A randomized controlled trial in rural Burkina Faso found no evidence that providing small labelled cash transfers to support healthcare visits for individuals with chronic non-communicable diseases improved their care linkage or treatment uptake.

Using a health-augmented macroeconomic model, Li et al. estimate the global economic burden of falls and reveal substantial, unevenly distributed output losses.

Using racing diffusion models to analyse 115,601 implicit association tests across 39 topics, LaFollette et al. found that response caution explained more variance in D-scores than decision ease.

Across more than 12,000 MRI scans, the authors show that features discarded during feature selection can rival top-ranked ones in predicting behaviour yet imply different brain circuits, warning that focusing only on top features can mislead neurobiology.

A systematic review and meta-analysis compares the effects of individual and group-based approaches on physical activity, functional, psychosocial and health outcomes.

Appel et al. found that deceptive networks reached over 37 million Facebook and 3 million Instagram users during the 2020 US elections, with the majority of this exposure driven by 3 networks and amplified by ordinary users resharing the content.

Population ageing is too often framed as decline. Drawing on neuroscience and behavioural science, this Comment calls for a shift from brain ageing to brain longevity and argues that brain capital should be treated as a policy and governance priority to support resilient institutions and sustainable economies.

Researchers from authoritarian academic backgrounds often exhibit self-censoring microbehaviours, which cause difficulties when transitioning to nonauthoritarian environments, explains Myint Thu.

Neuroscience is crucial for understanding human behaviour. Yet, its resource-intensive methods contribute to the climate crisis. We call on neuroscientists to align their research with ecological sustainability goals across the research cycle and propose three key steps: replace unfocused data collection, reduce excessive emissions and refine imprecise methods.

Living systematic reviews continuously integrate new research and can provide timely evidence for policy and practice. This format adds value beyond traditional systematic reviews, and we recommend its wider adoption.

Behavioural genetics is prone to harmful misinterpretation. To counter this and its consequences, behavioural geneticists must engage with the communities that they serve, and communicate clearly, responsibly and frequently to build and retain trust. It is crucial that this growing field promotes ethical, inclusive discovery.
