Populations consuming saline drinking water are at greater risk of high blood pressure and potentially other adverse health outcomes. We modelled data and used available datasets to identify countries of higher vulnerability to future saltwater intrusion associated with climate change in 2050 under Representative Concentration Pathways (RCP)4.5 and RCP8.5. We developed three vulnerability criteria to capture geographies with: (1) any coastal areas with projected inland saltwater intrusion of ≥ 1 km inland, (2) > 50% of the population in coastal secondary administrative areas with reliance on groundwater for drinking water, and 3) high national average sodium urinary excretion (i.e., > 3 g/day). We identified 41 nations across all continents (except Antarctica) with ≥ 1 km of inland saltwater intrusion by 2050. Seven low- and middle-income countries of higher vulnerability were all concentrated in South/Southeast Asia. Based on these initial findings, future research should study geological nuances at the local level in higher-risk areas and co-produce with local communities contextually appropriate solutions to secure equitable access to clean drinking water.

Most studies in astrobotany employ soil as the primary crop-growing medium, which is being researched and innovated. However, utilizing soil for planting in microgravity conditions may be impractical due to its weight, the issue of particles suspended in microgravity, and its propensity to harbor pathogenic microorganisms that pose health risks. Hence, soilless irrigation and fertigation systems such as fogponics possess a high potential for space farming. Fogponics is a promising variation of aeroponics, which involves the delivery of nutrient-rich water as a fine fog to plant roots. However, evaluating the strengths and weaknesses of fogponics compared to other soilless cultivation methods is essential. Additionally, optimizing fogponics systems for effective crop cultivation in microgravity environments is crucial. This study investigated the interaction of fogponics and artificial intelligence for crop cultivation in microgravity environments, aiming to replace soil-based methods, filling a significant research gap as the first comprehensive examination of this interplay in the literature. A comparative assessment of soilless fertigation and irrigation techniques to identify strengths and weaknesses was conducted, providing an overview through a literature review. This highlights key concepts, methodologies, and findings, emphasizing fogponics’ relevance in space exploration and identifying gaps in current understanding. Insights suggest that developing adaptive fogponics systems for microgravity faces challenges due to uncharacterized fog behavior and optimization complexities without gravity. Fogponics shows promise for sustainable space agriculture, yet it lags in technological integration compared with hydroponics and aeroponics. Future research should focus on microgravity fog behavior analysis, the development of an effective and optimized space mission-compatible fogponics system, and system improvements such as an electronic nose for an adaptive system fog chemical composition. This study recommends integrating advanced technologies like AI-driven closed-loop systems to advance fogponics applications in space farming.

ABSTRACTBackground Chronic pain and higher body weight frequently co-occur. This common comorbidity is thought to be mediated by the use of comfort eating as a strategy for managing both the physical and psychological pain and discomfort associated with flare-ups of chronic pain. Valid and reliable assessment tools are needed to inform the development of effective treatments.Aims This study aimed to assess the psychometric properties of a new brief measure of pain-induced comfort eating in chronic pain, the Pain-Induced Comfort Eating Scale (PICES).Methods A sample of 166 patients with chronic pain completed an online test battery including the PICES along with measures of chronic pain and pain-related symptoms, disordered eating, and related psychological factors.Results Results of exploratory factor analysis revealed a single-factor model for the four-item PICES. Further, the PICES demonstrated evidence of good internal consistency as well as convergent validity with demonstrated correlations with related measures. The results of this study also revealed that comfort eating in chronic pain appears to be related to psychological distress; the PICES correlated more strongly with measures assessing mood and psychological distress compared to interference/intensity of physical pain itself. Scores on the PICES also correlated strongly with measures of uncontrolled and emotional eating.Conclusions Overall, our results indicate that the PICES provides a valid and useful brief measure of comfort eating in chronic pain that might be useful to inform treatments targeting the comorbid disordered eating practices that can lead to higher body weights in patients with chronic pain.
