This study demonstrates that malaria mosquito mating swarms emerge from simple, minimally interactive behavioral rules driven primarily by environmental cues rather than complex social interactions, a finding validated through 3D flight tracking and agent-based modeling.
This study establishes the Differential Reinforcement of Low-Rate (DRL) task in cynomolgus macaques as a translationally relevant platform for screening antidepressant efficacy, demonstrating its ability to distinguish antidepressant-like effects across diverse drug classes while simultaneously identifying dose-limiting side effects like emesis that are not observable in rodent models.
This study reveals that zebrafish transition from light-seeking to dark-seeking behavior during ontogeny by shifting their reliance from spatio-temporal visual computations to ambient luminance detection, a strategy governed by parallel processing pathways that enable flexible, goal-oriented navigation.
A study of wild Guinea baboons found that despite the species' tolerant social system, variation in maternal care style does not significantly predict infant growth or survival, suggesting that factors like disease and predation play a more critical role in this high-capacity habitat.
This study reveals that loser effects, rather than winner effects, play a critical role in establishing social dominance hierarchies among females in a sex-changing fish species, thereby providing a behavioral mechanism that may drive the evolutionarily advantageous process of sexual transition.
This paper introduces a low-cost, low-power 3D imaging system that reveals honeybee swarm assembly as a two-phase process of rapid low-density clustering followed by slow contraction, while disassembly occurs significantly faster through strongly divergent flight.
This study demonstrates that recurrent hypoglycemia exacerbates cognitive impairment in type 2 diabetes by activating brain endothelial ZBP1-mediated PANoptosis through the AGE-RAGE signaling axis.
Chronic restraint stress during adolescence induces sex-dependent negative cognitive biases and reduces specific functional connectivity in female rats, but not males, suggesting distinct neurobiological mechanisms underlying the heightened vulnerability of females to stress-related depression.
This study demonstrates that in nonhuman primates, the temporal structure of respiration (such as inhalation onset and cycle length) is a more reliable predictor of visual detection performance than amplitude-based measures, highlighting the critical role of breathing rhythms in shaping moment-to-moment cognitive behavior.
This study demonstrates that an iterative machine learning approach, which predicts aversive valence from chemical structure and refines models with behavioral data from both honey bees and Drosophila, successfully identified and validated potent repellent odorants capable of protecting free-flying honey bees from pesticide exposure in the field.
By employing a closed-loop real-virtual interaction system with rummy-nose tetras, this study demonstrates that individual fish sustain coordinated group motion by selectively responding to a single, dynamically changing most influential neighbor rather than integrating information from multiple conspecifics.
This study reveals that poison frogs with divergent reproductive strategies cope with seasonal rainfall fluctuations primarily through behavioral flexibility in space and microhabitat use, while their hormonal profiles and chemical defenses remain largely decoupled from these environmental changes.
This study demonstrates that rats in the midsession reversal task utilize a mixed strategy integrating local reinforcement cues with global temporal information, as evidenced by their ability to adjust switching behavior based on manipulated intertrial intervals rather than fixed trial numbers.
This study reveals that sleep deprivation impairs prefrontal information processing by upregulating BDNF-TrkB signaling, which downregulates the chloride exporter KCC2 to disrupt chloride homeostasis and weaken GABAergic inhibition, a mechanism distinct from but additive to allopregnanolone-mediated deficits.
This study demonstrates that mutations in individual members of the TALE and Hox transcription factor families in adult zebrafish cause both shared stress-related behavioral abnormalities and distinct, mutation-specific deficits in coping, social interaction, learning, and locomotion, revealing how genetic variation within these families differentially contributes to mental health disorder vulnerabilities.
Through direct video monitoring in the wild, this study reveals that subordinate black-striped mice (*Apodemus agrarius*) avoid agonistic competition with dominant yellow-necked mice (*Apodemus flavicollis*) for a novel food source by switching their foraging activity from nocturnal to diurnal, thereby achieving temporal niche segregation and safe resource access.
This study demonstrates that while low adiponectin levels correlate with poorer mental health in non-obese women with PCOS, adiponectin deficiency alone does not exacerbate anxiety-like behaviors in a lean PCOS-like mouse model, highlighting the complex interplay between adipokines, androgens, and mental health in the syndrome.
This study demonstrates that defensive responses to predators in mice are not obligatory or uniform but are instead flexibly shaped by environmental context, task demands, and individual variability, challenging the assumption that innate fear behaviors are automatically triggered by threat.
This study demonstrates that withdrawing young male Wistar rats from a two-week high-sugar/high-fat diet triggers rapid metabolic disturbances, increased systemic and neuroinflammation, hippocampal oxidative stress, and heightened anxiety-like behaviors.
