Ensuring food security requires innovative, sustainable pest management solutions. The Solar Insecticidal Lamp Internet of Things (SIL-IoT) represents such an advancement, yet its reliability in harsh, variable outdoor environments is compromised by frequent component and sensor faults, threatening effective pest control and data integrity. This paper presents a comprehensive survey on fault detection (FD) for SIL-IoT systems, systematically analyzing their unique challenges, including electromagnetic interference, resource constraints, data scarcity, and network instability. To address these challenges, we investigate countermeasures, including blind source separation for signal decomposition under interference, lightweight model techniques for edge deployment, and transfer/self-supervised learning for low-cost fault modeling across diverse agricultural scenarios. A dedicated case study, utilizing sensor fault data of SIL-IoT, demonstrates the efficacy of these approaches: an empirical mode decomposition-enhanced model achieved 97.89% accuracy, while a depthwise separable-based convolutional neural network variant reduced computational cost by 88.7% with comparable performance. This survey not only synthesizes the state of the art but also provides a structured framework and actionable insights for developing robust, efficient, and scalable FD solutions, thereby enhancing the operational reliability and sustainability of SIL-IoT systems.

This comprehensive review compiles current knowledge about the connection between plastic waste and the selection and transmission of antibiotic resistance genes (ARGs) in aquatic ecosystems, which can result in ARG contamination of fishery products—a significant source of microplastic (MP) introduction into the food chain. Plastic debris in aquatic environments is covered by a biofilm (the plastisphere) in which antibiotic-resistant bacteria (ARB) are selected and horizontal gene transfer (HGT) of ARGs is facilitated. The types of plastic waste considered in this study for their role in ARG enrichment are mainly microplastics (MPs), and also nanoplastics (NPs) and macroplastics. Studies regarding freshwaters, seawaters, aquaculture farms, and ARG accumulation favored by MPs in aquatic animals were considered. Most studies focused on the identification of the microbiota and its correlation with ARGs in plastic biofilms, while a few evaluated the effect of MPs on ARG selection in aquatic animals. A higher abundance of ARGs in the plastisphere than in the surrounding water or natural solid substrates such as sand, rocks, and wood was repeatedly reported. Studies regarding aquatic animals showed that MPs alone, or in association with antibiotics, favored the increase in ARGs in exposed organisms, with the risk of their introduction into the food chain. Therefore, reducing plastic pollution in water bodies and aquaculture waters could mitigate the ARG threat. Further investigations focused on ARG selection in aquatic animals should be conducted to better assess health risks and increase awareness of this ARG transmission route, enabling the adoption of appropriate countermeasures.

The discovery and clinical deployment of antibiotics marked a paradigm shift in combating bacterial infections, profoundly benefiting human medicine, veterinary health, and agricultural productivity. However, pervasive overuse in both the clinical and livestock sectors has precipitated an alarming acceleration of antimicrobial resistance, now recognized as a critical global health threat. Compounding this crisis, livestock-associated resistant pathogens persistently colonize the food production continuum, enabling zoonotic transmission through animal-derived products and endangering public health, food safety, and human survival. This review delineates current insights into bacterial resistance mechanisms and evaluates innovative countermeasures, aiming to inform future antimicrobial development and resistance containment strategies.

