This scoping review aimed to identify current evidence and gaps in the field of long-term space nutrition. Specifically, the review targeted critical nutritional needs during long-term manned missions in outer space in addition to the essential components of a sustainable space nutrition system for meeting these needs. The search phrase “space food and the survival of astronauts in long-term missions” was used to collect the initial 5432 articles from seven Chinese and seven English databases. From these articles, two independent reviewers screened titles and abstracts to identify 218 articles for full-text reviews based on three themes and 18 keyword combinations as eligibility criteria. The results suggest that it is possible to address short-term adverse environmental factors and nutritional deficiencies by adopting effective dietary measures, selecting the right types of foods and supplements, and engaging in specific sustainable food production and eating practices. However, to support self-sufficiency during long-term space exploration, the most optimal and sustainable space nutrition systems are likely to be supported primarily by fresh food production, natural unprocessed foods as diets, nutrient recycling of food scraps and cultivation systems, and the establishment of closed-loop biospheres or landscape-based space habitats as long-term life support systems.

Traffic noise is a significant risk factor for adverse health outcomes. Despite burgeoning interest in reducing the harmful health effects of traffic noise, research on the influence of physical and psychoacoustic attributes has been sparse. Consequently, this study examines the impacts of various acoustic attributes on mitigating stress response to traffic noise using dependent variables derived from electrodermal activity. The results indicate that: (a) mixing water sound (noise) at a low signal-to-noise ratio effectively mitigated stress response to traffic noise (signal), whereas mixing white noise with high fractal complexity (noise) significantly induced stress; and (b) sound pressure and acoustic sharpness significantly reduced stress response to traffic noise. Conversely, attributes such as high fractal complexity, moderate and high signal-to-noise ratios, acoustic loudness, and mean frequency significantly increased stress. This research offers a viable blueprint for creating evidence-based noise mitigation strategies that focus on intervention sound attributes.

Lack of consensus and funding led to a focus on building retrofits after storm surge flooding and collective inaction for undertaking cross-jurisdictional adaptation pathways planning. Using Seabrook, TX, United States, as a test case, this paper demonstrates the feasibility of using design games (participatory community visioning and design processes) to develop consensus-based, performance-driven, form-based codes from an adaptive landscape framework to facilitate emergency evacuation during storm surge flooding. The framework provides bottom-up mechanisms to enhance the sizes, coverages, quantities, and connectivity of multi-scalar engineered structural and nature-based solutions as a complex adaptive system to increase evacuation time and decrease flood-prone population.
