Economic Burden of Falls for 190 Countries and Territories From 2020 to 2050 Based on Health-Augmented Macroeconomic Modelling
A new health‑augmented macroeconomic model estimates that falls will cost the global economy about INT $3.939 trillion (≈ $3.9 trillion USD) between 2020 and 2050, representing roughly 0.088% of cumulative world GDP. The United States, China and Germany account for the largest absolute losses. Low‑ and middle‑income countries generate 74.8% of fall‑related DALYs yet only 32.6% of the projected economic loss, revealing a stark mismatch between health burden and monetized impact. The study calls for intensified fall‑prevention measures worldwide.
A Cluster-Randomized Trial of Labelled Cash Transfers for Uptake of Care for Chronic Conditions Among Middle-Aged and Older Adults in...
A cluster‑randomized trial in Burkina Faso tested whether small, labelled cash transfers would boost health‑service uptake among adults aged 45 and older with chronic conditions. The study enrolled 2,400 participants across 30 villages, offering a $10 (≈ USD 10) incentive conditional on...
Individual versus Group-Based Interventions: A Systematic Review and Meta-Analysis of Physical Activity, Functional, Psychosocial and Health Outcomes
A new meta‑analysis of 71 studies comparing individual and group‑based physical activity (PA) interventions found that group formats deliver a modest, statistically non‑significant advantage for overall activity, psychosocial, and health outcomes, but a significant benefit for functional measures after outlier...
Feature Selection Leads to Divergent Neurobiological Interpretations of Brain-Based Machine Learning Biomarkers
A new study in Nature Human Behaviour shows that the common practice of univariate feature selection in brain‑based machine‑learning models discards many informative connections. By partitioning connectome edges into ten non‑overlapping deciles, the researchers demonstrated that mid‑ranked and lower‑ranked feature...
How Deceptive Online Networks Reached Millions in the US 2020 Elections
A study published in Nature Human Behaviour finds that deceptive online networks reached at least 37 million Facebook users and 3 million Instagram users during the 2020 U.S. elections, representing roughly 15% of adult Facebook users and 2% of Instagram users. Three...
Shifting From Brain Ageing to Brain Longevity
In a recent Nature Human Behaviour comment, Sara Palermo argues that societies should move from viewing brain ageing as inevitable decline to treating it as brain longevity, a form of capital. She draws on neuroscience and behavioural science to propose...
Premature Termination of Unemployment Benefits Increased COVID-19 Transmission and Deaths in the USA
A new study in Nature Human Behaviour finds that states that ended pandemic unemployment insurance (UI) in summer 2021 saw sharp spikes in COVID‑19 outcomes. Weekly case rates rose by 0.18 percentage points, hospitalizations increased by 0.18 per 1,000, and deaths grew...
Integrating Behavioural Experimental Findings Into Dynamical Models to Inform Social Change Interventions
The paper proposes a framework that fuses behavioural experiment results with dynamical systems models to better predict and steer collective social change. By grounding threshold and cascade models in empirical decision‑making data, the authors show how interventions can be calibrated...
Large Language Models Have the Potential to Level the Playing Field in Consumer Financial Complaints
A new research briefing examined 1.13 million US Consumer Financial Protection Bureau complaint narratives and found that large‑language‑model (LLM) assistance surged after ChatGPT’s release. The study shows LLM‑assisted complaints are more likely to secure consumer relief, with a measurable uplift in...
A Crowdsourced Megastudy of 12 Digital Single-Session Interventions for Depression in US Adults
The researchers conducted a crowdsourced megastudy that tested 12 digital single‑session interventions (SSIs) for depression among a large U.S. adult sample recruited online. Using a preregistered design, three of the SSIs produced statistically significant reductions in depressive symptoms, with effect...
Low Fertility May Persist and Could Be Good for the Economy
A new study argues that persistently low fertility in high‑income countries may be economically beneficial. The authors note that total fertility rates have fallen below replacement and often under 1.3, a level once thought temporary. Cross‑sectional data show a positive...
