This study examined 7-to-13.5-month-old middle-class Western infants' visual orienting to third-party interactions in parallel with their social attention behavior during own social interactions (Leipzig, Germany). In Experiment 1, 9.5- to-11-month-olds (n = 20) looked longer than 7- to-8.5-month-olds (n = 20) at videos showing two adults interacting with one another when simultaneously presented with a scene showing two adults acting individually. Moreover, older infants showed higher social engagement (including joint attention) during parent-infant free play. Experiment 2 replicated this age-related increase in both measures and showed that it follows continuous trajectories from 7 to 13.5 months (n = 50). This suggests that infants' attentional orienting to others' interactions coincides with parallel developments in their social attention behavior during own social interactions.

Social bees, with their specialized gut microbiota and societal transmission between individuals, provide an ideal model for studying host-gut microbiota interactions. While the functional disparities arising from strain-level diversity of gut symbionts and their effects on host health have been studied in Apis mellifera and bumblebees, studies focusing on host-specific investigations of individual strains across different honeybee hosts remain relatively unexplored. In this study, the complete genomic sequences of 17 strains of Gilliamella from A.

Background: Neonatal abstinence syndrome (NAS), or withdrawal from prenatal opioid exposure at birth, can trigger a referral to child protective services (CPS). However, there is some evidence of selection into NAS diagnosis because NAS screening is not universal. Such referrals may protect the infant, help connect the mother to services, or cause harm.

Systematic social observation (SSO) is an objective method of measuring the neighborhood physical and social characteristics. This study aimed to build intraurban indicators using the SSO method and compare them between two slums and their surroundings in a Brazilian capital. The simple indicators were calculated using the ratio estimator method, and grouped into domains.

Bacterial social interactions play crucial roles in various ecological, medical, and biotechnological contexts. However, predicting these interactions from genome sequences is notoriously difficult. Here, we developed bioinformatic tools to predict whether secreted iron-scavenging siderophores stimulate or inhibit the growth of community members.

The formation of new social interactions is vital for social animals, but the underlying neural mechanisms remain poorly understood. We identified CeA neurons, a population in central amygdala expressing neuropeptide B/W receptor-1 (NPBWR1), that play a critical role in these interactions. CeA neurons were activated during encounters with unfamiliar, but not with familiar, mice.
