Cumulative cultural evolution has been claimed to be a uniquely human phenomenon pivotal to the biological success of our species. One plausible condition for cumulative cultural evolution to emerge is individuals' ability to use social learning to acquire know-how that they cannot easily innovate by themselves. It has been suggested that chimpanzees may be capable of such know-how social learning, but this assertion remains largely untested. Here we show that chimpanzees use social learning to acquire a skill that they failed to independently innovate. By teaching chimpanzees how to solve a sequential task (one chimpanzee in each of the two tested groups, n = 66) and using network-based diffusion analysis, we found that 14 naive chimpanzees learned to operate a puzzle box that they failed to operate during the preceding three months of exposure to all necessary materials. In conjunction, we present evidence for the hypothesis that social learning in chimpanzees is necessary and sufficient to acquire a new, complex skill after the initial innovation.

Background The dental faculty must understand the challenges students face in prosthodontics to enhance education and meet patient care demands. This study explored final-year Bachelor of Dental Surgery (BDS) students' perceptions, study methods, and clinical application of knowledge, identifying gaps in translating theory to practice, skill acquisition, and curriculum alignment. Insights guide improvements in mentorship, hands-on training, and active learning to enhance clinical preparedness.

This study utilized Bidirectional Long Short-Term Memory (BiLSTM) networks to predict mental health outcomes following concussion in youth and compared its performance to traditional models. We also examined whether incorporating social determinants of health (SDoH) improved predictive power, given the disproportionate impact of concussions and mental health issues on disadvantaged populations.

Historiography is a vital perspective of our scientific literature that charts the evolution of scientific publishing, from its early origins to the present status. The key transformations including the shift from a limited self-published legacy to specialized and professional peer-reviewed journals, the impact of technological advancements, and the emergence of new profitable business models are learning points for the future course and couture. Science is pursued and persevered by real humans in social and cultural contexts and not in isolation of laboratories or clinics.

Background: Unhealthy alcohol use is a leading cause of preventable mortality and a risk factor for an array of social and health problems. The Intervention in Small primary care Practices to Implement Reduction in unhealthy alcohol use (INSPIRE) study is part of a nationwide campaign to improve the identification and treatment of patients engaging in unhealthy alcohol use.
Methods: We conducted a single arm, pragmatic study consisting of seventeen primary care practices in the Chicago metropolitan area, Wisconsin, and California across two waves with a 6-month latent period, a 12-month intervention period, followed by a 6-month sustainability period.
