The study of memory is commonly associated with neuroscience, aging, education, and eyewitness testimony. Here we discuss how eating behavior is also heavily intertwined-and yet considerably understudied in its relation to memory processes. Both are influenced by similar neuroendocrine signals (e.g., leptin and ghrelin) and are dependent on hippocampal functions. While learning processes have long been implicated in influencing eating behavior, recent research has shown how memory of recent eating modulates future consumption. In humans, obesity is associated with impaired memory performance, and in rodents, dietary-induced obesity causes rapid decrements to memory. Lesions to the hippocampus disrupt memory but also induce obesity, highlighting a cyclic relationship between obesity and memory impairment. Enhancing memory of eating has been shown to reduce future eating and yet, little is known about what influences memory of eating or how memory of eating differs from memory for other behaviors. We discuss recent advancements in these areas and highlight fruitful research pursuits afforded by combining the study of memory with the study of eating behavior.

Hoverflies are essential to ecosystems, with adults serving as important pollinators and larvae preying on plant-feeding insects or recycling nutrients. Species like Sphaerophoria rueppellii are used in biocontrol programs to target aphid pests. To enhance these programs, markers can be used in a mark-release-recapture (MRR) method to track hoverfly feeding and oviposition sites.

Background: The integration of technology throughout daily life has become a pervasive environmental influence with wide-ranging implications, including on how we eat. Previous research demonstrates that simultaneously eating and watching television (TV) leads to increased food consumption. However, the effects of smartphone use are still uncertain as the limited existing research has yielded conflicting findings.

Forbs ("wildflowers") are important contributors to grassland biodiversity but are vulnerable to environmental changes. In a factorial experiment at 94 sites on 6 continents, we test the global generality of several broad predictions: (1) Forb cover and richness decline under nutrient enrichment, particularly nitrogen enrichment. (2) Forb cover and richness increase under herbivory by large mammals.

The Central African Republic, one of the world's most fragile nations with a critically human development index, is facing escalating rates of noncommunicable diseases, including oral diseases. This study aims to comprehensively assess the oral health status of schoolchildren in Bangui, the capital city. A cross-sectional epidemiological survey was conducted during November-December 2023 on 556 schoolchildren aged 5 to 13 years old, (41.

Elevated fasting insulin levels (FI), indicative of altered insulin secretion and sensitivity, may precede type 2 diabetes (T2D) and cardiovascular disease onset. In this study, we group FI-associated genetic variants based on their genetic and phenotypic similarities and identify seven clusters with distinct mechanisms contributing to elevated FI levels. Clusters fall into two types: "non-diabetogenic hyperinsulinemia," where clusters are not associated with increased T2D risk, and "diabetogenic hyperinsulinemia," where T2D associations are driven by body fat distribution, liver function, circulating lipids, or inflammation.
