A new review of brain scan studies reveals how digital devices shape young minds. While excessive scrolling is linked to structural brain changes and lower attention spans, some interactive gaming might actually boost specific cognitive skills. It turns out the type of screen time matters just as much as the duration.
A network meta-analysis of 25 clinical trials compares advanced weight-loss treatments. The data suggests that tirzepatide and CagriSema lead in average weight reduction, though higher doses correlate with increased mild gastrointestinal side effects.
Lead acts as a molecular imposter, mimicking calcium to sneak past biological defences during fetal development. This interference disrupts vital neurotransmitter pathways and alters brain connectivity. These changes are linked to higher risks of neurodevelopmental conditions like ADHD and autism.
A study of 215 countries reveals that as we build more green energy, our power grids face rising threats from extreme weather. Wind turbines are the most vulnerable, whilst South America faces the highest risk of damage. However, strong local institutions can help communities adapt and rebuild stronger.
