At the World Health Summit, diversity in representation is increasing — but influence remains uneven. Drawing on 11 years of speaker data from one of the most prominent global health forums, we uncover patterns in gender, geography and sector. We propose three areas for future reform to ensure global health platforms move beyond tokenism towards meaningful inclusion and accountability.

Emotional events tend to be vividly remembered. While growing evidence suggests that emotions have their basis in brain-wide network interactions, it is unclear whether and how these whole-brain dynamics contribute to memory encoding. Here we combined functional MRI, graph theory, text analyses and pupillometry in a naturalistic context where participants recalled complex narratives in their own words. Across three independent datasets, emotionally arousing moments during narrative perception were associated with an integrated brain state characterized by increased cohesion across functional modules, which in turn predicted the fidelity of subsequent recall. Network integration mediated the influence of emotional arousal on recall fidelity, with consistent within- and between-network interactions supporting the mediation across datasets. Together, these results suggest that emotional arousal enhances memory encoding via strengthening functional integration across brain networks. Our findings advance a cross-level understanding of emotional memories that bridges large-scale brain network dynamics, affective states and ongoing cognition.

Psychometric network models have become increasingly popular in psychology and the social sciences as tools to explore multivariate data. In these models, constructs are represented as networks of observed variables, and researchers often interpret the presence or absence of edges as evidence for or against conditional associations between variables. However, the statistical evidence supporting these edges is rarely evaluated. Here we show that a large proportion of reported network findings is based on weak or inconclusive evidence. We reanalysed 293 networks from 126 published papers using a Bayesian approach that quantifies the evidence for each edge. Across the studies, one-third of edges showed inconclusive evidence (1/3 < inclusion Bayes factor (BF10) < 3), about half showed weak evidence (BF10 > 3 or BF10 < 1/3) and fewer than 20% were strongly supported (BF10 > 10 or BF10 < 1/10). Networks based on relatively large sample sizes yielded more-robust results. Our study shows that networks are often supported by too little evidence from the data for the results to be reported with confidence, not meaning that the results are flawed but, rather, suggesting caution in interpreting individual edges.

The adverse effects of climate change will be worse in some locations than in others, raising the possibility that migration from more severely impacted areas to less impacted areas will reduce future damages. Assessing whether such migration is already occurring can inform our understanding of future responses to climate change. Using data on the paths of all Atlantic basin hurricanes and tropical storms from 1992 to 2017, we study whether outmigration from US counties increases after a storm. On average, storms are not followed by outmigration, and total population-weighted exposure to storms increases over the sample period. Very destructive storms are followed by outmigration, though often to other high-risk counties. Counties with high economic activity see net in-migration after a storm. Given existing policies and incentives, the economic and social benefits of high-risk areas currently appear to outweigh the incentive to reduce exposure to future storms by relocating across counties. Population-weighted exposure to tropical storms and hurricanes increased in the USA between 1992 and 2017. The attractions of high-risk areas currently outweigh incentives to reduce exposure to future storms through migration.

Efficient algorithms can enhance problem-solving in many cognitive domains but can be difficult to discover and use. For example, classical studies of seriation suggest that children struggle to apply algorithmic strategies in a simple sorting problem. We investigated the spontaneous discovery of algorithmic solutions across development. We gave children a variant of the sorting problem with hidden object ranks: children sort animated bunnies into the right order, from the shortest to the tallest, when the bunnies are standing behind a wall so their heights are not visible. Children performed far above chance on this difficult sorting task, potentially because higher demands in memory and reasoning incentivized strategic behaviours. Children also independently discovered at least two efficient algorithmic solutions to the sorting problem: selection sort and shaker sort. Additionally, our developmental results show that older children were more effective sorters than younger children and used efficient sorting algorithms more frequently. These results indicate that children are far more competent at applying algorithmic solutions to sorting tasks than previous research would suggest, and performance on sorting tasks improves throughout development. Our work demonstrates that children have the ability to spontaneously organize their behaviours and find effective solutions to challenges in the world. Children successfully solved a challenging sorting task by spontaneously discovering efficient sorting strategies, such as selection sort and shaker sort. Older children outperformed younger ones, demonstrating developmental progress in strategic thinking and problem-solving abilities.

Formal education systems rarely include the knowledge and skills of hunter-gatherer societies. This can lead to cultural erosion and knowledge decline. For education to be both high quality and sustainable, Indigenous knowledge should be recognized and valued.

Advanced artificial intelligence (AI) systems capable of generating humanlike text and multimodal content are now widely available. Here we ask what impact this will have on the democratic process. We consider the consequences of AI for citizens’ ability to make educated and competent choices about political representatives and issues (epistemic impacts). We explore how AI might be used to destabilize or support the mechanisms, including elections, by which democracy is implemented (material impacts). Finally, we discuss whether AI will strengthen or weaken the principles on which democracy is based (foundational impacts). The arrival of new AI systems clearly poses substantial challenges for democracy. However, we argue that AI systems also offer new opportunities to educate and learn from citizens, strengthen public discourse, help people to find common ground, and reimagine how democracies might work better. This Perspective from Summerfield et al. considers the impacts of advanced artificial intelligence systems on the process and function of democracy. The authors explore a wide range of potential risks and opportunities.