Cultivated land (CL) is essential for human survival, as its coordinated utilization plays a crucial role in both food production and ecological protection. In this study, we focus on Aksu, a typical oasis in arid areas of Xinjiang, to explore how to improve the eco-efficiency of cultivated land utilization (ECLU) from the perspective of carbon emissions under different ownership structures. The goal is to provide policy support for the sustainable intensification of CL in Aksu. The super-efficiency slack-based measure (Super-SBM) model was used to calculate the ECLU, while the carbon emissions coefficient method was employed to estimate cultivated land carbon emissions (CLCE). Additionally, the random forest regression (RFR) model was utilized to analyze differences in CLCE between collective and state-owned cultivated lands. Finally, a Geo-detector analysis was conducted to identify driving factors of CLCE. The findings indicate that the overall ECLU values in Aksu initially increased and subsequently decreased over time. During the study period, Kalpin showed the highest ECLU, followed by Wensu and Wushi. The total CLCE in Aksu demonstrated an initial increase followed by a decrease, but the overall trend was growth, from 3.7 t in 2008 to 5.63 t in 2019, on average. It was observed that carbon emissions from state-owned cultivated land were greater than those from collective cultivated land, and carbon emissions from non-food crops were higher than those from food crops. Furthermore, spatial heterogeneity was evident in the CLCE. The single factor detection results showed that the Local_GDP (q = 0.763, representing the explanatory power of the Local_GDP on cultivated land carbon emissions) was identified as the main driver of CLCE in Aksu. The interactive detection results indicated that the Local_GDP and Farmer income (0.839) had stronger effects on CLCE in Aksu than any other two factors. It was also found that ownership of CL directly affects CLCE and indirectly affects the ECLU. In conclusion, it is necessary to formulate corresponding countermeasures for improving the ECLU involving government intervention, as well as cooperation with farmers and other stakeholders, to address these issues effectively within Aksu’s agricultural sector.

Background: Occupational accidents, injuries, and illnesses are serious problems for organizations. Workplace sleepiness is a major issue that affects occupational safety and productivity. Workplace sleepiness is influenced by sleep, diet, and blood glucose levels, but the causal relationship is unclear. This scoping review aimed to investigate the factors affecting work productivity, with a particular focus on the impact of sleepiness caused by food intake and blood glucose level on productivity. Methods: PubMed, and Web of Science were used to search terms, such as “workplace,” “sleepiness or postprandial hypoglycemia,” “productivity,” and “measurement.” The following studies were included: (1) those with working hours evaluations; (2) that excluded patients with diabetes, heart diseases, or other diseases; (3) that excluded patients with mental illness; (4) that did not limit the evaluation of sleepiness at work to sleep only; (5) with publications after 2014; and (6) that were research articles. Results: The search yielded 521 articles. Nine papers met the inclusion criteria. Six studies assessed blood glucose levels, six assessed sleepiness, and one simultaneously assessed blood glucose and sleepiness. The Karolinska Sleepiness Scale (KSS) is the most frequently used sleep measure. Most studies have assessed the effects of controlled diets. Although some studies have used continuous glucometers, their evaluation of blood glucose levels has been limited. The extracted literature also included mild exercise and control of environmental illumination as a countermeasure against sleepiness. Conclusions: Although few studies have analyzed the causes and countermeasures of sleepiness in the workplace, sleepiness affects work productivity, diet affects sleepiness, and several methods for suppressing sleepiness have been researched. However, a few studies have directly evaluated the effects of blood glucose fluctuations and sleepiness on work productivity. These results suggest that further research into the relationship between sleepiness at work and related biological signals and blood glucose fluctuations will be important in understanding the causes, as it will form the basis for measures to improve work productivity.

Aflatoxin B₁ (AFB₁), the most potent and widespread mycotoxin produced by Aspergillus flavus and Aspergillus parasiticus, poses a significant global threat to food safety and human health, with chronic exposure strongly linked to hepatocellular carcinoma (HCC). While physical and chemical detoxification approaches exist, their limitations have led to an increased interest in biological strategies, particularly probiotic interventions. In this review, we synthesize current in vivo and clinical evidence on the ability of probiotic lactic acid bacteria—including Lactobacillus casei Shirota, Lactobacillus rhamnosus GG, Lactobacillus rhamnosus LC705, Lactococcus lactis, and selected Bifidobacterium species—to reduce AFB₁ absorption and toxicity. We summarize mechanistic insights into cell wall adsorption, gut microbiota modulation, intestinal barrier protection, and antioxidant enhancement. Clinical trials have shown reductions in AFB₁ biomarkers following probiotic supplementation, supporting their translational potential for human health. However, clinical evidence remains limited by small sample sizes, short intervention periods, and variability in endpoints. Collectively, this review consolidates mechanistic, preclinical, and clinical findings to position probiotic lactic acid bacteria as promising biological countermeasures against AFB1-induced hepatocellular carcinoma.

