rot marker, without damaging meat samples. It fixes reading errors caused by shifting temperature and humidity, cutting detection error to only 0.06 ppm and boosting accuracy by 31.11%. The wireless device works up to 12 meters away, offering a practical tool for real-time fresh meat quality tracking across storage and transport.

Want a non-destructive way to map fruit internal quality? Researchers built a fully wavelength-tunable SFDI imaging system covering 450–1040 nm. This modular device captures wide-field, depth-resolved optical properties of peaches, apples and pears without mechanical scanning. It accurately predicts peach firmness and reveals uneven pigment and water distribution inside fruit flesh, offering a precise new optical tool for agricultural fruit quality inspection.

A research team has developed a visible-light photocatalyst that nearly doubled hydrogen production by decorating cadmium sulfide (CdS) nanoparticles with carbon quantum dots (CQDs) derived from cellulose.
