The negative impact of juvenile undernourishment on adult behavior has been well reported for vertebrates, but relatively little is known about invertebrates. In honeybees, nutrition has long been known to affect task performance and timing of behavioral transitions. Whether and how a dietary restriction during larval development affects the task performance of adult honeybees is largely unknown. We raised honeybees , varying the amount of a standardized diet (150 µl, 160 µl, 180 µl in total). Emerging adults were marked and inserted into established colonies. Behavioral performance of nurse bees and foragers was investigated and physiological factors known to be involved in the regulation of social organization were quantified. Surprisingly, adult honeybees raised under different feeding regimes did not differ in any of the behaviors observed. No differences were observed in physiological parameters apart from weight. Honeybees were lighter when undernourished (150 µl), while they were heavier under the overfed treatment (180 µl) compared to the control group raised under a normal diet (160 µl). These data suggest that dietary restrictions during larval development do not affect task performance or physiology in this social insect despite producing clear effects on adult weight. We speculate that possible effects of larval undernourishment might be compensated during the early period of adult life.

Almost half of pregnant women globally are currently estimated to be overweight or obese. Rates of childhood obesity are also on the rise, in part because of increased consumption of dietary saturated fats. However, the long-term effect of peri- and postnatal high fat (HF) feeding on cognitive function and neuronal expression has not yet been investigated.

Background: The separation of structural isomers is always a challenging task for liquid chromatography because of their similar physicochemical property. Research has found that materials with regular microporous structures exhibit excellent isomer separation performance. However, as the most easily available chromatographic material, silica stationary phases with regular and small mesopore structure have not yet been prepared, and it remains to be confirmed whether narrow pores in silica materials have the enhancing effect on shape selectivity in the separation of structural isomers.

During Pavlovian conditioning, Sign-Tracker (ST), Goal-Tracker (GT), and Intermediate (IN) phenotypes emerge, as characterized by the degree to which an individual attributes incentive salience to reward-associated cues. These operationally defined phenotypes differ in other respects: In human studies, STs tend to favor bottom-up attention, while GTs tend to favor top-down attention. There is some limited evidence that rats exhibit similar patterns during Pavlovian conditioning.

Cyclists frequently experience task failure, an abrupt inability to maintain high-intensity effort, pushing both physiological and psychological boundaries. Although the physiological underpinnings of task failure are well-documented, the associated subjective and perceptual experiences remain underexplored. To address this gap, we surveyed 2,818 licensed cyclists, gathering extensive data on the subjective aspects of reaching the point of exhaustion.

The diagnosis of brain tumors is pivotal for effective treatment, with MRI serving as a commonly used non-invasive diagnostic modality in clinical practices. Fundamentally, brain tumor diagnosis is a type of pattern recognition task that requires the integration of information from multi-modal MRI images. However, existing fusion strategies are hindered by the scarcity of multi-modal imaging samples.