This study evaluated a novel methodology for assessing food safety vulnerabilities in shopping malls by integrating Hazard Analysis and Critical Control Points (HACCP), Threat Assessment and Critical Points (TACCP), and Failure Mode and Effects Analysis (FMEA). Inspections were conducted in nine shopping centers across Poland, the Czech Republic, Slovakia, and Spain to identify the risk of intentional/unintentional contamination with chemical, biological, radiological, and nuclear agents. The assessment considered key operational areas, including food delivery, transportation, staff security, back-office access, product handling, and inspection protocols. Risk levels were quantified using FMEA parameters. The findings revealed an overall high to average risk score with the most critical vulnerabilities linked to back-office access, unauthorized personnel entry, and susceptibility to fraudulent inspections. Observations also highlighted infrastructural shortcomings, insufficient monitoring, and procedural gaps that could facilitate contamination. The proposed methodology offers a structured, quantitative framework for identifying and prioritizing food safety hazards in public environments. Implementing targeted countermeasures—such as enhanced surveillance, strict access control, staff training, and dedicated food handling protocols—can substantially reduce risks, thereby strengthening public health protection and operational resilience. This approach may serve as a promising framework for integrating food defense and safety assessments for food defense in high-density commercial facilities. Full article

Despite global initiatives to combat Illegal, Unreported, and Unregulated (IUU) fishing, such activities continue unabated. As a response, states are encouraged to join the Food and Agriculture Organization of the United Nations Port State Measures Agreement (PSMA) as a countermeasure. Despite these efforts, it is suspected that many IUU fishing activities involve non-party or unknown vessels that evade international sanctions. This study aims to propose technical and institutional improvement measures in light of these challenges. First, using available IUU vessel lists, we conducted independent-sample comparisons and paired-sample comparisons to analyze the characteristics of IUU vessels. As key solutions, we propose the formation of a global collaborative body to facilitate an integrated information chain, the implementation of advanced technologies for systematic operations, strategies to encourage PSMA accession by non-parties, market investigations, and enhanced national inspection and organizational capabilities. Furthermore, this study seeks to strengthen global deterrence of IUU fishing activities by proposing a phased international cooperation framework to enhance the feasibility of integrating the PSMA, Global Record (GR), Global Information Exchange System (GIES), and Regional Fisheries Management Organization (RFMO) systems. These strategies are expected to contribute positively to the transparent governance, sustainable management of fishery resources, and safety officers and vessels. Full article

(1) Background: Over the years, technology and space missions have advanced, although the development of potential functional food and food supplements must be improved for maintaining astronauts’ health and helping them overcome space-specific challenges during long missions. (2) Scope and approach: Using a review approach, this study aimed to investigate the potential of functional food to counteract radiation and microgravity spaceflight-related health problems. (3) Results: Microgravity and space radiation affect the body’s biochemical processes and increase levels of reactive oxygen species, which may lead to health problems, including musculoskeletal deconditioning, cardiovascular degeneration, disruptions in gastrointestinal health, ocular problems, alterations to the immune system, and hormonal imbalances, among others. In addition to medical care, functional food plays a key role as a countermeasure against space-induced physiological issues. Previous research showed that functional food rich in flavonoids, omega-3 fatty acids, vitamins, minerals, antioxidant compounds, proteins, probiotics, or prebiotics strengthens the immune system and reduces risks associated with long spaceflights, such as bone density loss, muscle atrophy, oxidative stress, and other health alterations. (4) Conclusions: Despite the fundamental role of functional food in spaceflights, the main challenges remain in preserving and packaging these foods to ensure their safety on long space missions. Future innovations include 3D food printing, space algae cultivation, and novel preservation technologies. Full article

