The article estimates the value-based price of a blood test for Alzheimer's disease pathology, finding it would be $290-$1150 in primary care and $450-$1950 in specialty care, projecting substantial cost savings.

The study demonstrates that adopting more climate-friendly diets, which typically involve reduced animal-based food consumption and lower absolute micronutrient intakes, does not substantially increase the risk of micronutrient deficiencies for most nutrients. These findings underscore the importance of assessing both dietary intake and actual nutrient status when evaluating the nutritional consequences of sustainable eating patterns, supporting the potential health and environmental benefits of shifting toward climate-friendly diets.

Low-income citizens show the highest support for food labeling and educational campaigns, viewing them as effective and less intrusive, while taxation and checkout prompts are least accepted due to perceived invasiveness. Policy support is strongly influenced by perceived effectiveness, intrusiveness, and individuals’ existing behaviors, suggesting tailored approaches are needed to improve acceptance and impact.

The paper critically examines the assumption that access to electricity (SDG 7) inherently promotes gender equality (SDG 5). It finds that the gendered impacts of electricity access vary widely—sometimes empowering women, but other times reinforcing existing inequalities. To better understand these dynamics, the authors develop a new theoretical framework that merges: Gender Studies insights on gender as performative, intersectional, and shaped by power relations. Social Practice Theory, which explores how electricity gains meaning through its role in everyday practices. This framework is applied to case studies in rural Guatemala (patriarchal) and rural Colombia (matrilineal), revealing how cultural context shapes outcomes. The paper also introduces an 8-step methodology for applying this framework in practice. Ultimately, the study offers tools for designing context-sensitive energy policies that are more likely to advance gender equality.
