Studies of hunter-gatherer locomotion inform a wide range of academic fields, from human behavioural ecology and hominin evolution to sports science and evolutionary health. Despite celebrated ethnographic examples of hunter-gatherer locomotor proficiency in running, climbing, swimming and diving, there has been limited systematic analysis of cross-cultural variation in hunter-gatherer locomotor versatility. We conducted a systematic cross-cultural analysis of hunter-gatherer locomotion, coding locomotor behaviour from over 900 ethnographic documents. Our results indicated that high levels of locomotor versatility are common among hunter-gatherers, and that proficiency of running, climbing, swimming and diving is found in societies across the geographical and ecological breadth of the sample. Each locomotor modality was found to be relevant not only to food acquisition but also in leisure, ritual and violent conflict. Our results also indicated the prevalence of both male and female engagement within each locomotor modality, with climbing being the only modality to possess a notable bias towards male engagement in a substantial proportion of societies. The widespread habituality and functional significance of diverse locomotor proficiency in hunter-gatherers suggests that locomotor versatility represents a dimension of human adaptive lability, playing a major role in the ability of hunter-gatherers to thrive in almost every global ecology.

Acute neuroinflammation, which is notably characterized by a significant elevation in pro-inflammatory cytokines and chemokines, often rapidly develops following a traumatic spinal cord injury and exacerbates damage in the lesion area. This study addresses the limitations inherent in strategies that regulate only a single or a few cytokines, which are often insufficient to counteract the progression of secondary injuries. We explore the use of polydopamine nanoparticles as a broad-spectrum immunomodulator, capable of capturing by adsorption a wide range of cytokines and thereby effectively suppressing neuroinflammation.

Most birds can navigate seamlessly between aerial and terrestrial environments. Whereas the forelimbs evolved into wings primarily for flight, the hindlimbs serve diverse functions such as walking, hopping and leaping, and jumping take-off for transitions into flight. These capabilities have inspired engineers to aim for similar multimodality in aerial robots, expanding their range of applications across diverse environments.

As pollinators, bees are key to maintaining the biodiversity of angiosperm plants, and for agriculture they provide a billion-dollar ecosystem service. But they also compete for resources (primarily nectar and pollen), especially the highly social bees that live in perennial colonies. So, how do they organize their daily temporal activities? Here, we present a versatile, low-cost device for the continuous, automatic recording and data analysis of the locomotor activity in the colony-entrance tube of highly eusocial bees.