As the leading grain-producing region in China, Heilongjiang Province is crucial to the country’s food security. Thus, determining Heilongjiang’s agricultural carbon emissions status and trend projections provides a baseline for supporting low-carbon emission reduction in this sector. This study analyzes carbon emissions from crop farming and farmland soil in Heilongjiang from 2003 to 2022, focusing on two carbon sources: agricultural land use and soil. BP neural network model, emission factor coefficient approach, Tapio decoupling framework, and LMDI model are used. These findings show that Heilongjiang’s planting industry carbon emissions initially increased and then decreased, with chemical fertilizers and rice being the main sources. Harbin, Qiqihar, Jiamusi, and Suihua contribute significantly to soil carbon emissions from farming. In “weak decoupling-expanding negative decoupling-strong decoupling,” economic levels drive carbon emissions, while production efficiency is the key countermeasure. Qiqihar will not peak between 2023 and 2030, while the other 12 Heilongjiang cities will. Therefore, these emission-reduction proposals are presented: Restructuring (increasing drought-resistant and cold-climate low-carbon crops), optimizing fertilization (soil testing and organic fertilizers), and improving resource utilization can help Heilongjiang Province achieve “food security, ecological preservation, and low-carbon development” in its agricultural practices.

In recent years, with increasing global warming, extreme weather such as high temperatures and droughts has occurred more frequently, with serious impacts on grain production and farmers’ livelihoods. High temperatures and drought can lead to a range of production problems such as water shortages, increased irrigation costs, reduced land fertility, and reductions in grain yields. Ultimately, these problems can inhibit farmers’ willingness to grow grain and threaten regional food security. The government usually takes appropriate assistance measures to compensate for the loss of grain farmers, so as to stimulate the farmers’ incentive to grow grain. Therefore, the influence mechanism of government assistance on farmers’ willingness to grow grain in the context of extreme weather is an issue worth exploring. From the perspective of grain farmers, this paper takes the grain farmers in Jiangxi Province affected by high temperatures and drought in 2022 as the research sample and empirically analyzes the influence mechanism of government assistance on farmers’ willingness to grow grain. In addition, this paper also discusses the heterogeneity of the impact of government assistance on the planting willingness of farmers with different agricultural income ratios and literacy levels. The Ordered Logistic model and mediation effect model were applied in this study. The results of the study show that government assistance can effectively incentivize farmers’ willingness to grow grain, and risk preference has a mediating effect in the process. In addition, government assistance has a stronger incentive effect on the planting willingness of farmers with a high ratio of agricultural income and a high level of literacy. Finally, the paper puts forward corresponding countermeasure suggestions based on the conclusions to help the government formulate more complete risk response policies and establish a more effective risk prevention mechanism. This paper provides a theoretical reference for achieving sustainable development of grain production in the context of extreme weather, which helps to improve the resilience and sustainability of grain production.

Given the constraints of limited cultivated land resources, ensuring and enhancing crop productivity are crucial for food security. This study takes Chengdu as a case study. Using the cultivated land productivity (CLP) evaluation model, we calculated the cultivated land productivity index (CLPI) and analyzed its spatial distribution characteristics. The Geographical Detector model was employed to identify the main factors influencing CLP, and corresponding countermeasures and measures were proposed based on the limiting degrees of these factors. The findings reveal that Chengdu’s CLP index ranges from 1231 to 3053. Global spatial autocorrelation analysis indicates a spatial agglomeration pattern in Chengdu’s overall crop productivity distribution. The local spatial autocorrelation analysis demonstrates that township (street)-level crop productivity in Chengdu is primarily characterized by “high–high”, “low–low”, and “low–high” clusters. Key factors influencing the spatial differentiation of CLP in Chengdu include the agronomic management level, soil bulk density, irrigation guarantee rate, soil body configuration, field slope, and farmland flood control standard. Interaction detection shows that there are both double-factor and nonlinear enhancements among the factors. Specifically, the interaction between soil bulk density and the agronomic management level among other factors have the most explanatory power for the spatial differentiation of CLP. The CLP in Chengdu is highly restricted by its technical level, with the agronomic management level severely limiting CLP by more than 50%. These research results provide a theoretical reference for regional high-standard farmland construction and the protection and utilization of cultivated land resources. Full article

