New research reveals that walking in longer, uninterrupted bouts of 10–15 minutes significantly lowers cardiovascular disease risk—by up to two-thirds compared to shorter strolls. Scientists from the University of Sydney and Universidad Europea found that even people who walk less than 8,000 steps daily can see major heart health benefits simply by changing how they walk. Those who took their steps in one or two continuous sessions had lower rates of heart attacks, strokes, and death.| ScienceDaily
Density is a measure of mass per unit of volume. Density is a measure of mass per volume. The average density of an object equals its total mass divided by its total volume. An object made from a comparatively dense material (such as iron) will have less volume than an object of equal mass made from some less dense substance (such as water). Perhaps the highest density known is reached in neutron star matter. The singularity at the centre of a black hole, according to general relativity, does...| ScienceDaily
