Environmental characteristics can influence aging. Democracy results in higher life expectancy for its members. However, there is a lack of research that indicates the influence of democracy on its leaders. Specifically, we examine how the nature of democracy affects the perceived aging of its leaders. In this paper, we capture perceived aging via face perception. We suggest that leaders in a democracy are perceived to age more compared to those in an autocracy. Counter to the common belief that democracies are less stressful, we find that the stress of being a leader in a democracy can have adverse effects. Study 1 uses picture pairs of 268 leaders from across the world, and participants judge age difference in years between the pictures. Study 2, a controlled study, examines downstream influences on the leader's specific attributes. Results indicate that leaders appearing to age more are more likely to avoid complex decisions, to be less charismatic, and to be less inspiring.

Introduction: In relatively wealthy countries, substantial between-country variability in COVID-19 vaccination coverage occurred. We aimed to identify influential national-level determinants of COVID-19 vaccine uptake at different COVID-19 pandemic stages in such countries.
Methods: We considered over 50 macro-level demographic, healthcare resource, disease burden, political, socio-economic, labor, cultural, life-style indicators as explanatory factors and coverage with at least one dose by June 2021, completed initial vaccination protocols by December 2021, and booster doses by June 2022 as outcomes.

Background: Nonhuman animals are regularly enhanced genomically with CRISPR and other gene editing tools as scientists aim at better models for biomedical research, more tractable agricultural animals, or animals that are otherwise well suited to a defined purpose. This study investigated how genome editors and policymakers perceived ethical or policy benefits and drawbacks for animal enhancement and how perceived benefits and drawbacks are alike, or differ from, those for human genome editing.
Methods: We identified scientists through relevant literature searches as well as conference presentations.

Language is acquired and processed in complex and dynamic naturalistic contexts, involving the simultaneous processing of connected speech, faces, bodies, objects, etc. How words and their associated concepts are encoded in the brain during real-world processing is still unknown. Here, the representational structure of concrete and abstract concepts was investigated during movie watching to address the extent to which brain responses dynamically change depending on visual context.