Promoting the sustainable development of agriculture is the basis of reducing the poverty rate, ensuring food security, and promoting common prosperity. In order to explore the impact of industrial capital and commercial capital on the sustainable development of agriculture, this paper starts from the perspective of agriculture and conducts empirical tests based on the panel data of 30 provinces in China (except Tibet) from 2013 to 2022, using the fixed-effect model and spatial spillover effect model. The results included the following: (1) industrial capital and commercial capital can significantly promote the sustainable development of agriculture, and this conclusion was still valid after endogenous test and robustness test; (2) a heterogeneity test showed that industrial capital and commercial capital has a stronger role in promoting the sustainable development of agriculture in non-major grain producing areas, areas with high marketization level and central and western regions; (3) the test of the transmission mechanism showed that industrial capital and commercial capital can promote the sustainable development of agriculture by optimizing agricultural production conditions, improving rural environment and promoting farmers’ poverty reduction and common prosperity; (4) further research showed that industrial and commercial capital has a positive spillover effect on the sustainable development of agriculture in neighboring areas while promoting the sustainable development of agriculture in this region. Based on the above conclusions, this paper puts forward some countermeasures and suggestions, such as improving rural infrastructure construction, strengthening efforts to guide industrial and commercial capital to the countryside, and paying attention to the differentiation of industrial and commercial capital investment development.

Soybean leaves, by-products of soybeans, are functional food supplements for overall health, displaying nutritional superiority and various functionalities; they are widely used for both consumption and as functional materials. This study analyzed the physiological activity (efficacy) of 47 soybean leaves harvested in 2019 and 2020. Differences based on cultivation year (2 years), seed coat color (three varieties), and the interaction of soybean cultivation year × seed coat color were determined using analysis of variance (ANOVA). DPPH radical scavenging activity varied with seed coat color, while uncoupling protein-1 (UCP-1) and nitric oxide (NO) exhibited significant differences by cultivation year. Items that displayed greater increases in 2020 than in 2019 among the six measures of physiological activity (efficacy) were estrogen receptor alpha, UCP-1, and NO production inhibitory activity, whereas ABTS and DPPH radical scavenging activities as well as estrogen activity declined. ANOVA confirmed significant differences in DPPH radical scavenging activity according to seed coat color as well as in UCP-1 and NO production inhibitory activity by cultivation year. Annual comparisons in the correlations of efficacy with ABTS and DPPH radical scavenging activities exhibited strong correlations at 2 years, despite climatic variation, thus potentially being classifiable as analysis items with high cultivation stability. However, other efficacies displayed vast differences in correlation between years. Climate change may affect the added value of agricultural products by reducing the production of by-product soybean leaves and changing their bioactive properties, so various countermeasures are needed. This annual variation may largely be attributed to climatic variations owing to open field cultivation. Geomjeong Kong-5 (black color), B16 Neoljeokseoritae (black color), Sorok Kong (yellow color), and Gangwonyanggu-1994-3709 (green–black color) were selected as superior soybean leaf sources with minimal annual variation and high stability against cultivation environments. Further research is needed to ensure that the leaves of the soybean can be used as a sustainable resource for the agricultural industry. The data from this study can be used as a basis for breeding and cultivating soybean leaves while maintaining high efficacy, regardless of the instability of the growing environment due to climatic variations.

Currently, there are no U.S. Food and Drug Administration (FDA)-approved medical countermeasures (MCMs) for radiation combined injury (RCI), partially due to limited understanding of its mechanisms. Our previous research suggests that endothelial dysfunction may contribute to a poor prognosis of RCI. In this study, we demonstrated an increased risk of mortality, body weight loss, and delayed skin wound healing in RCI mice compared to mice with skin wounds alone or radiation injury (RI) 30 days post-insult. Furthermore, we evaluated biomarkers of endothelial dysfunction, inflammation, and impaired wound healing in mice at early time points after RCI. Mice were exposed to 9.0 Gy total-body irradiation (TBI) followed by skin wound. Samples were collected on days 3, 7, and 14 post-TBI. Endothelial dysfunction markers were measured by ELISA, and skin wound healing was assessed histologically. Our results show that endothelial damage and inflammation are more severe and persistent in the RCI compared to the wound-alone group. Additionally, RCI impairs granulation tissue formation, reduces myofibroblast presence, and delays collagen deposition, correlating with more severe endothelial damage. TGF signaling may play a key role in this impaired healing. These findings suggest that targeting the endothelial dysfunction and TGF-β pathways may provide potential therapeutic strategies for improving delayed wound healing in RCI, which could subsequently influence outcomes such as survival after RCI.
