Haiti study suggests early-onset heart failure is prevalent form of heart disease in low-income countries

A Weill Cornell Medicine study found that over 15-fold more Haitians have early-onset heart failure than previously thought, with elevated blood pressure being the leading risk factor. The research suggests a shift in focus to early prevention and treatment of cardiovascular diseases in low-income countries.

Climate change disrupts vital ecosystems in the Alps

Scientists have found that climate change is altering the timing of plant and soil processes in the Alps, leading to disruptions in nutrient cycling and potentially threatening biodiversity. The high mountains are warming at a faster rate than surrounding areas, resulting in reduced snow cover and changes in vegetation patterns.
