Researchers at the University of Bath in the UK are proposing thresholds for safe – or at least safer – cannabis use and hope their findings will help people monitor consumption and keep it within recommended limits – similar to how alcohol units guide safer drinking.
A new interdisciplinary study led by researchers from Nanyang Technological University, Singapore (NTU Singapore), with collaborators from the City University of Hong Kong, has found that El Niño events significantly reduce life expectancy across high-income Pacific Rim countries, resulting in economic losses of up to US$35 trillion by the end of the 21st century.
Using over six decades of mortality records from 10 high-income Pacific Rim countries, the research team shows that El Niño is a persistent driver of health and economic loss, not just a short-term weather anomaly. El Niño-driven climate extremes, such as heatwaves and air pollution, disrupt healthcare systems and raise long-term mortality risks, particularly among vulnerable populations.
The research, published in the scientific journal Nature Climate Change and part of NTU’s Climate Transformation Programme, shows that El Niño events not only cause immediate health impacts but also persistently slow long-term improvements in mortality rates, leading to enduring reductions in life expectancy.
The study proposes LA-TextCNN-BiLSTM, an ICD-11 automatic coding model using MC-BERT and label attention. Experiments on clinical records show 83.86% accuracy, 75.82% macro-F1, and 82.83% micro-F1. The model effectively handles long-distance dependency and Chinese semantic diversity in electronic medical records.
Veteran male athletes who have spent years training at high intensity may be at greater risk of serious heart problems while exercising, new University of Leeds research shows. The study shows that male endurance athletes aged over 50 may be more likely to experience abnormal heart rhythms during training if they already have scarring in their heart. The team says their research shows that exercise itself is not dangerous - but the findings suggest that the presence of scar tissue in the heart increases the risk of potentially dangerous heart problems during physical activity.
