Five health indicators are enough to predict cardiovascular risk in healthy people

A new study found that the Fuster-BEWAT score accurately predicts cardiovascular risk in healthy individuals, even without blood analysis. The score uses five health indicators: blood pressure, physical activity, BMI, fruit and vegetable intake, and smoking status.

When water met iron deep inside the Earth, did it create conditions for life?

Reservoirs of oxygen-rich iron between the Earth's core and mantle may have played a major role in shaping our planet's history. The discovery suggests that massive iron dioxide rocks could be generated annually above the core, releasing oxygen into the atmosphere, potentially triggering the Great Oxygenation Event.
