Article Synopsis
  • The study involved 431 children aged 5 to 10, examining their choices about censoring movies that depicted harmful behaviors.
  • Children tended to censor intentional harms more than accidental ones and showed a preference for restricting content based on the viewer's age.
  • The research highlights children's ability to make thoughtful decisions about censorship and suggests that they are motivated to prevent both sadness and the encouragement of harmful actions through media.

Article Synopsis
  • The study explored how children (ages 4-10) understand social hierarchies by observing an agent's choices between different groups, concluding that kids can identify patterns indicating which groups are preferred or dominant.
  • In experiments, children tracked the agent's selections to infer that certain groups were leaders and helpers based on the frequency of positive selection, demonstrating their ability to deduce social status.
  • The findings indicate that children learn about social structures through repeated observations of group-based choices, becoming capable of reasoning about the social standing of groups in their environment.

Wealth, power, and status are distributed unevenly across social groups. A surge of recent research reveals that people being recognizing, representing, and reasoning about group-based patterns of inequity during the first years of life. We first synthesize recent research on what children learn about group-based social hierarchies as well as how this learning occurs.

The real-time monitoring of neurochemical release plays a critical role in understanding the biochemical process of the complex nervous system. Current technologies for such applications, including microdialysis and fast-scan cyclic voltammetry, suffer from limited spatiotemporal resolution or poor selectivity. Here, we report a soft implantable aptamer-graphene microtransistor probe for real-time monitoring of neurochemical release.

Article Synopsis
  • Extensive research shows that high molecular weight neurochemicals, like neuropeptides, are crucial in various neurological disorders, but current detection methods are limited in small animal models.
  • A new wireless push-pull microsystem allows for membrane-free neurochemical sampling with cellular spatial resolution in freely moving animals, demonstrating high recovery rates.
  • This innovative device does not hinder natural mouse behavior and enables the capture of neuropeptide Y release, opening new avenues for studying neurochemical impacts on behavior.
