Testosterone has long been linked to risk-taking, generosity, and competitiveness. But a new large-scale study – the biggest of its kind – finds that men given testosterone made the same economic choices as those given a placebo.

Poorer health is linked to a higher proportion of votes for the populist right wing political party, Reform UK, indicates an analysis of the 2024 general election voting patterns in England, published online in the open access journal BMJ Open Respiratory Research. The findings should prompt policy-makers of all political stripes to step up efforts to improve public health and tackle health inequalities, suggest the researchers.
