Collective memory can generally be defined as an account of the past that is shared by members of a group and is part of their identity project. In this paper, we attempt to discuss collective memory in terms of narrative, schema, and habit, three constructs that reflect an underlying assumption that humans are "cognitive misers" who gravitate toward ways to handle large amounts of information in efficient ways. Narrative makes it possible to grasp together a series of events into a meaningful whole, and collective memory emerges when members of a group share the same narrative tools. Schemata in the form of "narrative templates" are posited underlying codes that provide insight into patterns of narratives in collective memory. Lastly, habit is what drives much of human behavior: it allows us to perform a behavior unconsciously and automatically upon mere exposure to a context cue, which in turn allows for increased ease and efficiency in everything we do. Together, narrative, schema and habit provide insight into the building blocks of collective memory and why it can be so notoriously resistant to change. While our account may raise more questions than answers, we believe that this could be a fruitful and novel approach to the study of collective memory and hope it can contribute to both theoretical discussion and practical efforts to address one of today's most vexing issues.

Extending single-cell analysis to intact tissues while maintaining organ-scale spatial information poses a major challenge due to unequal chemical processing of densely packed cells. Here we introduce Continuous Redispersion of Volumetric Equilibrium (CuRVE) in nanoporous matrices, a framework to address this challenge. CuRVE ensures uniform processing of all cells in organ-scale tissues by perpetually maintaining dynamic equilibrium of the tissue's gradually shifting chemical environment.

Introduction: Functional beverages are increasingly popular but it is important to validate their purported effects through research. The aim of the current study was to investigate the effects of a new functional energy shot on cognitive performance and mood states in healthy adults, with a focus on measuring mental energy enhancement and attenuation of negative effects associated with extended performance of mentally demanding tasks.
Methods: This study was a randomized, double-blind, placebo-controlled, crossover trial.

Background: Movement behaviors, including physical activity (PA), sedentary behavior (SB), and sleep, are fundamental to early childhood development. These behaviors interact dynamically within a 24-hour period, creating a complex balance that influences not only physical health but also cognitive and emotional well-being in young children. While the physical health benefits of movement behaviors are well-documented, systematic evaluations of how interventions targeting these behaviors affect cognitive development in preschool-aged children remain limited.

The collective detrimental impact of aged naive lymphocytes and thymus atrophy on the aging of the immune system can be mitigated by exercise. Hence, this research aims to explore the effects of three methods of water-based exercises on immune system aging and thymus atrophy in elderly rats. Thirty-two 24-month-old rats, with an average weight of 320 ± 5 g, were randomly allocated into four groups of endurance training (n = 8), resistance training (n = 8), combined training (n = 8), and control (n = 8).

Background: Laji-He is a traditional rice-based snack from the Beibu Gulf region in southern China. In the Beibu Gulf region, "Laji-He" (literally "garbage He") signifies the removal of toxins from the body, making it a truly "green" food. Laji-He holds essential cultural and medicinal value, incorporating various medicinal plants into its preparation.
